Steps In Fitting R32/33 Rear Sub-frame To A31?

I believe the R32 GTST rear subframe (i.e. diff, axles, hubs and brakes) can bolt up directly to the rear of the A31 but what about other Skyline models. The reason I ask is because a buddy and I have sourced a rear subframe but we're not quite sure exactly which model Skyline it came out of, what we do know however is that it has a LSD as well as 2 pot brakes with "NISSAN" grooved in the calipers and HICAS.

What I want to know is if there are any problems to look out for when attempting to bolt up the entire subframe as a whole. Is it simple as pulling unbolting the old non HICAS, regular 2x3 bolt diff non-lsd sub-frame and bolting in the new one (i.e. no fabrication involved)?

OR

do we have to make adjustments?

I'm new to this so please bear with me.

All help appreciated.

r32 rear sub frame bolts straight in, just get a hi cas lock bar. when i did it the only proplem i encounted was the back brake lines needed to be made longer, only cost $40, and if you unclip the original cefiro flexable brake lines they will strech to reach to get you by. by the time you stuff around doing a back brake conversion it is quicker an easier to swap the whole sub frame, you can sell the old one aswell. but some say one of the bushes wear out. good luck. install pineapple bushes while you do it.

Thanks for the recommendations. About swapping non-hicas rear subframes and doing 5 hole conversions...in my country (Trinidad & Tobago) it is relatively easy to get an entire rear subframes from an older model Skyline (my mechanic has one lying around his yard doing absolutely nothing).

I will go the route of using the R32 rear-subframe and hopefully it should bolt straight up without much hassle.

Again, thanks for the heads up.

      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.

      Ethanol Content Sensor - Always at 11%?

      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.
