it's great I suggest anyone to buy it, greatest mod ever, blew my engine conversion out of the water, pfft **** DOHC 1.6l b16 I'd take a carby and 4 of these mother ****ers any day of the week, hell I'll even weld some to my rocker cover and get another 60bhp !! mother ****er that's better than a turbo ! Get one like I did, I crap my pants every time I step on the gas, I almost ran a cat over in reverse cos that's how much power it has !!!
