Default Just looking into the future.. but need help with this..

A b20 bored and sleeved to 2.1- 2.2 liters (i believe its 85-86mm). What problems will i have with the head (B18c5 head), If i do all the stuff needed for to make the nonvtec bottom end + vtec head work properly... Im not asking about the actually process, or the parts needed just for the nonvtec bottom on the vtec head. I am asking if the bore size is gonna have any effect on it?
Will i need custom head gaskets? I know ill need custom pistons, valves, what about rods?

thanx alot,
Jordo

ps: what else would be effected? would the rod ratio be to horrible to rev to normal 8500rpms....


Would it be cheaper/better just to get a gsr block and bore and sleeve to 84.5mm??

For a head gasket, use a bored stock head gasket or Cometic.

You can use shelf pistons, factory valves, and shelf rods.

Depends on who you ask.
