Hks Gt-Rs Oil Line Specs

[bzkr33]

Hey guys,

Hoping someone can help me out or point me in the right direction.

I've recently picked up a GT-RS turbo for an rb25det, however it hasn't come with any lines or oil drain.

My question is can anyone tell me what size oil drain is required, or steer me in the direction of where to pick one up? I have done some searching and haven't been able to find any information on this.

Secondly, the oil feed, again I have searched but I still can't find a clear answer - some people say this turbo requires an oil restrictor and others say it is already built in.

Can anyone with this particular kit tell me the specifications of the original oil feed (and oil drain as well) so I can match these? Or if someone that has installed this kit and used an oil feed other than that which is included in the kit what they have used?

Cheers and thanks in advance!

Thanks Wolverine, I've sent him a message!

Would anyone else happen to know any info about the lines?

On my rb26/30 build I sourced my braided lines from kando dynamics, ebay seller. Great lines, great price, turned up quick and worked well. He had every conceivable combo for rb26's so probably carries stock for popular rb25 conversions.

Dunno about the gtr-s but my 2835 has the restrictors built in, I guess they would be the same.

I reused the speedlow fitting that hypergear gave me with my highflow for the oil feed so I didn't have to use the dodgy looking right angle joiner that attatches to the banjo.

Thanks for the reply guys, I don't think the drain will be too much of a problem now, I've gotten some very help info from discopotato03 to clear this up - thanks mate much appreciated.

The only thing I'm concerned about is the oil feed, too much oil and you'll blow oil through the seals and too little will starve the turbo and seize it.

To confirm if there is a restrictor built in the oil feed port, it should look like this yeh?

Yes that inverted flare should have the correct sized hole through it .

Its actually a mushroom shaped device that fits into the oil hole in the actual bearing cartridge ande locates it in the turbos center housing .

Thanks again mate, from what i have picked up along the way in the inverted flair there is a .5mm hole which does the restriction?

With this and the oil drain sorted, all I have to do is the water lines which shouldn't be a drama.
