STS Turbo in Camaro SS at Exotic Performance Plus

Will do! Thanks for the compliments! Bob

I have this kit as well, had it for over a year. Koolaid, I'm not sure why your pump is that loud, but mine isn't nearly that loud. I can hear it when I'm starting the car (it's hooked up to the same lead as the fuel pump), but past that I don't even notice it. As Bob is doing this buid up, I am in the middle of a 370 iron block, that will hopefully see 15-18 psi from a GT70. The car should be a beast. :firedevil

That is good news. It would be normal to be audible on startup, as the pump starts at high speed (it has 2) but then shifts down to the lower speed as the engine warms up. I will be investigating this winter to see what is going on. Mine also starts even louder, then shifts down to a muted roar as it warms up.
I have the GT67, and I am pleased at the power at 8 p.s.i. non-intercooled.
A 370 with 15 psi would be quite interesting.

You're running 8 psi with no FMIC? Are you running meth? I just found out that I need to go with the GT76 instead of the GT70. I'm a little concerned with the lag on such a big turbo, but maybe that'll help with traction??

No, I went with larger injectors and a custom (not mail-order) tune. Also remember, there is a (slight) intercooling effect from the long intake tube. It runs very well, no knock, and exhaust temps are right in line. When I was doing all the work, this was the recommendation from STS, either meth or larger injectors.
Not sure what effect the larger turbo will have on lag. I went with the 67 because they said the stock was not really good enough for 8+ psi. Perhaps that is why they told you to go larger, because of the boost you want to run?
Not sure about your traction issues. Mine is the 1-2 shift. At that point, the turbo is spooled and I'm on the pipe. So, lag would not be in play at this point, since the turbo is already spooled.

Friend of mine sells the STS kit, put 1 on his truck and gets full boost by 3000RPM.

I know a guy that has the STS on his Escalade EXT and he thought the exhaust was too loud so he had an exhaust shop put a Borla muffler on it. It sounds sweet. Don't know how much power it made though because of the all wheel drive and the non-availability of a 4 wheel dyno.

We will be getting a video of this car. Thanks! Bob

**GatorSS** · 10-10-2005, 03:51 PM

Is there a kit for the new H3 Hummer?

**02IKND** · 10-10-2005, 04:52 PM

I put a STS kit on my stock 02 WS6. I've been very happy with it. Just because the turbo is in the back does NOT mean there is turbo lag. I just recently had her dynoed. Here's my dyno sheet on, remember this, a completely stock LS1 with only a STS turbo for my mods. The first two runs were at 4 psi and the last run was at 7 psi. 467 hp with 508 torque. My air/fuel is totally of whack so next is getting it tuned...again. I'm working on an intercooler, bolt ons, and headers. Maybe even methenol injection.

Since it won't let me post the pic you'll have to cut and paste. If it doesn't work, let me know.

Wow, this kit has been out for over a year and some of have never heard of it?

Bob, what FMIC is on the front of that car? I'm looking to get one for my STS.

Well 02IKND

I am impressed with those numbers.

I have a 02 ls1 and allready bought Head, cams and headders for my car, but not put them on yet. Your setup would be something I will look more into.

A ? for ya, did you do the install yourself and how many hours did you spend.

N/M just read that it came from TRT. TRT's FMIC looks pretty good.

Thanks! My car is completely stock except for the suspension and the stuff I did with the turbo. Yes we put it on ourselves. A friend and I put it on. We did the turbo, fuel injectors, fuel pump, and computer. It took us a day and a half but with a few less beers and less goofing off, it would have taken less than a day. We just had too much fun playing around.

The intercooler kit is from Texas Rear Turbos. You might check into the one made by Synergy, as it looks to fit better. Bob

We're taking this car to Norwalk this Saturday the 22nd. Hope to see you there. Bob

**Exotic Performance Plus** · 10-22-2005, 07:44 PM

Norwalk looked like it was going to get rained out, so we went to US 131.

This car is one really impresses us! We took Scotts SS to US 131 in Michigan. With the boost on the low 6lb to 7lb setting, and 14 psi of tire pressure in the M/T Drag Radials, this car was severely traction plagued!
This car would of been in the 10's with a couple more passes.
We were going to run more runs and up the boost, but they kicked us off the track for not having a cage! Bob

**jmangler** · 10-25-2005, 04:24 PM

Nice to see that after everyone doubting the STS proof is on the slip that these kits do pritty well! Let us know how you make out on your next trip!

**Exotic Performance Plus** · 10-26-2005, 02:54 AM

Will do indeed. Thanks! Bob

i have a few questions no one has brought up yet about this. how well is the turbo going to handle the water if its driven on a rainy day? i'm sure its going to run cooler than a traditional trubo (up to 1600*F) but it still has to run pretty darn hot, if it gets hit with some cold water isnt' there some concern with warping? i'm sure if it was a gradual rain that slowly picked up the water would not be much of an issue but what about running though a puddle and splashing it? it seems to me like that would be the biggest problem with it.

also those pics can be a little decieving, exactly how low in relation to the rear end does the turbo sit? looks to me like a speed bump might cause some pretty serious problems.

also exactly how does the oil system work? does it tap into the oil pan or use its own self contained oil system with a cooler and filter and all the other good stuff?(that sounds a lot more reliable and less likely to have any contaminates that can and do kill turbos to me)
