engine swaps
 

My 1999 GT was recently in a crash and totalled. All of the engine, tranny, etc made it and still run great with very low miles. I plan to buy a cheap GT or v6 and swapping over everything since I have stuff done to my engine and it only has 40,000 miles on it. My question is are there any problems i am going to run into? Can I just swap the computers and be fine? I have a chip with a tune on it for my cams and I have the pats system turned off on the chip so Im hoping that wont be a problem.

should be relatively easy. Having the full donor car and a destination car makes it pretty quick to do whole assemblies. I'd pull the whole wiring harness and ECU and all the crap out of your car and put it in the new car so it thinks its your old car but I'm the sort to do that. So yeah, simple. PATS may be a fun bit though. Seen it be trouble even with chips. It's not an insurmountable problem and I wouldn't let that stop you.

Even with a donor car, trying to put a v8 into a v6 Stang isn't easy. You need more than the engine, trans and computer. The cooling system is different, I believe the engine mounts are different, the drive shaft and rear differential are different and I'm sure I'm forgetting a few things. It can be done but unless every cent matters you're probably better off using a GT.

Get a GT with a good body or recently repainted with a shit ton of miles on it, then swap your motor over and drive train over.

That is my plan, also if i switch the computers and the gauges will my car read at my old milage of 40,000 or the miles from the new car prob deep into the 100,000's

i think it will still show the mileage on that car. i once changed the computer and the mileage didnt change

I havent started it up yet but everything is swapped, and i mean everything so I dunno how the miles would still read 170.000 and not 40,000. The only thing I didnt swap over was the body. Ill let you know what it reads though when I start it
