hello, I can put a head of B16A2 on a block B20A7?? which are the modifications?

 

the b20a7 im assuming is out of the old prelude si model, which i thought was a b20a5, but i could be wrong. Anyway, no. You cant do it. Dont waste your time.

p.s. i dont want all the DIY ****'s to come raining down on this post with "if you have enough money, anhythings possible." Lets just leave it at no. its not possible.

 

I can put a B16A in a prelude 3G??? which are the modifications to be made??

 

ill be honest and tell you i dont know much about that particular body style and the swaps that go along with it. I have seen an h22 done in that chassis though. Youd probably have some better luck in the prelude forum.

 

The older 88-91 Prelude B20's are completely different from the more common DOHC VTEC and B20B/Z CRV motors. You can't bolt a DOHC VTEC head onto the older B20's and pretty much none of the parts will interchange whatsoever.
