E30 Zone

Just recently purchased a 1989 E30 2.5 converted to 2.7
Bit of a project but ultimately pretty clean.

Need advice on modifications such as a new exhaust system, ECU and differential options.
Thanks.

A lot will depend on how it has been converted to 2.7. What pistons, what length rods, what head and what compression ratio.

If you are looking at modifying the ECU you will need to know these first.

welcome to the zone,

if you know it get the full spec up as there's so many ways of building a 2.7.

Thanks for the welcome.

I’m new to E30’s and working on cars overall but I know it has 325i pistons and 325i cylinder head, I’m still getting information on the conversion as I wasn’t aware when i purchased the car there were so many different conversion methods.
