So unless your an engineer with a machine shop handy its not going to work out at all.

The electronics are complety diffrent as well. Its not a simple OBD-2 to OBD-1 harness converter. You would have to somehow mate the d17 with a d16ZC harness. In order to run a distributer ignition system but with d17 sensors

And if that somehow works out, you have to run a new fuel system for the new intake manifold you wil lbe useing as well, then figure out how to mate those sensors in, unless you manage to make a d17 manifold fit a ZC head.

So is it possible to run a d17 with a DOHC? simple anwser yes. Feesable? not in the least bit I would say your looking at about $25,000 to make something like that work. Thats if you DIY. And the extra maybe 10hp definatly would not be worth it. A built k20 turbo would be a much better choice for that kind of money, and you could also get some serious suspension wit teh left over cash.

So before you come in here talking like you know everything, stop and think that maybe some people here are pioneers to the d17 in the first palce and know what the hell is going on. Don't believe me in what I say? Rip your haed off the block and compare the blocks and heads of the d17 to the d15/d16. Nothing is interchangable with out alot of modification. and the electronics are even farther apart than the parts them selves. So unless your also skilled at creating custom wiring, sensors, circuitry, and programs, I seriously doubt you have the time skills and time to do somethign like that. I have a degree in electronic engineering and carreid a 3.8GPA to get it and I know for damn sure I wouldn't be able to create something that complex. It takes a team of hundreds of honda engineers years to make something like that.
