Most catch cans only have 1 inlet 1 outlet, so for the ones where u need to attach 3+ hoses to it, do u just use a T piece etc?

The ones we use have 4 fittings, 2 inlet, 1 drain (outlet) and 1 filter. There is no reason why you couldn't use a T piece although a Y piece would be better for plumbing. :)

Even with the pictures im still clouded as to which way i should use mine  

I found this photo, what does this setup offer?

This looks llike the 100% plumb back alternative. It is a little hard to see the PCV pipework, but I suspect that both the inlet and oulet for PCV is plumbed to the can. Certainly the inlet to the turbo is plumbed back, so it would makes sense if the PCV was similarly plumbed back.

Why are you still clouded? :(

For what it's worth here's my setup....figure out which one it is . Remember most bought catchcans have 1 inlet and 1 outlet the inlet should feed to the bottom of the can

As long as you block off the unused plumbing and fittings.  I gotta ask why though? :confused:

Well, we're recomending to block the PCV line on a vent to atmosphere setup, so if you block the plenum side of the PCV line, and use the PCV port on the side of the rocker cover, you get a very tidy catchcan setup with only one hose :(

This is the style of catch can we use. http://www.gcg.com.au/catalogue/Oil%20Filt...tor%20round.jpg

It has the 4 fittings;

*2 inlets on the side at the top (we run a piece of pipe to the bottom and then cover them with stainless steel wool, inserted via the large air filter fitting.)

*1 drain (outlet) at the bottom (we put a tap on this, so we can open it and drain it)

*1 filter on the top

This setup is the same as mine, it still vents to the plenum via the PCV valve when neg pressure is present in the plenum and vents via the catchcan to the turbo intake pipe when pos pressure is in the plenum....only diff is my catchcan is on the oposite side to shorten the tubing and looks tidier. There is no venting to atmosphere....it's on my street car....and legal :D

Yeh sweet that sounds perfect

Only thing is i want to block the PCV valve, seems to have all benefits and no disadvantages from doing so

So whats the best way to block the two holes/hoses? Im assuming just cut the hose going from the plenum to the rocker cover, and screw a bolt into the hose holes

i went to power diggers workshop in ingleburn today and the owner told me that the boost pressure source could be teed from the vaccum hose that runs from the throttle body to the air con canister.I didnt question it because ive had one on the car in that exact same location ever since i bought it, it had just been capped which means it can be located even closer again.:cheers::(:mad::mad:

A question about my proposed setup for an oil catch can.

1.In this picture you can see the pipe that goes from the plenum to the rocker cover.Now if i put a aftermarket pcv valve in the middle of this hose so pressure only travels to the rocker cover and not backwards to the plenum is this allright to do?

The catch can is rigged up the same as the one in the picture.

What i was thinking was that by putting the valve in there it would only flow air when on boost and when off would eliminate oil travel to the plenum when off boost.And the catch can setup should pretty much take care of the rest of the oil blowby on its way to the intake pipe.

tell me if i am wrong please.

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
