RB20 BB turbo
Posted: Sat Apr 21, 2012 7:23 pm
Does anyone want to see some pics of a BB turbo in pieces? (CBF'd, but will if someone is keen).
I bought a 'scraping sound' RB20 turbo for $30 fully knowing it would probably be shagged, pulled it down to find it looks like it has been on the bottom of the ocean for a couple of weeks and has some corrosion on the ball bearings and their races.
Apparently, the turbine wheel/shaft is the same through the ceramic BB core RB/VG family of turbos with just the exy housing being different trims as well as the comp wheels. So, with that in mind, I can bung a RB20 exy housing onto a RB25 combo.
