We can do 45R's as well as 70 and 76's for right around the same price $650 for BB / $350 for JB. I have used a lot of vendors from Asia and done a lot of research to find the best parts. This is the best I have found and I use them for a LOT of stuff, no problems at all.

Its the ebay GT45, the dementions say its bigger 1.01AR, Im not sure, Ive only been dealing with turbos for Grandnationals. My GN has a 6776H.

I like the Ball Bearing turbo on my GN you dont need much stall to spool it up! This GT45 spools at around 2500-2800 with a 2800 converter, and 3.08 gear 28tall tire.

On3 70 is similar, 76 is larger, their ball bearing 76 is larger still on the turbine side if I remember right. Really thinking about doing a compound turbo 70mm on3 or S366 and a S480!

ls6 springs are not that strong for 18+lbs IMO

PAC 1218s are only 140 dollars and install with all stock hardware and hold 22lbs like a beast so far

yes, 9-10 psi, those runs were footbraking it and 1.7 60's, need to set the rear brakes tighter so It can build some boost off the line.

What were those injectors worth lsxmalibu? I love your car. THe Mali wagons rule. Especially when the front wheels are a few feet off the ground.
