I'm not an expert but I know for a fact the OFH is a WAY BETTER OPTION. You get oil that has just been filtered and I think access to more oil.
I would try googling to see what restrictor and oil drain size.

Btw if there's still a silencer in there you should take it out.

E:Sidenote, is your car black or purple? Looks good, wish the picture wasn't so small.

Found on google,
"The holset is fine with stock 4g63 oil pressure from the oil filter housing. If you have no b shafts, you'll need a restrictor. The drain line is a garret bolt pattern. The feed line is different for different turbos."

He needs to search. Drain should be -12 port the oil relief valve and yes feed -4 from ofh. It's all there in the holset oiling thread... Read up

Oiling is the same for the 35 and 40, they use the same bearings and everything.

Youre going to want to search for the threads covering holsets. There is a lot of useful information including causes of failure, correct oil pressure, correct oil feed location and restrictor size, and also the correct drain size for oil drain. Youll find good arguements and pics on the setups that fellow tuners are using.

...for starters, a large majority of these guys recommend nothing smaller than a -12 size line and fittings for your custom oil drain. Next you may need to run the .078 restrictor feeding from the oil filter housing. Some guys feed from the head. Youll need to guage the amount of oil pressure that the turbo is "seeing."

I personally dont have any experience with the holset, but i did consider going with that setup. The info that I found is definitely worth the time

You'd almost think we keep this information a secret or something.

....but we don't.

I think I can add an additional gauge in my car to check the pressure of the turbo, but I have installed oil gauge in my OFH
Or you mean other extra oil gauge?

so now this inside my car...

Thank you very much to all that took time to answer and so I was reading about the Holset need-12an oil drain, oil feed line-4an and 080-085 oil restrictor, I know that in these post not Information must be classified, so I will put an ad in WTB

Not to get off topic but you may want to check whether or not that Holset is real or knock off, if it matters to you. The compressor nut looks wrong. But yes there are pages, like 10+ on how to setup a holset and which drain is best. Iirc the best drain I saw was a stock metal Holset drain that then had a stock mitsu drain (pan side) flange welded to it. It was metal and was plenty big enough since it was stock Holset drain. Good luck and post up when your finished. Most if not all feed from the oil filter housing for a Holset.

Archer Fabrications · Feb 28, 2014

^ the compressor nut is wrong? You do know thats fricking EASY to replace right? It could have been done during a rebuild.

You dont need a restrictor with a -12 line if your pressure is fine. I dont run one, just straight ofh -4 to turbo :thumb:

think anyone would like to have something and then realize it's not what you think

Didn't think of that. Good call.

Do you keep the balancing shafts?
if I install a -12AN oil drain
How can I know if the pressure is correct?

That turbo looks legit to me. You could always reference the serial number.

The turbo is real. I dont have balance shafts, if you actually read the thread i posted way earlier like i said, it has everything you need to know about installing one of these, checking your pressures, and where to buy the fittings. Look at it

Incorrect. It's very real.

Install an aftermarket sensor, the stock one isn't anything near a real accurate gauge. and if justmx says its real, I would take his word as fact when it comes to turbochargers.

talontsiawd08 · Mar 1, 2014

Thank you very much to all for your comments, I have resolved my doubts, someone could tell me where to buy these parts, especially some link please

Also interested in 90 degree fitting in OFH

Archer Fabrications · Mar 1, 2014

Yep since those are my pictures! I'll show you whats up.

I got a cheapo oil pressure fauve from napa, that fitting i got from summit racing bit found it on rtm as well. Let me dig up the link.

The 90* fitting is an extreme psi oil feed from the ofh for the turbo.

talontsiawd08 · Mar 1, 2014

Thank you very much and sorry for taking the photos, I will use-10an oil drain and the same restrictor you used
I will continue in the footsteps of your post

Archer Fabrications · Mar 1, 2014

Wait wait wait no no no no -10 you mean -12 right?
And i already told you i didn't use a restrictor. That fitting is just to plumb a temporary gauge in to see your pressure to determine if you even need a restrictor or not.

No need to apologize for the pix. They are there for everyone.

Dsmkauai · Mar 1, 2014

You need a bigger return than -10! Try -12 or bigger the oem drain is 3/4" big so its best to try and match that. I used part of the oem drain line and made my own with parts of that and some fittings!
