79-81 vs 82-83 ek1751
Civic1200 Discussion Board: : 79-81 vs 82-83 ek1751
Just thought I would add my few cents worth to this thread. I have a 82-83 canadian 1600 with a 79 civic 1200 5 speed. Machining had to be done to use the 79 flywheel with the 82-83 accord. Same as if it were a pre 82 1600 I believe. Shane
charles,
thanks for the info, i think i found an 81 EK for sale. but i was thinking about passing it up for a newer motor. i think i will go back and look at the older motor again. thanks again
You may not get the 82+ engine to mate with the earlier gearbox.
I have this setup in the '77 that's for sale, and I had to use the tranny from the donor car because the flywheel had a larger dia. and it would not clear the bellhousing.
Swapping the flywheel was not a simple bolt on affair either. The later crank/flywheel uses larger bolts (12mm vs. 10mm) and a wider bolt pattern.
There's also a shifter linkage issue with the later tranny, which I solved by welding the appropriate ends together to form a custom shift rod.
Unless there's a simple way I don't know about, try to stick with the '81 and down engine.
You will pass right through Hope...Quesnel is about 5 hours north of Hope. The 1200 head will not work on your CVCC motor. However, here in Canada we got non CVCC 1500's. I would imagine the same goes for the EK and the EL in that you could likely bolt up a non CVCC head to your block. Not sure what difference it woould make though.

thanks for the info. i have thought about the 1200, but i have not seen any in the states. sounds like the EK is the smart money. eather of you know if i could get a non-cvcc head for the 1500? like using the 1200 non-cvcc head or some thing like that? how far from quisnel is hope? i may be goin up there in the spring.
Rob,
I think it was Ted, Rick and Errol.
I thought we got the EK in the 82-83 Preludes? I have thought about the EK myself but as we Canadians already have the non CVCC head I don't know if we would gain much more power other than the little bit from the extra 150 cc's.
Personally Rob I would go with the EK over the 1500. They are both cast iron blocks so weight is not an issue. The EK would easily swap into the bay and as its already a CVCC you would not have to modify your torque rod, shifter linkage, hoses or fuel pump. NO Welding 
. Plus, down the road you could swap the CVCC head for the Canadian head. What about the 1200? Lighter, easier to find hop up parts (well a little bit) and you could always build a stroker. I know - decisions, decisions!
Kurt
Well some people may disagree, but I say ditch the 1500, now we didn't get the EK up here, but we did get the EL (1600) which me and Kurt both have in our cars, I think the amount of work to install it versus the power increase makes it well worth it. Me personally, I would like to try building up an EK and putting the EL head onto it, I know its been done but I'm not sure who it was?
kurt or kyle,
my civic is a 1500cvcc, and i want to tune it up a bit. what is more bang for my buck, build an ek1751 or just work on my 1500? any advice. my best friend is a macanic but i dont have a shop to do a lot of cutting welding.
Thats right-6000 people! Someone else just moved to town with 2 first gens. One looks like a parts car but the other one has the deluxe gauges and Honda leather wrapped shift knob...I havn't knocked on the door yet!
Its a little hick town just over an hour out of Vancouver, right Kurt? =)
where is Hope BC? i'm not sure where that is.
I'm from Hope. I know Pick a Part in Chilliwack has quite a few EL's although I could not say for sure when the last time they were run. I think Shane had some EL's for sale not sure about EK's though.
Kurt
i'm in portland OR, there are a few EK's around but they are in bad shape i would be starting with a blank block. i wanted to start with some thing that as run in the last few years, ya know. where in BC are you from my little brother lives in westminster, and i have property in quisnel.
Where you located, the wreckers here in BC are full of the El's
thanks for the info. i'm looking at getting a motor soon, and most of them at 82-83 the 79's are tough to come by. i can get the 79 but it is a re-man and i want to do the work my self so i can add all the goodies(blue & balance, EL heads, carbs, electronic ignition, cam, crank, headers...)
do you have any good recorces for getting motors? i did the on-line serch, lots of places have longblocks for 600+-
thanks again for the info
The actual swap itself is the same, its the differences with the heads
sorry to bring back an old subject, but i read a lot of discusions on this site, but never saw if ther was a difrence in 79-81 EK1751 swap and the 82-83 swap into a 78 1500 cvcc.
