b16 pistons in a b18

[dc4dude]

i have a b18b1 in a 97 integra. i have a set of b16 (pr3) pistons i want to put in the b18. what mods do i have to do in order to acheive this? do i just toss them in? rods and all? what compression ratio am i going to be looking at? i am keeping it non-vtec, not looking for crazy power, just a little bump up in compression. any help or direction you guys can give me will be greatly appreciated. or if you can refer me to a link where more info is available... whatever hepls. thank you and have a great day.

you need to use the ls rods and im pretty sure they have to be machined to work with b16 pistons. check me on the milling part as i've been out of the game for a bit.

no mcahining required. ls/b16 pistons are interchangable.

cool, well that's a relief. now on to the compression... what kind of numbers am i looking at, and will the factory ecu work with this setup? i have type r injectors for this build. and thanks again guys.

factory ecu will probably 'work' but i wouldnt use it if it were my car.
