ZD30 Di replace with new or reconditioned?

[outback]

Well managed to cook the old ZD30s engine last Saturday. Was a nice 42 deg C for most of the trip, home to Adelaide.

Besides the why's how's etc; simple problem now is I need to replace the motor.

Besides that new viscous clutch for fan, replacing the radiator, the clutch and dual mass flywheel.
Heavy duty clutch and solid flywheel going in.

Also looking at the injector, water pump as well.
Hoses are new so not replacing them as yet.

So big question is do I go for a new ZD30 Di motor with NADS from scratch or think of a reconditioned one again with NADS.

Milage:136,000km.

Apart from the common rail what are the differences between the Di and crd??

Is it worth going a reco crd with nads?

I had thought about that option
The two that springs to mind to cause issues
1. fuel feed pressure
2.ECU.

I am sure there are a few others to make life difficult.

for me it would be down to price and which motor offers
the most warranty, crate or reco??

Identical except the fuel system I believe. Same block. Also the intercooler is a little different and mounted differently.

From some of the prices I have seen, a reco one is not that much less than a new one ..... I have seen prices less than $1k difference.

Not that I don't trust the quality of our engine rebuilders, but if that is still the case, then I would cough up for the new one

The block is the same in the two motors but the head is not. CRD has air intake on opposite side to DI. To change to crd will need the new intercooler, pump, injectors and a new ecu to control it. That is assuming you could use the old loom but not sure. Can you get short motor from Nissan?

Would seem too much of a mess to go CRD.

Short motor from Nissan, sure, when they have some in stock..

At present looks like a new motor via a slow boat from Japan and a long wait.

Seems i will have to drag out the "back up" unit and do the minor repairs and use that. At least that is only belts, fan, batteries and tyres. And petrol!!

A new DI motor from Nissan will incorporate all the upgrades to the zd30 oiling system. I was told that in 2005 they upgraded the oil spraying system under the pistons to help cool them. Made it less grenade prone.

This might be of some help....
