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....

 

anyboyd?

 

You will need to use a modified Honda headgasket or a Cometic headgasket. Either one will need a 85mm or 86mm bore depending on which bore your block is.
As long as you have to go with aftermarket pistons you should go with new con rods as well. Eagles are a good economical choice but Crowers, Manley, and others will be good choices as well.
About the 8500 rpm rev limit; engine main girdle, blueprint, balance, con rods, and proper tuning........ you will be fine.


**dang 86mm is some big bores for a street engine, I've never wandered past 84.5mm myself**
