Hey, new here!
Just wondering how much SC boost can a stock 03' engine hold?
annnnnd what internally would be a good idea to swap first?

 

[mustangmanic]

9lbs at max. stock internals can only hold 450rwhp before going south. i'd do 400rwhp just to be safe... make sure to get an amazing tune as well

 

[ArmyChargedGT]

So what inside should be swapped firsT?

 

[00vabchgt]

get forged rods and pistons. the cast iron crank can hold up to about 600 hp, but if the bottom end is ripped apart, you may as well replace it also. little note: if you replace your crank with a forged one from a Cobra, you'll need a new flywheel. the 03 crank has a 6 bolt pattern, tha Cobras are 8 bolts...

with a GREAT tune, on a intercooled kit, and you dont beat on it too much, or over rev the motor, 13PSI is safe.

i would still start saving for a bottom end though.

+1 on bottom end...looking to forge this summer

 

[ArmyChargedGT]

k, probably not looking to go that high. the mods it has now are as follows...

Bottom end should def come next?

 

[workinprogress]

oh yeah

if you plan on goinf FI, you may as well do it. not necessarily right away, but you probably will have to at some point. i got lucky (?) i spun a rod bearing a few months back and since the mototr was going to be ripped apart, i spent the extra cash and got all forged goodies to go in the bottom end...

how much did u end up spending on the forged goodies ?

 

[00vabchgt]

how much did u end up spending on the forged goodies ?

little over 2 grand on the parts with shipping and balancing. still waiting to see the final tab for the labor...
got the rotating assembly from Sean Hyland Motorsport

 

[ArmyChargedGT]

how much power do u think my mods are making?

 

[00vabchgt]

when you put the blower on, did you get it tuned, or is it a canned tune or something. best way to find out how much power you're making is to strap the car to a dyno and run her...

 

[ArmyChargedGT]

The car is prof. tuned
Yeah, would be the best way to do that lol
you think 380 to the ground?

 

[00vabchgt]

that's probably a conservative estimate...

 

[ArmyChargedGT]

What kind of pistons and rods should i go with? are the K-black pistons worth a flip for the $$

 

[00vabchgt]

i went with this.
Manley rods and pistons, FM bearings and rings
Forged Cobra crank
i paid $100 less, though. i guess the prices went up a little...

 

[20gtvert03]

did you get them standard or over sized?

 

[00vabchgt]

0.020" over, 17cc dish...
