Hi out there,

Fairly new to this but in need of some assistance.

My R33 4wd doesn't seem to be engaging the front wheels aka the car drives like a rwd car should. All spin no traction no real pull forward. I have bleed the system in the rear following instructions from this site and all that seems to be working fine. All that seems to be in working order.

I have had the car off the ground and selected a gear and all 4 wheels turn. But give it a bit of curry on the road and no grip, rears just light up.

I have had someone suggest the transfer case might have finally given up and the clutches within are slipping. Is there anything else I can check to help fault find the problem? No lights flash up on the dash, but I haven't looked in the boot to see to see if ecu has any flashes.

Any help would be appreciated, basically car drives like the prop shaft is out.

Realistically seeing as you haven't got a clue,you won't be fixing it yourself.

Take it to someone experienced with gtrs.

Give them money.

Pick up car in working condition.

Boost off into the sunset.

Wait for next problem to arise.

Repeat.

It is easier to play dumb and see if someone who has had a similar problem arise can shed light on the situation. There are no faults appearing in attesa ecu, the pumps work fine and are pressurizing, there is new fluid in system and is bleed correctly. The tires are great and never had a problem before, same with suspension. Car has run 11.2 @ 124mph on exact same set up. When the car is in the air all 4 wheels drive, but on the road drop the clutch and watch only the rears light up. As far as I am aware from everything I have read on here I have tried to eliminate most of the problems. Yet I am not sure as how to test transfer case and know that it is the multi clutch system inside that is letting it down. I was just chasing ideas that I may have missed by people adding suggestions. My main suspicion was the transfer case but wanted any light shed before I put the car on the hoist and remove the box.

      Dragging some reo behind a ute or trailer will smooth out a dirt road, I've used reo a few times to do unsealed road maintenance when we didn't have any plant available  It's best done when the dirt is wet though, and then you just let it dry out for a day to harden up For wetting the dirt I've used some 44 gal drums in a ute or trailer, and a water pump connected to a hose with a old sprinkler tied to the reo to wet the material down whilst spreading Basically just drive slowly up and down the road a few times dragging a few sheets of reo wired together with the sprinkler wetting it all down as you go

      I did a motokhana years ago with ??Sydney Sporting Car Club???, it was on a grassy paddock and was heaps of fun, I think it was north west Sydney IIRC The old R33 boat was covered in grass and dirt, but nothing that a good wash and detail didn't fix And thinking back, when SAU did the airstrip run in Goulburn years ago, where the old 33 won highest RWD MPH, the quickest RWD ET on the airstrip, and best paint IIRC (before the runs down the airstrip) the damage to the rear quarters from stones flicking up required them the get a respray  I would definitely do a grass motokhana again in the MX5 Who knows someone that owns a farm with a big empty paddock  Liability these days is a big issue though

      No intention of driving the car the way it's set up now, just wanting to make sure I haven't made any mistakes along the way so that the tune can go smoothly, I don't want to waste anyone's time with stupid issues. And of course I intend to get it towed to the dyno in a completed state 😅 I have the base fuel pressure with the vacuum disconnected set at about 40psi, which I believe is at least relatively close to stock fuel pressure, maybe I'll have a fiddle with the reg and see what happens. For all I know I could be wasting my time with this and I should just plumb it in and see what the tuner reckons. I just find it a bit strange that it seems to be under so much load just free revving, but maybe that's just a result of the turbo slowing down the exhaust gasses and making a restriction in the flow, with no boost to compensate.

      The boy just hit up google translate and it worked a treat, he said step one was "please urinate with precision and elegance", he then sent me the correct translation  I get some new loctite for the small fixtures tomorrow and get some "dort" going after that 🤣

      Right, so is the fuel pressure the same as it was previously? If not, well, it's not going to work well. I can understand the theory I assume you are going for, which is: "Run it N/A, and if I have the original AFM, and same amount of fuel and intake air as previously, the fact there's a turbo in my exhaust should still make it run" Which it... might? Provided you don't actually change how much air or fuel is going into the car.. or getting out. But if you have changed that, all bets are off. What is the purpose to even have the car run this way? To get it to a tuner? And if the goal is to limp it to a tuner, you're still going to what - plumb up a whole intercooler system and new intake in the parking lot out front before your tune......?
