Hey everyone

Just wanted to know if anyone has been defected for a oil catch can in NSW? Im new with this and i have a couple of questions, i hope someone can help me out.

I have a r33 series 2 and just wanted to know whats the difference between:

(a) rectangular oil catch can to a round one?

(b) is it better to have a breather and what does it actually do? I cant seem to search for it on the net. Heaps of link comes up but doesnt really explain what it does.

Thanks for your help

a) one is in the shape of a rectangle, and the other is round.

b) breather is for setups that have the air venting into the atmosphere (atmo). its really a personal preference on if you want to recirculate the breather air or make it atmo.

technically it isn't/shouldn't be a defect if you recirculate the air back into your intake - but cops in NSW are arseholes. once i got defected for 'engine modifications'... like wtf??

if you get a cop who doesn't know what he is doing he will defect you for it because it isn't standard, and that is the case with 99.9% of NSW highway patrol - so for safety's sake i'm going to say yes, its a defect because REALLY its you and your luck.

Hi there,

Well my question really means is there a difference between the round and rectangular catch can. Like do they work differently or one of the type is actually better than the other.

Yeah some cops are asshole and some are dumb!! I got pulled over once when i had my stock integra, the cop asked me if it was modified and he checked under the bonnet but im not scared because it is stock as a rock then he asked me if it was turbo? Im like WTF hahha

    • Power steering is probably because someone has nuked the HICAS CU and you no longer have the variable power asist doing what it is supposed to. How much boost are you running? You are aware that any more than 10 psi on the stock ECU is just asking for it to go to full R&R (that's Rich & Retard, which is effectively Retarded and Retarded!) which kills all the power. Depending on the exact conditions, it can just be runnign on the fat and stupid end of the maps, then the conditions change, you make a little more boost and the ECU goes into panic.
    • @BuiltNotBought Just as GTSboy said.   If you want driveabilty and more low down torque..keep the stock runners. They are VERY good from a factory. I have them too on my RB25DET NEO and as a GTSboy i have fmic but with stock piping route(i have Blitz intercooler) Iam making around 320 BHP and the car pulls "hard" from like 2,5k all the way to 7k. I have it dyno tuned to mimic N/A power curve and making little less max torque due to the smallbox tranny. But driveability is very great. I had 350Nm below 3k so car feels very quick.   EDIT:  Not my channel but i saw this and i know that is what i want (and i have exactly this)  
    • Looking to sort out a couple of issues on my skyline  It recently was rebuilt, however rebuilder long story short did not give two flying effs about the work he did. So moving forward it's running but I have two persistent issues 1) it has a misfire / lag type of issue (was at higher RPMs but I had a dead piggy back ecu removed which improved it) now it's not as bad but still does it at random, I thought it may have been a boost issue I'm running an older turbosmart dual stage controller, turbosmart told me to try running off gate pressure however it still has a lag at random times. It has New MAF, maf plug, coil packs, sparks, CP harness.. injectors tested and cleaned. Factory ECU. 2) Power steering issue. It is tight as anything. Flushed power steering, rebuilt my pump because the bearing was shot. Flushed again still tight (mainly when parking and going slow into my driveway etc)  No kinks in hard lines, replaced the lines I could see had cracks. Still tough to steer.  I was told to shim a coin and place into the solenoid plug? Is there anything else. My steering angle sensor also has a issue. It's a used one I replaced, does it need to be calibrated? I feel like I've tried everything and this car is my voodoo doll.   
    • Holy shit... wow!!! I totally missed this
    • One main filter. Each tank has a prefilter to keep rocks and small children out, then the big main filter that also does water separation. Clogged the first one so bad it was like a rev limiter at 3200rpm. Literally just like dropping the throttle off and maintaining rpm!
