I have and excelent nissan sgl 96 with tb42 gasoline engine. Cause the price of gasoline i want and advice about wich engine will fit, easy and will work better fot my sw. I have 2 options, a td27 or a td42 diesel engines. The gearbox will fit? The ratio will be ok. I dont want to change the gearbox nither the cluth. My SW is only 86k ml and is mint.
The other option is to convert the sw to dual LPG/gasoline, how is that

A gas conversion would have to be a cheaper option. The amount it would cost to convert to a 4.2D would take years to pay for itself. Probably better off selling and buying a diesel powered vehicle to begin with.

There is a popular conversion in Australia for Patrols, using a Chev 6.5 litre V8 diesel. No need for a turbo and it will have heaps of torque.
You may be able to source a Chev motor even cheaper over there and you may be able to get the adaptor parts from over here (Marks Adaptors).
Good luck

The TB42 and TD42 is not a straight swap over. and the 2.7 would be the same. in a shorty, I would think it would be ok though, as 2.8 GU donks go well in them. But why wouldnt you go with an injected 350 chev!

Wiring is all different, gearbox bell housings are different, and a gfew more.

If you can get all the wiring and gearbox etc then it would be ok.. other than that, LPG is not good on TB42's they have a common issue with heads failing on LPG. The fix can be done with a rebuild on the head for $1000ish aussie money.

HTH.

Hi robert
I actualy live in Colombia where the gas price is being incresing montly
Do you convert a gasoline Nissan patrol to diesel? In uruguay exist the SGL model (petrol engine with carburator?).
A few days ago a drew a 2door patrol with the convertion. A guy installed a 27td nissan engine. But this will work for long term? This TD27 engine is inoff for de 4 door in a mountain land like my country?

The TD27 is out of the pathfinder / Terrano. the electrics are different and the motor will be under powered . find a TD 28 or thew td 42. You would be better off sticking to the TD42.

Why are you so keen to keep your clutch?
The bellhousings and other bits are different on the 2 engines (TB and TD)

Hi andy2204,

Well putting it on gas would be the cheapest, easiest and the least amount of time off the road. If your worried about problems with the head then take it off, get the nesessary work done so it will like the gas(maybe even a port and polish and get a lil more power/economy).

If you really want to go diesel then there about 7,352 3L diesel engines that were formally living in the new (series 2) patrols! and i bet they are going really cheap- thay may need a new piston or 2!

If money is no big object, go the new 4.2 TD & gearbox from a patrol
