Alex_X93 Vw caddy tdi Sep 27, 2008 #1 Need to find out standard ph1 throttle body size/diamiter pls??
Alex_X93 Vw caddy tdi Sep 28, 2008 #3 Im guessing internal. I was told about an inlarged 64mm tb but unsure on original size?
Alex_X93 Vw caddy tdi Sep 29, 2008 #6 Thanks for above input seems 60-62 would give a 2-4 mm diameter increase over original?
M mini-valver Sep 29, 2008 #7 Yeah, the restriction is the inlet tract, not the size of the TB. The S1600's make 220 bhp on a 60mm single TB.
