Search the archives.

its the same intercooler as the 3.0 over the engine, still the 4.2, but MAY be direct injection.... Other than that, no real changes.

You would be better off getting a run out model 4.2 non turbo, and getting aftermarket turbo and intercooler installed.. Then it would go lots better than the latest one.

You would come out in front on power and $$..

Hi Andrew, you are right, i spoke to a Nissan dealer today about the new motor, he thinks it will only be an upgrade to get a bit closer to the Cruiser. The new model will have some minor body changes and all new interior, the motor probably only having the intercooler to get the power up. Possibly a new motor with the next up grade. I'm really happy only for the intercooler because if they are going to fit the same type of injector pump to the new 4,2 as they have to the 3 litre, i'll be buying a new cruiser. The 3 litre pump do not have any lubrication from the engine and if you get a load of fuel full of thinners or the like , you can wear the pump out in a few hundred kms. The 3 litre pump relies on the diesel to lubricate the pump, diesel is not really a good lubricant as it is. Some late model 3 litre patrols are already on their second pump and at $6000 a pump i will not be taking the risk with this type of pump. My GU 4.2 litre is nearly four years old and has 240,000ks on it, time for a new one. There is a test in next months 4x4 australia on the new motor, i'll be waiting anxiously for the new model. Regards Michael

Michael, there's no problem with using diesel to lubricate the injection pump - it's been done for years. My 1980 Peugeot has a CAV distributor pump which is lubricated only by diesel and so far has lasted nearly 300,000k without problems and is expected to last a lot longer. Diesel may not be as good a lubricant as oil but it does have lubricating properties and is (theoretically) always clean and fresh.
Stephen.

HI Stephenf, Its the higher pressures that Nissan are squeezing out of the pump and the possibility of getting a load of fuel that is full of fillers that dont have ANY lubricating qualities at all. If you lessen the lubrication and increase the pressures, that where the problems start, Its already happening with many GU 3,0L Diesels. Cheers Michael

New engine is direct injected, intercooled and is electronic and single OHC. Similar outputs to Toyota. Engine has been available in Europe for 2 years. I would hang off and get this mill.

Nissan are holding their cards very close on this for some reason and are playing it down as a simple intercooler bolt-on to the current 4.2. No talk about interior changes, direct injection, electronics etc. Expect a few Kw more and about 380-390 NM of torque... nothing spectacular.. certainly not on par with 100 series LC figures.

if you look at the Nissan web sites in France, Germany, UK etc you will see that the only diesel in those markets it the 3.0 l TD that we get here. same output figures etc. please tell me where you got the info about this 4.2 in europe for 2 years

Info came from the Propietor at Northern 4WD in Melbourne.(he has since moved on). We were doing some dyno tuning experiments with my GU 4.2 and the topic of injector cracking pressures came up. He suggested having them increased to the same pressure as the Europe engine. When I questioned him further on this, that is the info that came out. He then quoted figures direct from a web site that he accessed for some of the tuning data. Now, when and where that engine is popped on to this market is anybody's guess. Nissan are very, very conservative when it comes to marketting something different for them, witness the sales they lost by not going with a 4-speed gearbox back in 1978, and this is only one of many instances where, he who hesitates loses!
