1984 E30 323i motor conversion

Hey guys I haven't been on here in ages so firstly I would just like to say hey how are you all and secondly I need a little information I want to rebuild a motor for my e30 and I was thinking of just getting another 2.3L and stroking it and turboing it but after a bit of a hunt around I have found a 325e motor for cheap and I'm thinking of doing the same to the 325e motor what I need to know is if this is a good motor to stroke and turbo or should I just keep looking for another 323 also if I do get the 325e motor will I have to change anything else ie wording loom gearbox drive shaft ect? Any information is greatly appreciated thanks guys.

if youre gunna boost, youll have to swap the e head with the 2.5 head and take the manifolds from the 2.5. of course youll want to rebuild the bottom end to make it reliable. you need the ecu and harness from the 2.5 and dont know if the trannies would swap

So the harness for the 323 is different to the 325 and the 325 will bolt in the same as the 323?

Have a look further down on this forum for Nick323 "Project 323 from the ashes"

Nick lives in Namibia and this blog covers 323i conversions quite nicely...obviously for RHD vehicles though!

I am not a Beemer fundi, but have taken a liking to the E30
You can take your 323 and put in a 3.5 crank to get lower CR, as the 2.5l crank has less stroke.
or you go for the 2.7L bottom end and your current head to give you a low enough CR.
I am conservative and would prefer not going above 10 psi with my suggestion.
I would then use the Unichip to tune things.

I do not mind helping you via this thread, as long as you ask specific questions and take it step by step.

Interchangeability

The Beemers are like LEGO, everything just seems to be interchangeable
Just remember to keep your old motor with all ancilliaries until the swap is completed.
You might have to swap certain items (crank trigger) etc.

But work out your pricing carefully first
Just assuming you can buy stuff off ebay and have them work reliably, is not the way it tends to turn out in the end
