1. there were no aus spec rb20s

2. ceramic and ball bearing have nothing to do with each other. ceramic means the rear wheel is ceramic, ball bearing means it uses a ball bearing on the shaft and not a bush bearing.

go ask any import place and they will tell you that most rb20, rb25, vg30 etc turbos are ball bearing, and they might show you the difference between the ball bearing and non ball bearing ones.

ok, just took the turbo out, its in PERFECT condition.

tiny bit of play in and out (normal) no play side to side.

1 bolt is snapped off in the exhaust flange though, but it would be easy to drill out anyway.

nah mate, theyre ball bearing, ask anyone that actually knows stuff about imports and they will tell you that most rb engines came with ball bearing turbos.

go down to your local import place and ask them if you dont believe me

and personally i dont think that someone that joined 4 days ago should be commenting on stuff like they know everything

i dare you to go open up one of the r32 turbos that you have there (one without the cooling fins between the 2 housings) and i think youll find that they ARE ball bearing.

the bush bearing rb20 turbos have cooling fins between the housings and have a chunkier core.

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
