What do I do with the stock water lines that go to the oil cooler?

[Eclipse 1998]

Okay so I'm trying to install a B&M oil cooler but I'm not sure on what to do with the stock water lines, I don't want to loop them but would rather delete them completely. How would I do this? Also would I still need the water lines going to the turbo as well or could I delete them too? I plan on just having the Oil filter to OFH and do away with the stock oil cooler, I know I will have to cut the Oil filter stud as well.

usually 2g guys use the evo 3 style oil filter housing :see image in link below

But to save some money you can also just trim the excess off the oil filter housing... which is what you already had planed to do.

as for the water lines, you have three options.
option 1:could get a 1994-1997 mitsubishi Galant/Eagle summit/mitsubishi expo mini van 4 cylinder 2.4 4G64 front water pipe, that has no provisions for the oil cooler.
option 2: take the front water pipe off your car, and have all the unnecessary hose barbs trimmed off, and then have the holes welded shut at a shop that can weld aluminum.
option 3: well you already said you don't want to do option three... which is loop the lines with heater hose .
hope this helps.

Yea I already have the EVO OFH, well in that case if I did loop the lines from the stock oil cooler together and cap off the oil cooler nipples, I still need to keep the turbo water lines connected right ?

Yes, oil provides you some lube, water provides some cooling effects.

But wouldn't I be feeding the turbo cooled, filtered oil from the B&M oil cooler, so why not do away with the stock turbo water lines?

Imo cooling with water mitigates the heat soak better than just oil cooling. I found out how easy it was to boil oil with my b16g, and I had both lines to turbo.

Your gonna wanna keep the turbo water cooling lines, for more reliability it helps.
that the oil is cool, but remember the oil has two jobs at that point lubrication and cooling, and motor oil does one of these jobs better then the other.

Exactly correct. Although the oil is cooled down some, generally it's purpose is not to cool down the turbo, it is to lubricate the bearings.

The coolant lines however go through the correct passages to cool down the turbo like it is meant to. That being said people have been known to disconnect them and be fine, but you have to make certain precautions.

not sure about MHI chra's but others perform just fine n dandy with no water cooling at all. Now that doesnt mean do a 30psi pull right in to your driveway and shut it off, you let non-water cooled turbos idle down for 2 minutes roughly. Honestly unless you drive like a mad right up to your house you dont even need to idle it for any longer. Usually the cruising/off boost/stop n go driving you do on your way back(if you live in a town) is enough to cool the oil down thus cooling the turbo down enough. Especially since your running an aftermarket oil cooler.

I need to check your mods list to see what turbo you're running i guess but even with mhi turbos people have blocked off the water lines. Been done plenty. PTE (say what you will about their QA) doesnt have water cooling provisions on a lot of their turbos. There are others as well that do not.
