Best 'off The Shelf' Catch Can

[Blitz]

nick - ive spoken to darron @ justjap - they onloy have the type that sits at the back of the rocker cover

For R32's yes, the one I posted is the R33/R34 type.

greenline lists them on their site

[c0ris]

yep thats essential, i got mine from greenline

[Marko R1]

i am undecided which way to go...

1. 'border' catch can which vents out the top of the unit with a flat filter (from greenline or rhd)

OR

2. 'essential' catch can as pictured which dont vent out (from greenline or rhd)

what is better for engine? as i understand it venting out is illegal however it does its job better by keeping the air cleaner & not returning it back into the engine...thoughts?

Is it essential to have a catch can?

I have an after market intake pipe and just have a hose off there to the rocker cover breather (the one that usually plumbs into the plumb back pipe) as I have taken the plumb back pipe out

can u post a pic of your setup?

Yeah man, sure

The hose in the yellow goes to a metal intake pipe off the turbo, sorry don't have a recent picture

Thats fine abu. I run mine the same at the moment, though i do plan on reinstalling a can at some stage.

I ran without a catch can for 3 or so track days with no issues. I found the can was always dry afterwards so wasn't worth keeping when it got in the way of reinstalling the stock airbox

From what I understand catch can is used on turbo engines running higher boost levels for long periods,

like motorway or racetrack.

The factory system works by air starting at the intake pipe side (before turbo) and ending up inside the

intake plenum via the PCV (Positive Crankcase Ventilation) valve.

You have to block PCV valve hole off and block the intake pipe hole (before turbo) and run 2 hoses from each

camcover to the catch can. Then run a single vent line to under the back of engine. Or vent via a filter

on top of the catch can.

Size in litres, depends on engine capacity and racing regulations. I think 1 litre is minimum

for a RB20DET.

This is probably one of the best guides to building your own catch can, swirl pot that I have seen

with the vent on top of catch can -

Autosport Engineering are the people to contact in the above link.

From what I understand, what's good about the above catch tank, is it separates the oil from

the air.
