it would be an excellent turbo with the mods you have right now
Unless you are planning on running 150 or larger injectors don't go any bigger than a 64, all you will get with anything larger than a 64 is alot of smoke trying to get up to speed as you will not have enoug fuel to spool it up quick enough. what mods do you have? i am running a 64 and drive it everyday.
Are you saying that you run a 64 in the top post and a 62 in the second post? You sure can change a turbo fast...what mods do you have done? I'm running a 62, unless you are going to run 100hp injectors or bigger 64 is not going ot help, just going to make alot of smoke. let me know what you are looking to get out of the turbo you want to buy.
