I need some advice.. this is a bit of a story so bear with me...
Ok where to start... my ‘daily’ driver is the e28 m535i, dogleg box. It my usual car and basically use it for stomping up and down the a2 in kent a couple of times a week. The rest of the week it just sits around.
have got a better cam on it and a few other bits and bobs so it goes pretty well, occasionally getting a track outing which mostly goes well. My approach mostly being, drive it like you stole it, break it, fix it again but upgrade if you can.
i am lucky enough to have an e9 I am doing up. It’s a csl which I have had for years and clearly now they are going up in value. With the e9 whilst not a stickler for originality, I don’t want to do anything which cannot be ‘undone’ I had intended to get the E9 engine rebuilt and put a different cam maybe pistons, possibly triple Weber’s. In effect period stuff.
here’s the quandary.
Having thought about it and with one eye on cash, I am thinking of putting the e28 m535 engine and box into the e9 and then maybe putting a e39 m54 into the e28
basically I have been quoted 6000 to ‘sort’ the e9 engine into something good power wise but I sort of have it already in my e28...
it it also means I get a six speed box in the e28 for up and down motorway....
views appreciated, would I be fecking up both cars ?
