which one? the 62 or the 64?

 

depends on how much HP you are wanting, 62 will go from 350-550. 64, for up to 600. the 66 will handle up to 700, however the 66 is terrable for towing since it will surge on you, the 64 has on some people, but not all.

or you can go for the silver bullet that can handle over 800hp.

now there are ways to make the 62 handle up to 700hp, but I would only use this if you were going to tow since it wont surge.

 

sounds like the 62 will do... I'm getting pretty close to having it run the way I want it to and would just want a tougher turbo so I dont break anything in the turbo.
