Where is your car??

You are not building the turbo setup without the body on are you?? :_paranoid

No, I will have the body, steering shaft, steering gearbox, inner fenders, rad support, radiator, and fans in place for the build. :)

That is good. It will really allow you to put the turbos in just the right place to make optimum clearance all around.
I wonder what a set of custom stainless direct bolt in LS1/Chevelle tubular headers would be worth? :_paranoid

well i would guestimate that 1500 bucks would be a good compromise, mabe more, but for every dollar you go up the number of potential costumers goes down...

but back to the hijacking.. you mention tuning, that implies that i would need some stand alone fuel and spark CPU... ?? 8 coils.. what is compatible with that... autronic, haltech BS3?

$1500 for a pair of 321 stainless headers is not reasonable. You'll spend that much (and more with the trick collectors, etc.) just for the materials.

Aeromotive fuel pump, lager fuel lines,stock coils, stock comp, and EFI Live.

just did the math my self... i guess 1500 is wishfull thinking.. it looks like ot takes about 18 90deg bends.. 5 feet of straight tubing cnc flanges and quite a bit of time...

it would seem to me that larger injectors were required.. are the oem ones saturation or peak and hold? i havent been able to find bigger saturation injectors than 60 lbs. that should be enough for 600 Hp in a turbo engine.. how do you fuel 1000 ponies injector wise?? are you running 70 pounds of fuelpressure or how do you accomplish it??

OEM is high impedance (saturated). You can get up to 75# from http://www.rceng.com/ and up to 83# from http://www.venom-performance.com/nf/...niInjector.cfm#

I'd say a 75# to 83# would be safe. The Mule has 65# and made over 1000 HP but the duty cycle was high.

I run a 96 lb injector with an inline injector driver. It changes the PCM signal from high to low impedance. Works very well and is actually more accurate at controlling fuel then the large high impedance injectors, they react faster.

A 60 lb injector with 58 psi fuel pressure will support 600 rwhp. I run an A1000 with 45 psi and 96 lb. injectors and have more then enough fuel. ;) Maybe someday I will turn up the boost! :_paranoid

A set of steel twin turbo tubular headers could be made and sold complete for roughly $1500. That is not all that bad.
Stainless adds cost from a much more complicated welding process, and additional cost of welding gas, filler rod, and tubing/flanges. Stainless 321 would be between $2500-$3000 complete, If I were to ever build and sell them. :_paranoid I do not know about others pricing.

Thought that I would mention
 

I am using basically the same S&P pulley system. I was told that hard high rpm runs will throw off the harmonic ballancer cover you have installed. Very tough to get it perfectly mounted with no run out. Call S&P and ask for Lambert for verification.

I was going to use the same and decided against it after that bit of info.

Hope this helps....great project by the way
