This is the biggest I could find, but do you know of a bigger one?

p tuning uses v band connections from the turbo to the manifold, so go with the tial stainless housing on a gtx35, as said b4 no need for cams or the 3mm hg, the hg will just blow at some point or another, is e85 available in your area? if not just go pump and be close to 500 and enjoy

 

Take it from me, I blew two 3mm Headgaskets, each time it had less than 1,500 miles on it. GTX35r is overkill if all you want is 500, anything higher than 600 is going yo require you to have a larger fuel setup

 

yea the -8 feed -6 return isnt nessesary for your set up, and def not nessesary on 1 255 walbro, and i agree with joey, the gtx35 is too big for what u want, go with the gtx30

 

Why t4? I thought ptunig did t3 on there manis?

 

my honest advice.. raise that power goal, youll get bored quick I promise lol

 

Is the Ptuning manifold configured so that the runners are paired correctly to support a divided flange? If they're not already positioned that way, they'd basically have to create a whole new manifold design for this. (Which might be a cool idea; I'm just asking.)

The intent of the Ptuning setup is to provide fast spool and plenty of low end & midrange along with healthy top end power. They've already achieved this with a single scroll setup. Why not just buy their kit with a GTX3076R and enjoy it?

 

^agree

 

Well we just won 55hp peak power using the Brian Crower stage 2 turbo cams. Stock cams were AP1. I posted it in the "Turbo cams" thread.

 

dyno comparison?
