Proper Oil Lines For a 1G

[jmorri15]

so i took the turbo out to do some work and i noticed the top oil line is a tiny copper line running from the top left of my engine block and then a large return line to the oil pan. now according to what ive read on a 2g car the feed line will be running from right beside my oil filter. for my 92 gvr4 what should the right setup be. oh and im running a greddy 18g so its slightly larger then stock.

What you have sounds like stock 1g 4g63 setup. The oil feed line into the turbo comes from the left side of the head (like you said) and then the larger return line to the oil pan. Some people relocate their oil feed line to come from the oil filter area (from one of the oil pressure ports) so that they can get higher oil pressure to their turbo (oil pressure in the head area is lower than block/oil filter area). Your setup seems stock so as long as your turbo is okay and there aren't any (many) leaks, you should be good!

I put the relocation feed line from the oil filter housing to the turbo. After a 1,000 I had a leak. Figured it out and was rubbing on a metal piece on the fan. Didnt know it could rub through braided stainless steel.

I would run it off of the head like a stock setup, especially if you have the balance shafts removed, then the oil pressure will be much higher at the OFH.
