try the old throttle body and press reg seperately and together to see if one of those is playing up/ leaking etc? how did it perform before? will defo need some sort of setting up as a standard ecu won't have the right fuel and ign. curves for that spec.

who timed cams up? check that out.

possible air leak somewhere? throttle body sealed properly?

is the oil being burnt? blue smoke? high mileage? not good to tune a tired engine, get it back to it's best before making it better.


rs2k rear beam fits straight on with disks on the rear, will just need the flexi hoses too.
