If i go with the sts turbo, LT headers, cam and exhaust how much power will i be pushing to the wheels? Would it be worth it for me to go with the sts turbo? I only want around 400-450 HP with a good tune off course. It's either that or LT4 hot cam kit. what would you guys go with?

 

I actaully have the STS kit on my 94 z28. It's defently a awesome kit. It pulls very hard. I'm made 400rwhp on a mustang dyno on a stock lt1 engine with a lt4 hotcam @7psi. It was defently worth the money. - Mike

 

IMO I don't like the STS system. I say either make it a cammin' jammin motor, or save the extra $ and put a real turbo on it.

 

You have both LT4 hot cam kit and STS ?

 

i have the STS kit too on 5lbs and its awesome. i decided to pump it up a lil and spun a rod bearing but that was my fault. even with 4.11s it pulled hard and got full boost around 3300. the kit was easy to install only took 1 full day. only bad part is the pipe that connects the subframe pipe to the over rear end pipe hangs down a lil low but i know a way to fix that. also the filter being in the back you kinda gotta watch where you are driving dont wanna suck up water. recomment the snorkel kit from the GTO.

 

Well you see. Before the STS kit I had the lt4 hotcam put in. Then about 2 years down the road decided to go with the STS kit. It works great with the STS kit. Cause I have both the cam and turbo kicking on at around 3k rpm. But yeah it's defently a awesome kit. Car never sees rain or snow so I could not tell you how the turbo performs in those weather conditions. But other then that it pulls very hard. Just waiting for the new shortblock to to turn the boost up

 

Have you got it dynoed?
I wanted the exact same thing like you have. LT4 hot cam kit ad then add the STS turbo, but my friend told me that your car will be too much to handle.

 

Yeah I had my car dyno tuned on a mustang dyno. Put down
377/378@5psi low boost and high boost 400/408@7psi with Meth injec. That was on a stock lt1 engine with the lt4 hot cam. I run the car on the streets all the time with no problems. Very dependable and the best part is when you want all the power just hit the pedal. Cause the car will drive normal untill you floor it. I walked on allot of supercharged cars already. Just do your research on the set-up that you want. I almost based my decision on other members thoughts such as [CALL911] who said STS systems are junk. Honestly since I had the sts system it has been the best thing I did to the car. It makes awesome power and I would defently do it all over again if I had the chance.

 

sts is like having nitrous ready but don't need to refill the bottle ever. So it ain't sound to bad at all. Full power come on at only WOT. And of course front mount turbo will always be better but some thing gotta gave. Rear mount turbo will be faster and made more power than any head cam combo.

Mine is not a STS kit but a custom built rear mount turbo with 383ci LT1 T6 turbo 85mm, during testing few yrs ago, at 18psi on 4th gear tires busting loose at 80mph. Now you show me where a big cam jamming combo can do that. THERE NONE..... Turbo Turbo, regardless where it is mounted, it always be a power on demand..

 

Awesome guys...Thanks for all your comments. I'm going to get the LT4 hot cam kit and then add STS turbo to it.

 

If you're putting a cam in it anyway go with a custom cam or a turbo grind. Just about any cam is going to be better for a turbo car than the Hot Cam.

True. Even thow I'm running the lt4 hot cam with my set-up. Theres better cams out there that will make more power. I just happen to have the cam installed years before I even had the turbocharger. My forged shortblock that I'm currently building up I'm going with a custom grind turbo cam. The specs are 224/230 .581/.588 115. But either way the hot cam will still work great if you decide to go with it -Like I mentioned I had no problems with it . Mike

 

i put down 398rwhp on a supper hot day with 5psi but i also had alot of computer tuning. im sure on a cool day it could have made a lil more.

 

Was that on a stock engine or the 383 you have in your sig?

 

stock LT1 the 383 will make around 550-600 on around 8-10lbs and if it dont il kill chad golen lol no hes a good guy
