Rb26 Itb's On Rb25de

[BUCKY01]

has anyone ever swapped the itb's from the gtr motor onto the rb25de?

yeh it has been done before. you need an adaptor plate as it isnt a direct fit. or, people have cut the runners to a short length and had flanges welded onto them that match to fit the manifold and itb's. should do a search there is heaps of topics covering this on both ways to do . .

There are a couple of issues with this. The stud pattern are different from the intake manifold to the head.

There are two or three ways of doing this mate.

1) Use an Adaptor plate - Blitz do this.

2) weld the trumpets on. You have to get this spot on as chaning the runner lengths with affect the performance.

3) Do it the proper way
