You should be damn close to the 400whp mark and the car would be fine stock as long as you didn't add any more considrable power.

o you will be fine with that setup just keep it around 400 i know kb sends their tunes with the kit are safe.

Why dont you get a Mach 1 then supercharge it??? You will see better gains since it is a 4 valve... It also reacts better to other mods vs a 2v...

go buy a 99 cobra and kb that, you'll be much happier with the end results.

Well definitely the GT with KB hands down. MACHs are nice but if it is the same or even abit more money GT with blower than it will be a night and day difference. Obviously if money not an issue then buy the MACH and put KB on it. I recommend keeping hp below 400 rwhp with stock internals.

To put this in perspective, my GT is in need of a new motor as I was pushing 400 rwhp and loved to hammer it needless to say I need a new motor. So, I was thinking maybe I will sell my blower and just go n/a 300-310 rwhp to save so dough. Well, I drove my buddies stock 2003 MACH 1 with 3000 miles on it a 5 speed and made my decision to keep my blower as the MACH was not even remotely as quick. Bottom line if you cannot have both my friend it is hands down GT with KB.

If you get a KB blower though without forged internals, you can't go crazy with boost. I'd go for a Mach 1... you can't replace the potential of a 4V. However, I agree with the other guys on here... an 01 Cobra may be the best of both worlds.

if your gonna do a blower

get a 99/01 cobra the motor is setup up more friendly for boost compared to the machs CP ratio

99/01 cobra = boost

03/04 mach = N/A
