Quick Turbo Question

[KTS]

1) yes you can but do it neat if you decide to as any tape that blocks a passage can be the end of a turbo or even the engine. There is a liquid thread seal that can be purchased that works good and will avoid blockages. Those couplings/fittings are designed to prevent leaks.
2) I have no idea wish I had a turbo vitz to tell you. You wud need at least a 2 bar map sensor (1 bar vacuum and 1 bar boost) wired to your management of choice and the clip the MAF sensor voltage at atmospheric pressure.
3) Use the same oil you usually use. Turbos are designed to be used with a wide variety of oils. What is more important is using the correct oil restrictor for your turbo. Too much or too little oil pressure to a turbo is what destroys the turbo. Your turbo looks like a chine turbo therefore you should prime the oil system before starting ( unplug all coils and injectors) and tumble the car with the oil return disconnected. Then start the car only when oil drains from the oil return line. This will ensure that the turbo is receiving oil. When I had a chine T2860 turbo I had a radiator repair place weld close the oil supply banjo bolt and then I re-drilled a smaller hole to limit oil pressure to the turbo. Garrett website indicates the oil restrictor size for journal and ball bearing turbos. Or contact the turbo supplier and ask them if a restrictor is needed then ask them again lol.
Sorry I think I got carried away. I just miss having a turbo charged car and remembering all the little projects I had to do.

Thanks much, I'm using a t25 banjo feed kit so I'm hoping it already has the required oil restriction

Most of the banjo feed kits do have built in restrictors, but they typically are offered in separate choices of 1.5mm for journal bearings and 1.0mm for ball bearings.

Do you think I'm safe with mine? another question, what's wrong with running the return line to the oil pan?

Just check the size of the hole in it. If it is too large then you maintain pressure through the turbo, which can cause oil seepage through the bearing and hence smoke out the exhaust. The return oil line can also cause the same problem if the oil exiting meets resistance (like pumping up through a puddle of oil). That and frothing of the oil are why you want the return above the level of the oil in the pan.

Oh darn, that sounds terrible. Would I need to take the engine out to drill into the upper oil pan assembly?

I'm also looking for a base tune that has the maf clamp already set up for the F/IC 6

With a right angle drill you should be able to do it in place. You will need to remove the oil pan when doing so to make sure you don't have any metal left behind.

For the MAF clamp it is best to follow the procedure shown in the F/IC documentation for doing so, as your air intake setup may provide different readings than on another car.
