so ive had a 2002 v6 the last few years and ive been recently looking into swapping a 4.6 2v. i can get the wiring harness, computer, and complete motor for about $600-$700 from a friend. i have a couple friends that would help me with the install. my question is, would it be worth it? im in college and wont be getting a new car for a while. my goals are to run a 2.6 kenne bell with about 20psi once i get forged internals. if possible, id like to see 600+ rwhp. let me know what you guys think.

[gooberhead320]

if you're going to be spending that much money to make a car do all that, then just get a termie... supporting 20psi isn't gonna be cheap, thats for damn sure

[zigbigadoru]

just get a 5.4 2v instead

you'll spend more time and money doing this swap then just finding a GT in the first place.

It's not just the motor that's different. Spring rates, brakes, tranny, and rear end are all different; those pieces that you chose to not replace will either be weak points and need to be replaced later, or cause a safety issue.

Motor swaps escalate quickly. Take what you think you're gonna spend money and timewise, double it, and you're in the ballpark of what it will be if everything goes right.

let me elaborate some. this will be my future project car. when all is said and done, it will see a 6speed tranny, built 8.8 rear with 31 spline axles, full upr tubed suspension and coilovers, built 4.6 2v with a kenne bell blower. do realize that all of this would have to be upgraded in a gt as well. the stock rear, block, tranny, and so on couldnt support 600+ either.

Okay, then I ask why you would want to start with an iron block 4.6? Why not find a teskid motor? Or a 5.4L, as was asked earlier?

I'm not criticizing what you're doing, just making sure you know what you're in for. So far you sound more grounded than the rest of the "I wanna swap my sixxer" crowd, so props to you for that.

i like the simpler 4.6. i mean thats what came in the gt's and i actually have a friend that was gonna sell me his entire motor. ive seen the vids of the kenne bell 4.6 gt's and thats all i really want. i love the new trickflow heads coming out and i really cant afford the cobra type motor at this point. all in all, im looking for something to hold between 6-700rwhp and this seems like it. i know the 3.8's are capable of it, but i just dont like the turbo nor the sound of a v6 anymore. there is nothing, absolutely nothing, in my opinion, that beats the sound of a screaming kenne bell on top a v8 motor!

now, if in you guys opinion, the 5.4 would cost about the same and produce a little more power let me know. i dont wanna be doing any custom fabrication. ill be doing the swap with the help of two friends. to some, this swap may seem out of the blue, but ive been thinking about something like this for quite some time.

[zigbigadoru]

the 5.4 is essentially just a stroked 4.6 and would require pretty much the same stuff as the 4.6. it would cost about the same as a 4.6 as far as i know and produce more power. also if you decide to go 5.4 and get tired of the power you ca always stroke it some more to a 6.2L!!!! now tell me do youFRAMlly think a 4.6 can hold up against a 6.2? i think not

nah man youre right on that. its just i have a 4.6 complete motor sitting in front of me with the computer and wiring harness and everything else. but i guess since ill have to break it down and stuff forged internals in it, i might as well hold off on that plan. part of me wants to toss in the motor for now just to have that v8 power and sound, but it really doesnt make sense if i know ill be taking it right back out. At least you guys arent bashing me unmercifully like on 3.8mustang.com. It is a budget build, but i want it done right. Im looking to spend around $20000-$25,000 on it.

[zigbigadoru]

ok let me put it this way. i HAVE a 4.6 and i WANT a 5.4. make sense? im only going to spend like 10k hopefully on my full build. granted it will be over the years.

[Techniq]

I have a 4.6 and I wanna keep it... DOCH V8 32v.

[SVOpower]

32 Valve!!

[zigbigadoru]

hahahaha tell ya guys what you can keep your 32 valve and ill take the 5.4 k? man i am so stoked now, i should be getting my new 5.4 hps intake manifold soon.

[Stroker281]

Just get a Cobra and upgrade the charger!

[stangdriven]

dude if you want to run 20 psi on a 2v...yea its very possible but a lot of work, better off geting a 4v or 5.4 2 or 4v setup...me i have 96 mustang thats a 6 and im gonna be buying an aftermarket block from mmr.....not sure 4.6 or 5.4 but its the monster mod...yea i havce to buy the heads cams all that seperately, but im also redoing the entire car from top to bottom.....mine will be worth it, but just doin the engine swap.....take the advice on here, but its all uip to you man......

well im building my whole car from top to bottom. i basically have all the appearance stuff i want. just need a cowl hood to clear the kenne bell.

whats a DOCH V8?


Anywho, good luck with this build man. Sounds like your going to be completely redoing your entire car. I would have suggested going with a 4v matched up to that 6 speed. Its a much more practicle platform to try to get 600 hp. But to each his own.

[yojoe600]

i say if ur gonna spend 20 grand buy a 04 cobra in the first place

[Fluffy The Rhino]

Romeo 605.

Oh, and if you drop in that motor, do you have the manifolds, midpipe, and exhaust all ready to go as well?

[mmikeclass06]

as well as everything to swap from vacume to hydroboost brake system. that is what ate my bank account when i swapped from 3.8 to 4.6
