V6-V8 swaps

Thanks all;

Just picked up a 99 new edge with a V6; owing a 96 Cobra, I first thought repair the rods on the 6 and make it a dd...but I've located a 4.6 in pieces here for $100...but then again, I see turbos and a Terminator Supercharger w/plumbing locally for $500....ideas/money/time/////

I did the swap. 1998 3.8 put a 302 stroked out to 331. Had to swap out the k member, could of put a stock 5.0 member in but decided on a Maximum Motorsports member. I put a 8.8 rear with 3.73 gears. Could of kept the stock 7.5 rear. I eliminated a lot of harnesses by going with a carb instead of keeping efi so wiring was minimum and pretty straightforward. I put a 5.0 T5 trans in it, I was told my 3.8 wasn't a direct bolt on and had a lower torque rating. I took my time and I used a lot of high performance parts in the motor and suspension so $$ dictated the pace of the build along with too hot summer weather etc so it took me 2yrs start to finish. Did it all myself, made some mistakes along the way and I learned a ton. If I was going to do it again I would do some things different but in the end it turned out so much better than I thought and even though I'm probably not getting all the horsepower the motor combo has to offer I built it myself and it's a great feeling driving it around!

That is just awesome! (although the sight of the empty engine compartment almost made me throw up with fear...)

Congrats indeed.

All the best.

Very very interesting. Thanks a lot for this write up. Now if I ever want to swap my engine, I know what I need to do.

I just completed this. Take my word for it, get a donor. I swapped everything under an 88 gt into my 3.8 coupe. I had every bracket, wire, bolt and part I needed so, I'm really only into it for the cost of the coupe and the donor, pennies on the dollar compared to sorting out every little bit needed. Things that can be used from the 86 EFI are gauges, fuel system and associated wiring (if you are wanting factory SEFI, like I did), rad and that's about it. EVERYTHING else is different.

Why does my comp do that, flipping pics around, dammit.....


I did find a lot of good stuff in the donor. a rebuilt engine, Energy mounts, UD pullies, a Hurst competition shifter, an ele fan, a mini starter. The aftermarket parts alone more than paid for the cost of the full donor.



Overall, yes it is a lot of work but, it really isn't that hard if you do it like I did. The trickiest bit was figuring out the ECM and engine managment wiring but, the system is pretty stupid so, also not that complicated when you realize that. The car starts, runs and is a lot of fun, despite the 2.73 gears out back.

....maybe third times the charm?

How are you 96+ guys still passing the state inspection after modifying an OBD2 vehicle?

I have a complete pushrod 5.0 HO, ECM, and EFI wiring harness outta a 91 Stang, that I’d love to swap into my 04 Vert, but they wont pass it here in NC once its been modified. Maybe the trick is that it has to stay OBD2? Which obviously would require a different Wiring harness and ECM and I would imagine alot more work to wire it in, vs the 2 wire hookup of the old OBD1 wiring harness.

Ok so I'm sure nobody has asked this, ever. I'm wondering about taking parts from a 98 V6 and putting them on a 98 gt like mid pipes, tranny coolant lines, radiator hoses?

 

[chrisdearmond]

So I have a 97 cobra 4.6 dohc and 5 speed transmission will I be able to put it in a 2004 v6 5 speed car

this gets more and more difficult in the later years because everything is more and more tied in to the computer(s) .... anything can be done, but I think that will be a tough one

Stupid computers, messin' with our compulsion to tinker, lol

Why is the V6 to V8 mustang question continually asked? Lets look at 2003 to get an answer. in 2003 their were 60k V6 coupes built VS 15.5k GTs built. That is a magnitude of 4:1. So there are going to be far more Mustang V6 versions remaining, opposed to GT versions. Therefore the question of engine swapping will continue to come up. Shere this might seem intolerable to some, its actually a positive sign that the community is surviving long trem. As the Mustangs get newer, the ability to engine swap narrows considerably. The SN95 and its New Edge variant are the last bastion of vehicles prone to straight foreword engine swaps. Yes the project of swapping a V8 into a V6 chassis is time consuming and costly. But it pales in comparison to purchasing a newer V8 GT. If my cost to swap is $5k to $7k, I'm way ahead of the purchase of a newer GT
