Rb26 Oil Catch Can

[R32 Zilla]

Firstly i have : R32GTR with built motor, R34N1's running up to 21psi.

Iam getting a fair bit of oil in my intake and intercooler pipes and i want to fix this asap. The problem is that I have VERY limited space in my R32 engine bay to fit a catch can.

As I see it I have 3 options:

1 - Relocate the battery to the boot and fit a decent size catch can in its place. This means a bit of stuffing around with wiring and the loss of some boot space. Would have to buy battery box. Is it legal ??

2 - Buy a small $300 odyssey battery which would leave room for a catch can in front of it.

3 - buy one of those catch cans thats sits accross cam covers at the back. See pic below. Would these do the job and do it well? It would be the cheapest and easiest option.

How big does it need to be? Most seem to be about 800ml to 1 litre. Is that big enough for an RB26 that does the occasional hill climb and drag event?

What catch can setup does everyone have in their GTR?

Any suggestions would be great.

Thanks

Tim.

hhey mate i just got a 800ml one from autobarn lol but i think it will do the job...how is the gtyr going mine is slowly coming along...

[R32 Zilla]

Hi Kane, yeah it is going well. We will have to meet up and go for a cruise when yours is on the road. i have been following your build thread.

where are you going to mount the catch can?

[gun32gtr]

yeh its coming slowly just trying to get my mate motivated to come round is the trouble lol...cruise for sure that be great indeed...i have not been in a gtr for over 18months now and i need a fix lol so the sooner the better...

regarding the catch placement i think ill just put mine infront of battery as it fits nice indeed...your welcome to come round and have a look anytime mate...

Do you have the oil control modifications done to the motor? The catch can may be a bit of a band aid fix for oil in the intake, but a much cheaper fix.

[R32 Zilla]

I have no oil control modifications done apart from a baffled sump.

Cusco sell a 3L catch can that fits behind the battary. I've got one, it's great.

here's a pic stolen from Beer Baron's RB26 for sale thread of what the can looks like

sav man .... The battery I have now is too big but if I bought a smaller battery that is exactly what Iam looking for.

How have you got yours set up ? What inlet/outlets does it come with ?

Where from and how much ?? I can only find the smaller ones on the net.

Thanks

I found the on top of motor catch can (powerplay, jjr etc) fouled up the engine oil very quickly, so unless your doing track work and running the sump dry due to blow by i'd steer clear of it.

anyone know the hose internal diameter for the catch can hose on the rb26 covers?

My is setup identicle to the pic. It comes with that clear hose, and a bung to block the breather line going into the turbo inlet. You will need to buy a filter (like $5) to put on the catch can outlet though (the bit on the drivers side of the battary).

www.greenline.jp have them for $179 + postage, Cusco 3000ml car spesific kit. Part # is "231 011 A"

i think the battery to boot is a good option.

but as you said alot of work to get it there.

i've been in this process for some time, also building an airbox to suit the trust cross over/hard pipe kit. and a catch can like the arc number with radiator overflow and washer bottle in one..

similar to the 33/34 gtr model but to suit 32gtr

if you plan on doing cams events like hill climbs etc check the cams regs regarding catch cans. They need to be specific size etc by engine capacity and whether there externally vented or return to the sump.

Of the top of my head i cant remember the specs.

[Beer Baron]

from memory cams regs state it has to be bigger than the capacity of the engine. hence the GTR racing one being 3litre. the one I have is fitted there with the standard sized battery in place. if yours wont fit there then for some reason you have swapped to a bigger than standard battery (bad idea). it's 3l so in a standard size RB26 if things go wrong it can hold pretty much a whole sump full of oil.

[R32 Zilla]

Yes I realize now that I have a bigger battery then standard and I will change it to fit a catch can.

I emailed Greenline about the 3L Cusco one and they said they have none in stock but could get one made.

That ARC one for an R32 posted buy Angus Smart looks ok. Thats the style Iam after. Anyone got any info on it or a link i can go to? Cant find it for sale anywhere or any info on it.

I dont no if this helps but here's a picture of my catch can.

Ignore the writeing.

[R32 Zilla]

Yep Rav that would be good. Where did you get it? or was it alredy fitted when you bought the car.

[Shaun]

Heres a catch can that i made up for my R32. It has baffles inside it too. Obviously the battery is in the boot. I also made up a box for that.

Sorry about the size of the pic.
