port and pully the eaton, you will see a nice gain, besides that, Long tube headers... maybe some gears.

do yo unow how much it would be to do all that stuff or no...

SVTeeshirt

not off the top of my head no, wait for some of the 03/04 guys to chip in im sure they can give you more accurate numbers than my somewhat less than sure answers.

nice looking car tho

i was going to get all my pullys upgraded and it going to be 1,300 for it...

sounds a bit high from what i usually see around here, i could be wrong tho, i do know with a port and pulley you can push around 15psi.

Yeah that number sounds quite high, i think that might cover the pulley, port and polish, and some gears lol.

did a quick search for u, its a handy feature, check these they might help a little.

also that reminds me, invest in the head cooling mod.

and i just searched lethalperformance.com and pullys are MUCH cheaper than that, the rest could be labor i suppose i don't have a clue about the prices for labor about those things but i can't imagine it'd be that much, one of those threads also said stagmeirer(spelling) porting is $700 shipping included, and with that port a pully some bolt ons and a tune you can hit 550whp, just look through em to get an idea of what to do.

What exhaust are you running on the Cobra?

562cobra

yup. around 1500 depending on what port you go with plus poolie.

+1 what exhaust?

I would do the porting and pullying before i do long tubes.
