I bet most people would be surprised how little their cars actually make on the dyno after these mods. Seat of the pants feel, or thinking it's faster cause it's louder is one thing, but solid horsepower numbers are another. But hey, who am I to argue, I don’t’ have a dyno in my garage, but I have seen guys strap on a hell of a lot more parts than that and come up way shorter than they’d expected.

The intake would help some, but after that, the real problem in this equation is still going to be your heads. A 70mm T/B will do nothing at this point, nor will the 24lb injectors. As a matter of fact, the 65mm will flow up to 400fwhp, so jumping to a 70mm really won't change matters better heads, or not. What you’ve really got to do if you want to make any real power is start saving up for a port job or aftermarket heads and intake. Then worry about the smaller secondary mods like Throttle body, exhaust, cam , etc.
