Default Engine Swap

I have made up my mind. I have been stationed in Iraq for quite some time now with nothing to do other than think about the possibilities for my car. See i have a 00 v6 and i want more power. It just doiesn't seem logicle to me to start with a lower hp platform in the first place. I have looked at every route. Supercharger, Nitrous, Stroking the block, overpriced supersix H/C/I packages. It is going to cost three grand either way. Now i asked a question earlier about swapping engines to a gt and got all those responses. It just makes more sense to me to start with a bigger engine. I can't sell the car and buy a gt but i have money and i want to put it into my car. It seems like modding a v6 is pointless. Say i can get a 4.6L engine including tranny, ecu, wiring harness. Do any of you on here have any idea how much it would cost beyond that point to drop it into my car and what else i would need other than possibly a 8.8 rear end. Your advise is greatly appreciated.

Umm the advice im goin to give to you is to put a supercharger into your 6...why you ask? Because its cheaper than doing a v8 swap and you will have more power than a stock gt.

They sell supercharges for V6s? Really, I didnt know that, I alwayz thought they only sold twin turbos for anything V6 and under.

On another note for for the twin turbo, if you get a gt engine you're gonna need a gt suspension, bigger engine=more weight. You're also gonna need a new speedometer, if you get the TT you're gonna need your exhuast ceramic coated, and if you get a gt engine you're gonna need a gt exhuast, or the ceramic might work too. A TT is like $1500-3000, maybe more, Im not too sure, and an engine bout $4000-$5000, decent one anywayz, and are you planning to do this all yourself, cuz if not the labor's gonna kill you, you're talking about days of work for the new engine and stuff put on thatz gonna be alot if you take it to a professional. Do youself a favor, just but a GT mustang, it's got more power than a v6, it's got the leather interior, foglights, if you put an exhuast on it then it will sound awesome, it will already have like a low profile tire rims on it if you find a good one. It's your best bet right there, GT.

Default RE: Engine Swap

The swap is extremely costly, much more than it would cost to mod your sixer. There was one guy on here that did it, and I believe he said it costed him nearly $6500 to do the whole swap, because there is a lot more to it other than the engine, tranny, rear end, because you also have to remember that the GTs have different shocks/struts, ecu, driveshaft yoke, and a million other little nick nac parts. In short, if you want a V8, then sell the car and get one, if you want a fast car, them mod the sixer, you could do a lot of damage to your sixer with the approx $6500 price tag the swap brings into play. Can it be done for cheaper, probably, but that' deffinitly a good ballpark price.

In case you didn't notice man he said buying a GT was NOT was not an option, and yes people will tell you you can put a s/c or tt on the 6 and they are right, BUT think about it, you put that tt on and make 350hp ok, well then ur weak trans and rear end cant take it so you hav to upgrade to the 8.8 and t-45 or t-3650 trans anyways. People on here will cry all the time about how terrible an idea it is to do a v6 to v8 swap, however in reality as long as you know wut your doing and can do the swap with just urself and a buddy and are smart enough to find a wrecked gt with low miles, the swap can be done right for 3-5 grand. But I will not lie to you, there are going to be headaches and a few electronic problems are going to **** you off, but in the end if you done everything right and pick out a good donar car with less than 35k miles you'll be very happy with your new gt with v6 insurance. ( Just dont wreck it)
Here is what i pulled off the GT I found to do my swap with
4.6 sohc v8 with t-3650 trans
8.8 rear end
speedo, sway bar, motor mounts, exhaust manifolds, all front acc.s, rear bumper

You can pull these items off a GT as well butt I upgraded to aftermarket brand instead.
suspension, exhaust(midpipe, catback, hangers), wheels,

I'm sure I've left something out but its early and I just woke up im going to get me some waffles.

your right, a 4000 procharger will NOT let you run with a GT, it will let you run with a mach, IMO 5k for low 13s/high 12s??? > 5k for mid 14s

you got those responses cause some of us actually know what were talking about, and its either to use the v6 thats in your car or trade it for a GT, and you still have to notify your insurance company so they can adjust your premiums, and if you do wreck it, even if its not your fault, its voided, meaning you get nothing, not even for the shell

and as for upgrading, theres a couple of people on 3.8 running lsds (not tloks auburn/detroit) along with a girdle and are fine for the rear, upgrade to a t45 or t3650 tranny? not only are they NOT any stronger then a T-5 but they both suck as well, (my buddies t3650 got rebuilt at 13k on a mach), a 4R70W auto with a jmod will be fine till around 400 rwhp, as for a 5 speed it would need to be rebuilt or upgraded to something like a t56

for $6500 your car can be running 11s, bigger does not always mean better

I dont know how much money you want to spend and this may sound crazy, especially on a Mustang forum, but if you really want to do an engine swap, I wouldnt put the Ford 4.6L in. I'm a huge Ford guy and will always be, but some of the GM engines (LS1, LS2) arent too expensive, and they make great numbers compared to the Ford engines. You'll have to replace A LOT of things, and it may be more expensive, but in the end you'll be making more HP.

And I like your idea of wanting a bigger engine. If you do get one, you should make it N/A. There's nothing like beating a guy when he has a blower or nitrous and you just have all engine with no power adders.
