R33 Rb25 Turbo

[benl1981]

Item: R33 Rb25 Turbo

Location: Sydney

Conditon: 2nd Hand - excellent condition. Minimal shaft play

Price: $340 without actuator

Reason for sale: Turbo upgrade, turbo has only just been taken off

Pickup Only unless someone interstate is really desperate.

Other Info: I most likely will need the actuator, hence will be selling minus the actuator. If I can find an Rb20 actuator in the meantime then I will sell it with the actuator. This turbo has the metal compressor wheel not the nylon one which is a bonus.

Great condition, minimal shaft Play. Run at stock boost still last year where it was raised to 9.5psi and made 172rwkw on a conservative dyno. Hasn't seen a track day and I don't drive it hard.

Should be ready for sale by next weekend (just want to check the new turbo works etc before I sell this)

sorry to tell you mate, that is a nylon exhaust wheel .... looks identical to my R34 one .... still a great turbo though

[MANWHORE]

Hi Highcrawler. Nylon is a type of plastic, and it would burn if the exhaust wheel was made of nylon.

Ben's turbo there has a ceramic exhaust wheel, and a steel front wheel - that's what he's saying isn't nylon

well sorry to correct you mate, but all R34 turbos have a nylon exhaust wheel, as do late model R33s, which this is obviously off. Do your homework before correcting people.

[SS#eater]

they have nylon compressor wheels less enertia to get spinning...not the best idea... nylon is a plastic and would melt

thats what i always thought

[Nightcrawler]

100% correct SS Eater - the nylon exhaust wheels are fine for up to 12psi, but any sort of track work over about 10psi will see them shoot down the cat converter.

Awesome for response though, as like you said they have less inertia to spin, which makes for nice early spool up and boost!

[dorifto_sushi]

correct me if im wrong, but dosent standard boost hover around 0.7 bar which is roughly 11lb??

[Nightcrawler]

Nope, I have an aftermarket boost gauge in my R34, and with the stock turbo it showed 7/8psi then up to 10psi (when the 2nd solenoid kicked in at around 5,000rpm).

But once you add exhaust, dump pipe, intake etc, mine went to 10psi/12psi. So yes, you shouldn't be doing hard track days at all if you have the stock turbo, no manual boost control and an exhaust.

not to detract from this sellers thread, theres no way the exhaust wheel is nylon, theyre all ceramic from factory, only thing that changed is the compressor wheel, be it nylon or steel.

[Nightcrawler]

lol .... Google is your friend - there is tons of info about it on the net - plus I have one right here and it is definitely nylon .... it is tuff stuff - but only to 12psi.

All you keyboard warriors need to talk about what you actually know - not what you think you know

You're spot on the money Dead32, RB25DET standard turbo's all have Ceramic exhaust wheels, pre 1995 they had a steel compressor wheel mated to it. But to make it more responsive, from 1995 onward they put a nylon compressor wheel onto the ceramic exhaust wheel.

Nightcrawler, might need to get back on google and do some research into the melting properties of nylon.

[SS#eater]

as i said nylon COMPRESSOR WHEEL not exhaust wheel

[benl1981]

Ceramic turbine exhaust wheel - not nylon. No way would nylon withstand the exhaust gas temps.

ah ok, but the R34 stock turbo I have right here (on my lap) goes a metallic 'ting ting' when I tap the compressor wheel with a spanner, and gives a dull plastic-style 'thud thud' when I tap the exhaust wheel with a spanner. No way it is ceramic - it would make a completely different noise.

And how can by compressor wheel be steel - I was told ALL R34s had nylon wheels. Now I am very confused.

[SS#eater]

its not steel like your cars made of..it incanel or incaneal i can say but spelling it is another thing...its a metal that dosent expand with heat..

[dead32]

like i said no way its nylon exhaust wheel, listen to the 3-4 othe people that have told you your wroung, use google, ive fitted these turbo's and other standard nissan turbo's all been ceramic. now cut the bs and let the seller sell the turbo
