Lil RED Turbo build
Me and my friend Dustin at www.performanceporting.com recently put a turbo on my 1990 325i convertible. We first performed a leak down test on all cylinders and it had less than 4% which was good for a car that has 180,000 original miles on it. Yes the car was well maintained in it's 25 year life. We currently tuned it with MegaSquirt PNP and its running on corn "e85" We were testing the limits with the boost control and was pushing 24lbs of boost. We decided, with the car being stock including head gasket, clutch, etc. we stayed at 14lbs of boost and pushed out 260whp. It is holding strong and beats new Mustang GT's and hurts feelings. It is for sure underestimated, and I'm not saying its the fastest, but the gear ratio, turbo setup and overall car dynamics gives a mean punch all the way thru the gears. We haven't ran a quarter mile but my Tunes guy thinks mid 12's as is. We will keep this one as we have it for the time being, but are building a 1986 stroked es as we speak. It'll be gutted, caged, stroked, boosted to 30lbs and not stopping till we hit 600whp. I hope this helps you in deciding on your build.
