Rb20 Catch Can

[osiris23]

Hey.

Just a quick question about installing the catch can on my RB20det.

I have a aftermarket turbo and top mount manifold and the usual line which people plumb into is no longer.

Heres a quick picture of what i propose to do.

Is it correct? Is it the right breather to go off. Reason i went this one is it has had nothing on it at all since the new intake and everything had been on.

What do yous think?

where i have it plumbed into the inlet if it is correct i an going to make a little flange piece to come out of the silicone pipe.

Your intake plenum looks like a low cost option for those of us that want front mounts without the mass of intercooler plumbing.. what sort of money would a setup like that cost?? Isn't the fuel feeder/return for the injector rail mounted on the end of it? how did you get around that?

y not like this??

would be much easier

edit: does your can have some sort of filter?

I thought ud learnt John... god don't do that hahaha

If the system has no breather as that catch can doesnt make sure its plumbed back into the intake or has a breather somewhere in the system!!

You can run it like you have in your diagram no worries, This is how mine has been run for 3 years and it works well.

Just need to make sure the catch can is sealed, as if it has a vented filter, you will get a massive vacum leak at idle.

Also you will need some sort of filtration in the catch can, steel wool in a stocking works well, otherwise it will not work

Alternatively you could just block of the PCV valve and run two hoses of the cam covers to a vented catch can, but I found this to be a bit smelly for everyday driving

Yer ive heard about putting steel wool into the catch can. it might be a bit hard with mine as the only real opening would be the drain hole down the bottom. Ill see how much i can shove into it though.

If you can't contain it, with a stocking or something like that, I wouldn't bother, as it will end up in your turbo
