Do these turbo lines look OK?

[neil_se]

We put on my "bolt-on" hks2530 turbo and, well, the stock lines don't match up. Because we would have needed a fitting for the closest water line and a T-piece for the one around the back we just cut the metal lines and attached some 5/16" fuel hose which fitted nice and tight. The braided oil line was just looped back around to the block as well.

We think these should be alright but thought it might be wise to double check with people in the know so i don't stuff up my new turbo

I think you might find the fuel hoses will not cope with the heat that will come from the turbo.

It should be ok for a sort run up to auto one to get better (heat resistant) hoses.

Just my 2c worth of advice

Yeah, what Stagea man said I had to do something very similar when fitting my new turbo, and the heat of the turbo (and don't forget that two of those lines carry engine oil...) meant that I went for lines meant for an oil cooler. It's reinforced and is designed for exactly what it'll be used for!

Thats a fair bit below the turbo there though.. and its about the same distance to other essential (plastic covered) wiring to the O2 sensor and things.. and also the rubber heater water lines run past the back of the engine, at a similar distance with no dramas. So I think it would be ok, but I'd be keeping a close eye on it.

I would still most definitely be erring on the side of caution - a burst line spraying oil onto the turbo and exhaust manifolding can't be good

My main concern would be using fuel line - yes, fuel line sits in some pretty warm spots too, but fuel tends to be far cooler than engine oil, so the design tolerances may not have accounted for high temperatures *inside* the line. I may be completely wrong and fuel line could well be perfectly safe in this application, but unless you're 100% certain, IMHO it's not worth the risk for a combined total of maybe $30 worth of replacement hose.

Just read back over that and tiredness + a few drinks mean that it might come across as aggressive. It's not meant to be, just trying to reinforce the importance of making sure the oil/water supply systems are not skimped on Don't want you guys thinking I'm being nasty, lol

If you go t pirtek or enzed, you can probably buy some nice heat resistant line. Peace of mind would only cost you a couple of dollars:)

Thanks for the help guys. The rubber hoses will carry water, not oil (that's what the braided hose and bottom return line are). I wasn't worried about the heat of the liquid travelling through the hose because at the other end of the closest hose in the top picture there is a rubber hose from factory. I was just worried about heat from the manifold and turbo, but as someone said, there are other rubber and plastic hoses that travel just as close.

edit: oh and that very bottom hose is the same as the stock return pipe so i assumed the rubber section in that would be alright.

try and get a better oil return. Mine is still rubber like that, but i was told that the 1 item you shouldnt skimp on is the oil return

nice braided oil feed !

Get some high temp hose from pirtek just to be sure.

****.

I thought my 2530 was gfoing to bolt up as well, I used a standard RB20 oil return but the flange had to be redrilled to fit. I guess I am going to be pissed off when the stock liines dont bolt up for water. I have a braided oil feed as well.

thanks for the replies. i'll definately get some high temp hose from somewhere tomorrow although it'll be a bit trickier to put on now the engine is in the car. ah well, better safe than sorry.
