is there a difference betweent he oil line fittings for the smaller turbines (T25..14B..etc.) and the larger turbos..like a SC63 T3/T4?

i have an oil return line from a RevHard Stage2C kit that I got from my friend (he upgraded to stainless steel line on his integra). can i use it when i go Ghetto boost?

 

T25/14b are a tad smaller than the T3 turbo return fittings. Basically you just want a large enough hose that will slip over the fitting on the turbo, and a big enough fitting in the pan (above oil level) and you will be fine..
