Car: Stock Block LS1

Goal: 600 HP capacity- Wanting to make 500rwhp @9psi

Setup: Twin Turbos, IC will be Air/Air - either a large front mount to two stock supra cores. Fuel is already taken care of.


An online calculator points to me needing a Garrett T3 .63 A/R turbine housing.


I'm thinking a T3/T4 would work well, but i'm getting confused by wheel size, trim, etc. I'd like something easy and reliable, not costing a fortune.

I found a place that has a T3/T4 .63 Turbine with a T04E 57-Trim compressor, which sounds close, but please inform me.

Thanks,

Mike

 

Twin T3/T4 setup will get you there... even a twin T3 setup or a sinlgle 60mm would do 500 rwhp.

 

Original plan was for a single, but i honestly think the twin setup will be eaiser.

Thanks for the input

 

If you're working with a 4th gen, the "packaging" makes doing a single setup a lot easier (IMO). Although you add the crossover pipe in the single turbo setup, you don't have the extra turbo, oil lines, intake ducting, filter, exhaust plumbing, wastegate plumbing/vacuum lines. In fact, even with all the room in the world, I'd think that the single was more straight foward/easy... although I know a lot of people will tell you otherwise. I think the main reason people go the twin route is the cost of the turbos - you can get twin T3 or t4/t3 turbos for $100 to $200 each, with wastegates built into the exhaust housing. A single t-60 will be $600 used, or more, and will probably need an extrenal wastegate ($200+).

 

Thanks for the help.


If anyone could reccommend a good place to get these turbos, feel free to chime in.

Ya for a 4th gen, with ur guys small little engine compartments, I think the packaging for a single would be best. I think if you factor in cost of a single turbo vs twin turbo setup the single would win out cause though the turbos may be cheaper in the twin setup, you also have to factori in two of everything basically.

But to each his own.

Those three are really great places, talk to their tech guys, they know their stuff soooo well.

Ease I have to go with the single turbo route unless you are willing to move some stuff then it is about the same.

Places to get a turbo..
Innovative turbo or Limit Engineering.

Limit Engineering
Innovative turbo

I had my turbos built by John Craig at Limit Engineering and have gotten things from Innovative and have been extreimily happy with both choices. I would personally get on the phone and start to talk with both shops and see what you need and what they recomend for your setup. For a total goal of 600 hp I would take a look at a t-66 through t-70 should suit your goals very well and spool up will be very nice.

Definitely agree that John Craig and Innovative are absolutely _GREAT_ to work with. Both places know there stuff, and the service is awsome. John Craig came through for me in a pinch when my turbo's compressor wheel ate it, and innovate has some great products that are priced very well.
