No idea where to bring this up, but has anyone noticed an uncanny resemblance between the engines mentioned above and the EF series engines?
Let me know if I am crazy.
Thanks
It has the same bore as the EJ:
High Quality Chery 3 Cylinder 800cc UTV ATV Engine Manufacturer and Supplier | Acteco
Well, the pistons from one of those might work, if ever Daihatsu ones becme extinct. That would depend on piston pin diameter and location. For turbocharging applications, if those Cherys will lower compression to an optimum ratio, then that would be a builder’s way out of having to face either an absence or an exhaustion of quality Japanese stock. Other than that, any coincidental resemblance of one of their engines to ours would be the result of typical Chinese patent circumvention
That China engine is oversquare. Whereas, Daihatsus have a longer stroke, in relation to their bore. Because of the difference in power curves between both types, a differently-programmed engine management will also be required, as well as an adapter plate for fitting the China block onto Daihatsu’s bolt pattern.
If such an escqapade will prove thriftier than buying a good used Daihatsu engine, this is to be seen
I had a bit of a look last night and I agree with Butch the gearbox mount will need to be sorted. I was originally going to say that it looks like they used the Daihatsu cast for the blocks but Thought the heads were slightly different and they resemblemore of an ej engine or and efdet.
I do like the bore size being that of the ej the shorter stroke would be good for reving too so I feel it would be good mix of torque and revability.
I think cherry also did a similar engine to the cb23/24. No one ever got one over here in Aus to actually play with them.
With everything there I would be very curious to see the engine specs and especially the pistons and rods for the engine and if they are the same and just using the cherry pistons can drop the CR of the ejde/ejve to give a more flexible option for boost.
The price currently for Australia does not justify getting an engine as a 2nd hand one can be had much cheaper.
I also looked at the 1.0L engine they have but could not find much about it really.
It looks like some of these Chery engines are missing 2 bosses on the transmission side and when they are included, they are not drilled (weld in and drill?). But outside of that and some valve cover weirdness, this looks incredibly faithful to the EJ. They copied everything down to the webbing.
Even if these were practically junk in comparison to their Japanese counterparts, and ran like doo doo without reprogramming the ECU, if they would “drop in”, I’m sold.
I reckon they would work and if you got an aftermarket ecu and trigger wheel then I think t would be well worth it. I would still love to see the piston’s and measurements for them.
I just had a look for pistons and they are pretty cheap on Ali Express and they have oversize also. What I cant find it the gudgeon pin height to the top of the piston and diameter of the gudgeon pin etc for the rods.
The same pistons are used for the 1100cc engine also (SQR472)
Something else that maybe handy. I found a sort of engine manual. missing some specs for reference bt give the tollerences.
[quote=“shanescott, post:7, topic:6919”]…some of these Chery engines are missing 2 bosses on the transmission side…[/quote]That the second and third image you posted shows either or, why not get the one which has undrilled bosses? You could then bolt on your Daihatsu bellhousing, thereafter drilling and tapping both virgin bosses, using (I forgot what you call this sort of punch) a punch which will self center. They are available in all usefull diameters. We used to use solid ones. The following is principally identical in function, with the exception that it’s spring loaded:
it’s not clear, as to if your China engine will be included with those dowel(?) sleeves used for precision aligning your engine to its assigned-to bellhousing. The three pins mandatory for bolt-up should suffice, so that you should not need worry about adding these to your block. Drilling for these will require even more meticulous accuracy than for the bolts themselves

Here’s a source for a set:
If the site’s image is accurate, directly representing the proper pistons for this engine, it would be possible to measure the dimensions desired, through enlarging an image and then measuring it on your screen. Using the piston’s diameter as a reference point, you could then compare the piston diameter’s distance to Gudgeon pin diameter and distance to piston top
I would not trust a website’s images as accurate therefore I would rely more on written data and measurements. I am excited of the potential of these developments in research.
Furthermore during research I remembered that this model of cherry was sued from GM and maybe Daewoo as they ripped off the Daewoo Matiz or Chevorlet Matiz also. Hence why the 800cc also the gearbox’s also look similar to the matiz and the the L2,L5,L6 style of dai gearbox’s.
The matiz bore and stroke os 68.5 pistons and 72mm stroke. So the Chery still seems more of a dai/daewoo/suzuki mashup.
Either way when I get a place I can play with my dais again I will definitely be looking into this. The pistons could even be used (another possibility) for a k3 engine to drop more compression for boost also.

…the Chery still seems more of a dai/daewoo/suzuki mashup.[/quote]Being the owner of a first generation Suzuki Wagon R Wide, the gearbox crossover is interesting. I read somewhere that one of those Daewoos uses a gearbox which is more durable than mine and would fit plug & play, maybe with the exceptions of clutch cable and shift mechanism? If so, it would be better off with a hydraulic-operated clutch, on these. Cable shifters are remarkably accurate on Suzukis. Mine is rod-shifted which was in need of updating, that is, if I can’t find an automatic transmission for converting over
the matz did have issues with the cable shift from memory. 3rd gear mainly if I remember correctly. However when I had one I never had that issue.
I would’ve lmao’d if they had copied the manual too!
Just copying everything lol
0 effs given on their part hahaha
yeh they got in heaps of shit for it from memory and yeh pretty much 0 effs at the time but hey china lol
