Alright, i know ppl are gona say search, but i did, my question is what is the total difference bettween the zc and the 88-89 teg engine, ppl say the mounts are different, i thought all d series bolted right into the CRX. Other ppl say the teg engine is just a detuned ZC with less agressive cam and lower compression, The ZC and teg engines have interchangable parts too?? so if someone can shed some light on this subject for me

 

anyone have any clue what the difference is??

 

Some of the parts are interchaingible i think, but the valve springs are wider then the ZC ones. I took one apart and it's a PITA to work on those heads (removing the cams and rockers to get to the head bolts is not fun)
