I am doing a custom turbo in my 1993 318is and need some help and some information to make things make more sense. Where would i be able to connect an oil line to the turbo? If anyone has pictures that would also be helpful thanks
It is a garrett .42 x .24 or something like that. I know that it is the stage 3 of the smallest turbo that garrett has to offer. I don't know exactly what it is. I am about to put the turbo on though and i need as much information that i can get though so anything you know would help a lot. thanks.
Are you talkign about the oil line on the turbo or on the car?
You are goig to need to tap into the oil pan to get oil. The best way to do this is to take the oil pan off the car. It's always a big argument whether or nto it is necessary to take off the oil pan to do this but you want ot make sure you dotn leave any shavings fromt he drilling in the pan. You will need to flush it a few times also jsut to eb absolutely sure. Remember that the oil return line needs to enter the pan at a lower spot that the turbo because it uses gravity. You want a clean straight slope from the turbo down to the oil pan.
actually, you want a high spot on the oil pan, so as not to have the oil , use its own weight, to push up the oil return line.
you want the oil draining onto the oil, and having no contact with the oil in the pan.
All turbos require oil, either a self contained oil or engine fed oil.
The turbo you have is either a Garrett T03 or a Mitsubishi TD04 and both turbos need coolant and oil lines. As far as the oil goes you can install a banjo bolt and fitting in place of the oil pressure sending unit then drill and tap the head of the banjo bolt then intstall a 90deg fitting then reinstall the sending unit. Then run the line to the turbo, you may want to put a restrictior in the line, that 2.2L turbo doesn't need but 20-30 psi. of oil. Too much and oil will blow past the oil seal and turn your car into a fog machine....
