Rb26 Powered E30 M3

[SSM]

I'm new to the forum and to the RB26 engine. I'm a car enthusiast from Norway, and my main passion is with BMW. I belong to the Gran Turismo generation and have fancy the Skyline since playing Gran Turismo on Play Station. The RB26 have a beautyful sound that I just have been dreaming of having. I bought myself a BMW M3 seven years ago, it then had the stock 4 cylinder engine. In 2010 I swaped it for a S50B32, a 3.2l E36M3 engine with 321hp/350nm. This summer that one did not want to play my game anymore, so I pulled it and sold it. My plan was to go even newer M3 engine, from the E46M3. As time passed by there was also a LOT other E30's in Norway going the same route. So I needed a new plan.

And as lightning from clear sky I got the idea of the RB26. My car is LHD just to make things more complicated, but hey, it is a hobby and I got time. I sourced a R32 GTR engine with 115000km. I bought it from a shop and they fixed me a R33 GTS gearbox and push type clutch.

As I mentioned, I have not any experience with the RB26. So that is one of the reasons I'm making this thread here, so you can come with input and I can ask here instead of making 30 new threads.

I have been reading a lot about the RB the last weeks, and have gotten some basic info.

Anyway, here is some pictures.

Removed the diff and the AC pump

This is pretty much how the engine will sit

In order to get the engine as far back as possible, I had to cut some of the oilpan.

Not much room for twins here, so single it is!

The RB is not as high as a BMW engine, so this sits low in the egnine bay. Very nice!

Need to modify a bit here around the heater pipes. Hope I can cut some out of the rockercover to make more room.

The gearbox hole need to be modded as well. Probably cut out an use the dogleg shifter that people use when swapin the RB25 gearbox in the 200sx.

Thanks!

I don't have any more updates. Doing some planning on how to do things.

I have bought a plug and play wiring harness from Wiring Specialists in USA, so there will be no eletcial issues on the engine side at least. It was shitty expencive. This build is going to be road legal and approved, so there is coming a guy from the road unit to inspect the car before I go on with the build.

I'm looking at the Precision 5454E turbo, is that a good choice? The turbo needs to be equal spec to the stock twins in order to get it road legal with a single, so I can't go big on the turbo. Aim is 4-450 crank HP as i mentioned.

Here is some pictures of how the car looked in this super short season I had this year.

Got this bad boy in the rear axle!

I have ordered a set of these wheels, they are ETA in Norway in the start of December. Should make a nice chrismas present for myself, even though I payed them in July!

[XKLABA]

Are you running single 5454 or twins, a single 5454 will be to small, I don't think it is any bigger then just one of the factory twins

[SSM]

Single 5454 yes. I don't know, so I'm open for input. But in order to get it approved it needs to be equal to the stock twins. The 5454 is rated to 495hp

[Redline_GTR]

Very nice mate.

Will be interested to see how this goes

[GH05T]

keen to see more

[XKLABA]

I would look more at around a PT5858 which should make about the same power v boost but have better responsive depending on rear housing, hopefully one of the turbo experts can confirm this though

Is going to look awesome with the work wheels on it

Nice build subscribed!

[SSM]

The suspension I'm running is Intrax Racing 1k2 ARC Black Titan, cost just under 5000euro

The 3.2l engine that I had

I'm using Motorsport Hardware bullet nose studs with extended race nuts

Brakes is updated to E36M3 all over. Running Performance Friction discs front and Performance Friction 11 Compound pads round, with PFC brake fluid and Goodridge steel braided hoses.

Interior is Recaro Pole Position ABE and carbon fiber

All the best with this build mate, I'll be watching it closely for sure. I love M3s and RB motors. Your combining the two, enough said

Got recommended to use a BorgWarner EFR turbo that is internally wastegated, this give me more room to play.

But I have difficult on deciding on a manifold. Anyone that have a opinon? Full-Race and RAW is above limits.

Both T4 twin scroll and T3 open scroll is alternative, but not with wastegate ports.

[AMR33]

6boost

[Hadouken]

Wow that Jun baffle looks awesome

SUBD I started an E30 RB build ages ago but ended up getting stiffed on motor and gearbox paid good money for a good running engine and gearbox and turned out 1 piston had a hole in it and gearbox had 2 gears missing and just a heap of other stuff went wrong so unfortunatley abandoned it. ill see if i can find my old thread buddy might be able to see some of my mistakes lol

Thanks. Yes, I have read that thread before. There is a LOT of solutoins there that you will not find in my car I have also read all about Newman's car, and there again I find a lot of bad solutions and shortcuts. Like taking the exhaust through the heater hatch....

Anyway, these bad boys turned up at the door today. Will take som better shots when I'm going home from work.
