R32.5 Issues

[r325]

Hi all,

Sorry for a bad first post but have just carried out and RB25det spec to conversion on my R32 skyline, the car starts and idles fine........ for 30 seconds, then idles really lumpy and unless accelerator is pressed will stall. Once the engine is warm runs lumpy, and really not keen on going any more the 100Km/h (3k revs) getting very close to taking the engine back out and selling is as parts :) any ideas?

Are you using all the factory sensors and ECU? Do all the sensors work (within factory spec)? Did you do things like remove and clean the injectors before you installed the engine? Have you checked the ignition timing?

hey man, i had the same problem, turned out to have the timing 1 tooth out on exhaust side, double check ya timing belt.

also did u wire the car yourself or did someone else?

and while ur fiddling clean the AAC valve

check cas(crank angle sensor) could be loose or bolted back out of timing
