just cos it got big valves dont make it the best spa.
give us proof.
Plus, if Mi16's was soooo good wouldnt people be fitting them in kit car and not red tops or z-tec's?
sorry i am an x-pug boy (once owning a Mi16x4) and i think the red top motor is far far better IMO
it has more power as std.
and you can get 240 bhp on iTB's ( u dont see my n/a vw's breaking 200bhp!)
