Intake Plenum

Post by 82m » Fri May 04, 2018 7:25 am

Has anyone ever tried putting the lower intake plenum from a z31 onto the z32?

Or know any reasons why it could not work? I realise the heads are different but how different?

Cheers

Hi Mate

I'm one of the few on here with a Modified Z31

The Difference in the lower intake manifolds is quite different so they wont bolt up, In theory it could be done with a thick enough adapter plate

I have been working in with DJZ on here to design a better performing plenum for a Z31.

There is quite a lot of Z31 Plenum Idea's on Z31performance.com and also the Z31online facebook groups. For something really nice its going to be a fabrication required type deal.

A lot of People use a Nissan Terrano v6 Plenum as a core to build an RB/ Supra style tapered plenum.

I am running an early vg30det inlet manifold a lot larger inlet ports but you can port match the inlets to match the inlet runners easy enough.
