I got a 42mm chinese ebay one. http://www.ebay.com.au/itm/190700402072?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
fit straight in perfect. stock fan, shroud and sensor no problems. didn't check for current (forgot)
Using Tectaloy 50/50 premix with glycol (or whatever it is. i'm tired and cant be bothered to think, lol)
Gave the pod filter a good clean. DAMN that thing was filthy!!!! and made a new bracket. to hold it in place nicely..
Now just waiting for boost gauge to start next step =)
