Garrett Turbo, has anyone used one of these?
 

Can anyone help me out, I came across this turbo and was hoping I could use it on a 13b Turbo or maybe a 20b?
If it's possible, what size compressor wheel /exhaust wheels do I need to use?

1.15 and .72 may be a little laggy for a 13B, but would kickass on a 20B. That turbo should put up some good looking numbers.
