i was wondering if a 20b block with a 16b head would work i was going to swap it into a 626 but seeing how it is a rx7 motor i thought i would ask this question in the rx7 forum so if you can help me please do

 

I misread your other post. I read 16b and went straight to honda motors(b16).

Anyways, I think that you mean 13b and 20b. Both are rotary engines, one two rotor and the other 3 rotor. I'm not sure what you mean by head though. The rotary engine has no head since it lacks valves and cams.
The swap would be awesome, but not logical. It could be done with enough money, but you could buy a second generation turbo rx7 for a cheaper price and have a rwd car with a sports car feel. I, personally have always wanted to swap a 20b into a familia gtx, but it's just not logical.

 

Idaho aye? I grew up in Boise. Anywho. I don't know what you mean by "head" as well. Rotary motors are headless. a 20b is rare to find. You have to use a 3rd gen tranny to mate with it. Other that that Everything is possible. What car are you thinking about putting it in? A kid in Boise/Nampa area did the swap into an FC. A guy here is Salt Lake did the swap into an FD. Don't get just any 20B though. There are certain vins you want to look for. A and B vins are not the best. Just an FYI
