hi all, thought i would give you'all an update on the conversion, i have someone whos going to do it(thanks chris!) got a couple of little questions for ya all.
whats the difference between the pre facelift engines and the facelift engines> is it just the compression?

would it be worth my while(cos the engines out) getting some odds and ends done to it(bear in mind its done over 100k)

HJi mate , i have an 86 325i myself buut not having owned or driven a later type i cant comment on performance ide.Apart from the comprehsion im pretty sure the pistons are a different shape.There is also an extra sensor
near the thrmostat,white one which maybe a cold start aid.Plus the TPS has a different shaped electrical connector,its rectangular as opposed to the round shaped later ones.As thet say ,pretty sure someone far more knowledgeable will be along soon.Are you doing the 2.7 conversion?
