Building a Nissan MR20DD Turbo Engine!
HTML-код
- Опубликовано: 2 окт 2024
- Today we're building a turbocharged MR20DD engine--a relatively new Nissan 4 cylinder engine that has very little aftermarket support. There were a number of design limitations we had to work around but we should be able to double the power of the stock engine pretty easily.
Guess what? We sell parts and MotoIQ merchandise! Now you can buy all the same aftermarket parts we use on our project cars and features from the brands we trust! Buying your aftermarket parts from us is the easiest way you can help help support our channel and make sure we can continue making content like this! Check it out at shopmotoiq.com!

Mike, been reading your stuff since I was a teenager when Sport Compact Car was still out... Read that religiously. Really glad to see you doing the same stuff on RUclips today. Looking at how much work this Sentra engine is to make any power makes me very grateful to grow up with 90's engines. God bless this owners soul for putting this much money into a Sentra.
Guess he is trying to make his own Sentra DET. Since we are most likely not going to get the concept.
This was the engine for the Nissan Sentra DET concept car that was unveiled at the SEMA show., Nissan contracted us to build it.
I love how much love and respect you give both nissan's engineers and each individual engine. You guys make really impressive videos.
You need to talk about the original design intent of the engine.
It's awesome that you guys do this sort of thing.
Props for developing the mr20 it the sr20 grand son hope it has potential
Thx Mike
This adds to all the info I have on my MR16ddt rally car build.
Would love to compare notes on it!!
the plus side of adding port injection as support is that it'll also wash build up off the backs of the intake values and do the engine some good in the long run.
guys, this engine is turbocharged in Europe. It's famously used in the alpine A110 and some Renault products. it's a 1.8 because of smaller bores, but it's the same stroke, so the same crank. A version of it makes 300 hp if remember correctly. you might be able to source injectors and a crank that way, if you ever need it in the future.
I wonder if the MR18DDT has a stronger crank and a main cap girdle like the MR16DDT and if it will interchange with the MR20DD? We only had a few weeks to build this engine and it was difficult to get any parts out of Renault. We had a bunch of stuff on order and it didn't show up.
This video needs more likes!!! Love the in depth precise explanation for every part of the engine. 💪🏽
Mr. Kojima, you’re an absolute legend!
I wanna see you guys max NA builds vs others out there.
There's a couple awesome builds out there that consists of an Atkinson hybrid variant of a motor, and simply swap some high lift cams into it, making 50% power jumps
Or I always wanted to use stand alone engine management and variable cam timing to switch modes at higher throttle openings.
I really enjoy these videos, even though this is not an engine platform I'm interested in working with, I found overall that the information was quite educational.
You guys should do a Ca18Det
That engine was never popular in our market. It was only in the S12 Turbo which there were never many of and none around now.
That’s a shame you would of had some fun with them thanks for the video.
The do tune that engine a lot in australia
Great build! Pumped to see all the custom work! A few things to note: we have built 600 hp MR engines. The cranks can very easily take the power if you keep pressures under control. We rev them out to 9000 rpm (in the smaller mr16 variant) without issue, after converting to port injection. The mr18 head from the versa fits the mr20 block, as they are the same bore and casting. We have done that before. Aux fuel works great, but nothing beats an oem port injection conversion. We have used oem bearings up to the 400 hp area without issue, but there are upgraded bearings on the market. Any MR based transmission will bolt up to this engine. The renault trans he is referring to is the same one that is found in all the b17 sentras and non-rs jukes here in the states. There are upgraded clutches on the market for those as well. We use clutchmasters. The fx350 has handled several hundred dyno pulls at 600 horsepower and quite a few track days for testing. Also; you can destroke the 2l down to a 1.8 by using the mr18 crank. You just have to use a different rod/piston combo. Just like you can stroke up the mr16 by using the mra8 crank.
The open deck will handle 400 whp just fine, again if you keep pressures at a manageable level. Over that, a fill or block guard is recommended.
The MR goat has spoken 🫡
You have a lot of good info on your channel!
@@motoiqwhy are you supporting a child rapist. Fast religion has been charged for rape on 2 14 year old girls. If you support fast religion your guilty of supporting his rape charges as an accident. You don't accidentally rape a child.
"FAST RELIGION WILL BUILD YOU AN ENGINE IN EXCHANGE WITH A 1 NIGHT STAND WITH YOUR DAUGHTER. HE PROMISES NOT TO IMPREGNATE HER, HES JUST ADDICTED TO SLEEPING WITH CHILDREN.
How much to make my 23 sentra quick 🤣
@@motoiq why was my comment deleted. Afraid to get "CaNcElEd" if they find out this dude raped children.
That beautiful 4th gen maxima in background tho!
I had one for 16 years. If I didn't wreck, I would still be driving it.
"I don't think there's too much interest in building these mr's" me currently studying all of this and debating on taking a trip to Canada for the trans and parts 😅
You can use the trans from any 6-speed MR engine on this engine. The Juke and Sentra trans will bolt right up, with appropriate mounts and such. The electronics side is not as simple going from CVT to manual in a street car. We usually tell people to just trade in the CVT car for a manual car, its cheaper and easier.
@@FRArchivedoes the same apply to the mr20de?
Very cool thanks for the information
Good stuff Mike!
I have always wondered how well the Hyundai/KIA Tau V8 would handle modifications and upgrades. They seem decently stout from my research.
Hey mike i swapped an 07 mr20de into my dads 07 versa years ago and have been pondering a turbo since, what a niche/uncanny vid super cool.
I bet that was a neat swap!
@@motoiq it was fun for sure he still daily drives it
This is wild! I'd never expect them to go that hard on efficiency with the stock parts. The rod and piston taper and those pistons in general it's like material is only where it has to be. All about that cafe rating. Those JE Pistons are some trick race pistons! Thanks for this! It's cool to see parts with such different optimizations! I think the 2.5 is even worse for journal overlap. I know it has a dumb low rod/stroke ratio. It's too bad it would be a handful and a half to adapt VR30 fuel components. I think you're on it about all that chamber geometry being for the tumble to swirl ratio. There was an sae article i tried to read about DI optimization but all i took away is that DI and Diesels like one and port likes the other. The new supras have all those chamber hot spots too. It's wild they have squirters in the block and big end of the rod.
What sae papers do you think are worth diving into? Personally Ive enjoyed reading the technical papers from mahle and JE
Man i'm a crash dummy with too many tools. I wondered why the only two DI heads i'd seen the chambers on looked wild and got on google. I think something like "GDI tumble vs swirl" got me to a society of auto engineers article that had too much engineering for me to make real sense of. Having trouble finding it again. Feeling was it's to break up swirl and promote tumble in compression. I could have that all the way wrong though
Yeah and we messed that all up! I bet it makes more power with less boost though. Hope so anyway.
Yessir! The article lumping it in with diesels makes it seem like it's optimization for low rpm cruise where it could use stratified. Very not race car
@@motoiqcan we get a future video on the 4th gen maxima???
If u found this video ur a real car person
im making 280whp on my mr20de
Good video! Really like seeing folks taking a risk to redo modern engines and add that hotrod flair to them. Please update us with complete motor photos, tuning and install dyno results. I have an old 1600 Datsun Roadster that needs a full resto and seeing any Nissan engine build always draws my attention! TY!
We will as a MotoIQ article for sure!
Thanks Mike, super cool behind the scenes :)
I would like to see a D16 build, dohc or vtec
If only Nissan could build a new SE-R😓. Great video!
The SER Sentra was nice.. They did Pulsar VZr and Bluebird sss-z and the Lucino ( sunny coupe) basically a sentra but was not sold in the states or Canada.. with the SR 16 and SR20VE engine they were fun cars my experience was with a 1999 Pulsar VZr with the 20VE swap but after 2002 Renault killed them off 😢
This engine was built for for the Nissan Sentra DET concept car that will be used to study the practicality of a new special edition Sentra.
I've owned a 91 and a 92 B13 SE-R and a 95 B14 SE-R. I had high hopes for the Sentra Nismo but after test driving it I went and bought a Civic SI. I have a special place in my heart for Nissan. @@joebrown9621
Toyota narrows the small end of the rod on the 2.4 Turbo engine that's about to come out
is crazy to hear the sentra only comes with CVT, here in Chile and i imagine in the rest of america the cars come with manual and optional CVT
there are a few guys here in australia running the mr16ddt engine in what we call the nissan pulsar, unopened just bolt ons up to around 300hp, beyond that the dual mass flywheel and clutch become an issue, no one can get them to hold.
I knew this would come to be, considering the Canadian version can be manual.
I just love it when I see a older Nissan that nobody cares about like a Sentra or the g20 p10 with the big wing
That P10 is the hardest car in this garage
Hello Mike. What's the estimated cost of all of that? I have a Rogue Sport, and I might have it manual converted and turbocharged some day. Same MR20DD engine but 6hp less, also fragile CVT (which is the only transmission available in US but not in Canada).
I probably would not bother to build that car.
Sir, you are the teacher we all need in this life.
I would love to hear this thing
Hey are the pistons still for sale
Can this technique impliment into MR20DE?
It should
Hi Mike.
You guys should do a 3.4 SHO V8, since you already have experience with the Duratec V6 it’s based on it should be easier
Tapered small end is used for diesel engines a lot. Which they have less rpm and don’t need the strength in the top as much.
Do you know the reason for it?
Its cause the rod is designed for more compressive loads than tension loads on top of that the piston is also supported across the crown to a greater extent keeping a better sealon the bore and more stability in the ring lands. Its why the piston was able to use such thin rings. Its a very strong piston just not a tough piston due to not having much ductility
@@motoiq The small end taper is because it only needs to carry the relativity light load of the piston as it pulls the piston down which requires less material. The bottom thicker side of the small end is carrying the combustion pressure in compression so it stays thick to carry the much higher load. I seen that on Jays real street performance break down of the new and old supra engines.
@@ther1kid I knew I saw them talked about recently, that was the vid. 4:50. ruclips.net/video/NLcOKNVHoWQ/видео.htmlsi=-yOq3KGUjMA2zI7Z
@@motoiq ruclips.net/video/wINb9Ab3xzY/видео.htmlsi=4Ty-KZ2fwfLyGDvZ talks about forces of the piston. Basically a function of rpm. Less rpm, like diesels, less needed to pull the piston down.
this is rad as hell
That maxima thi
do a 2RZ 3RZ turbo motor build
Check out our Papadakis Racing video.
can i get those piston?????? ....????????
Yes
What had to be done ecu wise for this engine to run
Motec
Wow! So you were part of the Nismo Sentra. Nice! Any hp # you can share?
There will be soon. We talk about the target power in the video.
Haha I asked before I finished the video. 280hp. Very respectable numbers. Very informative video too.
Bro, you sound very very stoned but your words are all gold! Thankyou.
hi Mike, will you guys make a video explaining the advantages and disadvantages that different differential types will give you? im having a hard time finding any information other that “this is how this diff type locks up” and not much about how and when they will lock up and how it will affect different driving styles.. thank you for sharing so much of your knowledge for all types of car enthusiasts to learn from👍
That is a good idea
Sr20ve or vet.....shouldn't be next on the list
I wonder if this engine is compatible with the first gen versa MR18DE, B16 sentra MR20DE. These two engines use the same head and block. 6 speed manual transmission have same bolt pattern, but versa has different final drive ratio. Love your Channel Mike.
The trans we are using comes out of a Canadian Sentra and is Renault based. Wish they offered that here instead of CVT only.
The six speed trans on the versa, sentra, and jukes will bolt right up. They all use the same bolt patterns and clutch set up (minor changes from engine to engine related to clamping force). The mr20dd engine mounts are different than the other mr’s, but mr16 mounts can be modified to fit them. You can mix and match mr heads and blocks so long as the bores are the same. We have a video discussing this on our channel.
You got a cool channel, I wish I knew about it sooner before we did this engine. I am going to spend some time watching there.
I have a question for you, will the MR16DDT main girdle fit on the MR20DD? I know the caps will probably have to be modified but is the bolt spacing, etc going to work?
You have to mill down the main caps, and use the MR16 oil pan/pump, but you can do it, yes. Unless the car is revving up past 8000 rpm or making more than about 300 ft lbs, the non-supported girdle works fine.@@motoiq
Interested in all of these products, when do they start selling?
The engine parts and turbo are available.
@@motoiq hi. how much? would you send to australia too?
👍
Super cool. Adding port injection sounds like a clever way to get around the direct injection limitations. Thank you so much for sharing this detailed information! 👍
Hey Mike , Could you Please make a video on RB26s ? Would Love to hear your Thoughts !!!
We did a simple one, more intensive one coming.
Could you do a build video on Volkswagen VR6? Love to see what kind of power you can get out of the staggered inline six.
I won't be doing it because we don't work on VW's but they are interesting engines.
I wonder if the QR25DE (v2 version in the B16 SpecV) crankshaft would work in the MR block. It’s forged and balanced from factory.
Not even close. The QR and SR20 cranks are close.
Are these motors reliable
Stock, yes
That's crazy! My old Briggs n Stratton 3.5hp engine had a thicker connecting rod
So do some bicycles!
Would this Canadian transmission fit a stock 2015 SR model?
If not what is a good alternative?
Any MR based trans will fit your car. Sentra or juke. The issue is the parts that make the conversion work. It is cheaper to trade the cvt model in for a manual one.
Fingers crossed that the oil pump doesn't blow up in a typical Nissan fashion.
It's a pretty cool pump, more like the one found in the GTR instead of most Nissans
Mike can you disect a toyota UA80E 8 speed from the nee v6 camrys?
No because I would direct any customers to someone like level 10 who has more expertise than we do.
Would you guys ever do one of these videos on an NA/NB miata motor, like a BP4W?
One day, I like the motor.
Probably better to just qr25de swap the car you can buy them for cheap
That's another crappy engine.
when are you doing the sr20ve build
When Martin decides he wants to start.
I mean that's cool... But why. Just k swap it
Because it was for Nissan and their DET concept car so they would not like a Honda engine in it!
@@motoiq ahhhhh yeah that makes sense
Swag
Or you could just buy a car from the 90s that doesnt suck.
would love for my MRA8 to get this treatment. yall are super knowledgeable, could watch videos like this all day!
They already do. We build MR16/A8 hybrids that rev out to 10,000 rpm and make well over 500 horsepower. Reliably.
To expand on this: We have a bone stock MRA8DE making 280 whp. It has been driving around for a few weeks now without issue. We are waiting for warmer weather to try for more power. It should make 300 whp without issue on e85. Then after that, we are just going to see how far we can go until it breaks something.
@@FRArchive very cool to hear! I know the guys across the atlantic run those mr18ddts in the Renaults over 300 no issue but typically don't push the rods over 350. interested to hear how it goes for you
The 1.8 has a higher stroke and compression from what we know, so a few more whp from 12% more displacement makes sense on that. The A8 now has 1000 miles on it, and after doing a comp test the other day, its holding up fine.@@__gr4v1ty__
I wonder why anybody would want to build this engine
A lot of people build the mr engines!
Because they bought the car
What about suspension!
Nismo built by KW
Turbo 2.0 on a Nissan CVT? That's an interesting way to make glitter.
Did you watch the video at all?
@@motoiq yes of course. Canadians got a manual transmission.
I was just thinking how ridiculous it would be to put a turbo on a CTV Sentra. There's only one way that will end lol.
Did you miss the part about using the Renault six speed from a Canadian Sentra Cup Car?
@@motoiqI got about 3/4 through the video so far. I'm having to watch in segments.
@@motoiqis stretching and issues with stock sodium filled valves if you use heavier springs for higher lift cams?
Best 4 banger legendary f20 next please
K20-24
why are you modifying this engine in the first place?
It is in the Nissan Sentra DET concept car that was unveiled at the SEMA show.
why 😮 why what.. why not.!! it's a challenge and to give current Nissan drivers abit of hope of getting some power from the regular every day transport since there is no more GTS , SER or Vzr just the regular eco cars.. people like them but need just abit more oomph and don't want to buy something else.. just a nice unique build 😎
Do any of the parts from the Alpine turbo engine fit on this one?
If we had the time we would investigate it, we only had weeks to build this engine. I am pretty sure that many parts would interchange.
