Or a smaller SC pulley with larger injectors and a remap. I think that should be the cheapest route but I have no idea how much boost our motor can take.

 

All good info. I'm having fun already and my dyno time is not til Monday.! I'll get a baseline Monday, install the plenum afterwards, and re-dyno Tues. I plan to do the same thing with the Cross semi-ti exhaust, but it won't arrive til the folowing week.
I agree that forced induction is the way..I have 2 turbo street cars, one that makes 690 and another that makes 1100. But I love driving this n/a car back and forth to work. I don't have to worry about my wife looping it in traffic (in the dry, at least). I didn't buy it for its horsepower value potential. I'm getting great mileage..I wonder what types of mpg changes I may see under normal conditions...?
Ken7258, did you ever find the exhaust dyno sheets?
