i need help. i have a 1991 honda accord ex two door coupe with five speed and vtec motor in it right now. i was looking to see what the code on the motor was and it is just F22B. all the research i have done said this motor was used in 1994 or later cars. Any help would be of great help

 

Swapped by a previous owner?

Normally a USDM engine has a number after that, like F22B1. Without that number, it might be a JDM engine.

 

what is USDM and JDM. i just wanna know so when i order cold air intake and headers, what to get?

 

USDM = US Domestic Market = car that's built to be sold in USA.

JDM = Japan Domestic Market = car that's built to be sold in Japan.

USDM cars might be actually built in Japan or Canada, and JDM cars might be built in Ohio. JDM & USDM means the car complies with the laws of the destination country.
