accord compression

[custom]

what is the accord compression ratio????

[MessyHonda]

9:3 for fuel injected and 9:1 for carbed...you are going to need custom pistons to get better compression...and they cost like 500 bucks

Can anyone confirm if the BT and 1988 A20A3 had 9.1:1 compression just like the carbed engines or were all EFI A-series 9.3:1 across the board?

I've got both an 86 BT1 and an 89 A20A3 at home.
