Nissan Patrol ZD30 NADS KIT- fitted but still blew up ?

I have only just purchased it, 6 weeks ago had no idea about this problem engine, hen a mate told me about it.

So I have been researching it and decided okay, put the whole NADS system in ASAP. But, then I saw an advert for one for sale spare parts on Ebay with the full NADS kit that had blown up. So now I wondering how often they blow up even with the kits on them.

Surely, controlling the Boost makes this NIGHTMARE end?

I really like the car but hate the idea of going anywhere in this car even slightly remote (which was the reason i bought it).

Check out patrol4x4.com then as there is a vast vast vast amount of information and experience on there in regards to the issue.

How many km's has yours done?

They have been known to go with as little as 60k km on the clock. The NADS gear is easy enough to fit in your drive way at home, and gives you a good idea of what is going on, but yeah even then you won't know what the car has done up until now, and how much damage could have already been caused.

The other flip side to it is that there really is only a small % of ZD30's that do actually go. But like everything a few bad ones earn everyone else a bad rap.

Do the research on P4x4 and probably try to avoid buying a "NADS kit" off of ebay, or some stores, as they are generally over priced for what you can buy things individually for. Some are a lot over priced for the convenience!

she has done 287000, but there is no log book or history so I have no idea of what she has done or what has been done to her. She seems to run great but that is what everyone says until bang.

Which parts did you have fitted?

Did you have the dawes needle vavle ?
The catch can?
blanking plate?

I had a catch can, dawes and needle, but hadn't blanked the inlet off, and hadn't had a chance to fit an EGT gauge.

I have just purchased

Catch Can
Blanking plate
Daws needle (manual boost control)
Pyro Gauge
Boost Gauge

I am also going to have the manifold cleaned & the injectors does anyone know a good how to do with this photos etc...

Big week ahead sharp learning curve

Once get enough cash i will do the Intercooler

Have you got a Dawes and a Needle valve? You need both otherwise it wont help the problem.

I've seen guys use two Dawes valves which has helped to control boost even further through the range.

Was there any warning signs ?

Did yours over boost ?

Did it overheat ?

Do you know exactually, where it went wrong?

I bought this one

It seemed like a good one?

Yep that kit will do the job. You can install the needle and dawes valve in less than an hour if you follow the diagrams that are available online. Search for the ones created by Chaz as they are the easiest to follow.

Once installed it is just a matter of fine tuning as you drive for the first week or so, but you will notice a difference to the way that the car drives as it works through the rev ranges once you have got the boost at the right level.

If you change the engine is it mandatory to change the engine bay plates?

And is there another place where the engine number is displayed on the engine?

Not sure about cars, but the motorbikes used to stamp the vin on the engine block.
