GT Motorsports: 370Z Stock block testing, and turbo system development

1slow370 · 10-09-2009, 08:38 AM

OMG so many theories that are half baked or half explained in one place it should be made a crime. For the people with the differential/sequential turbo setup idea, think fd rx7(one combined cast manifold feeding the exhaust sides of two different sized turbo's with a valve that switched the flow between the two). For cars like ours a divorced bank system works great for packaging, and lets you put the turbos right next to the manifolds for the most flow and heat retention. I would suspect that the stock manifold is MOSTLY separated but retains an inner passage that links the 2 plenums together molded into the plastic. Think balance tube on a VG engine. It is nowhere near what you need to be able to run two dissimilar turbos, which wouldn't work anyway due to the uneven exhaust backpressure. You could brobably get it to work if you did a single kit and used a mazda style turbo setup but those setups are mostly crap and get changed out for single turbo setups because they aren't very good for high horsepower applications. I vote we let GTM do the thinking.

Edit: Surprised no one has thrown out series twin turbos while you're at it geez we could run like 50psi

Also it's called any supercharger that isn't centrifugal(boost ramp) or hey just a bigger motor your looking for postive displacement.

I heard from a little birdy that someone in GA is getting a stage 3 kit with all the extras! I wonder who that could be...

Keep in tune guys for a full build thread with all the details! Major props to the guys over at GTM! Sam alone has made this build possible without him it would still be in the planning stages

by the way GTM has some of the BEST Customer service around!

Neat thread for discussion,, Id like 2X 18 or 20G ish size turbos with 44mm external gates, 1 for each bank of three, moderate size FMIC , spooling by 3300 in third and 3100 in fourth, nice.
What ever comes out I will watch with interest. Should ROCK

Bullitt,

Who's doing your work? I'm also in the ATL area and I wouldn't mind knowing a decent shop when I look to a TT kit for mine.

Oh jesus

Forged Performance is doing my install. They have gotten a new group of guys added to their shop (Scott, Decker, and many others) all of which do amazing work! I cant wait for Scott to get a hold of my car and works his magic for tuning. Scott is very particular about tuning and every car I have seen from him runs perfect! PM me if you have any questions
