rb25 turbo compressor..

[predator]

Took a few photos of things tonight. Here is a shot of the compressor off an RB25det turbo (s1). Note the definite steel wheel. I think most people know this by now, but here is a pic if you just want to see for yourself. I know I for one never got to see the inside of my rb25 turbo when I had mine as I never had a reason to. But when things are off its always fun to study them

Note the interesting twin blade compressor design..

and the point of this thread is what exactly? lol

[predator]

erm :Oops: none really.. its a nice photo lot of people don't even know what the stock turbo looks like up close.. lol

[KamikazeR33]

yeah gordo im sure they all have steel front wheels, its the rear wheels that r different

[Nozila]

that turbo wheel looks completely different to the one I have which i noticed when I went to replace my stock dump pipe. It looked plastic instead, definately not steel or as shiny. I have a pic of it at home. Is this because mines a series 2.

[predator]

hmm..interesting.. i thought all the fronts were the same, just rear that was different.. post the pic when u get home

i might post the exhaust side of that one.. definitely ceramic looking.

AFAIK:

* All turbine wheels are ceramic

* Some compressor wheels are metal (aluminium?), some are plastic. Someone else will be able to tell exactly where in the models this change occurred (S1->S2?)

R34 GTT Compressor wheels is made of nylon

...post a picture..

Saw my old turbo apart the other day had a plastic wheel this was on '95 model.

Is there any size difference between the nylon wheel on r33 and r34?

R34 GTT turbo

[cameron]

And a high flow Stock R33 turbo, You can tell its highflowed because of the thin wall on the intake compresser side and on the exhaust side its machiened right out to the edge of the exhaust housing.

Don't mind the bent fins on the intake side, they have scince been replaced with new ones. the bent fins were from thoes crazy japs running the car with out a pod filter.

[predator]

lol.. what a mess.. those crazy japs - never did think that was a great idea for the turbo inlet just direct to air

here is the exhaust side of the one up the top.. ceramic.

[cameron]

Heres the exhaust side of the R34GTT turbo. Apparently that orange colouration is from runing octane booster.

Gordo:

The exhaust side on your turbo looks really clean. You can still see the white balancing marking on the fins. Have you cleaned it or has the turbo hardley been used ?
