Kenne Bell LSX blower in 1st Gen

[streetk14]

90mm TB & new intake to run that TB is not necessary for those hp numbers with boost, so you could save some cash there. If you plan on going over 7#, make sure you replace the head bolts.

The blower manifold is equipped to run a 90mm TB as is, so the only cost would be the throttle body itself. Their dyno charts show it's worth 20 hp on that combination. The stock LS6 throttle body made 525 RWHP with 7 psi, which is why I don't really need the 90mm unit. I have a feeling if I get the cam and heads I want and do the throttle body upgrade I am going to be well exceeding the power levels I have in mind. I have no problem with a very streetable 600 RWHP, but I don't know how much the rods and pistons will like it. When I change the heads I will go with some ARP bolts.
