Its a turbowerx return pump. Yes on the oil restrictor I'm sorry I don't remember the size of hole. I've had 12psi pumped in and its a little more than I wanna chase around on the street. It gets loose really quick.

 

Literally perfect timing, im finishing up buying parts for my rearmount.. I already have a 5.3 4l80e swap I did 3 months ago on my 98 ZQ8. I went with a GT45. Mannn I just cant understand where to run my dang charge pipe. Im not running an intercooler but I do have plans for a methanol kit.

 

You could run the piping similar to mine except instead of sweeping across the radiator support you could swing into the throttle body from the drivers side after popping up from between the exhaust and brake booster.
Its not an easy task I know but its doable.

 

Nice setup!

 

Quick question man. What size intercooler is that on your truck?
