hey guys. I am thinking of doing a turbo build with my b16a sometime in the future. maybe even k20/24 turbo. I was wondering what exactly causes changes in the compression ratio? I hear that certain upgrades are only good for n/a builds.. lets say i was ballin out of control and could make it rain like niagra falls. what would be the best build?

 

Compression ratio all depends on static compression of your pistons i.e stock b16s are 10.6:1. By purchasing aftermarket pistons you can select your Static Compression Ratio, most go with 9:1 which allows for good numbers on pump gas. Also headgasket, head, effect compression ratio. By the head I mean if you run a b16 bottom end with a GSR head the compression increases because of the size of the combustion chambers in the GSR head.

This site helps out with all honda motors using stock pistons n such.

Hope this helps.

 

super helpful, thanks! I'm goin to have to mess with that from my computer at home.. but for now, how about headers? is that an all motor thing? I hear itb is for na builds as well? why is this true?

 

you also dont have to drop compression to still boost the b16. your weak link the in the stock parts is the pistons being cast they dont hold up like we all wich they would. you can stick with 10.6:1 compression ratio with an aftermarket piston and be just fine with a boosted application, you wont be able to run as high of a boost pressure but it will produce the power reguardless because of the higher static compression ratio. pump gas on a good tune can handle 10.6 no problem with a good piston/rod combo and a good tuner

 

Yeah personally, I am running a Stock b16 on 9psi. Runs great! Good luck with whatever you decide to do.

The main problem with stock b16 pistons are the ringlands. They are notorious from cracking and causing blowby.
