i don't do rebuilds so i don't know for sure, but afaik, the blocks and
heads are identical. the crank is slightly longer stroke [to give the
extra few cc's of capacity] and the cam is a little more punchy, but
other than that, they're the same.

define "professional"! if you've had this crx for a while and know its
history, stick with it. otherwise you have no idea what you're getting
into. the most important thing is to find someone to do the swap that's
not going to rip you. by the sound of it, half the stuff you've just
mentioned is coming from a source that's trying to set you up to put
their kids through college.

find out if the zc will pass your local emissions laws, then do the zc
swap. that motor is cheap, hella fast [160hp from a 1600 motor], and a
straight bolt-in. then you can keep everything else. and be careful
who you ask!!! talk with a smog person. here in ca, we have "test
only" stations that are forbidden to do work on the vehicles so have no
interest in trying to sell you on stuff you don't need. my local guy is
a honda fan and was delighted to me about what i can and can't do for
egr systems if i want to do mods without getting the vehicle refereed.

one last thing: if you want to be cheap, just get the si cam and swap it
into your d15. you're only losing 97cc's. you could probably do that
yourself. better yet, get an hot aftermarket cam. no problems with
a/c, vtec, transmission, mounts, etc., etc. do it with the engine still
in the car.

Well, in that case...JHMED9364LSxxxxxx.

And to answer the question you asked in your other post, I am in the US.

First Google result for "Honda VIN Code",
http://en.wikipedia.org/wiki/Honda_Automotive_VIN_codes,
indicates that this VIN is a 1.6L CRX Si built in Suzuka, Japan. So it
appears that, at a minimum, the block was swapped out at some point.

1990 Honda CRX
D16A6 SOHC 1.6 engine.

This vehicle does not appear to be an Si, but I could be wrong. I believe
the Si would have a "7" where you have a "6"..

Re: My Si has a DX motor!

What's the difference with the Si? could you just get the "Si" badge on
ebay or something and just stick it on?

no, as the op said, it's got rear disks and it's 4pfi. the only thing
that's not "si" is the lump under the hood - all systems are present and
correct by the sound of it.
