Turbo Rebuild Help!

[wilderboy]

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?

[R31Nismoid]

GTR turbos are not bolt on, so forget that idea.

[wilderboy]

How much modifying would it need?

Or is it just not worth it??

[lilcrash]

Gtr turbo is made to suit 3 cylinders equalling 1.3litres, your rb25 is a 2.5 litre. Just get an atr43 or highflow from hypergear.

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

[wilderboy]

i think a r34 turbo will be the go

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

he said to look around about re-building or upgrading

[wolverine]

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 ?

[wilderboy]

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

[wilderboy]

and you can hear the nosie the most when its boosting

[wilderboy]

and as far as i know its still boosting i dont have any after market gauges so shes kinda stock lol iv only owned her for 6 7 weeks

nd its only running 6 psi

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

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.

[wilderboy]

could the intake leak to turbo/manifold gasket leak cause it to blow smoke?

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.
