Welcome from Nottingham. What model zed is it. If its a 2.8 then you could always do the manifold mod
to the forum from West Cumbria.
PM @Tommy Bates who has just completed upgrading his drift car and done a smokin' good job judging by the videos he's posted. Check them out!! And welcome from the middle of Canada JIM
It's the baby 1.9 easiest model to get
Lacks power but want an easy swap 2.8 looks a lot of work and hard to find plenty or donor 323 and 523 cars around here and I've been offered a 2.2 with ecu and key cheap

Can anyone tell me if I fit 2.2 engine and box with ecu from donor z3 if I can reuse my origional 1.9 diff and prop and if all the control units inside car will still function ?

Hi myron welcome from me in Hertfordshire. Can't answer your question but I'm sure someone on here will be able to throw some light on it. Rha, Roy.

Hi, I know @bertiejaffa researched outing a six shooter into a 1.9. Maybe he can shed some light on this for us?? JIM

Welcome buddy
If your looking at engine swaps you need to look for engines out of e36 3 series as the 5 series has a different sump and won't fit
Also you need to find out if your car is EWS 2 or EWS 3 and you will need a ecu with deleted EWS but it will need to match the ews you have on your car and then you will need it deleting on the car aswell , this is a case of joining 2 wires (EWS is bmws immobiliser system) EWS 3 is abit of a pain in the arse but 2 is simple
As for engine size , don't bother going for a 323 , you won't notice a great deal of difference , go for a 2.8 if you can , or if you have the money spend afew grand on a 3.0/3.2 m3 engine

From sunny DorsetCheers Tommy I will do the research on the ews first didn't consider the amount of work to do before I can do the swap
