welcome bro!

Sounds like a cool project.

Im thinking your gonna need at least 72# Injectors.

But how much boost you planning on ?

i have a 408 w/ a pt88 a1000 92# injectors and i ran outta fuel pump and injector on 8#'s, you need a pro series pump capable of 1600-2000 hp for forced induction and you would also need to consider ID1600's for injectors and a minimum of 10 an fuel line.....So with that said you looking at around 2500$ for a awesome fuel system package and you motor will never go lean :]

Forced Induction on E-85 takes quite a bit of fuel. Get a power goal in mind, do a little reading, talk to some fuel system companies, ask more questions then build to suit.

I just went mid 10's @ 5000' elv in my 4x4 reg cab 4875lbs with a camed lq4, and T78 on E85. That was with 60~ 68lb injectors, 2x255's, and 1 m15 meth nozzle. Injectors were at 98%. 80lb injectors, meth and a Pt76 would have no problem getting a guy low 10's at sealevel. The pt88 makes killer power but not worth the lag in my opinion unless you are going to push it to 18+psi and 1000+ hp. A good pt76, S475T4 or Gt76T4 will all make killer power and spool great. The GT76T4 is a easy 9sec turbo on a good combo.

There you go^^^ . Copy this build and im sure you will be more than happy!

The stock bottom end in these motors have been proven up to 800 hp with proper tuning.

I just saw you are down in Fountian! I'm up on the NE side of COS. You will hate PT88 up here in this elevation on that low of boost. It spools about 4~4200RPM vs the Tc76 @3200.
