Hi there!

We are currently trying to rebuild a 1993 Nissan Skyline r32 gtst rb20det engine.

The crankshaft is to badly damaged for repairs so we are looking for a replacement, finding parts for rb20 in sweden is hopeless, but I have found a r34 GT rb20 crankshaft.

Is it possible to use a r34 2.0 GT rb20 crankshaft in a r32 gtst rb20det?

The partnumbers does not match according to nissan fast but maybe it will work anyways?

Please enlighten me!

Vey best regards from sweden

mate, the R34 will have a RB25NEO motor in it, meaning its a 2.5l crank.

There was a Non-turbo 2.0L RB20DE Neo released for the R34.

This car was not allowed to be imported to Australia.

Hi!

Can you measure rod journal diameter on your RB20DET crank?

One of local A31 cefiro users tried to do exactly same thing - use neo RB20 crank in his cefiro 20DET. Turned out rod journal diameter on 20 neo is 42mm - similar to RB20E. RB20DE/DET off earlier Cefiros/Laurels/Skylines has larger diameter rod journal - 44 or 45mm, main bearing journals are the same.

Maybe you can use neo crank and rods, I don't know if stroke and rod length is the same.

Also I may be able to help you with used crank off an earlier gen RB20, as I am quite a bit closer to you then the majority of forum members here. Send me a PM.

Regards, Petros.

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
