Well his set up isnt an "oil breather" the breather system has a breather on it and doesn't send those sh*t gas's back into the intake...

You could hook it up as shown with a catch can that has a breather on it and not run a line back into the intake.

Don't have pics of my old set up on this computer, but both lines off the head simply run to a catch can with a breather and the bits get blocked off so the oils in the catch can and gas's out the breather!

Yea mines like that aswell... one hose from the head to the catch tank and nothing comin out the other side except a little filter on it, dunno if thats how its meant to be the workshop i go to did it.. i didn't need to block off the intake pipe cos they made me a 3" S/S one...

Blocking off is obviously only if you have the bit there on a standard intake pipe :laugh:

Usually its better to run 2 lines to a catch can with a filter ontop of the catch can so both lines are free'd up rather than using one, i used one small one and it built up pressure in the system which meant bye bye turbo oil seal! Made 2 fat lines with a breather on the catch can and it didn't pressurize the system and kept all the sh*t outta the intake of the car, you'd be suprised when you empty the can how bad that oil actually is lol

I guess the blow-by on a old rb20 runnin 20psi was always goin to be greater than most though :laugh:

My catch tank is as clean as when i baught it... i'm running 6psi mind you lol

so exactly whats the correct way? wether its legal or not i just wana know cos some people do it differently i suppose or the way your saying jazza80 is that the right waY?

If its clean inside, its means you have f**k all blow-by which means your engine is in top nick, and im not suprised running that boost level, sounds very safe :laugh:

Legally, it isn't supposed to vent to the atmosphere, so running the lines to a catch can to catch any bad oils, then back into the intake (for the gas's) is the best way to do it.

Illegally, to keep all the sh*t out of your motor you use a breather and don't run it back into the intake...

Just make sure the system has a way to breather (wether that be via the intake or a breather) as without it it will pressurize and cause you some big big problems.

I have found that from having catch can problems in the past with my last car, lines to catch can were abit too small.. built some pressure up and blew the oil seal on the turbo, made both lines bigger with the breather ontop of the catch can and it never pressurized the system! Thought id try to help out so you didn't end up doing that lol

      ECU sees many times the speed than speedo does (R34 swap)

      By Kapr · Posted

      The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.

      Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

      The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week

      Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
