nick, the guy who had it years ago dropped in a L24e from a series 2 MR30 skyline
his username was 'Neg'
the sump comes standard with a flat section on the side for an oil return to be welded on
the water line part is likely the part that heats up the idle control valve or throttlebody
unfortunatlryeh its just a stocko L24e, but the head has been recoed a while back, new gaskets etc
the rings are the buggered part...
the reason it kept popping was the microtech fuel only ecu was what was contolling well only fuel... not ignition at all!, the dizzy didnt retard timing on boost, so ping ping away
I will use the stock L20et gear, which is the 1st Nissan ECCS 'JECS' ecu setup, that does change timing, and fuel etc (but i will be useing the microtech as a piggyback for the minute)
