i have a jdm h22a and it says is a 91 but didi they make 91 h22a dohc vtec and what r the specs on the motor.

 

Yes they are a few out there that are stamped 91 on the head...I have seen 2...the specs are the same from 91-95 jdm h22's. I did notice the 91 and 92 years that I saw didnt have a map sensor on the TB also didnt see any intake manifold brace...
