Adding a turbo to my existing LQ9 powered fox body. Car goes 7.0's @ ~98 w/just the LQ9, headers and a cam. Going to add a B/W S475 to the mix and see what happens. Any input would be great. I have my converter out to be rebuilt for the new combo, any advice here would be great as it will need to be just right with no trans brake.

Stock LQ9 - 364ci (4in bore, 3.622in stroke) 10:1 c/r

Stock 317 cylinder heads - 72cc heads (2.00/1.55 valves)
Cylinder Head Flow:
Lift......Int...........Exh
.100" ..64.8........53.3
.200"..142.1.......111.6
.300"..204.3.......146.8
.400"..233.5.......164.9
.500"..250.0.......174.2
.550"..251.2.......181.2
.600"..253.0.......184.4
Test bore = 4.030"
Exhaust tested without pipe.

LS6 intake w/ported 78mm throttle body

TSP Tsunami Cam:
Cam specs: 235/240 648"/609",111 using Lunati's .660 spring kit.

Turbo Specs:
S400-75, 1.32ar, 96mm turbine wheel T6 flange
Running through manifolds, 2.5" cross over, 5" open downpipe. 2x38mm wastegates and 50mm bov
31x12x4" Godspeed intercooler, 3" piping

TH350 w/no transbrake, 3.73 rear end/spool, 28in tire


Car is probably around 3k pounds, going to have my current LS3 injectors resized to 80lbs @ 3bar by FIC, plan to run on 93 pump gas, fuel system consist of an Aeromotive Eliminator, -10 feed, -8 to each rail, Aeromotive boost referenced regulator, and -8 return. I tune myself using HP tuners and plan to run meth injection most likely with the 10:1 c/r.

Any suggestions on the converter and any input on my setup would be greatly appreciated.

What are you asking? You're not reinventing the wheel, just do it and quit talking about it

starting the fab work this weekend. just wondering really if anyone has a similar combo or any thing that i should consider doing differently really.

everything you have looks good man, I got my converter from Circle D and I love it...its really tight around town but loosens up real good on the trans brake

Combo sounds solid. Take it slow tuning if you've never tuned an FI combo before. Set your PE and BE to 11.0 or richer in case you have a lean spike while tuning.

It might be just me but I would go towards a more boost oriented cam other wise looks good any hp goals

650-700rwhp on a conservative tune is my goal

Looks like I am going to be swapping cams for a 230/230 615/608 115 + 1

Any opinions here?
