Airbox ideas please...?

[Patrolling Paddy]

Looking into the same. GQ TD42 a/m turbo and w2a i/c and DieselGas.
Not currently running big power (130kw) but need to upgrade the intake to allow it to give me the best delivery it can on a stock pump as I think it is starving currently. Safari snorkel stock pre filter only and a crappy 3" filter-turbo pipe.
Looking at the patroldocta 4" snorkel and box and wanted your thoughts on if they are worth it?
I will eventually upgrade the pump and full turbo and I/c setup chasing the 200kw mark but baby steps for now.
Is there a better off the shelf setup available?

My first patrol was a 1990 DX 4.2 natural. Fitted a turbo to increase power, kept both the pre cleaner and air cleaner, modified the air cleaner to accept air intake on drivers side and ran a front mounted intercooler. Had almost 1M Kms on it when an oil filter collapsed

I have been told just using the TD42 pre cleaner is not good and also been told that the other more common after market boxes are not what they are cracked up to be.... what are my options for a good airbox??

I am running stock set up until I get it inspected then putting on a turbo.

Hey BA.

While doing some research for parts on my Explorer, I was watching a show called Extreme 4x4 from the US and they just installed one of these Spectre Air Cleaners on a Jeep which has a supper charger installed - http://www.spectreperformance.com/se...specifications

Here is one from ebay that is not a bad price - http://www.ebay.com.au/itm/like/1714...=true&lpid=107

They then added a snokel to the kit.

If a supercharger can handle them then I think the TD42 should be ok.

Just a thought.

Cheers,

Rob

For a mild setup driven daily in an orderly fashion I haven't had an issue with my intake setup, however now I am a bit more demanding it is lacking and feels very asthmatic. 3" just isn't enough for the 4.2 when under stress in my opinion and this is why I am chasing 4". That spectre thing without being rude looks like puss and running a 3" filter is very limiting for this engine.
Have a look at the higher performance TD42s and the size of the filters required to stop the turbo starving.

Your logic is correct. That setup is puss and would even be restrictive in its application. It might be ok if you only ever drive it on the road but with a filter that small as soon as it saw any dust it would become even more restrictive.

There are a couple of good options available now with the likes of 4by fabricatiom, fatz fabricatiom and radius fabrication all doing nice units that are 4" in and out.

If you want to build your own then a good rule to follow is use the least amount of directional changes, use a nice panel filter with a good surface area and each side of the box if possible needs to be the same capacity as the engine so 4.2L.

maybe plumb this back into the cabin, nice clean air

To small. 4" even for a zd30 if you could.

This may be worth looking at

[nissannewby]

Still to small.

[rkinsey]

Still to small.

Why are these too small nissannewby?

3" and 4" inlets and K & N filters will still move the same amount of air as VN commodore airbox would (or anything similar)

If the supercharger on that Jeep can handle it then so could the turbo charger on the TD42. I don't see any restrictions here myself.

Like I said, Just a thought.
