Hi all

Just wondering what people have done about installing a catch-can in an r32 GTR with an rb30dett. I had an autech-style one (big tubular one) sitting above the cam covers but with the rb30 in there, there is no chance of getting the bonnet shut.

I am on a low-boost run-in tune at the moment so hooked up the factory style setup but would need to sort something out before final tune.

Any recommendations about what you've used/bought/made yourself, and in particular photos, greatly appreciated.

Cheers

Andrew

Grab yourself a set of Mines cam cover baffles. These will greatly reduce the amount of oil vapour coming out. Then you can keep the standard setup.

I have these, they did nothing....sorry to say. I run the Pro Vent catch can with the return into the dipstick tube. Its a real catch can not just a shiny empty can.

Pro Vent 200

They are cheapest off ebay

You must have a fair bit of blow by then.

Myself and a friend of mine put a set of Mines baffles in both of our engines (both making over 400rwkw) and vitually stopped any oil vapor getting to the catch can.

i run a border catch can which i got from rhd japan then modified as directed by rob @ rips.

the correct way to run a catch can is to have both cam covers run individual lines to the top of a catch can which should have a filter, then run 2 seperate lines from the catch can (1 at bottom & another at mid point) back to the side of the sump so that it runs back into the sump

Pictures tell a thousand words ;)

The two lines back to the sump.. intake side? above oil level or below? seperate fittings on sump?

Thats what I though, leak down is less than 2% however. I think my issue was more an excess of oil in the head and-or to much Vac return. I am running the 1st breather from the high side of the drivers cam cover now instead of the low side on the passenger cam cover. Same as the Mines R34- dual catch cans (in series) Still returning to the intake. The PCV return has been blocked off. Will post up a pic later if you like.

Closed loop system to keep it 'more legal'

sorry bubba - 2 lines run from the side of the catch can back to 2 fittings in the side of the sump, at the highest pt of the sump

Hey Marko how's things?

2 lines back to the sump? that's a lot of drainback. almost sounds like its one line from the sump to let it breath (the one that goes in mid point) and the other is a return line.

That's how I understood it too..

My head already has the vent on the back so I will be going 3 hoses to the top of the can (2 cam covers and the vent from the back of the head) then I'll do it how Markos is, vent sump to midway up the can and drain from the bottom.

that would work

That looks just like the NISMO oil air kit which plumbs into the rear turbo oil line and looks pretty neat aswel I might add

The nismo Doesn't work on an RB30 block...with the turbo bolt-on return anyway. Def the go on a 26

    • It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪
    • And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil
    • Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.

    • Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
