GUYS, JUST WANNA CLEAR UP AN ISSUE IN RELATION TO TURBINE WHEELS IN THE R34 GTR VSPEC TURBOS.....ARE THEY STEEL OR CERAMIC?

Had conflicting info ...some people say steel...HPI articles say steel......others say ceramic.....maybe different examples support different turbine wheels?

I've searched trying to find an answer to this question as well because i've got the same turbos, but from everything i've been able to find the general consensus is that the wheels are ceramic.

Yeah, I put this question to a few turbo workshops and some said to be sure...the dump pipes from the turbos be removed to inspect the wheels....fancy doing that!

Exhaust wheel is ceramic on standard or V-spec, as demonstrated when one disintegrated in my RB25DETT track car. Now have 25psi compression in 1,2,3 and 150 in 4,5,6. Boost was 5psi at time of failure. They can let go at any time without warning but usually just after being refitted.

R34 N1's use inconel which we use in the aerospace industry in axial flow turbines.

yes, trust me when i say listen to the people on here (like geoff) who have had first hand experience. standard R34 GTR or standard R34 Vspec or VspecII all have turbos with ceramic turbines.

      Wheel refurb?

      By PranK · Posted

      Yeah this confirms what I was thinking. Volks are worth a crap load more than my M Sport 17s and 2500 is nuts!  240 is crazy cheap, was this 20 years ago? I have a fairly good air compressor so I'm tempted to get an eBay sand blaster.

      I got a quote to restore a set of Volk racing gtc wheels at a wheel restoration shop which involved repainting the centres fixing some small gutter rash and repolishing them and the quote was $2.5k I ended up getting them sandblasted and powdercoated for $240

      By PranK · Posted

      Has anybody had their wheels refurbished? I reckon it's likely bloody expensive. Even a sand blasting quote for my 17s was 200-300 per wheel! The E39 wheels are basic BMW M Sport (or M Tech at the time.) they have slight rash and some have signs of bad repair in the past on the lips. The main issue is that they've become really off coloured.  I think it will be too much as this is definitely (supposed to be) a budget resto. I've been looking at others for sale but they all have some minor damage and colour issues.  In the end I think I'll just need to sand blast them myself and do a respray.
