i have got a A31 cross member- dont think R32 are the same- engine will sit higher

I did RB20 into my S13 and got an a31 crossmember I was also told it will make it sit lower, but recently had an a31 and R32 next to each other and couldn't tell the difference.

This was without the engine mounts installed, just the crossmember by itself.

A31 and R32 Crossmembers are the same..

I have done many RB Conversions and yes, the R32 and A31 ones are the same...

You will want a RB25 Engine Crossmember to make it sit lower.

I believe it is the late model ones that do it, but it could be all of them.

ive done bout 15 rb into silvia conversions and yeah 32 and a31 r the same the best to use is r33 that way u can use r33 power steer lines and rack and everything lines up and loks neat. and the fact that engine mounts r sitting flat which makes engine easier to get in
