Back in the 90’s I had a 1986 RX7. I loved it. To fix the flooding issue, You pull the fuse to the fuel pump. Turn the engine over a few times. Then put the fuse back in. I had to do this all the time. My friends always wondered what in the world I was doing.
The low rotational mass isn't the reason for lack of torque. It's the short moment arm between where the combustion is acting on the rotor and the eccentric shaft. Piston engines generally have a much longer moment arm between the top of the piston and the crankshaft. Think about using a breaker bar from the very end vs. a few inches from where the socket attaches.
I have an 05 rx8 and I fell victim to flooding the engine. 2 ways I learned to "fix" it was taking the fuel pump relay out (I think) and letting the gas flow back into the tank. Second, the rx8's have a built in cut off for fuel when the gas pedal is all the way to the floor when the car is off. So cranking the engine with the gas pedal down cuts fuel, and helps deflooding. =]
Here is a tip to unflood your rotory. Pull the two fuses on the top right corner under the hood. Floor the gas pedal and crank the motor for at least ten seconds. Put fuses back in and try to start. May need to do it a couple times
I know this isn’t cheap but if you install a Haltec Sprint Re into your rx7 ging you’ll fucking love it, especially when you do the swap it makes your life 100x easier for an engine harness, I can send you proof of my t2 swap in a n/a body
Ight ive only been following gingium since the rally miata and ive been loving this channel, now this big dude that has apparently been on here before is back im loving it 10x more
Fun FACT! Inside the housing, it has a small hole on the top right corner. Thats where the oil comes out of to lubricate the apex seals. Didnt hear u guys mention it. So just fyi
The main thing limiting rpm on typical engines is the valves. The moving mass and the springs give hard limits to how fast the camshaft can spin without the valves staying open more than the length they are supposed to. Also sucks if you destroy any part of said valves. The pistons also have a limit, but it's much higher. Piston engines designed for it or that don't use valves can safely rev much higher.
Better way to unflood the engine is to unplug the fuel relay fuse at one of the edges of the fusebox under the hood, crank the engine with the key in ignition a few times, place the fuse back where it was and go for a startup. Works every time.
Rotaries are cool and all, one of my family members had a 1980 FB RX-7, more specifically it was my father who had a 1980 FB with a 2 rotor and a 5 speed. It was a bad ass car.
That unfolding procedure is only for severely flooded and probably already low compression engines. In an FC you can just pull the fuel pump relay in the engine fuse box and crank the car for 10 seconds with the gas flat then pop the fuse back in and it will fire up immediately.
You can also put motor oil in your gas tank instead of 2 stroke premix because it's cheaper. I've done that with my two strokes and it's all ways worked perfectly
way back in the early 2k's a friend of mine got an rx7 with a "blown engine" "ruined engine" for $150 from the father of the guy who was the "owner" was sure it was toast and needed a new engine... the kid talked to some people on a forum, ordered what they said would be needed to rebuild it... most of the parts came from a local shop that specializes in stuff like the rx7 era cards, not all are rotary, when i went with him to pick stuff up, the owner and one of the head mechanics talked to us, got my buddies info, they showed up a few hours later to look at our progress, my buddy was in a mechanics course at the community college threw the highschool to college program, the instructor insisted you couldnt rebuild a rotary, just had to swap them... well.. the shop guys stopped by, inspected the engine parts and... helped us swap the apex seals and... told us to return the rest, none of it was needed, the rest looked great, the seals were shot, they even stuck around and supervised us, both shocked we were computer geeks doing mechanic work.... even more shocked when one saw me rebuilding a carb as we talked... i hadnt even realized i started to do it, since i was waiting on the other guys to get hoses and wires hooked back up... first try it started up and ran great... infact the guys had him bring it in, they put it on their dyno and tested it, found it was above average for an factory stock engine(top end model but still....), because it was both his college project for his degree, and his sr project for highschool, the shop helped him out, by letting him intern in trade for parts, a couple times, installing grand new high end parts rather then the 2nd hand parts he had them lay aside for him.. that car by the time he presented it for both his degree project and his sr.project for highschool was not only running like new, he had upgraded it a bit himself, and rather then swap his suspension for the stuff he had them sat aside from a couple auction and "Scrap" (parts) cars he helped them part out... he came back after a vaction with his family to find they had used one of their top end, non-custom kits(its custom for the car but not made to order type custom), hes still driving it as his daily driver decades later, very proud of that car, the apex have needed replaced twice since, both times i helped, thought the last time... dudes 14yo step son, fucking took charge, and got it done faster then we would have, after helping out alot with the cars and wrenching, just take a guess what the kids asked for, for his first car, if they can find one in decent shape? yup, one like "dads" and, yeah, the kid was 10 when mom met my buddy, his bio fathers a real shit stain who was really upset to find out that his son, called step dad, dad, when he calls his bio father by his first name LoL... anyway.... my buddy already had a line on an rx7 that needs some TLC and the engine def needs seals, if not more, hopefully just seals...but... his kids going to do the restoration as his sr project "if i get the car", his sons got over 12k he saved himself and another 15k grandma left each of the grandkids for a car or similar, she also setup a trust that pays on the grandkids college expenses as long as they keep their grades up, shes not dead but she got it all taken care of decades ago after a breast cancer scare, she actually said she would kick in on getting him a car in good shape, then he understood and sad she would help cover the cost of restoration/modding/etc as long as "dad" looks over and approves everything first, so he wont have to hit his personal savings, hes leaving the money she left them in the high interest account unless he really needs it, his sister bought a crappy car(that looked pretty) and ended up broke after having to have it worked on over and over...eventually she did trigger the lemon law and the dealership gave her a much more reliable car...thats that shade or brown-green that babyshit often is... and is a nissan cube... she hated it at first "im driving a box"... now she loves it... so yeah... anyway, his father got a 80's nissan/datsun Z car...not the 300..280 or something... the one that didnt look as plastic toy car like, anyway, hes engine was so blown, when we took all the bolts out of it, the block was in 6-7 pieces ..heads cracked in 3 pieces.... what was weird, the tranny, outside broken bellhousing, was found to be sound...the tranny shop actually gave him a good trade in on the custom tranny they had from a client who died before it was done, and, whos son told them to 'stuff it' for asking the price dad agreed to pay..... for a few hundred and the tranny they were going to rebuild or use for parts, he got a tranny with 6 forward gears, and 3 reverse... high range...almost as fast as second is in forward, but in reverse.. r2 is slower with more torque, r3 is... max torque... he later learned that the old guy used it in, i think it was an AMC Eagle Station Wagon, with a tow setup on the front so he could just drive the boat down to the water without backing in, apparently he allowed somebody to borrow it when he was out of town, and they didnt check the fluids leading to the tranny needing rebuilt(or at least serious servicing), his plan now is to stick a rx7 engine he has thats one pulled from a car in japan due to milage, thats "refurbished" any parts that could wear/show wear, replaced, he got 3 unopened crates for 300usd each years ago, has had them all bench tested to ensure they worked before he paid for them.... hes gonna tell his step son, that if he wants to make the engine swap project his sr.project, that they can see about finding another rx7 thats in better shape and dosnt need the insides re-done(seats, carpets, etc, all really bad... really really bad... not taken care of, and had smokers melt holes in the seat covers... stuff like that... a car he can use the one hes already got a cheap line on, as the parts car when rebuilding it.) anyway, hes said, im the first person outside family that will get to drive the RotaryZ, Z_Wankle, Wankle Z.... hehe... genuinely cant wait... the z car he got that cheap, already has prof installed suspension, better breaks, even an unobtrusive, and as they later learned from one of the mazda shop guys... a very expensive custom installed rollcage... whatever happened to that engine... it didnt break any engine mounts....just... the engine looked like somebody dumped Ln2 on it and droped it on its head... just "how does that even happen"...a nissan shop in portland bought that off him to examine but also, to display... apparently nissan sent over people to examine and document the engine... i gather..one of the guys ended up sitting down on a step stool just looking threw the glass at the parts on display, and later told them, he was part of the team back in the day who designed that engine, and, when he heard about it, and saw the pictures, he had to see it himself.. cant really blame them... i have seen some weird shit but.. thats next level weird.. it was just...broken... very broken...
To anyone wondering how to deflood: S5 FC and further have a built in system, all you need to do is floor the gas when cranking and it cuts fuel. S4 and older, you can pull the EGI relay. If you need to turn on a rotary briefly and don't want it to flood, rev to 3000 and turn the engine off while it's there. I've never flooded my SA, FC or FD
There's something wrong with his car if it's getting 15 mpgs. Check your coolant temp sender on the back of the water pump housing. My FD gets 13-18, and my NA FC used to get 20.
I would like to say, enjoyed this video a lot. Like the humor, editing, and knowledge. Extremely rare to see a video of this quality. Never heard of you guys before but i'll take a look.
Its not a 1.3L.. see this misconception everywhere. Mazda said the space at tdc (or how you call it for rotaries) is 666cc big. With two of them that gives about 1.3 liters. But for ONE full rotation (which is equal to one full stroke for a piston engine) So per rotation you have 3x666cc by two disks/rotors. Gives you about 4 liters. 4 liter NA has its fuel consumption:)
Yayy someone else knows the truth! And torque is not made by mass of the motor but instead the length of the stroke hits why a a bit v8 makes torque and a honda makes HP
Yeah but thats kind of an unfair comparison as well because it takes 1080 degrees of rotation to go through those 3.9L. For 2 rotations of the eccentric shaft it displaces 2.6L, so comparing a 13B to 2.6L piston engine is the most fair comparison in my opinion
Kenny Wood but really it can't be compared at all because its an entrely different mechanism. Working off pure external figures, they're inferior Higher harmful emissions, high fuel consumption in regards to power generated, uses alot of oil (even if its by design because thats a silly idea) I mean yeah, they can have their place but not for an average mans car
my cousin owned one and i honestly want one after riding in his. its actually a funny because when he was looking at cars years back i was mentioning some random cars and he surprisingly didnt know too much about rx7's and chose one. i went with him down and we got it and on the way home i was just like " its crazy how theres basically two triangles spinning in this engine right now " and he was like "what ? " he legit had no idea what a rotary engine was and after that he became obsessed with rotary cars. and its like now i want an fd.
you can just disconnect the fuel pump relay turn it over and put the relay back in a there you go your car will now start, if you dont have the 2 stoke fuel of course
To un flood a rotary another thing you can do is pull the injector fuse crank it for a few seconds then put the fuse back and it should start it works with my FC
And a quicker way to unflood the car is to pup the hood and go to the fuse box and pull the EGI fuse. Turn the car over for 10-15 sec. Wait 10 sec then repeat like 3-4 times. Put fuse back in and try to start. You can also wire in a switch for your fuel pump and just shut it off, crank the car over to clear, then turn the fuel pump back on and try to start it. Kinda a nice theft prevention also.
This flood happens cause of a fluke in the ecu where it gets stuck in the cold start warmup process and makes it highly likely to flood during the next start.
I had a fc rx7 if it floods pull the injector relay turn it over a few times plug it back in it'll fire right up it also helps to rev It Up before you turn it off
If you flood the engine you can purge pure oxygen gas into the intake to get the right mixture with the extra gasoline in the engine. But keep your distance in case the engine explodes.
Mine was previously heavy neglected. 3 inch straight pipe. Dropped into first at 7k rpm always. Seals went, clutch went, suspension went. And not to mention it sounded like a lawn mowet
The rotaries don't have that much torque because the eccentricity of the shaft is pretty small and non variable, unlike the stroke of a piston engine. If you changed it it wouldn't allow for the weird epitrochoid around the rotor to create a seal, not because it is light. Reciprocating assemblies can also be light and produce tons of torque. Where a heavy assembly helps is dragster launches, where you rev the engine and when you throw in the gear, the inertia of a heavy assembly let's all that power be transferred to the diff and tires without major losses. Great video though guys!
Injectors don’t stop right away when you turn the ignition off.. s5 if you wot right when you turn the key off it fuel cuts so it doesn’t flood on cold starts if you turn it off. S4 does not had that feature. Also cooling is extremely import on top of oil
According to the Mazda Owners Manual, do these steps to prevent flooding: With engine already running, 1. Raise the engine speed to 3000RPM 2. Holding the engine speed at 3000RPM, turn the ignition key to the “off” position, 3. While simultaneously depressing the gas pedal all the way down. 4. After the engine has completely wound down, release the gas pedal.
I would say low cubic volume is the reason for low torque. 1.3L is just not going to have grunt. The length of time that the power cycle is occurring directly affects torque output. Rotary's have a very short power cycle and it's pushing the rotor at an angle as oppsed to a piston that moves straight down on a power stroke.
Since these burn oil, how about putting bacon fat as the oil as it turns out to have even less wear than usual oil as engine oil? I would attempt it on a rotary engine for an all around improvement.
An easier way to un-flood your rotary is to just pull the EGI fuse and crank the car for like 15-20 seconds. Obviously won’t work if your car is severely flooded but you get the point. Did it plenty of times on my old FC. God I miss that thing :(
It’s like short stroke vs long stroke engines, where short stroke revs harder but has less torque. The rotary in a way has the shortest stroke possible, so is all revs and no torque
Gingium put a bigger rotary engine in it and put one big turbo or two to make it insaneeeeeeeee , btw great content keep it going bruh , more power to your channel
Yup, take care of them and they will last. I had one rebuilt years ago, and with basic maintenance and plenty of oil over the years its at about 230k on the rebuild. Ive been cross country with it and all kinds of other road trips. Yeah ya cant carry a whole lot but damn is it fun to drive all over the place.
The fuel injectors also spray in a much wider area than the omp does. It's far superior to premix. You should premix even with the omp just less ratio.
Hey Caleb, you should try a fuel system cleaner it might give you better mpg because that's really low mpg for a rotary. Also love the videos man keep up the good work
Even with a bridge port after it's tuned you can expect to see higher fuel efficiency. My fd stock only got about 15 city. Now I get 20 in the city and almost 30 on the highway
I have a suggestion, can you pls build some kind of old american muscle car or atleast a car from the late 60's to late 80's muscle car. Make it a drag car or highway racing. Cool vids btw gingium keep up the good work

Cody Smith nope. That happens when you're too stupid to tighten them.
that is not rotary problem that is gingium stupidity

Carbon fiber hood when?
I have autism please be patient hopefully he won't do that though
Nino why? Weight reduction and it looks fucking mint
Nino in the video he actually said he might do it lmao
Lol this car is gone 😂
i love how Shooting Cars is always in the rotary videos that gingium uploads
Here is a tip to unflood your rotory. Pull the two fuses on the top right corner under the hood. Floor the gas pedal and crank the motor for at least ten seconds. Put fuses back in and try to start. May need to do it a couple times
When you flood your rx8 you can push the gaspedal down fully then crank it. The ecu wont inject fuel as you are giving full gas.

Hey, y'all can get an oil pan heater, it's like a block heater, but it heats your oil up. Which helps with cold starts! 😊🙂
Better way to unflood the engine is to unplug the fuel relay fuse at one of the edges of the fusebox under the hood, crank the engine with the key in ignition a few times, place the fuse back where it was and go for a startup. Works every time.
To avoid flooding install a switch that turns off the fuel pump and stop the engine with that!

way back in the early 2k's a friend of mine got an rx7 with a "blown engine" "ruined engine" for $150 from the father of the guy who was the "owner" was sure it was toast and needed a new engine... the kid talked to some people on a forum, ordered what they said would be needed to rebuild it... most of the parts came from a local shop that specializes in stuff like the rx7 era cards, not all are rotary, when i went with him to pick stuff up, the owner and one of the head mechanics talked to us, got my buddies info, they showed up a few hours later to look at our progress, my buddy was in a mechanics course at the community college threw the highschool to college program, the instructor insisted you couldnt rebuild a rotary, just had to swap them... well.. the shop guys stopped by, inspected the engine parts and... helped us swap the apex seals and... told us to return the rest, none of it was needed, the rest looked great, the seals were shot, they even stuck around and supervised us, both shocked we were computer geeks doing mechanic work.... even more shocked when one saw me rebuilding a carb as we talked... i hadnt even realized i started to do it, since i was waiting on the other guys to get hoses and wires hooked back up... first try it started up and ran great... infact the guys had him bring it in, they put it on their dyno and tested it, found it was above average for an factory stock engine(top end model but still....), because it was both his college project for his degree, and his sr project for highschool, the shop helped him out, by letting him intern in trade for parts, a couple times, installing grand new high end parts rather then the 2nd hand parts he had them lay aside for him.. that car by the time he presented it for both his degree project and his sr.project for highschool was not only running like new, he had upgraded it a bit himself, and rather then swap his suspension for the stuff he had them sat aside from a couple auction and "Scrap" (parts) cars he helped them part out... he came back after a vaction with his family to find they had used one of their top end, non-custom kits(its custom for the car but not made to order type custom), hes still driving it as his daily driver decades later, very proud of that car, the apex have needed replaced twice since, both times i helped, thought the last time... dudes 14yo step son, fucking took charge, and got it done faster then we would have, after helping out alot with the cars and wrenching, just take a guess what the kids asked for, for his first car, if they can find one in decent shape? yup, one like "dads" and, yeah, the kid was 10 when mom met my buddy, his bio fathers a real shit stain who was really upset to find out that his son, called step dad, dad, when he calls his bio father by his first name LoL... anyway.... my buddy already had a line on an rx7 that needs some TLC and the engine def needs seals, if not more, hopefully just seals...but... his kids going to do the restoration as his sr project "if i get the car", his sons got over 12k he saved himself and another 15k grandma left each of the grandkids for a car or similar, she also setup a trust that pays on the grandkids college expenses as long as they keep their grades up, shes not dead but she got it all taken care of decades ago after a breast cancer scare, she actually said she would kick in on getting him a car in good shape, then he understood and sad she would help cover the cost of restoration/modding/etc as long as "dad" looks over and approves everything first, so he wont have to hit his personal savings, hes leaving the money she left them in the high interest account unless he really needs it, his sister bought a crappy car(that looked pretty) and ended up broke after having to have it worked on over and over...eventually she did trigger the lemon law and the dealership gave her a much more reliable car...thats that shade or brown-green that babyshit often is... and is a nissan cube... she hated it at first "im driving a box"... now she loves it... so yeah...

You can also do a fiberglass hood if you want a more cost affective option
on a series 5, you unflood flood them by pressing the gas while cranking. on series 4 you pull a fuse.
To anyone wondering how to deflood: S5 FC and further have a built in system, all you need to do is floor the gas when cranking and it cuts fuel. S4 and older, you can pull the EGI relay. If you need to turn on a rotary briefly and don't want it to flood, rev to 3000 and turn the engine off while it's there. I've never flooded my SA, FC or FD

you can just disconnect the fuel pump relay turn it over and put the relay back in a there you go your car will now start, if you dont have the 2 stoke fuel of course

To un flood a rotary another thing you can do is pull the injector fuse crank it for a few seconds then put the fuse back and it should start it works with my FC
And a quicker way to unflood the car is to pup the hood and go to the fuse box and pull the EGI fuse. Turn the car over for 10-15 sec. Wait 10 sec then repeat like 3-4 times. Put fuse back in and try to start. You can also wire in a switch for your fuel pump and just shut it off, crank the car over to clear, then turn the fuel pump back on and try to start it. Kinda a nice theft prevention also.
This flood happens cause of a fluke in the ecu where it gets stuck in the cold start warmup process and makes it highly likely to flood during the next start.
When my Rx7 flooded I just took out the egv fuse, cranked it 3 times, put it back in and it ran fine
I don't feel like explaining it but a 13b can also be classified as a 2.6L as well go watch a video on rotors magazine channel to see why
Zach should be in more video's
I had a fc rx7 if it floods pull the injector relay turn it over a few times plug it back in it'll fire right up it also helps to rev It Up before you turn it off
MY 70cc bike back fires too. AND I LOVE it
Oh yeah, that new vid feeling that you get from gingium.
the cold start problem for flooding can be fixed with fully pressing the throttle to 3000rpm and turn the car off as soon as it hits 3000
the guy with the red hat is hilarious why is he not around all the time lmao
If you flood the engine you can purge pure oxygen gas into the intake to get the right mixture with the extra gasoline in the engine. But keep your distance in case the engine explodes.
Stroke length determines torque not mass. Mass just eats up the torque. But I think its easy to mess up.
The heavy hood is for the light engine so it gets better grip
For some reason I like the adventure bus better than rally miata and rx7 videos. Bus video are some much better to watch
i 100% agree, not saying the other vids are bad tho
Bandit 3076 I think it’s because a lot of other people do videos on miata’s and drift cars
Bandit 3076 same
You are correct. Every youtuber is doing miatas and drift cars. It’s nice to see something different for once. Even when he did the off-road race.
The difference is that the bus videos are builds...those are the best videos, but they are too expensive to make :(
Mine was previously heavy neglected. 3 inch straight pipe. Dropped into first at 7k rpm always. Seals went, clutch went, suspension went. And not to mention it sounded like a lawn mowet
And a fuel cut off switch helps to not flood your rotory
Premixing might help you increase mpg. It'll also help the engine last longer. I recommend idemitsu premix
The rotaries don't have that much torque because the eccentricity of the shaft is pretty small and non variable, unlike the stroke of a piston engine. If you changed it it wouldn't allow for the weird epitrochoid around the rotor to create a seal, not because it is light. Reciprocating assemblies can also be light and produce tons of torque. Where a heavy assembly helps is dragster launches, where you rev the engine and when you throw in the gear, the inertia of a heavy assembly let's all that power be transferred to the diff and tires without major losses.
Great video though guys!
Injectors don’t stop right away when you turn the ignition off.. s5 if you wot right when you turn the key off it fuel cuts so it doesn’t flood on cold starts if you turn it off. S4 does not had that feature.
Also cooling is extremely import on top of oil
3:37 Extreme Tuning?
According to the Mazda Owners Manual, do these steps to prevent flooding:
With engine already running,
1. Raise the engine speed to 3000RPM
2. Holding the engine speed at 3000RPM, turn the ignition key to the “off” position,
3. While simultaneously depressing the gas pedal all the way down.
4. After the engine has completely wound down, release the gas pedal.
The torque issue was such a big complaint so mazda added the twin sequential turbos to fix that issue and they did a damn good job
I would say low cubic volume is the reason for low torque. 1.3L is just not going to have grunt. The length of time that the power cycle is occurring directly affects torque output. Rotary's have a very short power cycle and it's pushing the rotor at an angle as oppsed to a piston that moves straight down on a power stroke.
Since these burn oil, how about putting bacon fat as the oil as it turns out to have even less wear than usual oil as engine oil? I would attempt it on a rotary engine for an all around improvement.
0:40 your right headlight motor is slower.
An easier way to un-flood your rotary is to just pull the EGI fuse and crank the car for like 15-20 seconds. Obviously won’t work if your car is severely flooded but you get the point. Did it plenty of times on my old FC. God I miss that thing :(
It’s like short stroke vs long stroke engines, where short stroke revs harder but has less torque. The rotary in a way has the shortest stroke possible, so is all revs and no torque
Rotary = Triangle = Illuminati = Half Life 3 Confirmed
Liam Schwarz which is good because the people who made half life said hl2ep2 is the end
Still don’t have it 6 years later 😖
Gingium put a bigger rotary engine in it and put one big turbo or two to make it insaneeeeeeeee , btw great content keep it going bruh , more power to your channel
I've always wanted an FC. Glad to hear they're not the nightmare everyone says they are
Out of all the videos I have seen on rotary engines this makes the most sense! Haha
The rotary brothers of america! Merry Christmas Gingium
If you turn on auto captions at 1:17 when he revs and launches it say “Music” In the captions.... I totally agree that rotaries sounds like music
Still love the rx7 just need more vids on it
Yup, take care of them and they will last. I had one rebuilt years ago, and with basic maintenance and plenty of oil over the years its at about 230k on the rebuild. Ive been cross country with it and all kinds of other road trips. Yeah ya cant carry a whole lot but damn is it fun to drive all over the place.
The fuel injectors also spray in a much wider area than the omp does. It's far superior to premix. You should premix even with the omp just less ratio.
Loved the live example
Flamium🔥
Loving that gray paint.
Hey Caleb, you should try a fuel system cleaner it might give you better mpg because that's really low mpg for a rotary. Also love the videos man keep up the good work
Even with a bridge port after it's tuned you can expect to see higher fuel efficiency. My fd stock only got about 15 city. Now I get 20 in the city and almost 30 on the highway
Makaio Salazar wow that is a big increase
BRAAAP
...ium
The beat go BRAAAP. BRAP BRAP BRAP BRAP BRAP. I’m sorry
Stututu
BRAPAPAPAPA
You can pull the fuse under the hood & crank it for a few seconds it will start
Doctor Zach was throwin it down!
can you take a tour around your shop? there are alot of interesting junk there
We need more merchium!
I never actually thought of this but rotarys are the 2 strokes of the car world
Fix your exhaust where it hangs or a new one would be nice
I just watched the whole lifted miata series and the molly series and bus. Doing good on the bus
Just about to go to bed then your video came up it's nearly 12am here in Australia
Did it just shoot flames on a stock engine?
I have a suggestion, can you pls build some kind of old american muscle car or atleast a car from the late 60's to late 80's muscle car. Make it a drag car or highway racing. Cool vids btw gingium keep up the good work
Can you basically build your own rotary engine since it comes apart in sections
Having BRAPS is nice and all, but it is nice to gave Torque. To have raw pulling power.
I love that thicc rotary boi
If you flood pull your fuel pump relay crank the car for 2~3 seconds 3~4 times pop the relay back in and say a prayer should start np
Own an RX8 and it has 123k miles. All I do is the typical rotary car maitenance and to this day the original engine is still going strong
