Hi all,

I thinking of carrying out a automatic transmission to manual transmission conversion,  using the automatic ecus but rewiring the neutral switch to clutch switch, reverse switch and speed sensor.

Will this work?

Thanks.

Maybe, you probably need to leave the auto TCU in place so the ECU doesn't through a huge hissy.

However, the ECU wiring will be the least of your hassles, search for threads from others that have done it, it is a huge job.. just sell your auto and buy a manual V35!

It’s very easy I did it in a 250gt!! 

Get the gearbox, pedals, clutch slave and tail shaft and bolt it all in and wire the neutral by pass up and all good. 

Did a mix and match between the coupe and the original tail shaft, split in the middle and then had the rear holes drilled to suit the diff as the 250gt has a smaller diff than the 350gt and had it balanced. 

Yes you will get a auto warning light on the dash.

I thought relocating the park brake was one of the difficult tasks, with some people cutting and welding part of the tunnel from a manual to get all the hand operated park brake to function properly?

have a read through this -

was a CVT, but most things will be similar, somethings will be more difficult as some of the transmission mounts for the CVT were the same as the 6MT, but not the same as the conventional auto.

cheers, that was a good read!   My biggest problem is I just can't find any parts/any breaking in the uk, I know some parts can be used from the 350Z but it's the drive shalf, hand brake and trim which is a problem.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
