How To Make 32Gtr Run Awd Directly?

Hello everyone,

just a pondering question, is it possible to make 32r running 4wd all the time without using the current electronic control system. In other word I want to cancel all sensors and ecu and make it run awd permanently without headache .

Is it possible to cancel actuator from gear box and weld nut to press on clutches or keep then in engaged position all the time.

The pump unit isn't deisgned for continuous duty, but you mentioned getting rid of all that.

The transfer case clutch pack setup, if locked permanently would either:

suffer from 'wind up', if used on tarmac, as there can be slight differences in driveline rotation front to rear, and that will break stuff.

you will have mad understeer due to the constant locked 4wd mode!!!

The only way to do it properly would be to change the transfer case to a center diff arrangement as used in the subaru's and evo lancers....

Yes you can do it, no it's not a wise move. Not only will you reduce the hp driven to the wheels to give you acceleration, but you will destroy the transfer case from binding the clutchpacks too much

This + the BSM GTR tore the front diff off the sump running 50-50 4wd

they did find they were quicker on the track though (IIRC)

Locking the transfer is no drama, BSM did it with a solid transfer. I also did a similar thing with a machined shaft.

However both cars I know ended up with front diffs sprawled all over the circuit.

The speed gains were negligible. We found the only gain was in top speeds reached on the straights as exit acceleration was slightly faster. Entry and mid corner speed was actually slightly slower.

      I drive the Tiguan much harder than the Skyline in all conditions, because it just grips and hooks, unlike the R33 shit box

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
