will a HKS3037 fit on a STD RB25 manifold??

[Fast31]

hi, looking at getting a 3037 for the RB25 im building. im also welding the wastegate to the standard manifold cause im not getting a manifold made yet. I know it will fit the T3 flange, but will the compressor cover clear the block etc???,

Unless you use a thick spacer plate the compressor housing is going to hit the exhaust manifold. Have to make sure that the HKS 3037 is a T3 flange, majority of them are T25 (I think the external wastegate ones are only T25).

FAST31,

fyi, the standard GT3037 turbo's from HKS come with a GT25 flange which will not suit your factory RB25 exhaust manifold, unless you are getting the GT3037 Pro S which comes with a T03 flange.

I have just finished bolting a 3037 PROS to my skyline and it does require a spacer plate to be made so that the turbo housing clears the manifold. l made the plate about 10mm thick. it was quite a straight forward process just a little bit fiddly when it came to fitting all the the oil and water lines.
