Rb25 Heads

[25GTV]

Do all rb25 heads including na use the same ports and bolt pattern for the intake and exhaust manifolds? Could i get a r32 rb25de head and put my r34 neo manifolds etc on it???

yes all the 25 head have identical intake patterns and ex patterns. yes the neo manifolds will fit same.

No.

Please know what you're talking about before you post.

The R32 RB25DE head has the same intake bolt pattern as the RB20DET. R33 RB25DET intake manifolds and R34 RB25DET Neo intake manifolds DO NOT BOLT UP.

Exhaust side, RB20/25/25neo are all the same.

To the OP, why would you want to get an R32 RB25DE head and put your Neo manifolds on there? if you're looking to build a 25/30 then you're better off sticking with the Neo head if you already have it
