    Yea I would like get a custom just dont want to go huge. I have a set of the early L92 heads and I know there thinner but one problem they said was from stress of high lift cams and stiff springs. Also from reading I need find someone who specializes in L92 heads as the common cams ussually hurt the motors performance. Who would you guys recommend to spec a cam?

    I know being almost 2sec faster then any truck with a rear mount in a truck is over rated.... only had like 5 turbos on mine... couple of fuel systems... and few then a few "stall changes" lol .... sounds like he already has his mind made up on what he wants

    yea I am dead set on rear mount,If you see a swapped colorado you know there is not alot of room. Then throw on top that wanting to keep a/c ps it gets tight in there.

    Listen to casey, i built my rear mount after his and it works great, i daily drive it too on 10lbs. Use stock manifolds (i ported mine quite a bit though) and make sure you keep your y-pipe pipping size down to 2.5" like casey's or your first gear will not be fun lol. Use a dual 2.5" in to a 3" in to the turbo also. I'm running a JGS 400 wastegate with no issues at all. I had my cam for my built 370 speced by patg/eps too although i dont have the motor in the truck yet. Not to sure what casey is running now but i have the exa oil return pump and i bought a back up for long trips lol, its worked pretty well, i tried to buy the weldon return bump but it was back ordered like 4 monthes from weldon. When i started i kept my PS long tube headers and had a 3" into a 3 1/2" y pipe (not recomended by casey lol but im stuborn!) and it didn't work out to well lol.
