Gday,

Do you guys think this Isuzu Bighorn air box will flow enough air for a TD42 with an after market turbo?

This Isuzu air box has 20cm of diameter and 20cm + oulet 5cm of length.

I have other option and it's a 1KZ air box, but it seems to be very small...

Here are some pics of them:

And the 1kz if I'm not mistaken:





Any advice is more than welcome !!!

Cheers

Get a GU air box from a 3L they bolt in using original mouting holes.

Hey SIM79,

That's exactly the problem, cause here we don't have a lot of patrols and I can't get a GU air box, if I want to get one, I will have to get it from Nissan and I will have to pay 300 Aust dollars for it

i used the 2.4 box on a 2.8 hilux with a turbo, it was ok for that, using it on a 6 cylinder i believe will be very very restrictive. GU airboxes are even wider than the standard GQ box from what im led to believe.

you could try finding the big cyclonic metal airbox from a late 80's 2.4L Diesel hilux (2L motor).

I reckon they have more flow potential than the standard nissan airboxes.

Mate, its all about AIRFLOW.

I would run whichever one looks better and neater and if it feels restricted, try using a high flow air-filter such as a uni-filter or other.


I used a Hilux airbox and ground the inlet/outlet up to 3" and welded stainless on there (from a 2.4L diesel) and ran it on a 4.2L Worked turbo diesel with no airflow restrictions, even with the standard filter.

So these guys who say it will be very very restricted have not done it. As long as the filter has a big enough surface area and you upgrade the inlet and outlet pipes to the size you need, then you will be sweet.

YEP! They pretty much ran that on all landcruisers up until 2005!

Correct. This one's off a petrol 80 and does fit, just. You will need to move the overflow bottle back towards the firewall.

It has 3" in and 3 1/2" outlet (made an adaptor back down to 3" to fit the turbo inlet).

They got nicer, a nicer drain bung, better paint and finally were made from plastic, but yep, same ring airfilter..

Nice fitup... They provide Plenty of surface area (like the whole filter). They have a great water drain system, The only drama with them is they are MASSIVE!!

Excellent guys thanks a lot for the tip, I will try to get this Hilux air box.

And something else, bj on roids you said that early hilux air boxes were made from plastic, if I get one of those plastic ones, it will have the same dimensions and inlet / oulet size of the metal one?

That fit just nice Mavtd, do you think that the early let's say from the 90's until 2000 petrol hilux air box will have the same dimensions, plus inlet / oulet size as the one you have?

Get one off a Landcruiser marcorti!

Check this thread for other options too:
