Im getting together the last odds and ends for my turbo build and am looking for advice on what to get for the remaining compnents.

What I have:

Complete 5.3L
truck manifolds
hot side
master power t70
stock 317 heads
2004 ls6 cam
tial 38 mm wastegate
treadstone intercooler
ebay cold side plumbing

what i think i still need:
fuel system (pump(s), injectors, fpr)
oil feed and return (oil blockoff and timing cover taps) + lines
wideband o2 + gauge
blow off valve
methanol injection kit, or run e85 (which is hit or miss around here)
air filter
turbo blanket
misc gaskets

any input on fuel system components, meth or e85 stuff, and blow off valve is appreciated...as well as pointing out forgotten items. thanks!

 

oh yeah...and shooting for 550 rwhp more as a bonus...and will i need something stronger than ls6 springs for valve springs?

 

I used 60lb injectors and a racetronix fuel pump. I don't see you listing a radiator. With modification a stock one can be used. But I have a griffin. Also need fans. My local oreillys had hayden fans for about 50 or less bucks.

 

Oh yeah...I'm planning on keeping the radiator in the stock location and using pusher fans, if my hotside geometry allows for it (it should).

 

- Twin Walbro's
- 80lb Injectors
- Tial Blow Off Valve

 

IAT sensor, 3-4" coupler from cold side to TB, 2.5-3" coupler from MP70 to cold side, misc bolts/metal to make intercooler mount, spark plugs, small cam and springs if you plan on doing it, or atleast put LS6 (yellow) springs on it to make sure the valves stay put, pushrods. Racepartsolutions has a pretty nice 50mm bov for a good price.

Definitely do the twin pumps now, and if you plan on ever running E85, go ahead and get the 80lb injectors. Stock lines are good for over 650rwhp with e85, I have made almost 800 in another car on E85, external regulator, using the factory 3/8, and 5/16 (return) line re routed a bit, twin intank pumps.

This.

I wished that I listened to Steve when I was starting my build.

 

i was actually thinking th400 since they seem to be cheaper.

 

this be a good build you will make great power

 

They are cheaper but OD and lock up is very nice.

 

You might have boost creep issues with just a tial 38.
