im thinking of doing a 03-04 cobra motor/trans swap in my 99 GT how much power and what times should i be running with a pullie. tune, CAI, exhuast and a 50 shot?

i would say around 500 - 550 rwhp. A lot of unknowns though.

BADSEED

if i got a bigger intercooler and used like a 100 shot you guys think i could hit 600rwhp and then i probably need to upgrade my fuel system

Damn what a major modification here. Well for one thing your GT would be a huge sleeper. After you do all that you will need to change at least 3 other things as well. They're just a must and I'm sure there is more.[/align][/align]Wider tires, need better grip with more power[/align]Brakes[/align]Suspension upgrade[/align][/align]

That was be a really nice setup in your GT.

600rwhp? You will need to upgrade your fuel system WAY before then. Good luck getting to 500 without going with a cobra pump/tank.

ooo i know the fuel pump from my GT wouldnt work, but i most likly would have to change the injectors on the cobra motor, and i have pretty wide tires now 275 but probably would just run M/T's street ET's all the time....
if i do the swap i know i need to upgrade the fuel system and traction but would i need anything else?

Even with the 50 shot you will not be making 600rwhp. With a tune exhaust and pullie you will be around 450rwhp. With the 50 shot you will be about 510rwhp.

Agreed. That's a **** ton of work for that set up, hopfully you have a lot of time and money to be doing the swap... Good luck it would be a sleeper for sure!
