Check out what we CAN'T do...

Not really a matter of what we can because we can't do anything.

Modifications to Motor Vehicles (PDF)

That dosent tell you anything, all it says it you cant fit a bigger motor without telling them, you can get approval to fit a bigger motor though.

The problem is that you would need an inspection and we are not going to fit a bigger motor and leave it stock so ti wouldnt pass.

[Cubes]

Its not that bad really. I did over exagerate.

[Cubes]

So according to the above.. You arn't allowed to modify the pollution gear. Hence Catch can.

Some where else on the site I also saw huge fines for modifying the pollution gear.

[Clint32]

oops i broke the carbon canister thing when i pulled my car apart and forgot to put it back in. May have to find a smaller 33 one to keep out of trouble as well as make a proper oil air seperator.

[Cubes]

So what is classed as a proper oil air seperator one that plugs back in in front of the turbO?!?!

[Clint32]

I think you need a PCV valve in the inlet manifold, so all you can do is take the rocker breathers to a catch tank then filter the air somehow and run a hose to the manifold.

This means that the rocker cover may be under pressure as there is no where for the gas to go other then the manifold, in which it would then need more pressure to vent back in, if you know what i mean. Ive seen a few setup the same so it must be ok.

The oil/air seperator on my r33 plumbs back into the inlet pipe just after the AFM - which is where the factory line goes.

Am I correct in assuming that the R32 is different. From reading the regs outlined in your first post, it only seem illegal if the vapours vent to atmo?

[Cubes]

The R32 also plumbs in to the intake pipe just after the AFM but also to the Plenium chamber.

Maybe some sort the boost & suction equals out?!?!?

[Steve]

That sounds like a good theory to me, when under boost 'tis probably unlikely that the plenum will be providing any sort of crank case ventilation.

[Cubes]

If that is the case though why do we need a catch can?!?!

[Steve]

Well, you would still need to vent the crank case when running under boost, and to vent the vapours to atmo is illegal, at least the catch can will go along way to removing the excess oil in the vapour.

[Clint32]

the stock setup would suck the vapours when in vacume and suck them through the turbo when on boost. If it is legal just to have the lines in the air filter pipe its not much different than just having a filter on the catch can.

This is the problem when people start listening to greenies, things can turn to shit
