Basically it spools the same if not better than the BW8374 Pitlane raved about....it will flow allot more mid/peak though displaying a more efficient turbocharger.

So I had Autotech Engineering install a precision 6235 turbo today along with valve springs to my FG XR6T and the results have been great.

Top end performance is night and day difference and just doesnt stop pulling all the way to the cut out! Bottom end is good but not quite as good as the small FG turbo for that instant kick on boost.

Anyway here is a before and after graph of the small turbo tune from earlier in the year and the new 6235 tune running about 17psi boost for reliability, Spiro said he would lean on it harder with an E85 tune that I may get done next year sometime.

Mod list is,

PW stage 2 intercooler

PW race box and battery relocate

Xforce 4" dump and 3.5" exhaust

Wastegate and flapper mod with Turbosmart actuator

1000cc injectors and fuel pump (460 walbro is it?)

Autotech Engineering valve springs

I do have one question....does anyone make a .82 rear bolt on internal wastegate exhaust housing for these cars??

A smaller housing with the bigger turbo would make for a weapon of street car!

Cant wait to see the new Garrett GTW line turbo's become available, the GTW38 is a 950hp rated turbo and should almost be a complete bolt on upgrade.

Its not a race car...if it is then so is mine.

Mine will see 500kms a week with a cage etc along with raced with old school wheels ;)....= race car :P

Try not having a agenda Matt its fun also.

I know Bretts dads car went near 139mph from 21psi displaying a supreme turbo...has another 5psi yet up its sleeve.
