Ok so I have a turbo Ls and im thinking of replacing the pr4 head for a p75 and a mani. and well im looking at the blox and the performer x manifolds and im not sure which would be good for my set-up. Its a stock LS outfitted with a t3to4e 57 trim and I dont wanna rev past the stock redline, so im just not to sure which way to go.


oh and my tb i plan to send out to maxbore.....thanks

See my thread I just posted in the off topic forum........Shows stock IM vs Skunk2.....

Thanks man, i've seen your setup on honda-tech and its sick!
well im kinda leaning towards the blox for the price but I was just worried about the low end torque the stock mani gives, and I see your dyno that its minimal or what do you think?

If you wanna keep the stock redline you might wanna think about keeping the stock intake. I am running the Crower turbo cams so that might make a difference too. I take mine all the way to 8K though.

But since I have a stock bottom end maybe ill just rev to 72-7800 if it still making power offcourse, so you dont think the blox will be better than stock overall and my intercooler pipe is 2.5" and thats also why i wanted to upgrade.

Performer X is an All motor manifold Victor X is a turbo manifold. Or so I was led to believe. I have a Victor X on mine Turbo LS and it made a noticeable difference in the power range on my last LS turbo.
