This setup was just put together before the show and only street tuned. And that was straight turbo no nos. He did not want to squeeze on a motor that had not been properly tuned on the dyno. So to me 400hp untuned is damn good.
Clean looking Z but definitely needs a lot of tuning. those L-series motors really come into their own between 6000 and 8000 RPM and it was breaking up around what sounded like 5000.
I agree with the EFI crowd here. either a triple turbo weber like the devil Z, either a proper throttle body. 700+hp pre-mount turbo IL6 aint no good, will get detonations and worse...nice potential, indeed.
The potential for this setup is there, just get the kinks out and it should consistently run 500s to the wheels. 600+ to the wheels with shot, so yeah that means 700+hp car. Stay blessed.
I am wondering how many of the individuals commenting have made 400 or even 300 rwh with an L series. Years ago Raver Motorsports built a 3.0 liter L series for me that put down over 500 rwh with a stock CT26 turbo and a large shot of nitrous on 110 oct. this was with SDS injection 420cc injectors and a properly set up wet shot. I can say that N20 is VERY unforgiving of lean mixtures under boost and I hope that whoever is tuning the carb and nitrous has the skill set to do it safely.
"Builder must be disappointed with those numbers" Really? Why? A _healthy_ l28 with stock compression and a stock head will have an engine running about 160-180 hp off of the boost. Factor for drivetrain loss, and we should expect to see about 130-140hp hitting the rear wheels. Start adding the boost and we start adding in the power. Boost is just an atmosphere multiplier, and engines are just air pumps. Pump more air, make more power. Obviously things like heat soak and other factors bring us diminishing returns, but for the most part- if you run an extra atmosphere of boost (1bar/14.7 psi at sea level) through an engine, you typically double the horse power. So looking back at our numbers, if we ran 1 bar through our little engine putting 130'ish to 140'ish hp down to the wheels, wed expect to double that power, and make 260-280ish whp. Now if we go to places like hybridz, where theres a very strong community of people who own and modify these cars, we can start cross referencing these numbers to see if were in line. And for the most part, we are. Youll find a plethora of people running about 15-20 pounds on junkyard stock engines making high 200s to low 300s. Upon request im glad to go dig up numerous references supporting this assertion- I myself rebuilt an l28et to factory specs, did some bolt ons, and am making about 300 whp @ 17 psi- So i too also fall right into this range. Now lets jump back to this gentlemans engine. Hes running a 3.0 vs the standard 2.8, or about 10% more displacement, lets give him a _perfect_ 10% increase in base line power, obviously it would be less than this as nothing is perfect, but hey- lets go with that. So well assume hes making "about" 150 base whp. We also know, at least according to him as the dyno doesnt show this, that hes running about 20 pounds of boost. 20 divide by 14.7, we find weve got a atmosphere multiplier value of 1.36. (150x1.136)+150 gets us 354. 354 is well under the 400 hp he put down. Now of course this doesnt factor in things like compression ratio, nor cylinder head. Is he running stock compression? Higher compression? Lower compression? Id wager stock or lower, consider the amount of boost he wants to run, and the fact that he intends to run a 150 shot of nitrous- Which would lower his base line hp factor a bit, but lets just assume hes running a stock c/r. That leaves us around 50 hp to make up by the cylinder head. if he made all of that up by the cylinder head, thatd be _about_ a 15% increase in air flow to bring us up to 400 hp. Through a non cross flow head, thatd be a pretty reasonable gain for some simple head work (Ie something like an Msa stage 1 or 2 cam, one of the most easily obtainable cams for these engines). So ya, im thinking 400 hp for a carbureted l30 that hasnt been broken in and is only roughly tuned, doesnt sound too bad. His peak torque was a bit low, but that can easily be chopped up to the tune or the specific jets hes running. Add his nitrous in and were looking at about 550 whp, breaking it in and dialing in that tune could easy bring him very close to that 600 whp he was hoping for. Thats a pretty damn quick little toy. Imo anyways. But thats just my point of view. Id love to hear yours :)
Responsible Costanza "Before the Dyno testing he said he was looking for 6-700. He got about half of that you autist." lol Yes. Yes he did. He also said hed be upping the boost. Hell need to up it more than he talked about to push 700, but he wont have to touch it much to hit 600 (if at all once the engine is tuned properly. weve no idea what kind of afrs he was seeing, nor what his ignition was doing- But the engine was audibly breaking up). But I wont hold it against him if he was being rather casual in a casual discussion about his car.
Responsible Costanza no need to be disappointed, 400HP in a car as light as a 240z is plenty fast. 6-700 HP would just be stupid in my opinion. He should fix the rust before going for more power in my opinion.
Ah just realized after watching it only bad 400hp but your aiming for 6. You will need a TON of work in that head, and port out the intake and exhaust manifold. Ill be curious what your going with the trans to hold that torque once you get up there with HP.
I don't think it will make 700hp....well maybe for just one run with a ton of nos. A nice build but I would think it can make 450hp tuned with an efi system but not having a crossflow head is a big problem.
So sick interesting carb setup why not convert to fuel injection though way more acurate. Regardless that is a sick build, looks like you swaped the 280zx turbo motor in aka l28det.
+Brian Heiden because carbs are for men who aren't afraid to get their hands dirty. Its a pity the chicken shit tuners can't go for a spin without a laptop.
howard100ify No carbs equals more power plain and simple, you might try the intelligent aproach, more power is for real men ace! Carbs are for simple minded people that cant tune.
Pull though carburetors are inferior to blow though, when combining turbo's and carburetor fuel delivery, on something like this, I wonder why the owner went that route... All that money he seriously should have just stuck a small block in it.
That thing is going to be so hard to get dialed in stand-alone Standalone Standalone you need it.... if you want to sell that engine let me know I'll put it on my stand alone I'm running a stock l28 on 30 lb of boost
+shutthehellup6666 A very slang term. When I hear NOS I think of Fast and Furious. Or Nitrous Oxide Systems products. I do not think of the two stage nitrous system I own.
A carb on a nissan L?? No your motor needs. A look of fuel And air carb is resticting the 2 of them And the p47 is mechanical butt does not foat in hi rpm= more control and more stable it has pros and cons but thas a real z car And u have muscle no tu put
damn all that stuff and only 305hp. No wonder everyone just throws ls1 and calls it a day. I would rather go with a 5.0 mustang engine for a few hundred bucks and make same power or more.
+Jonathan Cabanas I dyno'd 300 hp with 13 pounds of boost and am now at 400 hp at 20 lbs and the motor is bone stock except ARP head studs and aftermarket fuel management. The motor can handle more and I still have less in it than I would an ls1. With 255 street tires in the rear on an 80 degree day it will spin the tires at even at 70 mph
Old video , I know, but it keeps popping up ,the car must be sold by now. I would have saved ,all the Polish and gleam for a more focused known technology,this 1. Looks wrong,too many bends and turns and elbows.Way to much polished ,silly money spent.2. this car can be a very fun car to enjoy both in corners and straight line with 200hp. 3. This new fad of reaching 700 to 1000hp ,4 miles per gallon, is just plain stupid, on a street car ,just stupid.( Well a vintage one that is)
This thing can make 600 easy. The engine is not stable at all. with it tuned properly the numbers should go way up. Carbs are a bitch !!! People are just getting used to seeing cars pull crazy numbers on the first dyno run. Fuel injection even at its worst is still miles ahead of a carburetor.
I like my l28 stroker but it doesnt have the kind of power that I really want. Im eventually just going to swap it for the RB30det but that is in the distant future.
+shutthehellup6666 Yeah I made 300hp at 13psi on my stock l28et with aftermarket fuel injection probably at about 400 now with 20psi if he would ditch that carb and 150 shot 550 hp should be doable.

That car begs for an EFI system
+Andrew Moore seriously i was shocked to see a carb!
@@Jamesashleycoyle . Especially with a nitrous system. I prefer carbs though
Amazingly beautiful! I wish I could get my 88-Z to 401 hp! Man that's nice....
Except for the side mirrors, this is a nice looking Z.
Clean looking Z but definitely needs a lot of tuning. those L-series motors really come into their own between 6000 and 8000 RPM and it was breaking up around what sounded like 5000.
old school with a dash of high tech thrown in for good measure
Good job Robert!!! :-)
Looking forward to seeing it go for those 9.20's

SidewaysGts I bet his water injection was messing things up. If I was him I would tune on 93 then add the water injection after that is figured out.
It looks like the car is trying to jump off the dyno. Its like "I wanna run Freeeeeee!!!"
port and polished.
Why pressure the motor through dyno pulls without a tune? Very interesting build though. Any updates?
needs to get those small rust spots taken care of
Don't let it idle at low rpm for too long or the fuel will puddle in the intake manifold just after the turbo. ;-)
the head is the limiting factor. Would be lucky to hit anything over 500hp.
Ah just realized after watching it only bad 400hp but your aiming for 6. You will need a TON of work in that head, and port out the intake and exhaust manifold. Ill be curious what your going with the trans to hold that torque once you get up there with HP.

Please What Name the Music ???
What exhaust manifold?
if is it for sale please let me know
Can a L28et block handle 700 hp?
probably not.
it can... just dont go carb if you arent gonna set it up right.
what transmission do you have holding up to that motor?
how much would all this cost?
where da at doe
What carb was he using?
Good Goin bro

The original L28E and L28ET motors have electronic fuel injection so I have no idea why hes gone backwards with this.
Point Blank Thats what I was thinking lol.

EXACTLY!!!!!!!!!!!!!!
Epic
whats the name of that engine anyone?
L28e converted to carburetor and turbo
to bad he didn't spend as much time on the body
There is no way that has another 300hp left on the table...
It is nitrous
@@IcejjfishTbone I stand corrected. 😂
Spend some money on getting the rust fixed, fancy engine bay does not go with a rusty body.
Respect lost with the carb..
That's an up in respect for me
Your dreaming if you think your running a 9 second quarter lol. You need more power man.
That thing is going to be so hard to get dialed in stand-alone Standalone Standalone you need it.... if you want to sell that engine let me know I'll put it on my stand alone I'm running a stock l28 on 30 lb of boost
Did he really say NOS....
+SC457A nitrous oxide N20.......or slang term NOS
+shutthehellup6666 A very slang term. When I hear NOS I think of Fast and Furious. Or Nitrous Oxide Systems products. I do not think of the two stage nitrous system I own.
+SC457A We all had to learn through reading so don't act like you knew from the moment you were born.
I had my nitrous kit on my car since 1992, we used the term spray most of the time.
NOS is just a brand of nitrous, it's like how we call ear cleaners Q-Tips
I saw this car try to run pro but epically failed he ran 14.00 in the quater mile he doesn't know what he's talking about
+howard100ify haha thanks brother I'm just speaking the truth
