IMPORTANT! For all of you installing a non-bb turbo on a bb turbo engine

you will need to take off the banjo bolt that connects the oil supply line to the block and either get one without a restrictor or drill the restrictor out.my rb20 had a restrictor banjo bolt but im going to be running another bb turbo, but it has an internal restrictor so i drilled mine out a touch.if you dont do this the oil will fry because of oil starvation due to the fact that bb turbos need less oil than standard bush turbos.

Thanks Carl! Good info.

Or just run a braided line with a -AN fitting.

Hmm. I have running the stock Banjo fitting off the block and then it goes to a braided stanless line to the turbo.I have been running this way for almost half a year.

on my engine as it sits now i have a good ridge banjo with a 12mm hole and -4an fitting.it then goes to a -4 pushfit hose then to the turbo using a -4an to 7/16" inverted flare adaptor.you still will need to enlarge the stock banjo bolt if you are running a bush turbo unless you can find a 25mm long 12mm banjo with a 1.25 pitch on it.
