Hey guys,

I've spent the last 20 minutes or so looking for info as I was sure plenty of people had done this, but I couldn't find anything. If this has been answered, please just point me in the right direction :)

So basically while I have the head off, I want to make up some braided water lines to replace the stock hard lines. Reason being is that with the ATR43 G3, the stock lines are reallyyyyy very difficult to get into the turbo. The one short line is easy enough, looks like I just need the banjo fittings and I'm good to go.

But I'm not sure what to do with the second line, the one that goes behind the head? I can see that this is a push on fitting on the other end. What do most people do when going to braided lines here, do I need to get an AN fitting welded on somewhere?

Thanks for any help,

Cheers,

Martin.

You can actually buy kits, and for the one that replaces the hardline at the back of the head, that end has a push on fitting from what i can see/found when i looked.

I spose it just depends how far you want to go.

I have been looking at the same water line on my Neo and have been wondering the same thing!

As said and pictured it's just the push on fitting, but make sure when installing that there isn't to much/any up and down in the line, or you could have issues with airlock in the lines..

Remember it needs to thermosiphon ( spelling?)

Yeh, I will try to make it follow the same path as the stock hard lines. May need to make brackets??

So with the push on fitting, can I just use the stock one and get braided hose to suit? What about size of the line, I take it I don't want to go any bigger than factory or I may need restrictors? I'm not really keen on buying cheap kits off eBay, not when it's so easy to make them myself. Speedflow gear isn't too expensive when I'm putting it together, so I'd rather do that.

my turbo has the braided line, it is connected to the original line just at the back of the head, fittings are all silver and look like there meant to be there, seems to be good enough :yes: i think its best not to go overboard incase you are pulled over and asked to open the bonnet for inspections.. :whistling:

Eh, Western Aus, braided lines aren't cause for panic here. They would be the least of my worries if they were :P

How does it work using the braided hose as push on hose though? I would need to get a much bigger ID hose, does that not cause issues with flow?

yeah I just pushed braided line on to where the factory hose came off and hose clamped it there, think it is -6.. brackets or cable ties :unsure: maybe..I don't have either, and no mayor up/downs.

no restrictors required, its only water pressure.

Too easy then! Thanks Richard :)

mines the same as the image above, its the bottem hose of the three, so it screws into the stock line.. which is comming out at the corner of the exhaust manifold so that makes it a piece of piss to fit.. :yes:

interesting, the fuel hoses are -6 too..

Isn't that the oil feed line ??

Don't suppose it matters, and that sound does easy, leaving factory lines clipped and supported round the back of the head.

Right, I've flicked through the Speedflow catalog, and I think I've worked out a better way of doing the push on fitting end of the braided line. What I'm thinking is running with 200 series braided hose and fittings from the turbo to around the back of the head where the stock hard line goes into the push on hose. From here, get a male-to-male coupling like this:

20236Male%20coupling.jpg

And then get a 100 series push on hose end on the other side. Considering the coupling is about $3 and the push on fitting is about $7, this would work out much cheaper than the extra braided line I would have to buy to run it all the way to the bottom of the intake manifold where the stock feed comes from.

This is where I get a bit confused though. If I were to go with this method, what size push on fitting would I need? -6 still, or -4? The car isn't here with me to check quickly, so I'm not sure, but I'm leaning towards -4?

in that pic it does look like an oil supply line, confused me now, but anyway the bottem one is what mine is, i was guessing the other two are the return line and the feed from the back of the head, so 3 coolant hoses..

so only really need to do the 2 though, the one round the back of the head looks a bitch to get at.

bit of a thread dig but oh well, is appropriate.

so im installing an ATR43SS2 into my 33 and I have an issue with the stock feed line(the one that goes to the back of the engine) touching a bolt and the exhaust housing and also not being able to fit the water return line....

I am about the take the turbo out and rotate the core a little to see if it works seeing as though heaps have fitted them no problem.

but im also thinking of going to braided line cause itll be heaps easier in the future...

my question

the return line should be easy enough as i can access turbo side and the side on the block no problem.

for the feed which is a hard line that goes to the back of the engine and i cant see a connection point is it ok to cut the hard line with a hacksaw or something and fit a socket compression sleeve and fitting as in this vid i found?

The line that goes around the back of the head us1 actually the return line.

You can cut it off you don't ever plan on using it again. And do the conversion like in your video. It's pretty difficult, if not impossible to remove it with the engine in the car.

Easiest way is to disconnect it at each end, and run your new braided line to the intake manifold. You will need a barb type fitting and a small section of rubber hose to connect it to the manifold. Unless you can remove the fitting and press in a new dash fitting.

hmmm seems like itll be out of my reach in my garage, i am now gonna do it slightly differently as a temp solution, as the guy at enzed wasnt sure if the compression fitting would seal against the steel line...

im now gonna cut the line, flare the pipe, put a small section of rubber hose on and the small section of braided line will have a barb to go into that... hopefully it gets me going

      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.
