oil/water feed questions

[festyfreak39]

Hey all, im super close to finishing my bz5t (what im callin it) but i have a couple q's

1) How big does the oil feed line have to be, is 3an ok?
2) do you absolutley need to run water lines? i never did on my miata turbo and it just ran fine

thx.
Julian.

The -3an is ok, I run an .060 restrictor though (.030 with a ballbearing turbo). You know darn well what the water will do for you. It's easier than you think, pull your source from that little in and out 4 inch rubber hose piece that comes off the water pipe right by the gauge temp sender. You couldn't ask for a closer, more correctly sized location.
