Need some help on turbo build ls1 ls6 heads Have:
a 7875 turbo from turbonetics.
CX racing A2A intercooler setup
CX racing exhaust manifold, wrapped.
Sent in some ls6 243 heads to Advanced induction to have them polished/ported with upgraded valvetrain (was planning on doing an N/A setup but changed my mind as most of us do lol). Ended up having them machine me a custom ls9 cam. Same specs as the ls9 but with higher lift (.600,.600). Also had them send me a ported ls6 oil pump. Going to upgrade the trans (m6) through tick. Stage 2 with a viper mainshaft. have a ford 9 inch that needs abs integrated into it. Going to run a holley dominator fuel pump.
Planning on running 14 psi on stock bottom end.
My goal is around 700-750hp on pump gas with hopefully decent mpg/drivability
My questions are: if I do get pistons, which ones are the best for the money as well as rods? Do I Need to upgrade the crank?(If I do, what differences safeties am I putting in place?) How will the how can I integrate the abs into the rear end as its an older ford 9? Do I Need to upgrade the ls1 timing chain? What gears should I put in the rear?(yes I know the 12 bolt is better but can't afford one lol. got the 9inch for free). Should I supercool the air into the intake manifold to get a better density per square inch in each cylinder?(If I do that, how much boost and what kit?) How will the ls9 cam with that lift be on driveability/performance/overlap?

bump and help from martin @ Tick Performance with the cam. I sent him a couple emails and haven't heard back yet. Reading his recent posts with Denmah, looks like I should be looking at a 224/226 cam with a 114LSA and a .600/.600 lift instead of the ls9 with the .600/.600 lift.
Come on guys, just needin a little help here.

I would wait for martins email, he always replies back.. He probably get 20-30 emails a day on camshafts!
I went with the speed inc tu1 cam 225/225 .571/.571 113+1
It's an XER lobe cam so my valvetrain has to be on point!
Upgrade to a new ls2 timing chain, trunion rocker upgrade, 3.50 gears is a perfect gear for a turbo car.
However if you want to get complicated you would find out the power band of the cam you choose, then decide where you would like to shift @
Then use a gear calculator and plug in some info when you want to cross the 1/4" mile mark (rpm) then it will ask tire size etc... Then it will say optimal gear ratio (this is just one example to choose gears)
I'm running diamond pistons, basically any 2618 aluminum piston will work for the power level you want. Stock crank is good to 800-1000 hp depending on driving style, pick a good 6.125 rod (eagle h' here)
