Well, it's been a steady progress in work and just want to inform. fellow members of an update on the car. I'm going to paste the links of photos and videos first, cause the list of mods is a bit long.

Videos taken at SRT


Just a point of interest for those dyno experts. I ran 463rwhp & 442 lbs torque at 18psi with a 12:1 A/F ratio. I could have gone for a higher hp peak tuning but opted for the quicker spool and better mid-range performance. I didn't want just a spike at the end of the rpm range just to show more hp. Mo had the car tuned so it will be more streetable and have very good usable power with quick spool and linear power curve on my T-62-1 Turbonetics Turbo. After 30 hard dyno runs, the intake pipe was still cold as a can of beer. With such immediate power, we didn't want to dial the boost up without possible issues with the tranny (stock auto tranny with valve body upgrade) until Mo installs a heavy duty racing tranny. The engine can easily make over 500+whp with race gas and no N2O with the A/F ratio we were getting, but that's another day . On the way home from SRT to NY, I had 4 ppl. in the car (including myself), and at just 8.5psi the car was just pulling like a bat out of hell (the triple clutch t/c helps alot also). Well let's just say, I have a big smile on my face (there was a white Trans Am WS6? who became the first victim of the SRT-IS), and Mo did an excellent job on my car, and was just working (tuning) the car like it was his daily tooth brushing routine :eek: . I'm very happy with the performance aspects of the Stage 4 kit. BTW, what usually takes about 5hours to L.I., NY took me 7 1/2hrs because of traffic, and guess what, my EGT was never over 12 (usually bet 8-10). The car sounds great. The 3" custom exhaust (no cats ) with a Greddy Evo end (muffler & tip only) is not obnoxiously loud at idle to about 3,000rpm, but at full throttle :eek:, yes listen to the vid. clips. I will be changing the Greddy End pc to a Blitz NurSpec 80mm for another 10-15whp gain, cause the Greddy is 2 5/8" or 2 3/4" piping which is restrictive. Enjoy the vids. guys, and I'll try to give you an update with some kill vids . Laters woooooshhhhh.

Richie

No problem dude, just wanted to let you know!!
I'll check back later today.

J.P.

So your at 463 now. Add some more parts your waiting on, tune some more and add your N20, what is your RWHP goal here? Awesome car!!

Wow you only have the stage IV SRT Turbo(2JZ-GTE swap) and you are making 463RWHP(approximately 600hp)! The stage 5 probably makes well over 500RWHP(650hp+++). :eek:

isman

actually Stage 4 is not a swap it's still 2jz-ge. As for whp. I can make more than 500whp with race gas but didn't want to risk the tranny for now. the 463whp was also on 3rd gear instead of 4th 1:1. I had a restrictive end muffler. As soon as I change to 80mm 3.1", I should get another 10-15 whp. Thanks for the compliments everyone.

JAC JZS

I was thinking of the SRT stage 5 turbo which is the 2JZ-GTE swap that makes 500+RWHP... awesome setups(4 & 5) .

ThomsonCharm

You are doing this all with 440 cc injectors? I was just wondering because from my experience you wouldnt be able to go over the rating on the injectors as far as rwhp without screwin something up. Atleast not on pump gas. Or did you run pump gas on the dyno when you did that? Just lettin you know for your injectors this application seems a little extreme and you might want to step up a size.

Later,
