i was reading a thread the otheer day and someone asked what the best d series engine was. someone mentioned the d16y8 and the d16z6 were the best. someone else said that the d16z6 was way better. can anyone explain to me the differences? i know they have the same displacement, both sohc vtec. d16y8-127chp max poer @6600rpm. d16z6-125chp @6600 rpm. i dont know the torque curves or how the compare when modified. anyways, just curios. also, how do i know what kind of model civic i have(eg, etc) i have a 97 civic ex

 

you have the y8,

 

i know that i have the y8. im asking what the difference is between the y8 and z6. perforamcnewise and how they react to performance parts

 

one head fows better, the other's intake manifold flows better, etc. Just little shit that gives the y8 2 more hp... OOOOOOHHHHH 2HP!!! pfffft
For the sake of making life easy, it's the same ****ing engine, stock for stock...

 

Y8 = OBD2
Z6 = OBD1

 

Do you mean what chassis code? You have a EJ8

 

its pretty much the same engine. OBD1 cars supposedly react a little better to tuning, but that may just be a myth.

 

I have a Y8, but I'd rather have the Z6 (with the same mileage )

 

Ehhhh I dunno. Tune your 92-95 motor up all you like, I'll stick with my y8 anyday, I fear high-milage engines

 

Lol you guys are to much !
