Post Looking to buy a b20b

so ive been looking at b20b engines for a civic ex coupe

is it a bad thing to buy an engine that says "Jdm Honda B20B 97-01 CRV Low Compression Engine DOHC 2.0L Engine Only"
or high compression. just curious because then i wont even consider them as an option to buy ill go with one that doesnt say high or low compression

going for a budget turbo build!!
thanks in advance

Re: Looking to buy a b20b

if you're turboing it you want to start with the low compression engine

Re: Looking to buy a b20b

so the low compression or high compression labeled in the sales posts arnt a bad thing. got it. start with a low compression engine what else would you recommend doing before just throwing it in and tuning it all up

Re: Looking to buy a b20b

There's a difference between "low compression", as in the rings are failing, and, "low compression pistons" where the rings are fine and the piston/rod combo is setting a desired lower compression.


Its safer to test and tune a boost build with what would be considered low compression pistons for a N/A build.

Stock N/A for generation is around 9.5 parts gas to 1 part air, N/A. Or 9.5 : 1

Generally to boost a car people drop the N/A ratio. My pistons for example are 8.8:1.

Re: Looking to buy a b20b

that makes sense but these sale postings just say low compression or high compression nothing about low or high compression pistons and ive done some research along with a few hundred civic build youtube videos and im only planning around 3 to 400 hp at the start some guy did a budget build with around 3500 so i iwas kind of setting my budget up there for now and slowly build it.

but ik that the b20b is a better engine to start off a build rather then the b18

so im mainly just confused about the sale postings since they say nothing about low or high comp pistons just say high or low compression

Ask the seller what is meant by that.
