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

looks good

do you have any pictures of it installed?

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 is exactly right mark :blink:

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

    • I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.
    • @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation. 
    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
