That said, the car is now being re-stripped and having the entire electrical system re-wired.  We can now remove all items that are required to be road legal, such as intrusion bars, doors, glass, air bags, seat belts and the various computer assisted controls that are no longer required (such as ABS, ATTESA and HICAS).

Maybe I'm being naive, but the idea of a GTR drag car is to use all FOUR wheels to deliver power ?

How would removing attesa be good ? It's just a 2wd GTS then!!

Just look at VL's.If you have sticky enough boot's and good sup setup I guess you don't need ATTESA,it's more weight to move.Also those 1000hp GTR's in japan only in 9's and the VL's are up with them.My 2cents.

What fuse on the GTR R32's?!

I would love to be able to put it into full RWD for a bit... just to see how it handles...  <_<  :lol:

they handle terrible, but spin the wheels ok!!

there really meant to be 4wd and obviously designed like that..

and with regards to the dyno run, they probably pull out the front drive shaft, only 4 bolts underneath the car, to dyno it it. (if its a 33) 32s, just pull the 4wd fuse link.

I would have thought ATESSA would have detected no traction under the rear wheels and engaged the fronts ?

But would there be a lack of traction under the rears? The wheels are still turning the rollers?

The would not be lack of traction at the rear, but the large speed differential between the rotating rear wheels and stationary front wheels would make the ATTESSA system think there is a lack of traction and redistribute the power accordingly. Does that make any sense?

oops, haven't seen the vid. Assumed it was a 32.

You're correct, it is a little harder.

too hard obviously, not difficult to get those transfer cases smoking the clutch packs now is it. just visit gtr specialist workshops B)

yeah u must be far from an expert, the cam shaft control the opening and closing of valves to allow air into and out of the engine, then have nothing to do with ATTESSA

the shaft your are tihnk of may be the front drive shaft which goes from the transfer case to the front diff, yes as is mentioned above can be unbolted.

      So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here

      V37 Radiator removal

      So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.

      Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go

      OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way.
