Shaker im very interested to hear about this 12.95 run you did. So you were completely stock except for a 2 barrel and a turbo? What carb did you use? How much boost did it take?
The 12.95 was not with a 2bbl. It was with a 600cfm Holley DP. The engine was stock except it had shimmed valve springs. It still had the exhaust manifold on it as well. I was running around 21 psi of boost. The car would have gone faster except for the skinny 215/75/14 tires. this was with a 2.5" exhaust system and a stock 87 GN turbo.
I eventually upgraded the turbo, built a header, and put a 3.5" exhaust on the same engine. I put a copper headgasket on the engine and head studs as well. I upped the boost to almost 30psi and the car responded with a 11.77 @ 117 mph shifting at 4700 rpm. Same tires but added 200 lbs to the trunk for a race weight of 3500lbs.
