I would look into RPM transmissions for your trans issues.They are one of the vendors here and I am certain that you will find them HIGHLY recommended for your build of the transmission .
I thought that I would start a topic here to share pics/info on our upcoming AWD SS build. I recently aquired a '06 black AWD SS, and I will be tooling around with developing a single turbo setup, addressing the transmission issues, and updating the fuel system. I own a small shop in Southeast Louisiana, and we specialize in custom/production turbo systems for odd-ball, late model vehicles.
I'm not looking to really advertise a "kit", per say.. Right now, I'm only interested in gathering/sharing info for this build on my personal vehicle. If I do decide to offer a kit down the road, I'll look into advertisement and such on this site. With that being said.. please limit your questions to general knowledge. (no sales questions please).
Here's my plan so far..
316L schedule 10 stainless tubular turbo headers
316L 14 gauge 2.5" stainless y-pipe and flex section
Single Precision PT67/GT-Q trim with undivided .81 A/R T4 exhaust housing, and .70 A/R T04S comp. cover
3" stainless down pipe with flex section
3" stainless turbo-back exhaust with converter
60lb Mototron injectors
Twin Walbro 255lph pumps with CNC'd custom stainless basket/sump
Twin -6 AN stainless feed lines from tank to engine bay
Billet aluminum fuel rails
Our proprietary front mount air to air intercooler with 2.5" and 3" custom aluminum piping
Tial 44mm wastegate
Greddy Type R BOV (recirculated)
I'm figuring 6-7psi with meth injection on 93 octane will be in the 425awhp range on the stock bottom end. The truck will be tuned using SCT's new GM software. I'm going to pull the engine this upcoming summer for a mild build to handle 6-700chp.. but, I want to see what the stock engine will handle, safely.. I've got a pretty good bit of knowledge when it comes to this sort of thing.. We built the first (and only, to my knowledge) turbo setup for the inline 6 TB motor, 2 years ago. It is making just north of 400rwhp on a bone stock motor, with a Raptor built 4L60E, and TB SS rear end installed. It is tuned with EFI Live software..
Cool pic, showing the intercooler setup, and how we incorporated it behind the factory crash bar.
As far as the trans is concerned.. I'd like some input from some experienced members. I've been told to look into Phoenix Transmissions for a build to hold up to the power levels that I'm looking for. I do plan to tow a 5000lb boat, still.. so I need to keep the converter mild enough to perform that function.
This will be a long, drawn out project (3-4 months). I want to really get this thing out in the real world and do some testing on the stock engine to see what is really feasible/reliable. Your input/questions would be greatly appreciated..
