TReX cam + FAST intake or suspension, ls6 & tb?
I am about to take the plunge into MTI and take advantage of their financing opportunity. I am thinking about either getting a trex'ish cam kit and an LSX 90 intake or just get suspension parts from there and get an ls6/ported tb combo elsewhere. What would be the best route to go? I know that there is more power to be had in the trex/lsx but it sounds like it'd be at the expense of my tranny or something.

It is critical that you budget good money for tuning if you do the big cam and FAST 90. And I'm not talking about a WOT chassis dyno tune or a mail order tune, but a comprehensive driveability tune...perferably without a MAF. If you don't do that, you'll hate the combination and so will the rest of your car. Tuning is the key.

I dissagree Patrick. Dragaholic had a T-Rex cam with a FAST 90/NW TB with a TH-350 and a 5500 RPM converter with an 85mm SLP MAF and his car idled like a dream. The part throttle was just as good. He couldn't driven the car around town had he wanted/needed to.

But when I ditched the MAF and speed density tuned my car, it became infinitely more enjoyable to drive, so much so, that I can now lug my .644 lift cammed, FAST 90 equipped vehicle with 3.42 gears through school zones with no problem. I'm talking cruising at 900-1200 rpm, no problem. Dragaholic had extensive tuning on his combo. The only way I know this is he complained so much about his MTI tune that he had to go to another shop to fix it. Tuning is critical, regardless of whether you run a MAF or not...in fact, it probably takes more skill to tune it to run right WITH a MAF.
