Making my own setup. Pte Gt42-76 1.12 a/r. Journal bearing, ls1 will have no problems spooling, dont care what i make hp wise, i will run the car around 500hp, probbaly 7-8 psi for this yr. Once i build the motor and get a trans i will max out stock ecu @ 14.7 psi, which should put me high 600's to low 700's. Standalone maybe hit 8-9 but this is all a while away, and ill probably have a bigger turbo when i go standalone.

+1 on not needing a standalone BTW. You can make more than 1 bar on the stock pcm, just need the right map sensors and a SD tune. What options are you after that the stock pcm doesn't offer?
. My car maxes out @ 14.7 psi guys.

Your car a 6 speed? It might be more laggy than you anticipate. I had a T76gts on my M6 back in the day, but with a .96ar ex housing and it made 10 psi by ~3700. Figure your 1.12 housing will slow it down a tad. You won't notice ANY lag if you have a decently stalled RMVB auto.

If i have lag it will act as a good traction control.
Im 99% sure im going to do a rmvb TH400. But i need to get turbo done, then 9 inch, then auto, then motor.

B/W S480 with race cover. Truck manifold kit built by me. Hp...whatever it takes to run 8.9X at 3100 lb raceweight (around 1050 flywheel). Car will be used to anger neighbors and frighten small children. Possibly will try and play in the pump gas drags next year.

Bought APS twin kit last fall. Didn't install yet was waiting on engine getting a 408 ordered up in next few days. APS had great introductory price and wanted twin turbo ,it comes with huge intercooler, nice piping and tial wastegates. Year or so ago ordered a turbo kit from GMR speed. They had partnership war,shut down and lost 2000 bucks. So from now on only order from big long time established companies. GMR was sponsor on this site and was around for a fair amount of time.
APS shipped their kit early and quality looks great. APS cars are already doing good times and dyno numbers..search this forum. My hp goal is to have 850rwhp off spray and maybe 1000rwhp with direct port small shot. Likely run around 700rwhp on street most of the time.
Other ting I liked about the APS kit is that it keeps factory air conditioning ,you don't even have to move alt or anything and it looks like plug access is really good also.
Some guys keep saying the turbos are too small but its already done 10.21 at 137mph on a 402. At low boost.Thats plenty fast enough for me. Also smaller turbos will spool quicker than larger ones in general. Turbos are also mits 20gs tweaked up and these type of turbos can be rebuilt. I don't think garett ball bearing turbos like have in my talons can be rebuilt. Garett are pretty reliable though.
