Resolved FF OFH turbo feed port ??

[phaseo]

Hi guys
I've tried searching through all the old posts but couldn't find a similar filter housing to mine, I assume it's from a jdm sohc turbo motor.
Any idea which port to feed my hx35 turbo from? Was planning on using the one left of the oil filter which is 1/4 bspt, the other option is the one right of the filter directly after the cooler feed which i think is 3/8 bspt.

Thanks a lot !

This FF OFH w/ oil cooler ports is rare, kind of unicorn. (I was looking for one for many years and finally got one recently) That's why you haven't found much info.
It's from older engines like turbo G62B/G63B. It technically fits with 6 bolt but the inside oil passage route is a little bit different from 90 DSM or JDM GVR4/Early EVOs. The oil cooler and the bypass valve is located pre oil filter. Not post oil filter like 4g6.

That's the factory turbo oil feed port and is located post oil filter. It is supposed to have an adapter in there from factory like the pic below. The port where you have the pressure sender is also post oil filter.

the other option is the one right of the filter directly after the cooler feed which i think is 3/8 bspt.

That 3/8 plug in the 2nd pic is pre oil filter. There should be one more 3/8 plug behind where you have the oil pressure sender. That's pre oil filter too. So the 3/8 plug location should have higher oil pressure but not filtered.

Thanks a lot for the reply, great information & I'm glad I got it right with the oil feed.
My tuner seemed a bit stumbled as to why people bother feeding from the OFH & not just stick with the stock port on the head which I didn't really agree with but hey he's the expert.

It’s a good thing there’s all this info and knowledge here. The stock locations are for stock frame turbos. You need better supply for the aftermarket.
