HELP NEEDED questions about engine swap

prunedawg · Sep 14, 2004

I want to swap out the engine in my 97 gt with a 97-98 cobra engine or a 99 up PI engine, what do you think would be more straight forward, i know the Gt engine will be cheaper, but im concerend with the full system. I know the 99 and up engines had the returnless fuel system. And also will my stock computer be compadible with either. any insite will be appreciated.

If you get an 03+ GT motor (maybe 02 also, I forget) you can reuse all your engine covers including the valve covers. You can retain your current return style fuel system and not have any problems. It's basically a straight swap. No problems with the computer.

The Cobra motor is do-able but a lot more involved. I don't know all the details.

When the swap is done, just get a dyno tune and you'll be all set.

The 96-98 Cobra swap is not to bad, especially if you get a complete pull out motor (see them on ebay all the time). When i did mine, the cobra motor still had the wiring harness and accessories on it. Plugged it right into the cars wiring, got chip from modularmadness.com, and fired it up. No problems. If you cant get a complete pullout motor, the GT harness can be altered very easily, mainly just adding a bit of length to a couple of the plugs. Check out cobrapoweredgt.com for more information about the swap. I highly recommend it if you can afford the time and money involved.
