advice for converting nissan patrol gas to diesel

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.

andy, maybe i can be of help. i also live in south america, uruguay. where are you located? we have converted several jeeps cj6 from gas to the TD42 nissan engine. it is a great engine. i know of people who have engines complete with trans/transfer cases. will cost a bit more than 2000 USD. if i can help please let me know. i'm leaving for new zealand and australia in 3 weeks. see how explorOz is shrinking the world. regards, robert

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.

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
