370 LQ9 Build - Need some guidance Im planning an LQ9 370 turbo build and need some input. The setup is going in an M6 98 Camaro for street/strip with a goal of 700+ rwp. I would like to run mild boost on the street for use with 93 and 15+ with race fuel.
LQ9 370 (Complete with harness from junkyard)
317 heads - hand ported/polished
Stock crank
ARP studs/bolts throughout
Truck manifolds with custom tubing - Intercooled
Car 98 M6
8 pt cage in process
Sub-frame connectors
Moser 9 35 spline axes Full Spool 4:11s
Pan hard bar Torque arm Anti Roll
Outlined below is what I need some input on:
Turbo
- What size and model?
o BOV - Tial what size?
o Waste gate Tial/JGS what size?
What rods/pistons/rings should I go with?
- Lunati/Eagle/Compstar/Other? I Beam or H Beam?
- Wiseco/Arias/Diamond/Other? What CC for good CR with 317s?
- Rings GFX/Total Seal?
Valve Springs
- Brian Tooley .660 lift platinum w/ titanium retainers or ??
- Would you use the stock valves?
Cam What do you recommend? I want something pretty wicked...
Head Gasket Cometic or LS9
Intake If I use a stock style intake, what would you recommend? I would ultimately like to find a good deal on a FAST intake. Also need to figure out what fuel rail/injectors (Siemens Deka 80 lb?) to use.
Fuel
- Car currently has a Racetronix pump (I think 255), but I need to figure out what size it is. I doubt it will provide enough fuel
I appreciate any feedback!

Personally id get some hbeam rods and some forged pistons with some good rings like hellfire or something.
I use cometic head gaskets on mine, and stock intake as there seems to be minimal gains for aftermarket price per hp.
I gotta big nasty chopping cam but can tell you from experience it helps allot with spool to use a proper turbo cam, but I like a nasty lope lol
Comp pushrods , and definitely get a bigger pump or two 255's
Im a fan of ebay turbo parts , but im sure there is more power in the name brand pricey stuff.
Best of luck man
