About:
Had other e30 316 before this(not as good condition as this but I did regret selling). Now back to e30. Love this car.
My brother owned current car before me.
Both cars came with 1.8l engine with carburator. Once those carbs get into problems it's pointless to keep repairing it.
I have one m10b18 ripped apart & waiting for assemly and EMS.
Current engine on car has minor running issuses due to last breakdown (carb and broken valve rocker). Got deep into engines after that. Swapping current carb engine for M40B18(newer 1.8 engine) for few months until build engine with EMS is ready.
Waiting forward to Jaguar 0.7 release - should happen pretty soon I guess.
Trying get engine running N/A with jaguar first. After that... going for boost.

Good short overview of m10 engines: http://www.fritzsbits.co.uk/shop/engines/

Update:
Ordered Jaguar 0.7. Currently preparing engine for injection and Jaguar.

Injector resistance: 14.5 to 17.5 ohms.
Probably going for hall effect CAS. Will try to use old distributor for that.
