Hi there is a rusty 2 door D21 nissan terrano 2.7 non turbo manual floating around where i live and its on the market for what ever he can get for it.
I have a 4 door D21 turbo terrano with an auto gearbox and I am tempted to put an offer in for the manual with the idea of converting mine from auto to manual.
Does anyone have any input regards any major issues this swap would have?
Are the diffs the same ratio? I am assuming that the body shells between the auto models and the manuals would be the same ie all firewall holes would be there for clutch componants etc just plugged and not used with auto models. I am also assuming that the 2door and the 4 door are basically the same car allbeit for the door difference.
Never liked the auto much prefer to drive a manual. And my car has a great engine so I would like to keep it.
Has anyone done the same swap and if so could you share some tips if you have any.
cheers

i havent done it, but have heard theres a fair bit of work involved. also thinking about it though.

It cant be that hard ive just gone the other way after destroying my 4th 5speed.
You will need the under bonnet wireing harness as they are different to the auto.
you will also need the swinging peddles and a clutch master with the nessary pipe work and the slave cylinder along with the front carpet so you have the gear lever boot cover and just may be the speedo inner and outter cable.
If you go ahead with the swap i would be keen on getting your auto.

I have done the auto to manual swap on my 95 D21 Terrano.The hardest part was changing the pedal box as it has to fit around the steering column.I unbolted the brackets holding the steering column to lower it but it is still difficult.The driveshafts are different lengths as the rear driveshaft is longer and the front one is shorter.The difference is about 30mm due to the manual box being shorter than the auto.I just used manual driveshafts.The gearbox cross member is different and I just used a manual one.There was a blanking plate on the firewall covering the hole for the clutch master cylinder so that was just removed the the master cylinder bolted in easily.The only change in the wiring was to link 2 pins on a 2 pin plug in the engine bay which were part of the starter inhibitor wiring for the auto box.I still have the separate computer and wiring for the auto box installed only because there was no reason to remove it.I haven't compared what the diff ratios are but my truck is doing about 2700rpm at 100kmh in 5th.

I used a gearbox and transfer case out of a D21 ute and the transfer box lever from the ute was a different shape and fouled on the opening in the gearbox tunnel so I had to swap the one from the transfer box behind the auto.My truck has electronic speedo sensor which was a straight swap with the mechanical sensor.

My auto had no reverse which is why I did the swap but the truck goes heaps better with the manual.
I installed my gearbox in my driveway which I don't recommend as they are bloody heavy.Do it on a hoist.
