Greddy T88-25D... equivalent std AR number?
Hey... i wanted to pick up a GT40 (88) w/ the 1.19 AR exhaust.
but my friend just said "buy my T88" so i asked him what size his exhaust was and he said "Its a 25D"... and then i said "****... its a mitsu housing... its a Greddy turbo, aint it... not a garrett/turbonetics..."
my problem is, the 25D exhaust housing makes no sense to me, i have no concept of what it equates to in Area-to-Radius ratio... the 25D figure is simply the area of the turbine housing... 25 sq.cm
anyone have any clue as to what a 25D housing is close to in AR ratio?

I have never heard of a 25D exhaust side unless its a 25G off a Greddy T67 which would make it a bit smaller than a T60 exhaust side with a huge compressor which doesnt make much sense. If its a stock T88 33D or 34D then I would guess the A/R would be around 1.05-1.20 comparing to T series turbos. I would much rather get the GT40 over a T88.
