i bought my turbo kit used and im new to the whole thing, it didnt come with oil feed/return lines. and i was wondering where to run the olines to?? where is a good place to purchase them ,and do you have a part number or anything??? pics too if possible..
thanks very much im going crazy!!
I was sure this had been answered before, and I was trying to dig up the posts so I could simply provided you links to them, but I'm not finding what I am looking for, so.....
The oil supply line requires attachment to a source of pressurized oil in the block. Most people simply put a "T" on the end of the spacer that the oil pressure sensor uses to attach to the left front (driver side) of the block. This allows for the sensor to remain functional, while providing oil.
You route the line however you feel like routing it, so that it is safe from damage.
Oil supply lines are usually small (-3AN or -4AN) steel braided or small copper (bathroom plumbing) or steel (brake/fuel) hard lines in a 1/8 or 3/16 (roughly equivalent inside diameter to -3AN and -4AN respectively).
Type of line used is generally dependent on budget, durability desired, acceptable appearance, etc... of the user.
Performance shops (ie. Summit, some local shops depending on locale) are good sources of steel braided lines (AN's) whereas everyday parts and hardware stores can be sourced for hard lines.
Fittings are always the fun part of the puzzle, since there are multiple different thread subsets, so going from one measuring scale to another requires attention to detail.
Many people will advice the installation of a compact filter near the turbo, many people ignore this, many people do not, there are security benefits to running an inline filter at/near the turbo, but it in the end it is up to the user.
Connecting the oil feed to the turbo sometimes requires special fittings/adapter plates, other times you can simply screw a hose fitting into the inlet. Depends on the turbo.
Sometimes a .040" - .060" restrictor is required on the oil feed, sometimes not.
Oil drains should be around a 10AN (1/2") and should also be connected to the turbo according to the design of the turbo, and the drain should connect back to the engine at the highest point on the oil pan that you can connect it. It is technically possible to drill and tap the timing cover for a drain connection, but it is generally easier to attach the drain to the pan. Drain hoses can be made of any oil compatible material of adequate diameter.
The oil drain must be rather smooth in curvature from the turbo to the pan, with the line as vertical as possible.
Drain lines connected to the valve covers, oil pan drain plug, pressurized oil passages in the block, oil level sensor, etc... will not work, at least not without separate catch cans and sump pumps, etc.....
