Hi all

I've finally got around to installing my hks gtrs turbo on my GTT and I'm unsure of which ports in it are oil feed and water feed and drain. Could anyone please confirm which ports these are?

Also if anyone could confirm which ports are oil and water feed on my engine block/bay that would also be greatly appreciated :)

Cheers

Hmm.

I'll be nice.

There are 2 water ports.

There is one drain.

There is one oil inlet.

The drain is larger than the inlet. You can even look at your old turbo as they are the same oil and water setup.

Good luck.

Sorry I'm fully aware that there's both a water feed and drain and oil feed and drain (I'm not that dumb). It's obvious which one the oil drain is but I'm not 100% sure which the other 3 are as there are no markings or diagrams I can find on the internet. Just asking on here for clarification as I don't want to destroy a hks turbo from getting the oil and water feeds mixed up. I posted that at 1:30 in the morning so sorry for not making myself clear

Looking at the turbo again on the top and bottom are 2 thicker lines

And on the sides are 1 smaller line and the oil drain

Safe to assume the smaller one is the oil feed and the thicker line at the top is water feed ?

It gonna sound harsh but if you cant figure that out you should think twice about your ability to fit it properly... anyone can bolt things together but if you dont understand why it often runs into issues later on.

Sorry I posted this asking for confirmation as I thought someone would know. Would like to be 100 % sure about something before I do it to my car, not. 99%. I've figured out the oil feed and just want to makes sure I don't mix up the water ones

Also I'm referring to the positioning of the inlets in respect to the pictures that I uploaded. When I say top I'm referring to the inlet at the top of the photo etc. thought what I was saying was pretty straight forward ..

Was just trying to sort out which is the inlet and outlet for water as I thought it had to go in a specific way but it's all sorted now. Found out it's dependent on the angle of the turbo and nothing to do with the internals or anything

It's not really even dependent on the angle of the turbo. Given that the oil definitely has a top and a bottom (ie, drain on the bottom) that means that the water definitely is located on each side. Sure, if the turbo is cocked over on an angle then one water connection will be higher than the other.....but there's little enough difference in that height to justify saying that one or the other must be the inlet. A hot turbo will thermosiphon forwards or backwards just as happily once the engine is shut off, and it hardly matters if the water is going the normal direction or the opposite direction under those circumstances.

      Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.

      List all of your mods. It sounds like an aftermarket ECU hitting rev limiter. Like a valet mode, or a cold rpm limiter?

      "Cheap" bolt on turbo on RB25DET NEO

      By tylink720 · Posted

      @Kapr Haha yeah thats the one. I missed that you had a built up engine, I wouldn't want to run it on there either then. It was good in my situation just to replace the original turbo on a stock engine. @MBS206Yep definitely not a replacement for anything name brand
