Hey I am new to this forum, but definitely not new to the car scene or forums...
Anyway, I have a 93 Justy and the motor just took a shit on me! I am looking to do some type of motor swap and have a d16 honda sohc available to me for next to nothing.
Just curious if you think this will work without having to completely rebuilding the engine bay? I know custom motor mounts etc will need to be created and thats not a problem, but has anyone heard of this being a successful swap???
What about electrical?
Any huge unforseen problems with this idea?
Thanks for your time!

Any huge unforseen problems with this idea? Thanks for your time! Byebeed, if you want to put a D16 into any Justy then it will have to be a wholesale power train implant. I say implant rather than transplant and will explain in a moment; but first let's talk about why it must be wholesale. What do I mean? Well if you were to try and adapt any engine to a Justy transaxle, the engine would need to be less than sixteen inches long from rear to harmonic balancer. This definitely leaves out any modern, Honda automobile engines. So, you would have to use a Honda engine and transmission together and mount them closer to the center (East/West) than they would usually be; which brings us to the implant part of it. When you do your usual Honda, Acura, Nissan swaps, you just drop in the new engine or engine/transaxle and then hook everything up but since the Honda is a wider car with a wider track, the axles will have to be shortened and you can just add that to the laundry list because you'd probably already be having a custom fabricator making hybrid Honda/Subaru specials for you anyway since the Honda axles are not likely to plug into the Justy's hubs. Next up, I assume the Honda uses a hydraulic clutch? The Justy does not. Honda engines of that era face the opposite direction from the Justy's engine which means there could be potential Clarence problems with the brake booster fouling your intake components. Speaking of brakes, this modified Justy with double the torque from standard is going to need much better brakes. I guess you'll be walking down to Kragen to buy one of their many big brake kits made for Justys. Ha, I'm just kidding, Brembo probably has one for Justys. (ha, I'm still kidding) Seriously though, this kind of conversion would take so long and the axles alone would cost so much that you're better off just fixing the Justy with a standard engine or better yet, buying a Honda. A Honda would be just as fuel efficient, quieter, smoother, more luxurious, infinitely faster, safer, easier for which to source parts and about 1000 times more reliable than a Justy that's been depredated with a D16.

not all honda's use a hydraulic clutch. some transmissions used a cable. makje sure you use one of those.
also you should use a stock ECU and wiring harness from the civic/whatever you get the motor from.
axles are easy....if youve never had one made you might think its hard but it isnt. you take the inner form the transmission of the donor motor, and the outer ends from the stock car and go to an axle shop and say "i need this inner and this outer and i need it this long" and they say, OK and give you a price. not that hard.
truthfully you are better off converting to RWD motor/transmission just due to space. its easier to alter the tunnel a little to fit the trans than it is to fit a wide motor in.
good luck

i love how you;re such a tool. I love how you assume that all Justys are 4X4 because you said it would be easier to just make his car rear wheel drive. What if his Justy is FWD? Then you still think that would be easier than an engine implant? Speaking of tools, I seem to recollect you giving English lessons all the while using 2nd grade English yourself. I hope your mirror is good & clean.

-off original topic - -- --- **streetruler**, I think it is a pretty neat suggestion to ditch the transverse mounted FWD. I am biased though, starting out as a RWD sub-compact racer . To further my bias, I would have picked the 1.6lt RWD out of a 67' Datsun 411 (or 510). I am not sure that the Justy 4WD rear end is able to handle the load if one were to try to convert the vehicle to be only RWD. I know that the 4WD design should allow full power to either front or rear wheels. The OEM FWD/4WD was designed around ~70hp engine power output. I am guessing that the Gen-2 Justy (FWD and 4WD) received larger front axles/hubs to help reliability. The rear drive in the Gen-2 did not get the axle/hub upgrade. I do not think the OEM 4WD rear alone could handle the power output of a 1.6lt engine. -hehehe just opinion of this tool -RRJ

I hope your mirror is good & clean. if its not a stock fwd auto justy you;re not interested. you provide no help and anyone that has an idea you just put it down because you know absolutely everything about cars. its so great to have you around. RRJ- i totally agree with you that the diff wouldnt be able to handle it. there is one kicker though....youd have to get the tires to stick a launch for that stress to be focused on the diff and axles. Im also thinking that the spline count in the hubs is really low and thus would most likely strip out if you were able to stick a launch. my orig thought was to use a 5L from a fox chassis, but that just seemed like it would be more work than i wanted and cared to do. i think that a decently displaced 4cyl thats somewhat modern would be perfect. i was personally thinking of going the KA24DE route. somewhat plentiful and common so parts are easy to come by and the motor itself is cheap. but as for the D16, give it a show. measure from the end of the trans to the crank pully and see how long that is. if we have the clearance then yah, you might just be able to do it.
