I have driven a 90 Accord for most of my driving career. Now I am probably going to purchase an 89 civic hatch. I want to know if the DX D15 motor in there is going to be a 16 valve engine or does it have less valves than the later models?

Peace*
 
That's what I was thinking as well. Thanks. I also have a second question about this. I was reading the "HF Monster" article and I was wondering if I put the intake manifold, dist., and ecu off of an Si will it yield the same results? I would just keep the DX tranny since this would just be for temporary increase until I get the ZC engine.

Peace*
 
will it yeild the same as an Si.... not exactly. The Si cam is bigger and if I'm I not mistaken the springs are a little stiffer. What will change is your rev limiter, a slight bit more hp and that's about it. it will still be a 1.5 still too. but those parts are cheap and you have to convert to MPFI anyways so you might as well do it.
 
;) Dident some of the early civics have 8 valves?
I think its the engine that has a 7 at the end of the engine code.
And I think the 16 valve engines say 16 valve on the cover.
 
the 88 to 91 hf models were 8 valve and 92-95 cx models were
