BoostHard1210 · July 10th, 2007, 07:28 PM

HEy all..Anyone know where i can get 03 04 cobra internals? I here they are forged i have a new gt block and want to put that in there for about 15 psi.. will it work? all i can find is bored stuff or kits that are to much or that are for alot of boost

sonicblue · July 10th, 2007, 09:04 PM

it will work. i have a cobra crank and rods in mine. just search ebay and the mustang forums to see if anyone is selling them.

BoostHard1210 · July 10th, 2007, 11:33 PM

Are you boosting? are they expencive?

acmillr · July 10th, 2007, 11:39 PM

Pistons and rods

you might try summitracing.com

sonicblue · July 11th, 2007, 07:30 AM

yea mines boosted. i got a deal from a friend so they were pretty cheap

BoostHard1210 · July 11th, 2007, 06:56 PM

how many PSI you pushing??

ujslost · July 11th, 2007, 07:16 PM

might find you a navigator motor also

BoostHard1210 · July 11th, 2007, 11:47 PM

Are the rods the same size?

ujslost · July 11th, 2007, 11:53 PM

that i cannot give you the answer to, but i would think so. maybe someone else knows

BoostHard1210 · July 12th, 2007, 01:25 AM

You think if i put good forged rods and just stock crank and stock pistons i can push to 15 PSI???

MustangMatt96GT · July 12th, 2007, 01:39 AM

Why risk it? Your are going to have to take off the pistons to do rods anyway!

IMO u should use all forged internals to safely run 15 psi. i think it would be too risky to use a stock crank

13psi but on a stock motor it would probably be more like 15 or so. soon i will be pushing 18 or so......just got to get a bigger blower to do it. the forged cobra internals will easily handle that. i would also def do the crank since you are already inside the motor. that would be a expensive finding out the hardway lesson

The stock crank is more than enough up to and beyond 600HP. Don't weight your engine down if you don't have to.

SWEET2KSTANG · July 12th, 2007, 08:19 AM

there are a few guys that are putting down 660-670 on a stock crank without any problems. 12psi is starting to push the bottm end pretty hard, it depends on what other mods you have that will either help or hurt running that much.

Do you have a procharger?

True might as well

02steedagt · July 12th, 2007, 12:02 PM

you dont necessarily need to forge the crank... the stock one is pretty good, plus like adam said... its a lot lighter than the cobra crank. pistons and rods should do.
