It didn’t make the power I wanted. It made 565 to the tire at 15 lbs with a cheap single T4 master power 70mm turbo . The build was pretty much out of curiosity. It drove awesome and was quick as **** on the street. Naturally, spooling was a tad laggy but was making good boost from a stop light before I got through the intersection. I changed because I hurt the #7 piston and swapped to an iron block forged motor. I didn’t wanna chance an issue with the oiling system and scavenge pump. There was a guy here that did a T6 rear mount that made like 850 RWHP. It’s possible to make good power but I opted to build my own front mount kit.

Should i replace lifters while im in there? When i was diagnosing my oil smoke from mufflers issue( turned out.to be a bad valve seal) i found one rocker tip that was gouged(worn) . I filed it down and ran the car the rest if the summer. Could this be caused by a bad lifter??

don't know how big of turbos you plan to run (or how much boost), but you mentioning low CR being better earlier... that's good for if you're cramming a crap-ton of air down the engine's throat. if keeping it less than a dozen psi or so, you'll have a bit better drivability & response by maintaining low to mid-10s CR.
