I got a question for the STS Turbo owners out there...

I wanna get one for my car, and was planning on running a 7psi boost on my stock engine with the mods listed....

Will i need to upgrade my injectors? i know i will need a computer tune. that is a given, if only for the fact that i need to raise my rev limiter and remove my speed limiter.

Also, will my engine be able to handle it for a while? at least until i get it rebuilt specifically designed to handle the increased power and RPM's.
Can my stock rearend and tranny handle the extra power?

Any help would be appreciated...

 

at 5 psi you may be OK, but any higher you'll be fine if you get the METH kit, otherwise no.

 

You will need to upgrade your fuel system to run 7 or 8 to be safe. You also will need either the meth/alky injection or a FMIC. If you have long tubes, you will have to get the LS1 kit to clear them. With a good tune, your engine should do fine for a very long time, unless you are constantly ******* the hell out of it.

 

Oop, almost forgot a very important thing....

will the kit clear my SLP X-Frame SFC's? ????????? i kinda have em welded on.

 

nope... they gotta come off.

or the drivers side does anyway...

 

I believe the LT1's keep their SFC's. Check the pics out on STS's site. LS1 drivers side SFC has to come off if you already have one on there.

 

From the horses mouth. This is the email I got when I asked that same question about my LT1 car.

James, you pretty much need to change out the left side sub-frame connector with ours. It is designed structurally to work as a sub-frame connector in place of what you have and you will definitely get more power out of it. If you want to give me a call some time I would be glad to answer any questions or anything else. Thanks. Dave.

Either David is confused or they changed how they are making them. Here is a picture from STS's site showing the install on an LT1. See how the intake tubing comes back towar the middle of the car away from the SFC.

The LS1 kits have the pipe that runs in the sfc channel along the drivers side.
The LT1 ktis run up the center. If you have an LT1 with long tubes, you have to use the LS1 kit to clear the long tubes.

 

WOO HOO!! Awesome. that means i ain't gotta chop it off WOO!

Hey trtturbo, what sorta prices you guys got on the best turbo setup for the LT1's? i wanna get the best one, that way when i rebuild my engine i won't have to spend more money to get the better setup. i plan on just running my stock engine with the 5psi, and then when i rebuild and tune it, then run higher psi. Thanks

 

The best LT1 turbo kit, or the best STS kit?

 

I am getting an STS Turbo kit either way. i don't want none of those "cramp up the engine bay even more than it already it is" kits. I want the best of the STS turbo

Besides...trtturbo only sells STS kits. that's why i asked him.

 

I dont think you do unless you have Long tubes. Your sig says edelbrock shorties, so they should tuck up fine with their y-pipe.

 

how do the sts kits avoid lag? only thing i can think of is they use smaller diameter tubing for the pressure pipel, but that would restrict flow...
so can anyone explain?

 

They dont avoid it really. It's been shown already that they spool head units very similarly to a 3.0 liter supra motor, on a V8 5.7 liter F body.
