Vtec didn't come out till the 5th gen. 94-97. the 4th gen 90-93 never had Vtec..and all were SOHC F22A's. Unless you had the Accord Euro, which came with the DOHC H22A

 

I forgot to mention that the engine I have was jdm. it was swapped before i bought it. i did'nt realize that the non vtec heads could do better. what do you suggest upgrading besides the cams wihtout boosting it? i dont really want to boost because its my daily driver.

 

^ I wouldn't even bother touching it at this point. Just drive it and enjoy it.
