OwnerHi All, I have been a long time lurker here and enjoyed the amount of information and tone of this forum so thought I would set up a proper account and say hello.

I have been building a 1974 Civic 1200 K20 swap Civic for about 7 years total. I used to track race my Evo and then moved on to a Lotus Exige so this little project has been in the background for many of those years but all of the fabrication is complete so I am basically doing the REALLY FUN part now like running wires and fuel lines and brake lines…yay? . I kid but it was allot of fun getting to this point.

I used my racing knowledge and fabrication experience I gained from building my father a frame up restomod 1969 Chevy step side to try different things on this car and have changed it many times. However the motor is in, the suspension is in, the new firewall in front and firewall in back protecting the fuel cell is all done so hopefully she will be painted and complete by end of year. I’m sure am going to bug you guys for information as I put her together so thanks in advance.

Thanks Guys, I am almost ready for paint and finishing her this summer, I am working out interior and what is left that needs to be welded, filled, or braced before paint. Ill probably start and finish a project build in the appropriate section when I know what actually ends up where in the final product as I am still experimenting. Not sure if using RSX steering column or stock Civic, I am fabricating in a 2000 Civic console to cover the Ktuned 2007 Accord shifter plate etc e.g. lots to button up.

Regarding the D16, I don’t agree, for me specifically – I know k20’s so well from years of owning and pushing them to extremes so its very easy for me to work on those motors and my little brother is a very good Kpro tuner. I also had plenty of K20 parts laying around and wanted to fabricate allot in this build. What you don’t have to worry about in the D16 swap is the replacing of the components in the entire front end… and then the concern as to whether it will drive correctly after, if you calculated the g-force turning ratio correctly when design the angle of the xyphoid flux capacitor blah blah crash and die. I could have probably even had a B motor swap done by now, the inverse k20 just screws the whole pooch. And I really just have a shell now of the former car, I restore vintage amps (kenwood, pioneer, sansui) from the 70’s and although I upgrade a few things I really like keeping them true to original where sane. Your d16 swap will be able to retain so much of its original nature just with some more pep where as my ’74 k20 swap is more like a werewolf that you still recognize as the guy who turned into it, but is now a beast of a different nature and perhaps dangerous :flame . Its what I wanted but to be honest ill probably have another which is more natural eventually.

Updates on where the lil monster is, I got it back from paint and have been putting it back together, everything going slow as I am bascially customizing every little thing in full blown OCD mode. My trim was in bad shape so since the 72 JDM bumpers had to be painted (rust, dents, already painted 3 times etc) I decided to match up the rest of the trim with either satin black in the grill area or gloss like tailights, speaking of tailights I used this trick I developed years ago of using SEM candy apple red over the lenses and then clear coating to get rid of the faded hazy pink and bring out a deep blood red. I have been Powder Coating everything I can and painting what I have too, I have also sound deadened the entire car head to toe with multiple layers of different materials as another obsession of mine is Audio and this car is a soda can. I have an entire Image Dynamics/Hybrid Audio/Sundown Audio system waiting to go into it along with DEH-80PRS head. I am still waiting for my conversion harness from Hybrid Racing so until I get that am taking care of cosmetics and such – I have alot of loose ends that the kind members of the forum are helping me with obtaining to finish the interior and exterior – great guys on this forum! Any way here are the pix!

Size comparison, Civic will have almost as much HP and weigh about 500lbs less than its English brother, scary

Looks great! I like the small Mugen badge too :)

There was a guy in Florida who did this swap and was saying he was never able to get the steering right, in other words he was having an issue with the wheels not being able to turn enough to make the corners. Were you able to over come this? I recall he had some custom suspension set up which may have been the problem. His car has sold a few times since but oddly the only video of it in motion was slowly moving accross a parking lot. Not sure if he ever got it road worthy as he sold it off with the caveat of some more work was needed to smooth out the bugs. Nice to see someone else tackling it….now we need to see a s2000 rwd swap :)

My turn radius is very aggressive, I actually need to limit it with some kind of stop, I ended up using Toyota tercel front hubs to maintain my shock tower angles (meaning I didnt have to modify them) which allows for the stock pivot point to turn so I “should” be better off in that regard, But who knows lol, thats part of the fun, fabbing A-Arms is a 2 hour process anyway so even if it takes 10 iterations to dial it in I am ok with that. I fabbed up all those components myself so have the templates if i need to change anything. That mugen badge… its wayyyyy big I am still looking for one to cover the 2 holes where the 5 speed badge was and yet not be quite as large as that one, but thanks for twisting that knife, haha :D, Theres still alot of temporary going on with the car.
