bought a 76gts, but what about a pt88?
I bought a 76gts today from Jose to go with my 365 ls2 Hiflo. Getting rid of my gt42, just wondering what you guys think. After talking to Jose he convinced me it would be a better choice for a 6spd street car, it would give me better throttle response than a pt88,since its not a drag car, Iam more interested in handling and making 700rwhp on pump gas. what do you guys think?

ls2 block, stock crank.
Iam just afraid to get it and not be enough.I see MM and other guys are running pt88, but Ill be driving the car thru canyons, halfway thru a turn and the boost kicks in. Jose said the power delivery would be better for a non-drag car.
do you guys think Ill make about 750rwhp with this on pump gas?

Sorry I don't have much else to add to the thread. I have no personal turbo experience.(unless its a diesel)

Dude you are going to love it!!
I have only put together 2 gears about 4 times but wow.... First geat is useless, as is second for me right now... I have held it spinning through second, and as soon as I shift to 3rd it's up right away, same thing with 4th gear. MPH stacks up QUICKLY. I'm at about 13.5psi with mine now, working my way up
I have to go out of town tomorrow AM and will be gone for 8 longs days away from the car I'm glad when sl03h03 bought the kit that he sold me, he had the 76GTS, and I'm glad that SuperDaveZ (think I have that nick right) picked it out in the beginning to sell to Ken H. (sl03h03) ....but yeah, it's the f'n best thing ever

I agree a 76mm turbo will be fun with no if any lag on that 365....... but im not sure about 750rwhp on Pump gas...... only one way to find out........

works for me ..... im making 750rwhp no problem with it on my 366. 15psi. cars not even dynotuned yet. still low 10s AFR. hope u got some decent heads tho
the 76gts on my setup seems to be outperforming the setups with 88s making 100+ more hp.

On a 346ci, these are approx. numbers since all setups are different.... This is based on 8.5cr, and 270cfm heads with a LS6 cam. 6spd trans as well.
S76 - ~3900
S78 - ~3950
S80 - ~4000
S82 - ~4100
S85 - ~4300
S88 - ~4400
The S80 is by far the best all around for big power and good spool up.

I agree with Jose on this one. I spoke with he and Jason about this setup yesterday. I believe he was telling you 88 for more of a drag race setup and 76 if your roadracing. He said its crucial for you to have quick boost response coming out of an apex and tail end throttle control, which I would have to agree. If your racing on curves you need quick response since some of the steering is done with your right foot. Also he didn't tell you the TC76 since its not as powerful and the GTS is going to be the better unit to reach your power goal #'s, and still keep the setup responsive. The TC76 I would would say is a nice 650-700rwhp turbo on pump with 750 on pump out of a 76GTS being more likely. On race fuel, both will make stupid power. Also I personally wouldn't run 750rwhp on pump gas, to much can go wrong one time and boom, another new piston or headgasket is needed.
