Dumb Question

[toffy]

ive got a rb20 turbo thats ball bearing, its definately a rb20 turbo as i also have an r34 turbo sitting beside it. im curious as to wtf its off though as i always thought the rb20 turbo was bush type . can anyone help?

hymm i figured all R3X turbos are Ball Bearing. AFAIK.

But i can be wrong. The R34 turbo is much better, better trim wheels and so forth.

YOU gona sell the housing to me? LOL.

All the R32 onwards turbos are ball bearing. I'm fairly sure the NICS engines have bush bearing and some of the ceffys.

R34 has bigger wheels and bigger turbine housing. Compressor of R34 turbo is the same as R33 S2. Fairly sure turbine is the same aswell.

yah the only real diff between 33 (s2) and 34 turbo is one has a plastic comp wheel the other a steel

so its normal to be ball bearing(r32 turb), thanks for that

Nope, R33 S1 has alloy compressor wheel, R33 S2 has nylon and it is the same as the R34 compressor. Blades are oriented the same as the R34 one, same wheel. R33 S1 has blade oriented differently

nope, 33 s1 has alloy yep, 33 s2 has nylon yep , 34 definately either alloy or steel. i put a s2 turbo on my old 32 (hence why i have a 32 turbo lying around), i bought a 34 turbo before i bought the 33 turbo to put on the 32 but was shafted as the 34 turbo was missing the exh wheel and a friend of mine pulled their s1 turbo off their 33 to get it high flowed or whatever so we had all three together at the one time. all three comp wheels are different

Hmm, I posted this topic in forced induction a while ago and the conclusion was that R34 had the same compressor as R33 S2. I also had Cubes send me some photos of an R34 turbo and it looked identical to my R33 S2 and everyone is very certain that R34 compressor is nylon like R33 S2. Happy to be corrected if it's not true, but we'll have to pass the message onto a lot of other people too

i can send you the core if you want lol, ill take a pic and post it up

look forward to seeing it.

Seems like it may be like how there is no real pattern for the codes on the compressor housing...
