Rb20 Flywheel On And Rb25 - Please Help

[vitz_n1]

hi all,

Just wanna know if i can use an rb20 flywheel on an rb25?

I know the rb25 has a locating dowel which is what stops me from fitting it.

I am trying to fit the flywheel off a turbo silver top rb20 onto a turbo rb25 just to have everything crystal clear.

Now i have searched and found about 400 topics on this but nothing 100% clear.

Can i or can i not drill the rb20 flywheel to fit? OR can i or can i not cut the locating dowel off the rb25?

Any help is appreciated.

Cheers

they are the same flywheel, you can even use an RB30E flywheel on there. clutches are all the same size also. Im also 99.9% sure that a r32 GTR flywheel will also fit.

no need to redrill

This may not always be true.

When I upgraded my clutch and lightened flywheel in my 32GTST my mechanic said that the new lightened flywheel could not be used with the old clutch. IIRC, the new flywheel diameter was larger. Luckily I had the upgraded clutch ready to go in and all was sweet.

I don't know if I have a different gearbox under the car or something??????

yeah i have an RB25 flywheel but the my clutch doesn't fit, it only fits on my RB20 flywheel....

i spoke with jim berry from race clutch and he said that you can just drill through. I just wanna know if anyone has done it to be sure.
