I have a 96 model and when i bought it recently it had already had the transplant to the 3 litre motor with an aftermarket turbo but they did change the gearbox also. it all seems to fit just fine but i never drove one with the 2.8l but now having this im quite impressed with the power it makes especially as ive come from a v8. i think your choice may come down to money as from the receipts ive seen from my lux its a pricey swap to do.
