i ran into a problem on my civic engine its a 98 Ex has a D16Y8 engineand i am kiend of low on the money and i wanted to buy a engine from 1996 civic dx that has a D16y7 and that guy told me that its not going to work in my civic so i am confused now, can someone help me? i have the tranny still but i dont know what kiend of engine i can put on.

 

A d16y7 will work, but you'll be losing performance (lower power and no vtec). If that's ok with you, then throw it in. You should be able to find either a D16y8 (96-00 civic ex) or a D16z6 (92-95 civic ex) for a few hundred pretty easily. They're both d-series (so they'll work with your transmission) and they're both vtec.

 

what about the ECU do i need to replace that too if i put a d16y7 non vtec

 

yeah, if you get a y7, you'll have to get the ecu to match.

 

what about if i get a 95 ex can i put the intake maniforld from a my 98 ex because i want to make it look the same as 98 ex?

 

z6 intake manifold might be better from a performance standpoint and your car will not pass emissions with an engine in it that is older than the car itself so be aware of that if you have emissions tests in your area. Also I want to point out that the D16Y8's from the 96-98 civics are not the same as the D16Y8's from the 99-00 civics. If you get the D16Y7 all you also need is the ecu.

 

ok if i put the d16y7 into my ex can i put the intake manifold form my d16y8 because they are different

 

You can, but there's some sensor you have to change or something like that. Also, I think you'd need to change to your y8 throttle body and intake.

 

alright thanks for all the info. now i wanted to ask whats a better deal a d16y7 with 140k miles for $300or a d16y7 with 82k miles for $550. is 140k miles a lot for a civic engine?

 

140k is nothing for a honda engine... provided it's been taken care of, of course
