I didn't do it - but it was such a feat, I think it deserves an honourable mention...my cavalier had bottom-end bearings that started knocking, my mate decided to swap a lump with that of a scrapped car. He found a good donor lump, and decided to replace my 8 valve single point injection for a 16valve multipoint injection model ( more power, and easier to tune the feulling for even more!!! ).
Sadly the wiring loom got cut too short and the multipoint wouldn't work - so he mated the 1.8 head with the 2.0 barrels and bottom end, with a 2.0 camshaft. Doesn't sound like much, but he had so much bother with it that when I offered to source a new loom ( to fit the 2.0 head properly ) he promised to break my arms and dismantle my car to the last nut and bolt, for me to rebuild on my own, if I so much as thought of mentioning that to him again ! :shock: :shock: :shock: :shock: :shock:
