hey guys, ive just put my turbo a15 in my car without the turbo, runs stock carby etc, and on my oil pressure gauge at ide which,sounds like about 1200 rpm my tacho isnt wired up coz i had to rewire for electronic dizzy anyways, it shows about 20psi oil pressure hot, but cold is like 50psi, but if i drop my idle to normal about 1000rpm, the pressure sits on about 12psi, is this bad or is this about right? will adding oil cooler make it worse or will it just need more oil to fill the system ??? im thinking maybe with oil cooler and turbo might be a good idea to machine meself up a l series/ aseries high volume??
