just remember that these motors have alot in them...
when you start increasing the power the smaller things start to break.
first your rear G80 might/will eventually grenade hopefully it wont take out the gear and drive shaft with it...
trans will be the next to go burning clutches breaking a pump who knows.
engine should be good for healthy power as long as your tune is good.
I thought the same way you did my brother has an 03 cobra i wanted to at least give him a run for his money...but then he started modding it and he makes way more money than me...plus there is the weight issue i would have had to overcome...
you gotta pay to play...think over what you want to do and slowly build what you want part at a time if the money is tight. Thats wut I did...first thing a tune and headers(installed headers and exhaust myself) then the cam and springs(had tyler help install) next was rear gears and an eaton(shop did that) I then had virgil retune my truck and it was a blast to drive....Until the tranny went...had Jerry build me a new one with a good stall and Danny and Tyler helped me install it.
