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.

      Is there a shroud around the tailshaft spline into the back of the box? They can rub and make a horrible noise if they are not on straight/damaged. The heat might have caused it to grow too much in one direction and rub.

      Strangely I noticed it either disappear later in the day, or not be present. I definitely noticed when I was crawling around that open wheel thingy entering the pits (that part was audible in car). Driving home and commuting around town for example, I didn't hear it. It's plausible that it was a brake disc or something still slightly in contact. The brakes absolutely felt BAD for the first couple of sessions, huge amounts of shudder and grinding as they got up to temp - And then I actually just forgot about it as the day went on/didn't notice it. The videos were from the morning when this was more present than the afternoon/drive home when it wasn't. I've asked around and got a variety of responses including handbrake shoe contacting hub, CV joints, CB tailshaft bearing as above, and clutch input bearing. I didn't test if it disappeared when clutch was in. I haven't noticed it in any of the other videos nor did I notice it when driving to that extent. More or less hoping the microphone at the rear license plate giving some kind of clue of 'something' but it looks like "spin stuff and see if you can notice it" is the way forward here. I could be smart and use the gopro mic and re-mount it to that location to see if the sound is still present at low speed actually. Sounds like a decent test whenver I have the CBF'ness to drive the car again. Given it's almost 40C for the day of the track day and the next 3 days after, the CBF is high. All I've done since getting home is unpack the car, remove the remnants of the lip and undertray and left it there. I was surprised how well the PMU Club Racers actually worked. The brake performance on the track was absolutely fantastic, best I've ever personally used, no fade whatsoever and the bitiness was almost too good, I was scrubbing more speed off than I needed to, but I also ended up infield when I started trying to scrape off ... less speed.... so...

      R34 GTT idle problem

      Not really, no. Anything you would do is easily reversible.

      I would like more noise related info for my truly uneducated guess  Does it do it at idle or when revving, clutch engaged, and disengaged? Does it only do it when the car is moving? I've heard "similar" noises from a clutch pack that left the chat room, and CV joints that have chewed themselves out But as Matt said, how's the yokes, tailshaft and centre bearing going after their last little issue Fingers crossed it is something simple  Weird noises make me cringe

      One other question, is there a chance that changing the idle speed can lead you down a rabbit hole and is the reason the tuner didn't touch it? Reason I ask is because if that's the reason the tuner avoided it then I probably shouldn't be touching it lol.
