Yep, all fabbed up by me. I will be doing everything except the tuning. This is my daily driver ,so I will be building the kit a little bit at a time then taking it back off the truck until final install. This is my first turbo build, so any advice is welcome.
It's a 76mm, .96ar exhaust, .80ar comp side. T4 flange.
I'm shooting for 400rwhp for now until I get my built engine and trans in, then I would like to hit 550rw.
The engine is stock. Current mods are: longtubes (getting replaced with shortys or manifolds), roush catback, cat less y pipe, underdrive pulleys, electric fans, and Frpp hot rod cams.
I'm not sure what size hotside to run. Would dual 2.5" merged into a single 2.5" under the truck and ran back to the front be okay? I'm not sure if I can get 3" routed the way I would like. Any ideas?
taking out an engine, knowing what is doing what and making all of this work you guys must have learned that at school or how does it works? (I'm jelly)
2.5 inch shortie headers on reverse sides of the engine may work. I'm not sure if hoses or anything will get in the way. 2.5 inch pipe to a t4 will support more then your goals. .96AR is a tad small on a 76mm on a 5.4. Although these engines only go to about 5000 rpm I would think a large 5.4 would have it spool quick and possibly taper off to soon. Might be a trial and error but I think like a 1.xx AR may be better. Also I'm around 450-500rwhp on stock trans and bottom end. Twin is over 475rwhp on stock bottom end. Set your sights over 400 the truck can handle it. On a built motor the only thing holding us back is fuel pump setup. Fore had a kit but only a few made it out. Custom fuel setup will be needed. Hot rod cams work excellent with my Whipple and I assume will with your turbo even though turbos are sensitive to cams.
I would think a 3 inch exhaust pipe could be routed by the drivers side exhaust header/manifold. There is a ton of room. Then it can cross over to the passenger side the way the stock exhaust currently does. I would run a straight pipe with gotts o2 mods (spark plug foulers on oxygen sensors) for no cats. My 47lb injectors still have room to grow on my setup. I would run them or 60lbers. Mass air setup means you can't vent to atmosphere as it will confuse the computer making it think the trucks lean.
I have a set of 42# injectors I'm going to run for now. The down pipe is just going to be dumped into the passenger side fender well for now, later on I might run it farther back.
I just want to stay 400rwhp for now just to play it safe. This is my only vehicle at the moment.
