Default ACTUAL HP gain question? Heads, cam and intake, is it really worth it?

Whats up, I drive a 2002 3.8 V6 and I have some questions about gaining HP. What would be more logical, getting ported heads, cam and intakes on the existing 3.8 or picking up a 4.6 GT engine/tranny and making the swap? Through rpm-mustangs, the ported heads, cam, intakes, gaskets etc..it would come close to $2k. How much more HP would one expect from the P. heads, cam and intakes compared to dropping the 4.6 in there? Last thing, how much would the 4.6 GT engine/tranny end up running me total at the end?

Any feedback is greatly appreciated.

If you put a SSX stage 3 HiPo power pak on your V6, you will add a little over 90 HP which will put you at a little over 280 fwhp = about $2,500.00 by the time your done.

If you do a 4.6 swap you will be at 260 fwhp = about $5,000.00 by the time your done.

A 280 HP V6 is unique and admired and much lighter than a 4.6 and it's components, plus you still only pay insuance on a V6 = close to $1,000.00 a year.

He's talking about flywheel horsepower, or the power measured at the flywheel. AKA crank hp...

rwhp=rear wheel hp
fwhp=flywheel hp
Fwhp= Front wheel hp

Thats usually how I'd distinguish between the two if I didn't feel like typing out flywheel horsepower all the time.

Hey Slego. I know your just goofin because you know more about Mustang engines than most people here. I've been using that term because that's what most people seem to be familier with. The last time I used "brake horse power" and "Crank horse power" it took me an hour to explane it and I'm just too damn lazy to go through that all the time, LOL.

Funny though, LOL Front Wheel horse power. I think my Stang's front wheel horse power is somewhere in the neighbor hood of around zero, errr, something like that[sm=smiley24.gif]
