Differences Between R34 And R33 Turbo

[Abo Bob]

Well I've just pulled the turbo off my GTT which is 7/99 series one and put it next to one from an R33 series one.

First thing is that on the side of the compressor covers the R33 one has 45 v 1 whereas the R34 one has 45 v 4 on it.

The compressor covers appear identical.

Now I know this goes contrary to popular opinion but the R34 compressor wheel appears to be metal just like the R33 one.

On the R33 compressor side outlet there is a 1 cast on the outside and a 3 printed on the inside. On the R34 these are both 2's.

On the exhaust housing on the r33 one is cast 307B 2IU, a bit further round there is an 8.. The equivalent on the R34 one is 527A OP6 and further round a 9.

On the other side of the exhaust housing we have F 2IU (R33) and E OP6 (R34).

One thing that is definitely noticable but a bit hard to measure is that the R34 exhaust housing is bigger than the other one. Also the entry port from the manifold is wider on the R34 by about 1mm or so in both directions.

Anyway, I just thought I'd post this for general information. Perhaps people can add their knowledge to it. Maybe if someone has an R33 series 2 turbo or R32 one off the car in front of them they could post the equivalent details.

Interesting thread.

I will have a look and post up some pictures if I get a chance.

Here is a pic of an R33 Series 2 comp wheel.

Definitely Plastic/Nylon crap, guess thats why its black too, not shiny alloy stuff.

What kind of sound does it make when you tap it with your fingernail?

I had assumed my R34 turbo was plastic/nylon/whatever till I did this and it sounded tinny so I dug out the old one to check and they seem to be the same. They also look the same as the pic you have posted.

Hmm, What does yours say, 45v????

Is this a series one or two?

[choyda]

Yeah, we should link this to the Stock Boost for R34 thread. The R34 compressor wheel is nylon plastic crap and isnt as strong as the 33.

But as I also mentioned, some series 2's came with a steel wheel but, as soon as i find solid evidence, ill post.

[Abo Bob]

It doesn't really matter how strong it is because the exhaust wheel will always **** out first. 12psi all the way:D:D

This is part of the turbo that E-Lu-ShuN took of his R34.

[Abo Bob]

Hmm, it's looking like the other turbo I have is series 2 R33. Can one of you R33 owners look at that link I posted above and tell if the car is series one or two. That's the car this turbo came from.

Anyone want to post a pic of the turbo side on so we can see the size of the exhaust housing?

This 45v1.2.3. thing is weird.

[Col-GTSX]

The 1.2.3.4 thingy is the date or version of turbo....

The R33 usually have 1.2 in series 1

3.4 in the series 2

and the r34 has 3.4

Does all that make sense???

[Abo Bob]

No because we have an R34 (link above) with 45v1 on it.

[benm]

Abo i'm 95% sure that's a SII R33.

* Bonnet lips down over the center grill.

* Headlights (im pretty sure on this part).

* The panel at the rear between the bottom of the boot and the top-middle of the bumper (S1 is a clear plastic from memory).

[Bass Junky]

My R34 Turbo has 45V1 on the compressor

[Maxx]

Series 1, S2, S3 GTT use different turbo

"14411-AA100"

s1 is nylon plastic with single blade

"14411-AA110"

s2 is metal with twin blade, same size as s1

"14411-AB000"

s3 is metal with twin blade, made by garrett instead of nissan, bigger than s2

basicly, If your NEO engine cover W/O RED wording...that's S2 or S3

more detail about difference between s1,2,3 (japanese)
