anthonymcgrath Posted August 30, 2010 Author Share Posted August 30, 2010 @rad32 I dont have any heat proofing on my lines but they're braided? are they really going to suffer that much? My oil feed also runs down between two manifold runners also. Your manifold is certainly a tight fit in there - heres the space around mine...

anthonymcgrath Posted August 30, 2010 Author Share Posted August 30, 2010 yeah v.weird but the manifold I have was a T4 one that I had a T3 flange welded onto but its strange that there's so much room. that said its a 33gtst shell. is it worth me fitting these fire hoses around the lines then? Is there an alternative like some high temp silicon hose maybe? my wife is dancing to spanish music around me as I type this hehehehe!

rad100 Posted August 30, 2010 Share Posted August 30, 2010 i just went to outlaws and bout 3feet, that was $60.00 i herd its good, i guess anything to extend the life! oh and i have to space my manifold 10mm out as the turbo would foul on the rocca covers!

anthonymcgrath Posted August 30, 2010 Author Share Posted August 30, 2010 ah I imagine my own turbo might have done the same then if it wasn't for the T4/T3 adaptor plate welded on heres a coupla pics for you as you requested thru pm mate: from the front... reckon it would have fouled on rocker covers too... cylinder head had to come off thanks to the stubborn manifold studs.. turned out 2 valves needed sorting and it needed a slight skim n refresh... this is my wifes fmic piping! She's rather pleased about it as you can see lol! my water feed line passing underneath... the adaptor/restrictor in my turbo - not sure if I need a washer in there to space it out altho I was told it mates up to the oem restrictor in the turbo...

anthonymcgrath Posted September 1, 2010 Author Share Posted September 1, 2010 hey guys wondering if anyone can help me here with the oil return a friend of mine sent me this link to ATP turbo - I'm tempted to order it for my gt3076... piccy below... Oil Return Flange with integrated -10 Flare for GT15 Through GT35R If I ran with that, can anyone tell me what thickness I'd need my oil return pipe? I dont want to order it too thin. I THINK its a 3/4" pipe like a heater hose but I dont know if thats right or not? on the end of it I would need a -10 AN female screw fitting to screw onto that oil return flange. However.. on the other side I'm not so sure. I've been told I can unscrew the fitting on my block below... ...and then fit another fitting but I dont know what size it would be really. I'm also concerned because the pitch for the oil feed adaptor into my block was slightly different from the one on the turbo. so I think to sum up I need to know: 1 what thickness of oil return line to go for? 2 what fitting I need in the block for the oil return. any advice for this would be brilliant guys - you've all been massively helpful as it is and theres a fonte of knowledge on this site with you guys mostly having done this conversion far more than the uk has heh! ta ant Link to comment https://www.sau.com.au/forums/topic/328679-oil-and-water-supplyfeed-for-top-mount-gt3076r-turbo/page/2/#findComment-5426238 Share on other sites More sharing options...

My oil feed also runs down between two manifold runners also.Your manifold is certainly a tight fit in there - heres the space around mine... i'd be a bit concerned about how close your braided lines are to the exhaust side of the turbo, just cooked my braided line which was close like yours, got a hard pipe section made up, cost about $40AUD, was told exhaust side of turbo gets up past 700 degrees and braided lines are rated to about 350 degrees...and make sure your water feed and return are on different sides of the pump so there is a good flow.. you can't go too big on the oil return, I think mine could even be 1". good luck Link to comment https://www.sau.com.au/forums/topic/328679-oil-and-water-supplyfeed-for-top-mount-gt3076r-turbo/page/2/#findComment-5426273 Share on other sites More sharing options...
anthonymcgrath Posted September 1, 2010 Author Share Posted September 1, 2010 yeah I need to adjust how they're seated - that pic is a bit old now. It'll be free of the exhaust side of the turbo soon enough and if I can protect them then I'll do my best. I'm looking at purchasing a turbo jacket anyways. its not so much the oil return pipe I'm worried about as the fittings - I've read all kinds of bits about how the thread in the block is tapered or something. I'm just a little in the dark about it all. Basically I would need: -ATP oil return flange for the turbo -10 AN -gasket for flange -piping (braided or metal) - 1" or 3/4" -10 AN female fitting on the end of the pipe that sorts the side that bolts to the turbo I think... ...but then I'm in the dark about what comes off the block? What thread pitch and what size bolt will that oil return fitting on my engine be? If I know this I can get the adaptor that will fit in my block and have the other side of the oil return line fitted with the correct female end?

anthonymcgrath Posted September 1, 2010 Author Share Posted September 1, 2010 I'm just looking at this wiki and i would hazard I guess I actually need -12 AN ?!! http://en.wikipedia.org/wiki/AN_thread I'm totally lost with this now - the myriad of information like AN, NPT, JIC etc is just labrynthine this chap posted up a bit of info on here, but thats losing me too...

anthonymcgrath Posted September 1, 2010 Author Share Posted September 1, 2010 okay this is what I have so far... oil return flange for turbo + gasket oil return flange from ATP for the block I unscrew my current oil return push on fitting (pic attached) and install this.... adaptor for block my understanding is that I screw the side that is 3/4 NPT into the block? Then I just get a braided -10 AN hose made up with a -10 AN female end on both sides. Is that right? sorry for all the questions but if anyone can offer a thought to this that would be great. I'm no good at bojjing bits with a welder and I really dont want to do it on what is arguably one of the most important bits of the car!

rad100 Posted September 2, 2010 Share Posted September 2, 2010 i would also like to know the above.. ill take pics of how my lines are sitting but i have a feeling they run abit too close to the rear housing.. are hard lines expensive? dont really wanna do it as i just bought all new speedflow fittings!

anthonymcgrath Posted September 2, 2010 Author Share Posted September 2, 2010 I was told by Richard @ RSP over here in the UK that I ideally need a metal pipe running off the turbo.. at least to get past the manifold and the heat. Then the latter 1/3 of it can be silicon hose on the push on fitting (stock fitting) on the block. My plan is... buy this for the block... remove oem push on fitting and install... earls -10 AN to 3/4 BSP adaptor buy this for turbo... -10 AN oil return flange for GT series turbo then contact earls here in the UK and have them make me a 60cm oil return hose with straight -10 AN fittings on either end. I'll buy some fire sleeve for the oil return too to help keep the heat from the manifold off it. I think this will be the neatest option personally.

rad100 Posted September 2, 2010 Share Posted September 2, 2010 i think im gonna get my exhaust shop to wed some tube onto my drain and bend it down to the block and attach it with an inch of hose.. then heatwrap/sleeve the tube.. coz the drain is gonna be Fecking close to the manifold.. also bought a turbo beanie to help my lines seeing as there real close!

anthonymcgrath Posted September 2, 2010 Author Share Posted September 2, 2010 yeah I might yet consider having Earls make up a metal pipe for me with the straight -10 AN fitting on one side just so I can get it past the manifold. I might phone them to see if they can come out ot me and make it up for me in situ. But first I need the oil return flange and the adaptor for the other side. oil return flange.. bloody thing is $60 dollars shipped to UK.. why aren't these things included with the turbo? Its clear you cant fit anything to the turbo oil return location unless you run the oem one off it hey ho..

aleks Posted September 3, 2010 Share Posted September 3, 2010 My oil return tube is about 100mm and i had to cut and weld it to a 15-20 degree angle because it was fowling the manifold. the oil returm hose touches the manifold.

anthonymcgrath Posted September 3, 2010 Author Share Posted September 3, 2010 I'm contemplating just phoning a metal worker and asking them to come out and make me one up instead so I have a hardpipe instead. I've had enough trying to faff on with fittings especially purchase the sodding things here in the UK. the oil return flange for the turbo is $28 then a gasket $3 shipping.... $28 ?!!?!!??!!?!!!!!!!! for f**k sake man. honestly I'm fed to the back teeth of this - I've sat staring at this car now wondering what to do with this sodding oil return line for the last 2 weeks. Everytime I come up with a method I just hear someone come up with a reason as to why I shouldn't go that route... its like NO method exists at all. thoroughly fed up with all this now I really am Link to comment https://www.sau.com.au/forums/topic/328679-oil-and-water-supplyfeed-for-top-mount-gt3076r-turbo/page/2/#findComment-5429767 Share on other sites More sharing options...
