Originally posted by BigBald There are two 20g turbos....the beteer of the two is the TD06H 20g which is also the bigger one. Yes there will be a spool difference between the two but i am not sure as to how much. The TDO5H 20g is the smaller more inefficient one. But that of course is my opinion based on people i know who had that turbo.
I actually have both of them, but the one on my 4G63 is the TDO5 with the 7cm housing. The guy before me thrashed on it for over 6 years and you can tell by the dyno post below (not tuned).
On my 420A, I have the Hahn S20G with the 10cm housing and It spools up so much faster than the other one and plus it is almost brand new..
