oil feed line

[nboost]

Just curious on what size the oil feed line to the turbo should be? does it matter?

The oil feed line on an intercooled TR is 3/16" O.D. A larger line would reduce the pressure, a smaller one would reduce the volume...I'd stick with the original size for a stock or mildly modded car.

Actually it's 1/4" OD ... just verified by slipping an open-end wrench of same size over the tube. Don't go smaller.

The overall restriction is the turbo's bearing, so it's unlikely there'd be any benefit to larger tube (less restriction), all else being equal.

thanks for the info
