SRT 2nd Generation Twin Turbo GS400
I Finally got my car back from SRT for an upgrade to my Twin Turbo setup, and as promised I am posting pics of the upgrades. Basically, the design of the manifolds/intakes for the TT setup were re-designed so I went ahead and purchased the upgrade to the 2nd gen TT setup. I also got a custom exhaust system that replaced the restrictive stock exhaust system. I replaced the borlas (which are for sale CHEAP) which I previous had on the vehicle. I loved my borlas but this was a performance upgrade to help with spooling the turbos faster. I got a return fuel system, bigger injectors, upgraded fuel pump, TWO Blitz blow-off valves, and a rebuilt stronger transmission to handle the extra rwhp. Also since SRT has an in-house electronics specialist, I decided to replace my Pioneer AVH-P7300/TV tuner/8000 brain (also on sale) with the new AVH-P7500 touch screen unit, since driving my woman's 2002 ES300 with Navi, I got spoiled with the touchscreen! lol The AVH-P7500 is an AMAZING unit! I'll do a review in the electronics section since I also looked at the Clarion, Alpine, and Sony units too.
I am breaking in the tranny so I haven't dynoed for new numbers so I am only at around 9 psi, but I should hopefully get it tuned for 14psi on Sat. The car spools a lot quicker, and the power is almost instant. From the "butt dyno", I definitely feel an increase in power. Too bad there is snow on the ground here! Anyway, to the pics...
Enjoy!

Show me your engine bay, man!!!!!! 
We've been wondering where you disappeared to! I saw you every now and then in supraforums.com but I never see you around here anymore.
I am curious to see what your 9psi or even 14psi can hold up against my 18psi 2JZ-GTE. You would probably lay my a$$ on a platter and hand it to me, eh???
See you on the flipside.

Side View.
My last dyno at 11psi with stock exhaust was around 445 rwhp, at 9psi the car feels alot stronger with the upgrades than at 11psi. I will be at 14psi after tuning on Sat.
jtanoyo1 - where are you at now in terms of HP?
