Pathfinder plenum piping for turbo Z31 w/ AC ... updated

[bemis]

Here's what I got so far. 2.5" piping from the turbocharger to the TB. Yes, 2.5", because I plan to upgrade the turbo later. I am running 2.5" piping leading from the MAS to the turbocharger underneath the motor mount.
Now I have to find somewhere else to mount the boost sensor, but that is the least of my problems. The valve covers are getting powdercoated "red", the same color as the valve covers on the 450SX being built at EllisAutoWorkZ.












I have noticed a little more turbo lag, but its still nothing worth mentioning about. I do however notice more torque, and even more so around the higher RPM ranges, where the stock plenum starts to choke the engine. Now I have to dig into the ECCS and retune it a little bit to take more advantage of this plenum.

Oh ya, I'm still waiting on my powdercoated vavle covers, so right now I have a borrowed set. :evil:

Very cool. Do you plan to eventually use an intercooler assembly or stick with meth injection? It would be interesting to see just how much power you can make with an upgraded turbo, the meth injection and no IC.

Keep up the good work.

The turbo inlet tube looks nice too. How many cut/welds was it? Would you like me to add it to the custom turbo inlet page in the turbo FAQ?

Intercoolers are not on the list as of right now. I want to just stick with the methanol injection just to see what it can do alone, without an intercooler.

The turbo inlet piping is actually made of a bunch straight pipe cut at 10 degress on each side. ( I ran out of bends) so it is alot of cutting and welding. I will post some better pictures of everything when all the welds are cleaned up (I'm welding with a stick welder ) and the pipes are painted. You can use those for the turbo FAQ.

Are you eventually goin to take out the a/c?

If he lives in Florida, and went through the trouble of finding a pathfinder tensioner bracket to fit the pathy plenum, and making the piping clear the compressor... I don't think so.

My Z has fit 5 ladies and myself, ask me how I know. It's the pimp wagon!

It should also be noticed that using the Pathfinder a/c bracket to lower the a/c compressor would also give more clearance for intercooler piping leading over the top of the a/c compressor to the stock plenum.
