Hi,
I'm after some guidance as to RB20DET oil pump clearance and checking before I put it back on. The engine is being balanced with forged pistons and I will be doing some revs with Motorkhana and Drift.
I can't find anywhere on an overhaul procedure or any kind of checks I can to before putting it back on.
Also someone was saying the drift guys have an oil drain coming from the head as prolonged revs end up with all the oil in the head.
Can someone enlighten me or send me a link to some good / factory information please?
