Hi, i have a tired 1.7 and am planning to build a 2.0. My question is, what size oil lines can the oil pump handle if i mount an oil cool in the front trunk?

-10 or -12 lines will work with a TIV motor with a high volume oil pump just fine. The most restrictive spot on most of these front oil cooler setups is the pancake oil filter adapter and the associated fittings. That is where I have seen the smallest orifaces in these setups.
There may be some pressure loss due to line size, but real world experience shows that any pressure loss due to line size appears to be made up by running cooler (higher viscosity) oil through the engine (which raises the oil pressure). When we ran with a TIV in the track car with a front mounted cooler, we used -12 lines because that was what was recommended by other 914 guys 19 years ago. We had no oil related problems in the time that we ran the car in that configuration. (2 drivers, track only car). If I was going to recommend line size, I would go with -12 line. |
