lg8 turbo

[magicturtle]

Hello everyone

Im new to the forum, but definately not to gettin my hands a little greasy.

So...i need boost

Heres what im workin with, and my build plan:

Gen III 3100 w/aluminum heads
Basic mods so far.

Ive got this in the works:
Full P&P on intake manifold and cylinder heads(doing this myself, have a fully equipped shop in my back yard)
1.6:1 alum rockers
ARI cam, lift is 420 intake and 443 exhaust
OS stainless steel valves..not sure what i want to run here yet...
59mm MMS TB

WOT forged pistons...20 over, coated and yielding a 9.5 comp ratio
WOT Forged H beam con rods...
Megasquirt for tuning

4T65e w/HD upgraded diff..

Now, what i want to know...
What should i do for fuel, ignition.. valve size..
I plan on getting a custom turbo manifold and running a t3 .60/.63 eventually..
Only lookin to boost about 9-11lbs..

My goal is 330whp.

Any tips, info, opinions..would be greatly appreciated.

Money is not an issue for me, ive been blessed with a good job and i have virtually no expenses..

Yall lemme know!

I would go with a WOT tech roller cam not the flat tappet you mentioned. Besides the flat tappet cam has less lift than a stock 3100 roller cam unless the specs you posted are with 1.5 rockers. get the matching springs and all from WOT tech too. WOT sells a turbo camshaft too. emails will have them get you everything you need one stop shopping.

also a t3 turbo is way too small to make 400 hp. you re going to need a t4 compressor wheel to make that. precision has a 5431 for under $800 bucks. that will spool quick on a 3100

to make 400 crank I say 42 lb injectors should work and bump the fuel pressure. stock ignition is fine and so is stock valve sizes.

are you using 3100 heads or the gen 2 heads? if gen 2 then you can buy these already ported and save yourself some time.
