R34 Rb20 Crankshaft In R32 Rb20det?

[noksin garage sweden]

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.
