AFAIK Skylines are plentiful in NZ, possibly something like a R32 GTR V spec could be right up your street. The R32 is a car that I have always had a strange attraction to, and proper RWD biased beast (the R32 variant only sent any power to the front once the back starts to slide).
We have a mk3 MX-5 2.0 sport that Stephanie drives each day, it is a lovely little car but requires some extra mods / fettling on top of how they are supplied by Mazda, otherwise they don't really work on British roads. Even then they don't have anything like the traction out of corners of a well set up 944, BUT on the flipside they don't understeer either so can be driven a bit differently. Running costs are very low and reliability top draw on the MX-5 which IMHO is the single biggest attraction.
The mk3 MX-5 is completely opposite to the older cars in that it really isn't that good on bumpy B roads but feels fantastic on fast flowing A roads (well our 2.0 sport with its 17" wheels and optional lowering springs does, not sure about other mk3's).

Skylines are here, but I don't think I'd say they are plentiful, at least in GTR spec; certainly not compared with Imprezas or even Evos. The Skyline is the only Jap coupe that does anything for me, but it doesn''t do a lot. I suspect my next car will be more like an X5 or a Touareg.

Not sure off the top of my head but on mine the pressures are on a sticker on the inside of the fuel flap.

I used to run my Lux with 29F/36R, as in the handbook, or a little less in the rears. Same tyre size, so I'd think the "S" would be the same.
Thanks to you both for your replies.
You are quite right, madrob6. The tyre pressures (29F/36R as Paul said) are shown on a label on the inside of the fuel flap.
It's hard to believe that I could have owned this car for the best part of 4 years without knowing that. I can only think that my attention would have been on the amount to pay shown on the petrol pump instead!
Thanks again,
Andy

That's what the book says. Sounds very high to me, possibly ok on smooth autobahns but not our tarmac. [&:]
From memory, 38psi all 'round.ORIGINAL: sc0tty
Spill the beans please Oli, what PSI are you running? []
I know that the 'recommended' pressures changed from model year to model year, despite the wheels and tyres (and indeed the rest of the car) being the same. I think they are 'recommended' to be at 36psi all 'round on mine ('89 S2), but it responds better to a bit more poundage.

The 1990 onward manuals say 44psi in the rear [] If you pump up to that figure you will notice a very skittish rear end and your tyres will wear out in the middle. The 1989 manual says 36psi all round which is a much better figure in my experience.
944 Register folklore has had many theories about that 44psi figure over the years and the most plausible seems it was amended by Porsche to counteract high speed blow outs on the German Autobahns where this car can sit at 150mph all day long (until the tyres pop - eek! )

They raised the quoted rear tyre pressure to 44 psi suddenly one year while making no changes to the car. The general view is that this change was a backside-covering exercise based on prevention of blowouts at continuous 160 mph runs on the autobahn. For my taste 35 is a lot better. At 44, the car skips about a bit and I believe has poorer traction at 44, plus it is reputed to wear out the crowns of the tyres.
I too put mine up to 44 when I got the car (late Turbo), spent a week thinking "this is a bit grim" and put them back to 35 again with great relief.
RAV's being an early car will have 35 in the book for the rears.

Thanks for the quick replies. I should have seen the number in the petrol flap, i seem to always be filling the car at the moment.
A trip to Shell last night and £40 worth of V-Power showed little/no movement to the petrol gauge.
Lowtimer - i will check the pressures in my tyres tomorrow and set as you have suggested. I have been running 36 rear and 29.5 front but the car feels strange. I will re-check tomorrow and let you know how i get on.
