I understand. But some people know the specs of turbos like none other and can tell me that'll spool quickly or is too large for my engine application and will spool at 5k+ and is pointless. I just dont want TOO small of a turbo or TOO large.

-Ant.

edit-also on some turbo there is a bolt or nipple on the intake side of the turbo. I saw pics and there is a vacuum line on it but some other turbos dont have that..... damn this ish is confusing.
