RE: 20v BT valves choice
Stem and guide "work" together..... the same FSM lists maximum valve/guide clearance. I'd recommend using that before you condemn the valves.
Exhaust valve - 0.1mm (.0039") Intake valve - 0.08mm (.0031") If they still are too small..... the choice is yours... replacing OEM valves, with OEM can get pricey, or you go oversize with Supertech.... As to Supertech... OEM valves the intake stem is larger, but with the Supertech the exhaust stem is larger........ not sure why that is.... Dan - You can |  .... OR you can ask for help!!!OST Porting service - http://hachiroku.net/forums/showthread.php?t=19991 |
