R33 Gts-t Series 2 Turbo - Ball Bearing Centre?

[dwayne293]

Hey all,

just wondering whether the series 2 r33 gts-t centre is ball bearing or bush bearing type? also do they still use a ceramic turbine wheel or is it steel?

thanks

Its ball bearing with a plastic front wheel and a ceramic rear (series 1 has metal front)

[dwayne293]

Plastic compressor wheel? is it really??

[Guilt-Toy]

Yes its plastic. to make boost come on quicker - thats why you cant run as much boost as the s1 turbo.

The core is a ball bearing core but garret are unable to rebuild them - when these turbo's are highflowed they replace the core alltogether. they were designed to be a chuck away turbo - she blows she goes.

plastic? lol sonsofbitches... no wonder i had no front wheel and no rear wheel... i was sure it was ceramic both front and rear.. either way they don't last long

[dwayne293]

Oh that sucks, hopefully the one I just bought is a series 1 then.... I will have a look when I get home and see if the comp wheel is plastic. Are the series 1 turbos still ball bearing type? Any noticable differences?

Thanks again

The front compressor wheel is not 'plastic' it's 'bakelite'.

This gives the turbo faster spool. There is no problem with running more boost on the sII turbos. The front wheel never has a problem.

It is always the rear ceramic wheel that lets go.

Furthermore, once the rear wheel on turbos let go, the front wheel usually loses its balance and will eat the housing.

The bakelite compressor wheel will supposedly also do less damage than a metal compressor wheel.

Lastly, the sII turbos are newer, so are generlaly in better condition.

therefore, in summary, the advantages are: faster spool, newer, less damage.

No disadvantages compared to the sI turbo.

That isnt correct. The ceramic wheel would shit itself long before the compressor wheel fails. Do you have proof or are you just guessing. The wheel is a nylon polymer which can be quite strong.

nah, r33 hvn, that's normal. when the rear wheel lets go, quite often (maybe 50% of the time, the front wheel will shit itself too

Chris, is that your gf? she's really hot

Oh well hopefully should be good. I bought it for an upgrade for my 32 as my stock turbo is on the way out. This one is off a low km series 2 and in very good condition, minimal shaft play, no signs of any oil leaking past the seals.

I am going to swap the actuators over and fit it, hopefully with good results

Are the R33 series 1 turbos ball bearing?

Yep S1 and S2 turbos are both ball bearing
