Hey all....I was thinkin about puttin a new B20 in my prelude and then changing the head to a B18 head. Has anybody done this swap or know anybody that has done it? Also of mabe a good place i can find a nice B18 head? Thx for the help!

 

b20 is not the same found in the last gen of CRVs

So you cannot just slap on the head from the b18.

 

it has been done once to my knowledge.... which means if it has been once it has been done before.
thing is you do not want to attempt this unless you have a ubundance of cash on hand. there is a ton of machining involved.
once you are done you wont be any better off then someone whom puts a h22a in a 3rd generation prelude.
go turbo if you want to go fast for cheap in a 3rd gen.
