Hey guys I have a r33 vspec however the sump I've just extended was from a r34 gtr non vspec. Is it as simple as taking the 34 centre out and swapping it for a 32/33 centre or is there something else I need to look at?

Thanks Ant.

Interesting question....yes in theory all you have to do is swap in the diff centre from the 33.

There was apparently some trouble with fitting the centre into the 34 sump I bought due to clearance to the cover, will be interested to hear how you go.

I could've answered that question but my R34 gtr sump is with Brad from Pro Fab and it doesn't look like I'm getting it back! :(

From all the research I've done, it SHOULD fit.

Part numbers for sump/diff are the same from R32-R34 GTRs.

Same thing for me, you will not have to mod as you are switching from 34 to 32 pinion and center.

I also had to dremel some clearance into a 32sump to fit my 34 diff components (pinion gear).

Gents I'm about to do the same thing where I need to put an R33's diff centre and input spline into an R34 sump / diff housing on my R33 after my sump cracked on me.

So this is straight forward yeah? No clearancing issues that have been mentioned on other forums?

      Block bump. $400. As above cyl 6 needs bore or sleeve.

      I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.

      I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.

      From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.

      They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
