Do these turbo lines look OK?

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 :D

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 :D 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 :D

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 :D Don't want you guys thinking I'm being nasty, lol

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.

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

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
