for those wondering like me well why dont I try swapping on a op6 housing onto my stock rb25 turbo
don't (well get a turbo shop to do it for you)
I managed to knock the vg30's rear wheel off when I was removing its rear housing
so asked the guys fixing my head to put the vg rear housing on my 25 turbo for me
only if the felt very confindent seeing as what had just happened to the donor vg30 turbo
picked up my car from the mechanic got one free rev to 3,000 out of it and bang (whistles, looking around from mechanic's)
I wasn't going to bother discussing causes with them
we all know why it let go and they weren't going to be coming to the party
5 hours later (thanks to Huddy and Jarrad) I now have a stock op6 vg30 turbo on my 25 and it is awesome cars got alot more top end than before
however Ive also gone from a 1.5mm h/g to a 1.2mm h/g at the same time so I cant honestly tell you what turbos and whats comp ratio
the vg feels alittle laggier 200 rpm max only though (the higher comp ratio maskes it though) and now pulls cleanly all the way to redline which it didnt before
got a bit dull after 5,500
ps my led taillights and ganadors look phat !
sorry for the long post
