View Full Version : turbo budget

I have a revhard manifold.
What would i have to do to it to run a 300zx turbo? what is the stock boost on one of those and can i adjust it with a controler?

also, if i were to get a junkyard IC, could a machine shop do any necessary repairs and upgrades? Can i powdercoat a IC?

if you paint the i/c it will hurt performance, as paint does not have as good thermal transfer than the i/c metal

A 300ZX turbo should fit on the manifold, as its a T3. However, you may have problems fitting it in the *car* -- I'm not sure if the T3 will fit without hitting other stuff.

Stock boost on a 300ZX is around 6 psi I believe, and you can adjust it higher with a boost controller.

A 300ZX (Z32, T25) twin turbo turbo, or a Z31 (T-03)turbo??

Z31 should work, as Asad has previously stated. You can "clock" this turbo so it will not interfere with other components in the (engine)bay.

you can clock this turbo, if you're running an external wastegate.

I'm using the integral wastegate, but have no fitment problems since I'm using a OEM style manifold that turns the turbo in the OEM orientation for single turbo nissans.

do you guys know what id have to do to the manifold to make a Z31 turbo fit(internal wastegate)?
I think rextreme has modified his manifold, but im not sure EXACTLY what to tella a machine shop to do.

the problem is that you're not getting a central entry turbine housing. OEM turbos (most turbos) have the inlet offset like a "snail shell". This makes fitment a problem. He welded a flange to "angle" the mounting position so that it fits.

Yep.... You have two choices. You can have the flange on the manifold itself ground down so the turbo sits more "level" or you can do what I did. I tried to do the first one because I though it would be easier but it turns out that the machine shop I took it to wanted like 200 bucks to do that job. So, I came up with the new idea. I bought the flange at a local speed shop for $20 bucks. Then I had a friend down the street bend some round steel stock to fill the gap and weld everything up nice like. Here are the pictures.

Yeah... Yeah....
