i love you guys

Is it safe to remove the AIVs if you still have cats or will it cause premature cat failure? Meoaw

AIV removal

 

ABS - ask blackmagic

Looking into this one ;)

(easiest option is to make a switchable abs)

hmmm interesting

AIV's are just there for dilution of exhaust gas with air. Wouldn't worry about cooling, it's just an emissions thing.

ABS: should be completely stripping mine out and putting residual pressure valves on this weekend. Will try and remember to get some pics.

...removed the AIV's from my last Z32 (series 1) and cats were still ok 5 years later when I sold it - and bought a Z32 (series 4) and guess what? It has cats but no AIV's... Looks like Nissan gave up on them.

So just to clarify... The AIV's vent air into the exhaust AFTER the cats? and removing them will not harm the cats at all..? Wanna be totaly sure before I go tearing them out and jumping up and down on them!

RIP AIV then. thanks :)

I think that the later series Z's use a 32bit processor in their engine mgt system and it's primarily to aid emissions hence there's no need for the AIVs.

 

But I had MOT's done before removal of the AIVs and after, and there was no difference within the readings. The emissions were always very good, well within the pass spec. So if this is the case, I can't fully accept that the extra capacity (32 from 16 bit) of the management system is only for emissions - it must be a performance mod or fuel eficiency mod too - the series 4 is far quicker than the series 1 (only going on personal experience).

 

Get the valves removed - your car will go faster because of the weight loss.

 

...good luck

thans agaim chaps

 

interested in the residual thingy thing

 

pics weouold be good - and an explanation of what they hell that is lol

 

As i am thick

Residual pressure valves just hold 2psi on each callipar to stop pad knock back. Give more immediate brake response which I think the Z lacks.

If you remove the AIV hardware, do you need a new ECU chip with a mod to remove the AVI fuction?

No M8, just get rid of em!!
