I've been trying to figure out how to add a twin turbo system to an H22 for my 90 Honda Accord. Could anyone give me some kind of instruction if you've done this yourself or know some one who has made this type of modification.

 

I dont think an h22 could handle a twin turbo setup haha, this sucker isn't a supra

but to answer the q, I have never seen a twin turbo h22

 

twin turbo 4 cylinder?

good lord why?

 

Twin turbo setups hondas are rare for a reason. Its not really worth the trouble.

However, If you really want to do it i believe there is a guy over on homemadeturbo that has made one for some type of Honda motor (I can't remember what type I think b or d) but it may be able to give you some guidance.
