T-RAV99 GMC | 5.3 | Skinny White Guy Tuned
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 wantsNOT this guy....he's has no idea what hes doing with turbos or tuning them...
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.

Yea everywhere reading alot are saying go small on piping to the turbo. Also what return pumps you guys running I seen these about a year ago and price didnt look bad but it sucks I am with you that I will prob buy 2 for long trips to be safe.

Forgot to post link ???
I have used the tilton/mocal then two others .. Finally got the turbo worx pumps .. 330 bux well spent ! ... There are tons of tricks I have and can help u with going to a rear mount .. And pics to share .. What intercooler do u plan to run ?? You have my number ... Use it .. Or text me and I will reply with some pics !! I had stock un ported manifolds on my 408 but yes there is alot to gain with some arm work !! Now ported and coated .. The converter is very important also !!! Tune .. U can keep it very mild an easy to drive .. Mine was only in the 230s and able to make 745@ 13.7psi. On it's best day .. The downfall for you will be the cam and valve springs ...
Well actually got the truck up on stands,got under it and got dirty and did some measuring and had a wake up. Lookin at you guys pics there a good bit of room,under mine well..... its still a mid size truck. I am sure I came up with where it will be mounted needs a little bed mount triming and exhaust will exit in front the pass tire. I talked to Casey which was very helpful In getting some loose ends I didnt understand and nicely telling me I need to ballz up and put a lil cam and converter in it.
quick picture of my setup.
