Fox LQ4 S475
Fox LQ4 S475 I started this project in November. I have always wanted to build a Fox body, but never had the money. My first Fox was as a senior in high school. I have had a few since. But here is my latest.

Further inspection came up bad. The cylinder walls were scored and the block needed to be bored .010 over minimum. This was not good news because my plans were to use a stock short block and 317 heads. I had the machine shop tumble the block and then I sold the long block to a friend of mine.

So I bought a 2006 LQ4. It had low miles and the later version had stronger rods and pistons.
I went through all of the bottom end replacing all bearings and rings. I ordered a custom bullet cam for use with the S475 and stock heads, installed ARP head studs, single roller timing chain, LS7 lifters, Melling oil pump, and a GM performance muscle car pan.
Fast forward three months and it is all assembled. I decided against using the Factory ecu and went with a Holley Dominator EFI, DEKA 80lb injectors (for now), a Edelbrock pro flow intake and throttle body, Holley valve covers and as of now I am using the truck spacing on the accessories.
I fabricated the hot side out of 2.25" 304 using V-bands on some factory manifolds. It is feeding a T6 divided flange and sitting on top is a Borg Warner S475 with a ceramic coated turbine housing.
I initially installed the 4L80e because the of the Holley control feature, street ability, and coolness factor. But one quote of a built 4l80e shot that idea completely out the window. So I decided to have Finish Line Perfromance build me a TH400 with some goodies including a circle d convertor, reactor flexplate, JW ultra bell, brake, etc...

I dont have any pictures of the tank, but I am using a Aeromotive eliminator pump in an Aeromotive stealth fuel tank using 10an feed line into an Aeromotive Y block coming out dual 8an feeding the front of the fuel rails and ending out the back into the fpr. As many know these fittings can add up. I have have been using mostly redhorse and although chinese the quality is hands down better than most imported fittings.
As far as the cold side goes everything is vbands except for the throttle body elbow. It is 4" out of the turbo flowing through a Chiseled Performance 1500hp intercooler. The downpipe is 5" 11ga aluminum coming out in front of the right front tire. The radiator is a champion cross flow with dual Squall fans using 16an braided hose to a factory water pump.
I dont seem to have pictures of all of the intercooler piping welded out and the intercooler and radiator mounts done. But i will post them up some time soon. This is currently where the car is as of now. I have to wire the car and finish the cooling system before I can start it. but it is close. I will update this thread as I continue. Also I left out the chassis, suspension and brakes as they don't really pertain to the LS swap, but I did install full TeamZ front and rear suspension and a pre bent and notched cage that has been installed, inspected and NHRA certified for 8.50. The brakes are Aerospace Pro street all of the way around.
Its a Wolfe Racecraft billet 10an turbo return. It also comes in 12an. Very nice piece and it tuck it up closer to the turbo versus a npt flange with a npt to an adapter. Its tight, I'm not going to lie...

As far as advice with fitting the turbo. I MADE it fit, LOL. I placed the turbo in various different spots and weighed out the pro's and con's of each. Honestly I wanted the inlet to face front and center but that would KILL the street ability. This is essentially the easiest spot to mount that dumpster *** sized turbo for me at least. I will be making a 3.5" down pipe that goes dual 2.5" out the back one day.
