Turbocharging a B18c1

[Flips]

Hi I am new to the site and new to honda but not new to boost. About to buy a B18c1 and wanted to know if putting B18a or B18b pistons in the block is a good idea in order to try to drop the compression ratio. Also what compression ratio should I expect?

if you have the block i sugggest resleeve if u have money. or go forge rod and piston 9:1 if u wanna boost more

Keep the gsr motor and boost that, they handle boost pretty good, and as for compression the cyliners shouldnt be more then 10psi apart.

Op wanted to know compression ration not compression test.

Keep the gsr pistons and boost it. Forged internals are a good idea if you are going to resleeve, if ou are going to keep the stock sleeves, then keep stock internals. Forged pistons have a tendency to expand with the amount of heat that is produced and shink again once they cool
