dont quote me on this but its .03 if its a GT spec ball bearing turbo and a .06 if its just a normal t25/t28...

0.03 unless you want to blow a seal on your bb turbo!!!

do you know why its .03 for the spec r or is it .03 for all bb turbos...wtf!!

IIRC all ball bearing turbos require smaller oil restrictors than do journal bearing turbos.

i doubt the stock banjo fittings on the hard lines of any sr20det were .03 restricted

yep 0.03 is what i though!!!! just wanted to make sure... Thanks guys
btw, 0.06 is 4 t25/t28 and because the spec r is BB turbo thats why it needs a 0.03

spec r is dual ball bearing...maybe thats why its .03
