I use a 4an feed with a restrictor. If you guys are making a rear mount setup, make sure you put a check valve on your feed line. If you don't, oil will puddle in the turbo while the engine is off and push through the turbo seals. I got my check valve from sts.

 

wowzers sold on the gt67 haha

What are some good reliable budget brands for waste gates and blow off valves

 

If you are only looking for 100extra and want to keep the long tubes why not pick up a second hand supercharger? Much much easier and will deliver no problem.

 

I love the turbo sound

 

Dont forget the duck call as well for bov

 

duck call is more of a not working too good BOV.. and surges the compressor


But i had the Garrett 60mm with a .86? turbine housing.


here is from my dyno post back in 2009..
bone stock LQ4 thru a 4L80E in 2nd with the converter locked on a Dyno Dynamics stingy dyno
44# injectors and a Walbro 255. Turbo was maxed out.. look at the torque falling off fast.
Lots of torque down low tho.

Your not goin to get boost at 1600 from off idle, more like 3000rpms.. but cruising with the converter locked you can get boost down low around 1800ish.
