Best Inlet Manifold/plenum For Rb20/rb25 Non Vct Head

[R32 4 Door]

Hi Guys,

Just wondering what other people have been using on their cars? I am doing an RB25/30 engine using the R32 RB25 NON VCT Head. I have been told that the inlet manifold/plenum is not interchangeable between R32/R33 versions of the RB25. Due to hight issues under the bonnet of the S13, I would like to use a greedy style forward facing plenum, can this be adapted to the R32 head?

Thanks, Chris.

No, the Greddy plenum for 25t can't be modified to fit, if you have a search you'll find a pic that someone posted up a few days ago of an RB20 inlet manifold gasket sitting on a 25t head.. nothing lines up!

I picked my plenum up on Friday.. runners didn't line up properly but with the stock runners being a fair bit larger and thicker than the GTR side, things actually lined up reasonably well on the inside.. just looks crap on the outside
