Update 1: initial engine build and first test fit (Dec. '13)

Update 2: complete remaining 10% on the engine (March '14)

Update 3: second test fit. finalize fabrication items and wiring routing. [July '14]

Update 4: completed driver's side mount bracket (first revision), marked frame rail for A/C compressor clearance, made final cuts to oil pan flange to clear the inner CV joint and found that accessories bracket system version 3 will be needed for final install. (Dec. '14)

Update 5: Chassis ('00 EJ6) has retired from daily driving duty! Second version of driver's side mount complete. version 3 of accessory drive complete, clearance cut to frame rail done. (May '20)

what is this...

-F23A1 block, crank, rods (ported oil pump, balance shafts eliminated, H23 ARP head studs)
-K20A3 pistons and rings (stock, rotated 180°)
-F22A4 head (reman-ed, HD springs and Ti retainers, reground cam; Delta 272)
-H23 intake manifold (IAB delete, mild porting, BWR pro-cast 68mm TB)
-K23A1 Injectors (RDX, Rosko Racing fuel rail) [thanks PirateMcFred!]
-D16Y7 engine harness (heavily mod-ed to fit, partially "tucked")
-H23 exhaust manifold (downpipe modified to fit)
-P06 P75 ECU w/ S300
-F2D adapter kit (Bisimoto/Exospeed)
-S20 5spd

other stuff...

-mild suspension upgrades

you want to hear the story I guess.

I was given a low-mileage JDM F23[[i]A1] for free. I had no plans for it but I knew I preferred the chassis dynamics of my EJ6 to my CG3 (which already had this same engine...) As it turned out, some fellow in California had a kit for adapting this engine to the transmission in my Civic. Oh and BTW his record-breaking drag car uses an F22A in part because the head flows so well. I guess I should use the same. So what are guys doing with the F22A in street cars for affordable power? H23 manifolds fit and I can get a good (but maybe not great) cam regrind for $100?! I'll need more compression and more fuel to make the best of those changes. Believe it or not some of the K-series parts will work off the shelf and do just that. So that's how it started.

I also was committed to it remaining a street driven, reasonably practical mode of transportation. So A/C would be a requirement here in the southeast. Other expectations that developed as I researched similar builds. In stock form, the F23 would nearly double the torque of the D16 it was replacing without having to rev nearly as high. But I do enjoy being able to wind it out from time to time. so good low torque and decent top end would hit the spot. It seems that 200hp/180tq are pretty doable. With the chassis side pretty well sorted, those numbers should make for a nice back-roads car.

But, will it ever be finished...?

 

Lookin good so far.

That f23 girdle is crazy.

 

Can't wait to see this thing come together. I forgot, I also have a chip that has been tuned for a F22A6 with I/H/E and a 272 cam, so it should at least be a good basemap to begin with.

This car is going to be a torque beast.

awesome! keep up posted!

 

it's gonna be beastly!


btw this is phil

 

I really wanna see this done... I have seen threads amost exactly like this but with a stock f23.. it was pretty impressive for being stock.. The guy said is was really torquey and beat b16...

 

In for the info and build....I've always wondered about the f2d in a civic. Good luck!

Good job on the BS install. I got the kit and had the same problem on the f23a5.. I just went to lowes and got the steel plugs and drilled and tapped the whole myself.. I didn't feel like waiting on shipping and trying to contact Kazien Speed.. but now Guess i should have it would have been easier for me... People say that the h23 balance shaft kit would have been a direct fit .. I assume you got the h22 kit.. its the same one I got because there where no other options on the website for the h23 kit.. if i remember correctly.

Looking good! May i ask why you f2d kit instead of just the straight f22 swap with a h22 tranny?

 

well there were a few reasons. It seemed sensible to use the transmission that I already had in the car if I could as opposed to finding another one that I knew was larger and a little heavier. I would also need to get mounts for the full F-series swap. with F2D I reuse all but the driver's side engine mount.

Also, I really don't like the cable shifter on the H and F-series transmissions. it feels sloppy to me, even when it's not worn out.

 

I didnt know the f22 bolted right up to stock d series mounts besides the drivers side? What about front and rear mounts?

nice.

Looking good, I like that girdle a lot!

 

Nice build not to many f2d guys out there.

F23A FTW

Nice work... keep us updated on the progress.
