hey sup fowks i got some questions me and my buddy jimwhy are going to do some frankenstein (mispelled) engines u kno B20 block B16 head. What are some problems that you could run into? also what type of transmission would you want to do. And the final question how many psi could i safely run on a B20 block with a B16a1 head

 

all this really depends on how hardcore your going, usually with a b20/vtec setup you have high c/r. and you probably know that high compression is the biggest enemy to boost. so if you are planning on doing a boosted b20 vtec you are kinda wasting time and mone on building the motor out of parts off of different motors. the b20 block is one of the weakest honda blocks and will desperately need to be sleeved. in my opinion you should just build a b18a/b/c whatever you want and you wont have to go through the hastle of building the motor like a b20. the b20/vtec setup is normaly a N/A setup so I would say either go all out turbo or all out N/A because doing both on the same motor isnt the greatest idea.
