Stock Turbo : R33 Gtr Vs R34 Gtr, What's The Difference?

[Andrew.Y]

Hi Guys,

I'm new to the GTR ownership and just don't really know what's the difference on the stock turbos between R33 GTR and R34 GTR.

I have also heard the R34 twins got ball bearings. What are ball bearings and what are thrust bearings? Does it make any performance/durability difference?

Much appreciated!

I'd imagine ball bearing units would spool up faster.

Weather they made the same power or more/less would depend on other factors, which i'm sure someone much more knowledgeable will fill us in soon

For all intents and purposes - the stock turbos are basically the same.

They are both shit, both ceramic, and if they blow with potentially take the motor with them (usually rear that dies)

BCNR33 is 0.42a/r front compressor and BNR34 is 0.53a/r front compressor

Is there any difference between the stock turbos and the Nur spec 2 roller bearing turbos?

N1's are steel wheeled, NUR might be as well.

If they aren't, then no.

I have just bought a set of Garrett -7s. Now what?

Pop them in a box and mail them to me.

Or you could take your car to mechanic and ask him nicely if he'll please put them on for you. A fee may or may not be involved.

if you like tinkering with cars, set aside half a day,grab the PDF manual and your new copper washers/ gaskets and tools - then enjoy. (has been documented a number of times and there are things to know about...)

otherwise take it to one of the recommended workshops where they will fit (and probably recommend other things as well), then enjoy 1bar without worries. from there is it time to spend on other mods/ equipment

great choice on the R34 mate

Thanks mate. I really think I'm not the man for the job. The car is now at a workshop.

Also what kinda of boost to run on a stock internal with -7? 1? 1.2? 1.5? Any commends really appreciated.

How long is a piece of string!

Depends on engine condition, supporting mods etc.

I'm running 17-18psi nearly maxing out stock fuel system and Airflow meters.

300kw at the rears is what most people get give or take.

[DAN00H]

as Sean said, however I've seen 22psi on a cold night - if you are running stock ECU etc then stay safe and stick around 18psi

Thanks! Can the stock turbos be re-utilized somehow?

Thanks. That's about 1.2 bar.

yep, sell em off.

Door stops are good for stock turbos
