did you ever try using one of those gauge kits made for running the fluids into the cabin? You can use it in the same way but remote mount the sender on the firewall or something.....

I have my oil pressure sender remotely mounted on my firewall fed by a stainless braided line from the tee I have at the factory oil pressure sender location. You don't want to mount it directly onto the block because the vibration will inevitably ruin the sender.

dont you guys think 50 is too thick even if your running a turbo setup?

thicker oil = less horsepower and higher temperatures right?

wait....you have your sender remote mounted and the fittings still broke? Or did they only break when you had the sender directly attached to the block....

They broke when I had the sender mounted on the block. When I switched to steel fittings the issue was resolved. I later remotely mounted the sender, but after a month or two. Steel or stainless steel fittings are the only way to go.

True. But thicker oil also ensures proper lubrication to the engine after the oil has thinned out from also lubricating a hot turbo. The 4G94 oil pan is ill-designed and doesn't maintain good pressure on oil that's too thin from adding a turbo. An oil cooler is a good addition to any setup and aids in keeping the temps down and pressure up.

I'll soon be installing my turbo. Will it be okay to use 0w50 full synthetic?

Try it and let us know how it goes. You should be fine. Keep track of your oil pressure when your engine is warmed up and where its at during and after WOT.

Hmmmm.... I guess this whole oil argument really depends on where you live.... Read the chart in your manual for the specs on different recommended ?W-?? Colder temps usually use 0W or 5W but those same ones are also used in normal temperatures in which a thinner oil is recommended to increase fuel economy. So a 0w-50 will be thinner than a 20w-50 at startup(which shouldn't really be a problem)

I changed my oil yesterday and switched over to a 15W40 to see how it would affect pressure. My oil pressure dropped about 5psi at running temp and now sits around 10-12psi. This is still within spec to the Mitsu service manual which says pressure needs to be above 3-4psi at idle, IIRC.

let us know if you switch to something thinner

I'm surprised at how heavy an oil turboed lancers need to use, I use a 10w30 on my car and at most can move to a 10w40 if I'm really hard on it or live in Arizona.

After I drop in my new engine I'll be running 0W50. I don't think we can run anything thinner than 40 and still have adequate oil pressure. I wish someone could figure out what the design issue is with the 4G94 oil pump that prevents it from working well with thinner oils.

i want to run 0w50 full synthetic also when i install my turbo kit, but i dont have an oil pressure gauge

If you're gonna install a turbo kit on your car you need to make sure you have the proper gauges to monitor your engine's vitals. Just a thought.
