JDM FZ Engine in US 80?

[jaymar]

Is it practical to install a JDM FZ engine in a US-market vehicle (1995) and still pass muster with the Smog Police? What mods would this entail? I've never seen a JDM FZ, so have no idea... Thanks for any help!

Over the years, I have seen a couple of JDM FZs for sale here in Canada. Have no idea what would be required though for smog as we have no such thing here in Quebec, plus they implanted a ban of importation of RHD vehicles probably at least 10 yrs ago.

I would keep an eye on things like intake and exhaust manifold difference.

I recently dropped a jdm f23a into my accord in place of my f23a1 that was dying. The intake didn't have all the vacuum ports and the exhaust manifold was way different.
Also the crank and ps pump pulleys we're different sizes.

If it’s a COP motor it’s not happening without a lot of effort.

From this thread, I’m betting there are wiring differences at the very least. I wonder about ECM’s and such.

Suggest the easiest way to fix my hacked up exhaust?

Some idiot appears to have cut out the cat, welded in some tubing, welded up the bunfs for the o2 sensors and left them dangling. How tf am I gonna fix this without spending a fortune? Generic cat and have a shop weld in a wye pipe and some bungs? That's all I can think of

Does that mean police, or climate-friendly—or is it an acronym I don’t recognize?

I would strip the motor of the intake manifold and exhaust manifolds and install the ones from your USDM motor onto the JDM motor. Honda motors were a lot harder to hide from the emissions cops because the block/series was in plan sight. Obviously reuse your USDM harness and switch over the sensors or replace the sensors from the USDM to the JDM motor.

COP = Coil On Plug

Coil packs instead of distributor.

Ahhh, thanks. Didn't Beno find one of those, NOS, in the Middle East recently?

I did a year or so ago.

THank you I was trying to find a good picture to show the difference between a B18C and a B18C1.

Due to oxidation you can't read f23a but here's where it is, when in the car.
