I just ordered for my sts turbo charged h2 6.0l

Diamond pistons 4.00" bore stock crank stock rods -13.7 dish

ARP bolts for my stock rods

ASP 25% Underdrive Crank Harmonic Balancer Pulley,


am only running 5psi of boost and i really like it

i heared that since the pistons r dished i heared that car will lose hp if i still keep the 5 psi ?

if i ported the heades and keep the 5psi would this be ok ?

i dont wanna change my fuel system its a headech for me . i have walbro gss340 fuel pump

lets see what do u think

port the heads or make it 10psi ?

 

the dished pistons will lower your compression ratio, that along with the forged pistons will allow you to run much more boost safely. If you are going that far into your motor already i would spend the extra $500 to replace the rods as well.

The setup sounds good but only if you want to run more boost, but if you only want 5psi then its a waist of money IMO
