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)

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.

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!

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.

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.

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.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
