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.

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!

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.

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

this was my thread http://www.bimmerforums.com/forum/showthread.php?1796461-E30-r25det

also another RB converted E30 this was litterally the only one i was able to find and i can get you in contact with the guy who built it hes a good dude and happy to answer questions http://newman.onyxsyndicate.com/e30gtr/e30gtr_00.html

Sorry another one of the build threads looks like i updated this one abit more tho http://www.stanceworks.com/forums/showthread.php?t=35540

Edited by rcs_888

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.

    • Haha I do that.. thats when it chirps..The bit point for me is almost non-existent. Otherwise I stall it. But yes, in terms of performance, the clutch is solid af.
    • Greg speaks wisdom. These dirty old Datsuns are only value when they are cheap. When they are not cheap, there is no value. Sounds contradictory, but it's true. We are now 20 years past the hey day of modifying cheap 90s JDM cars for small amounts of money. This is a different world. If you are rich and can afford not to care about what is effectively wasting money on an old Datto shitter, then I have no reason to argue against it. But if you are wanting to experience what we all experienced back in 2005 (and I bought my car last century!) then there is no way to do it.
    • Short answer: No. Medium answer: No, because you still need to conjure the things out of thin air to bolt them to a NA to make it a NA+T. Long Answer: No - The things you need to conjure - meaning a turbo, intercooling, manifolds, exhaust, intake/manifold/piping, clutch, injectors, fuel pump, AFM (?), ECU + Wiring (woo, N/A loom fun) have to come from somewhere. You could have many scavenged these things from an OEM car that someone had upgraded from and use some of these. This will be cost prohibitive now, especially so in the USA. You'd probably pay the same for newer, upgraded components that are better than old OEM stuff from 25-30 years ago. None of these big ticket items are re-usable for the N/A car. Why not buy new and upgrade while you're there? The only real consideration is turbo and fuel sizing and determining whether you want to stay within the bounds of the OEM engine or get into rebuild territory. These limits ARE lower with a N/A motor and especially N/A gearbox at the starting point. And if you're gonna upgrade those then you may as well consider having them built to begin with. Because everyone here knows you're never far from that next engine rebuild once you start making the power you want... The cars you see on the internet and SAU etc have been built over decades. If you're really clued in... you would sell your US car to somebody for what you paid for it. You would then scour AU JDM pages or SAU and buy a car like Dose's on this forum with your powerful American Dollar. This will save you so much money in the long term. Importing it could be tricky. Or it might not because USA. I have long said the only reason 90's Japanese stuff took off was because a) Japanese people had Japanese cars so that is what they used b) Australians could import these cars to Australia with very minimal changes and use them on the road here c) Neither country had well-priced access to US or EU Sports Cars. I don't believe the JDM scene would have taken off in Australia at all if we had EU priced EU BMW M offerings, or more especially the AUS V8 Scene would never have existed if we had the multitude of US cars like Camaros, Mustangs, Corvettes at the prices you folks do. After all - Do the math. I would say put a V8 in your R34 and that's the smart way forward. It is. I did it. I know this from my own experience. But at that point there's no reason to simply not buy a C5 or C6? It would be simpler and easier and cheaper and bette-
    • Reading all this... hurts lol. I have an ENR34 5MT and I paid an inflated USA price for the car alone, had to do tons of preventative maintenance past that, and so I'm over $30K USD into the car already and haven't even touched power.  I wanted to +t it. Not even trying to make GTR numbers, I'd be happy with 250hp.  Can I get away with paying much less to make that happen?
    • Damn you’ve done well, definitely snapping necks.
