hello everyone i was wondering if a 2006 mustang v6 4.0L engine would be compatible with a 2008 pontiac g6 4 doors. i found a engine of a mustang with only 20k miles and the seller put a price of 1000$ for it because his car was ccrashed and the engine was still in good shape and hes selling it. if the engine is compatible with the g6, how much could the total cost be? what else do i have to change? or even.... is this a good idea? lol. thanks alot for ur advice guys.

and also, i am looking for a good option of engine for my g6. is there even a possibility of changing the engine only? i would be looking for a v8. but a powerfull v6 would also do the job :p.

I would not go with the mustang V6. Ive raced so many, it just doesn't seem like they put out any power. I think like 215hp or something. It'd be alot more satisfying to get a 3.6l DOHC from the GXP with 252hp. I know those have power. Also, with the mustang engine, it's a rwd engine made for a rwd drivetrain. If your looking for an engine swap, go with the GXP 3.6L engine. I'd go ahead and get the 6 speed auto that comes with it to. And if you want a V8, if your willing to put in the work, the grand prix GXP engine and trans would be the way to go. It's a 5.3L V8 with a fwd drivetrain. But I have no idea if it would work, it's just an idea.

ok so technically, i need a v8 engine that works on FWD. i saws the GP GXP v8 engine that develops around 300 hp. its pretty impressive, but would i be able to put in a different v8 engine with more hp that would have FWD? does it necessarily need to be GM?

Let me preface this with anything is possible given you want to spend the time and money to do it. So yes its possible. However I would say its not feasable to put a V8 in the G6. There would be an awful lot of work done to modify fener wells and firewalls to shoe horn a V8 into the rather cramped G6 engine bay. I have a GTP with a 3.6 and I can tell you that thing is really wedged in there.

I think if you were going to do this a whole lot of research would be needed before you bought anything. Even if you could get the GP V8 in there and get the tranny in there the next issues are these:

Wiring, larger breaks, beefier suspension, fuel pump change, computer/trans computer stuff, exhaust routing, steering box relocation, battery relocation to trunk for sure and on and on. As someone who has put small block and big block chevies into S10s and small blocks into rangers I can tell you there is an awful lot of work involved with a project like this and unless you have access to a lift and a full compliment of professional level tools and knowledge you will have an awful hard time completing this. The chances of you having a tranny and motor sitting in your garage that are listen on Ebay or craigslist for sale are far higher than you doing a total V8 retrofit in 1 years time or less. If you pay to ahve someone do it thats another story.

If you are looking for more power I would give Cottons performance in Agawam MA a call. The specialize in turbo 3.8 that came in GNXs and T types as well as the 89 Trans AM. These motors have a TON of possibilities with an arse load of aftermarket parts available. One of those 3.8 V6s and coresponding tranny could easily get you into the 13s with very little work beyond the transplant.
