mini-me/frankenstein

I was just curious in making a mini-me/frankenstein and I wanted to know, if I were to take the B20 block from the CR-V, what head would fit on it or which would give me the best results ex: B16A, B16B, B18c etc. (note: it will remain naturally aspirated) I don't know anybody with this swap so I really have no clue how it peforms what so ever. As well I wanted to know, do I need to use teh crankshaft. the pistons and the rods from the B20 or from the b16 or B18 or wtv I end up using??

best head for a b20vtec would be the GSR not as pricey as the ITR better then the b16a.
I have a lsvtec *pretty much same idea just b18a/b block* I love it faster then my cammed bolt on GSR swap will last forever and makes good power very linaer.

I had a great builder and knew what i wanted out of the motor before i picked up a wrench those are the real keys with the frankenstien motors.

but if I put on a GSR head, does that mean I need to put the GSR pistons and crank or I still use the B20 crank and pistons?

you can use b20 crank and pistons or gsr pistons or custom parts.

I dont have my comp calc with me but depending some will put your comp too high or too low.

well then im guessing that if I went to some place to get high compression pistons, would I get GSR or B20 pistons, I would guess B20 pistons because then teh compession would be to high??
