looking at total impreza and owen turbos are doing a ported vf34 for 370bhp so good performance and quick spool of vf series any alternatives 18g seems very good for the price but some say slow spooling

I was told befor i bought mine that 1.35 bar is @ 3k not fitted yet so Dont no, i also will be getting new ported header and uppipe.

 

my 18g spools more or less the same as the vf35 that was fitted as o/e. No noticable difference at all in spool at all

 

thanks
martin
