Re: engine transplant
Any decent mechanic will have no probs with the conversion. You can also do it all yourself if you have the tools. t5 will bolt up. Wiring is different, but the xr6 engine should come with the wiring and computer.
Physically, the xr6 engine is the same so you will fit it without problems. I dont know much about the bolt ons except the xr6 has a higher capacity alternater and the ac compressor mounts in a slightly differnt place.
