Default SO, im going turbo and know nothing about it, come inside

Well after i ran 11.08 at 119 Stock Internal i decided to take it to the next level...im going turbo, so far i have a brand new GM ls2 block and a bunch of money saved heres the basic plan (PLEASE give pointers)

MOTOR

ls2 block, stock stroke forged, forged rotating assembly
317 heads ported from TSP (10:1 compression)
ls6 or ls2 intake
reversed truck manifolds
precision turbo (have NO ****** clue how big to go)
twin in tank walbro setup
93 octain with a water/meth kit

Transmission
FULLY BUILT to the max 60E, it has literally everything they make billit input/output shafts, 5 pinion planetarys, an aftermarket input drum that holds more clutches and has a brace to keep third gear from burning out, its also sleeved...and a bunch of other ****, selling the ss4000 and probably going with a custom spec'ed converter from like FTI or yank

also have a brand new 12 bolt in the car with full suspension, and its a light *** car...

I wanna make around 700 without trying, and keep it there but i also want to be able to go up you know....700 outta run some mid/low 9s i think considering i went 11.0 with 324 to the tire

The motor sounds good to me. Callies Rods and Wiseco or Diamond Pistons with the Stock Crank should suffice.

Go with the LS6 Intake Manifold, the LS2 is that pressed polymer crap and can come apart under boost.

A GT88 from Jose at FI would be nice. Or if you must go Precision the PT88. If you JUST want 700HP and no more the PT7675.

Save your money on building a th400 tranny or 4l80 for the power you want IMHO..

And when you do twin walbros, uprgrade your fuel line to -8an atleast, to support 700+

How fast do you want to go?

T4 or T6 flange?

Sell that 60 and get either a 4L80 or a TH400. Whatever it is needs a brake.

I would save the money on the forged crank if your staying stock stroke and use the extra $$$ on a thicker deck head (AFR, Trick Flow, ECT ) People here have made 1,000 + HP on stock cranks.

317 heads have been too 1000rwhp, get a 4l80e pt88 or a pt76 would be perfect and stock crank
