i didnt know some of that, that turbo that i posted up earlier in this thread, is that a big turbo or a small turbo... one major thing is i dont know about what size is small and what size is big, i will most likely side with the smaller one i just need to find out what size is considered small

 

Okay so i am aiming for .63 A/R and i found osmething like this: http://cgi.ebay.com/ebaymotors/T3-T4...QQcmdZViewItembut is that a name brand turbo or is it some knock off POS?
