Hy buys just found out my r33 series 2 turbo is blowing smoke and I have a choice of rebuilding the stock one or rebuilding a stock gtr turbo ( which I would think would be better??)

Any way I'm after some info on prices and brands or people who do it thank kind of stuff

I'm moving to canberra in 10 days and I want to try and get it done there

I also thought if I get the gtr turbo rebuild I don't have to take my car of the road at all but to swap it over once rebuilt

Do gtr turbos bolt to a standard rb25det exhaust manifold?

Or is it just not worth it??

Simply not worth the effort.

People have tried - most say they wouldn't do it again simply due to the stuffing around.

Adaptor plates need to be made, the whole intake/exhaust side. All for what? Two turbos that have ceramic wheels - if they fail bye bye motor.

It'll be a min $5000 job as you'd put two proper turbos on ($2500). That's just before you start.

i might just get mine rebuilt i think or maybe upgrade to a r34 turbo i have all the normal mods fmic turbo back exhasue boost controller and upgraded pump i was hoping to get mine rebulit or just a small upgrade to a r34 turbo do r43 turbos bolt up? and are they much better then the t3 standerd turbo

Getting back to your original comment that your turbo is blowing smoke. I have no idea how you have reached this conclusion but I would stop yourself from buying anything until this is diagnosed correctly. There is no point replacing parts until you know what actually needs replacing.

Describe the conditions under which you see smoke.

iv had the turbo looked at by my mechanic and he said that there is shaft play and the bearing have gone and you can even hear the noise the bearing are making :( sounds like when you pop a bearing in a skate board

Is it still making boost? When can you hear the bearing noise?

I have read so many threads like this over the years and stock turbos are either working or the turbine has gone down the cat.

If you want to upgrade you really need to take the time to search SAU as there are so many threads devoted to upgrading turbos.

Try searching with 'hiflow' 'hypergear' 'gcg' as a starting points if you are determined to replace the turbo. The R34 turbo isn't much of an upgrade btw.

Im still pretty new on this site, let me answer this one lol

Option 1 - upgraded turbo = Tune, do u have a aftermarket ecu, if not ur up for about $5000+ (new turbo, ecu and tune)

Option 2 - rebuild stock turbo $800 approx ?

Option 3 - second hand stock turbo in good cond $400 approx.

How'd i do ?

chirs that kinda goes with everything i have read about and im not really up for a hi=flowed as its just my day to day car and i was thinking a r34 turbo would be a little better then the stock r33 turbo but wont hurt the bank to much

Id prob forget the R34 turbo idea, Get urs rebuilt, add a manual boost controller, Its easy, theres a DIY guide on this site. Run 8-10 psi and enjoy the extra lil bit of power. Then u wont need to worry about another turbo for a long time unless u wanna upgrade

and you can hear the nosie the most when its boosting

That noise could be anything from a intake leak to turbo/manifold gasket leak.

Perhaps you should (or your mechanic) should thoroughly inspect for this first before you spend money changing turbos.

Once again the R34 turbo has a slightly larger turbine and will make almost no difference on a stock car at stock boost with a stock ecu.

The problem as I see it is that paying to get an R33 turbo rebuilt to standardish specs (but obviously not ceramic spec) will cost almost as much as a Hypergear hiflow. Now that seems like a silly idea. To spend that much I'd want to come out with the hiflow at least. So the alternative comes down to buying a secondhandy. Now, an R34 turbo will cost a little more than an R33 one, but can be up to several years younger and is a slight upgrade. So to me, it kaes sense to use one of those rather than an R33 turbo, unless you happen to fall backwards onto a really good R33 one for not much coin.

    • Hi all,   long time listener, first time caller   i was wondering if anyone can help me identify a transistor on the climate control unit board that decided to fry itself   I've circled it in the attached photo   any help would be appreciated
    • I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!
    • I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
    • The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.
    • No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
