Re: too big for z6?
 

It's a good size, I personally prefer some lag. I'm running a t3/t04b on a stock z6.

Re: too big for z6?
 

i dont think its too big itll prolly have a decent spool nothign ridiculous

i wouldnt go much bigger unless of course your planning on revving the piss out of it and want a laggy turbo

i say go for it
