basic sts turbo kit

**1991ls13** · 04-07-2011, 07:36 PM

Im sure there`s been some talk about the sts rear mount on here and what not. And im considering doing it for a few reasons but i have a few specific questions for my application.

i have ls6 prc stg 2.5 heads with a tv2,bolt ons like long tube headers etc.

If i was to get this how would my car act? Would i need another cam? etc?

Plus what turbo comes with it? It says app specific???
i seen a gto video dyno`d huge numbers, but it was on a 67 trim which im sure doesnt come with it:[ame]http://www.youtube.com/watch?v=8oARLy37Qkw[/ame]

On a different note real quick, i have a ls6 and with this cam its nice as my dd but is a bitch for the first 5-10 mins of driving. If i was to stroke it to a 383, what size cam would it act like compared to a 346?( if you get what im saying) and what cam would act most like my cam now, in a 383?

thank you very much.

As far as the sts kit on that Gto, it's sts piping with a different turbo if I'm not mistaken. That's actually my friend Rich's car. He runs Hoods Performance and is a dealer for sts. I'll have him hop on the forums when I see him (should be Saturday since he is having his annual cookout lol) and have him give you some more info about sts

I have have the GT 67 turbo intercooled kit waiting to be put on my Camaro. It did come with 42 lb injectors but i did not get any specifications on them. Can you ask him if he has any data on the injectors they send out with the kit?
Thanks

ya cause i have 42`s already and i could save a bit already having it most likely.

He said if y'all have any questions about it, shoot him a call on his cell and he would be more than happy to help answer your questions. He can also give you more info about his car.

42-lb injectors seem awful small for a cam/heads car with a turbo on top of that.

Have you calculated your injector size needed based on your estimated HP?

**1991ls13** · 04-11-2011, 11:16 AM

right now i have them and to be honest, its plenty if not too much for how much im putting out now, but yes, i think it will be pushing it if i turbo it

i would swap out for 60's i just maxd my 42s at 473rwhp,530fttq

**Johnstonj2005** · 04-11-2011, 05:50 PM

The Gto in the video at the top has 60's in it.

That was kind of my point. Most FI applications, even with mild boost, use around 60-lb injectors from what I've seen.

You don't want to really go over 80% duty cycle.
