2wding An Awd R33

[nismad]

Everyone knows the R32 fuse trick to convert to 2WD, but i was reading the R33 service manual and it says;

2WD Setting, Remove air evacuation connector, depress the brake 5 times within 10 seconds after placing ignition to on

then follows by saying remove the front shaft,

just wondering if the 32 uses this air evacuation system and is that why u can just pull a fuse on a 33.

Thanks.

the reason u cant just pull the fuse out in an r33 is because the ATESSA is run eletronically and also with 33s and 34s there is always i think 5% of torque goin to the front wheels. In R32s 100% of torque is goin to the rear wheels until loss of traction or too many gs and also the 32s ATESSA system is run by a motor and oil.

theres lots of threads about this use the search button

hope this helps

I'm new here so treat me gently. How does the attessa system handle different rolling diametres within front rear tyres? does the % torque system take care of the different speeds or do you have to have your tyres whithin a fraction of each other.?

im pretty sure u have to have the same size tyres all round other wise it starts to play up

Best way is to do as described... removing the front drive shafts etc

I've been told you can buy a controller but it'll f**k the plates in the transfer case over time if running 100% RWD mode

As described above, you can't just remove a fuse as it's always sending torque to the front wheels. Kinda sucks doesn't it..... but still, the handling advantages are worth it
