800-900rwhp Turbo build - List your setups here.
#21
Which is why i'm saying for your 100% street car you won't like the 88mm turbo on your 370ci. What's the max boost you want to run and still achieve your 800-900rwhp? What rpm? Those ls9 gaskets with give you the ability to run more boost over those stock mls gaskets you are using. IMO they are worth buying for the price with added insurance if you want to turn the boost up a little more to reach your goal.

What's done to your shortblock? Valvetrain stability and tune will be key...especially at 800-900rwhp and being revved to 7000rpm all the time. Other guys are running stock everything 6.0's but i don't think they are revving them that high with the stock internals. Stangkilr, has a stock 370 with a Turbonetics y2k 91mm making 850+rwhp but I don't think he's spinning it that high either...maybe he'll eventually chime in.

Auto or manual trans with your hp goals? And at 18-20lbs i would go ls9 gaskets and not think twice. If you are wanting that much rpm without the turbo running out of air you should probably go with a 80mm turbo...s480 with the 96mm turbine and t6 1.32ar. My goals are 900-1000rwhp through a th400, built 8.5 Grand National Rearend and spinning it to 7000rpm. BUT, here's what my build looks like...ARP everything (main studs, L19 rod bolts, head studs etc...), doweled main caps, coated everything (main bearings, rod bearings, cam bearings, coated and hardened Trend performance wrist pins, wiseco boost pistons), Akerly and Childs rings, Oliver Billet rods, Stock crank, Morel link-bar lifters and i still need to buy Manton pushrods. I should be able to beat the hell out of it and have no worries.

Comp Cams Lifters
Yella Tera 1.7 non adjustables
Double timing chain
Comp Cams pushrods
Double Springs, Ti Retainers
Block is simply stock crank, Callies H-Beams, Diamond FI Pistons, Topped with TEA TFS 225's 70cc combustion chambers and LS6 intake
I have a built T56, Also i got access to one of my buddies FLT 4l80e with a yank 3600, But i'm leaning towards the t56 since its a street car.

With single turbos (from what i understand, unless you go twins!) you have to make a choice between a smaller turbo for crazy spool and great power in the lower to mid rpm range (best for a street m6 IMO) or go with a bigger turbo, sacrifice the smaller turbo's crazy spool have power come on later in the upper rpm range and carry a lot further than the small turbo (not very practical on a m6 street car IMO)
This is why i chose to go with Comp's billet-ball bearing 80mm turbo. The Comp turbos spool super fast and their billet compressors kick butt too! The problem with Comp is their straight cut turbines causing backpressure issues. This is why i am going with the gt50 style turbine and why killer-ls1 went with a gt55 style turbine. Using these turbines on the Comp turbo seems to have cured the problem. I'm trying to get the best of both worlds with my combo...crazy spool and high rpm power. I'm able to make up the turbo lag with my stalled auto trans...you can't with a manual on the street...on the track you can! Take a look at this thread it will answer a lot of your questions!

But also a $3500 turbo compared to the Borg coming in at $699. Just depends on your budget I guess, but the Borgs he could get into a billet wheel 76 or 78mm turbo with the 87 or 92mm upgraded turbine wheel and probably perform phenomenally even with a M6 for under $1600. Any of those options are 1000 hp potential. I personally have just always liked the Borgs and been impressed by their spool up and performance. Or go with smaller twins and have a nice little combo.

I just sent a PM to INTMD8 to check speed inc kit, If for the long run and street fun a twin kit is they way to go i "MAY" go the twin route, But if i'm sticking with a single Either comp turbo, BW or PT 7675CEA, I'm really leaning toward twins after reading INTMD8's Thread..
Just waiting on his reply.

855rwhp thru the auto, very simple setup...
JY 5.3, gt2-3 cam, head studs, ls9 gaskets, ls6 intake, stock tb, good pushrods/springs...so thats stock heads, stock oil pump, stock rod bolts, etc. Running 24.5lbs of boost to make the 855rwhp on e85, 3 walbro pumps and 80lb injectors(maxed out) This is with the Precision billet 7675 turbo, boost is INSTANT with this setup, on the footbrake I've made 14lbs of boost with the PTC converter.

Numbers in sig with 2005 6.0L mild hand ported stock valve 317's, GT76mm turbo, JFR Isky triple 12 cam. This is a full weight full accessory daily driven 4x4 truck. If you check the et/mph vs weight numbers it's pretty nasty for what it is lol

When I talked to turbonetics and said I wanted 500-600rwhp street, and wanted to do 800-850 rwhp for track they said the 88 turbo. But after talking with a friend of mine that is from the Grand National world from back in the 80's I'm going with Turbonetics HP58 twins. And he is doing twin 62's in his LS2 in a 68 tube chassie big tired camaro for low 9's.
There are really only 2 turbo manufactors out there Garrett and Borg Warner. Turbonetics and Percision are mismatching the housings with the turbines. Turbonetics is Garrett and Percision is BW turbos. But honeywell is coming out with some new type of turbo now also. Think they are still in the testing stages not sure on that though.

Who builds F-Body 4th gen Turbo kit, beside KTYP HURON and Modular Turbo?
I contacted the 3 of them, Huron and modular they dont have any T6 kit and wouldn't do any of them in the mean time too busy.
Any other shops?
