1999 3.8 swap to 5.0?

snake428CJ · **1999 3.8 swap to 5.0?**

How would I go about swapping a 1999 3.8 v6 with a 302 pushrod V8. I have the block, just need a 'how to' on wiring, plumbing and how it would proceed. I guess what I am asking is for a detailed step by step on how to do so. Thanks

i'd have a place do it...but if you have engine crane + garage + a ton of tools and money + dont mind not having you car for a long time... I would definately find someone who really knows what their doing to help you. I can't help as far as a how-to though.
Good Luck

too much to make it worth it. A modular swap is a smarter idea.

I agree with stangin99 If you want to do a swap with a 5.0 into a 99 you will need donor car because you will need the engine, cross member, complete wire harnesses, computer, gauges. It is much easier to swap a 5.0 into a 94-95. I would swap in a 4.6 or a 5.4.

you may also consider dropping a 4.2 v-6 in.... also very easy...

... and powerful

Same here. That's a lot of headache trying to do that swap. You can find a lot of places who sell complete 4.6 engines for a reasonable price. There's one place in particular, but I can't think of the name. It's outside of Atlanta. They sell used 4.6 engines and even '03-'04 Cobra engines

You are talking about http://www.stangparts.com

for the money you wont be able to beat a 5.0 swap if you build the motor that is... its not easy and at times you will wish you had never thought of it but it can be done... just takes alot of time and efford and money and money (money twice cuz it takes more of it than anything)

if you dont feel like your up to it sell the car and buy a 5.0 in the end you will save quite a bit just doing that.

MPS (stangparts.com) is expensive as hell though! They wanted over $2k for a complete 5.0, a t5, wiring, and computer with over 100k miles on the clock.

Stangparts has a how to on their website to do a swap in for a 5.0L into a V6 stang, I think it was an older model but you should be able to get some ideas. You will most likely need a 5.0L computer for sure, and a lot of other stuff the donor car thing would be the only way to do and don't even think of hiring someone to do it, that would take a good bankroll. As someone else said, selling the 99 and buying an older stang, fox body or 94-95 would be a better way to go. Then the 5.0 in a GT is already there.

actually a modular swap would be harder, the only reason you'd want to swap engines in that late model of a car would be to go to pushrod for some reason, the mod's are great motors though, and it'll be much much cheaper to sell your car and buy a v8 than it would be to swap.

oh btw, you won't need a cross member.. you will need everything else he listed plus trans housing, and well I won't get into that
its a pain, I did a 4 cyclinder to v8 swap but I did it because I wanted to learn, it ended up costing me just as much as I had bought a v8 to begin with and I had lots of time in it, DEFINETLY A COOL PROJECT THOUGH!

no, a modular swap would be a lot easier. The 4.6 motors use the same k-members as our 99+ 3.8s and already the fuel lines as well as the basic electrical done.

Swapping to a pushrod you have to convert to a return style fuel system, put in an older computer and then splice all the wiring in, among many other PITA changes.

A modular swap is a hell of a lot easier.

Ponycarman · 06-11-2005, 04:46 PM

Computer? wiring?

How about a carb and a regular electronic distributor? Make swapping a 5.0 into a 99 stang easier. No need to worry about EFI with the 5.0 swap, since it won't be smog legal anyway.

I forget about all that computer stuff..

the k-member for a 3.8 and a 5.0 are the same though.
