Requesting Some C34 Stagea Turbo Pictures

[Bronx]

hey all, just did a turbo swap on my stagea, stagea Neo OP6 turbo swap with a R34 NEO OP6 turbo.

the r34 turbo has a plasic feeling front wheel (it is also black in colour), also has a flex in it when pushed. was guessing thats the case since people say the front is plastic and rear is ceramic.

now my stagea had a different front compressor wheel. My guess its a alloy wheel as it isnt attracted to my magnet. its heavier and also has no flex in it

so im just trying to research if there was a different front wheel used in the stagea compared to a r34, or possibly if they had a revision of turbos through series 1 and 2 of the R34 skylines......

i dont know what year model the r34 turbo came out of, but my stagea is a 2001 build

so does anyone have pictures of their stagea's turbos?? plastic or metal wheel??? or any info at all??

also as a last note, my turbo is stock, not high flowed.

Maybe post up a pick of your turbo. Does it have any other markings. How many blades does it have and are they twin or single blades?

Mine was just the normal nylon/plastic comp wheel with the ceramic turbine. I have a 99 model.

here are some pictures, i dont know what those random marks on the rear of it are though

[QWK32]

looks like the same style as the steel wheel compressors in the early model R33's before they changed to the nylon/plastic ones. i remember reading that one of the series's of the R34's had a steel wheel compressor, maybe the Stagea did too.

just found it. check out this link

aaah, indeed. well i guess it isnt steel. steel is attracted to magnets right? so alloy? also i didnt know there were 3 series cars. always thought that both r33 and r34 both only had 2 series each. i will see into this some more. also my nylon plastic turbo has twin blades on the front, just like the alloy one

[QWK32]

Yeah the nylon ones do have a second fin but it's not as prominent as the steel ones, you can't really notice it looking down the compressor inlet.

Yes it will be some kind of alloy, I don't know what though. It all depends on the steel as to weather its magnetic or not ie stainless steel isn't magnetic.

I don't think the stagea followed the R34 and had a 3rd series, it's just an R34 thing. Apart from the garret turbo I know the fuel/ign mapping is different on the S3 R34's, I've compared the base maps of the R34s supplied with nistune.

really, r34 had 3 series? wow, but they had a short lifespan, 98-01 right? so one year per series nearly. all i know my compressor housing says 45v3 so makes sense. wonder what the power difference was between the 3 series's, turbo lag and fuel consumption.

[QWK32]

I wouldn't go off the number on the comp housing, I had an old r33 turbo with 45v3 stamped on it.

here are some pictures, i dont know what those random marks on the rear of it are though

The marks are where material has been removed to balance the impeller.

There is nothing per se wrong with a composite material impeller; it's cheap to manufacture, nice & light, which would aid response, and it's unlikely to destroy the housing or the engine if the centre bearing fails.

The only time it might be an issue, would be if you were to grossly overspeed the assembly, but I'd expect the ceramic exhaust turbine would fail first.

when i had my turbo out it had a black compressor wheel

pretty sure thats the nylon front wheel that all s2's and r34's should have

yours have have had a turbo swap at some point in its life

[wolverine]

I believe there is also a metal comp wheel on some OP6 turbos.

They are not magnetic so don't worry about that.

[Bronx]

yeah, i havnt had a turbo swap on my car, 100% sure on that, that thing was sooo rusted into the manifold, sure it was stock.

im guessing that 2000 onwards or late 2000 models had a steel wheel. I was pretty surprised when i found out should have swapped front wheels on the turbo, now im scared that plastic thing is gonna blow off. im running 13psi, might need to turn down now.

[QWK32]

Should be alright, I ran mine stocker on 13psi, although only for about 6months until I upgraded it. I also ran a plastic wheeled R33 turbo at 14psi on my R32 for years without it failing.

I'll have a look on Nissan fast later and see what turbo part numbers I can find. But I reakon they followed the r34 and went to steel wheel in the late models.

[QWK32]

had a look in Nissan Fast

it lists 14411-AA100, the plastic wheel one, on all stagea's 08/98 and up. so all S2's. it does however list the 14411-AA110, the steel wheel one, as an alternative part number.

also a bit of useless info, in my version of fast it lists a replacement turbo at ¥120000 = $1516.

[Bronx]

so i wonder how the steel wheels managed to get stuck on the stagea????? maybe had some extra steel wheels floating around and nissan said lets just throw em on random turbos.... bahaha

id rather buy a garrett turbo than spend fkn 1500 on a stock new one......

probably popped when it was newish in japan => warranty replacement or somesuch

John (Appealing ) had his stocker rebuilt here by Grant at Per4manz turbos,9358 6383,mobile 0412361570

he is very happy not sure what it cost him.
