zd30 air box to gq with v8 conversion
zd30 air box to gq with v8 conversion
when fitting zd30 airbox to Gq tb42 with v8 conversion, how is the box secured & where do you put the charcoal canister.
if your planning to run anything much more than a stock v8 i wouldnt use a holden airbox, i have a gq with a holden v8, it has been stroked nothing radical tho and the airbox is too restrictive. so im in the process of looking for a more suitable setup up to give me the flow i need, i also want to run a snorkel.

I'd be interested in why not too. I'm not going looking for it, but i'm certain i've seen +150rwkw TD42T's running these boxes, and albeit 800cc smaller in displacement, diesels need to flow quite a lot more than a petrol.Quadcamshorty wrote:still interested, why not use the zd30 airbox??
If someone wants to do the maths, a typical hypo TD42T runs up to about 4000RPM, between 15 and 30psi.
I've just got a ZD30 unit to use on my 4.8. There are mods to get them to flow better. If the plumbing for the ZD30 unit and the 4.8 are similar sizes from the factory, why wouldn't it be adequate? Sure, it may not flow enough at higher revs, but I'll deal with that when I can confirm it's too small.
And yes, diesels need more air, so I am guessing that a 4.2 diesel and 4.8 petrol have similar airflow needs. And since the ZD30 one flows more than the 4.2 one, I must be close to the mark.

would tend to agree on this one, even though i just fitted up a zd30 airbox to my 5.0l.much neater in the gu then the holden air box!brad-chevlux wrote:the stock VS V8 air box flows more air then the ZD30 one, even with the billet top as seen on patrolforum.com
the VT are box is better.
the 5.0l box has a bigger cut out section for breating air although it does suck hot air from the engine bay and the bottom half of the air box is only about 60mm deep which would only allow a small diameter piece of ducting to the outside(snorkle/gaurds) hence why i changed!
after doing the air box and removeing the air con condenser core my truck runs a bit cooler!
there may be other/better ways but i like the way it turned out!

the base of the air box isn't the reason it flows well. the lid is the reason it flows well.simcoe wrote:would tend to agree on this one, even though i just fitted up a zd30 airbox to my 5.0l.much neater in the gu then the holden air box!brad-chevlux wrote:the stock VS V8 air box flows more air then the ZD30 one, even with the billet top as seen on patrolforum.com

the base is the same as the V6 one, but the V6 air box has a square lid and doesn't flow well.
either way, the element is only small and will clog with dust at twice the rate of the VT one. or the ZD30 one.
I was under a 96' model Mitsubishi Canter today, it looked as though the airbox from that would actually flow quite well, 3inch inlet and well radiused 3inch outlet. filters were well priced too.

VN to VS v6 and v8 air boxes all the share the same lower half and filter.coxy321 wrote:Going by the concertina fold count and length, there's a significant difference between a V6 Commodore panel and a ZD30 cylinder filter. Are the V6 Commodore ones similar to the V8 units?
personly i'm not sure about vt onwards. i do know that both the v6 and v8 vt on air boxes are about twice the size of the pre VT ones.
Being that the VT was fitted with both the holden 5L and chev LS engine i'm not sure if there are any differences here.
but the V6 being teh most common would be easier to get.

Had a play today. Canister went next to the dipstick (not me) but remember mine is GU with 4.8. At first it went next to the ABS module. But I am trying to leave that hole vacant for a compressor, otherwise It fits perfect. That's where I had it to start with and it fits real good with the factory mount and hoses.
It is now next to the dipstick and I just need to get a couple of metres of hose to plumb it up. Then I'll get the ZD30 aircleaner and matching coolant bottle and it should all work.
Oh, I also had a VT air cleaner laying about so I had a play with it too. It would fit real nice but not sure on where the battery tray would come to. I don't think it fits with a dual battery setup but hopefully these pics show otherwise.
