Well, I ended up ordering the Xcal 2 from MPH. I also ordered RPM outlets Throttle Body & Plenum Kit for $200. How hard is it too get the stock intake tube too fit over a 75mm throttle body? I hope to see some nice gains with the Xcal 2 and the kit. Next is the gears then cams.
It's not too hard to make the stock inlet fit over the 75mm t-body..I'd say the hardest thing you will encounter is getting the damn IAC (or what ever its called) off of the stock plenum..
BTW, regardless of what others say, you will feel some SOTP power with the t-body, and plenum.
