Hi just a quick question... in my ongoing quest for more power out of my 2001 civic dx, ive come across the fact that none of the tuning companies are touching my D17A1 besides an intake and rear section exhaust and pullies.. i really want to convert to a vtec head off a 2001 ex. Does anyone know the engine code for the 2001 EX vtec?? where could i get the vtec head? i think everything else on the block is the same and stuff....
thanks

 

D17Y6? i think its y but not sure...

 

D17A2
