    Catching up here. The whole timing issue has been a big setback, time wise. It almost got delayed another week because I thought I lost that spoon-shaped bracket and its spring for the balance shaft pulley tension. Got lucky, though.


    Finally got around to cutting up the PLM header so it doesn't hang so low. Didn't want to get too close to the pan, though; I'm not sure how much that heat will affect the oil. The little loops for the spring bolts have since been cut and shaved smooth as well in preparation for the header to be welded up.








    Here I'm unpacking the boxes of parts I've had in storage, seeing what I have and what I still need. Power steering line into the top of the pump is a biggie...




    Back to the undoing of the H23 manual tensioner. Aside from the KS Tuned parts, I ordered everything from Honda. Even small parts I already had, I got them new just because I wanted them mint! The connector on a coolant temp sensor had also broken in storage, so it was replaced.






    And of course, being a company that sells balance shaft deletes, KS Tuned designed their walk blocker without catering to those of us who want to keep ours, so I had to make up a spacer. Luckily I had a washer of the right thickness and a solid width laying around, which I enlarged the center hole to fit snug over the pulley's locating bolt.










    I also finally got around to taking care of the K-Tuned oil sensor adapter, sandwiching a washer between the adapter and the factory receiver so the K-Tuned oil ring had something to seat against:




    I may have shaved this washer a bit too small, but it looks like it'll do the job (service manual was back out because I took the cams back out to double-check that everything in the head was torqued to spec):




    Sensor adapter mounted under the S2000 oil filter. Anyone know what that 10mm bolt is for? It's been so long since I took this apart.




    As I mentioned earlier, the adjustment bolts on the Skunk2 cam gears was rubbing on these indentations in the upper timing cover. I cut them out hoping I could simply move them further out and plastic weld them back in place to try and make it look like the cover was never modified to begin with, but it still wasn't enough. I had to shave more plastic away from the gears, so until I figure something out to seal away the timing area, the gears are going to be slightly exposed...

    I'm pretty sure it was the H23 tensioner system's over-tightening of the belt that was doing it. We'll see in a few days when I can get out to the engine and put the H22 parts on. Aside from the KS Tuned parts, I got everything else new from Honda. *ED. - oh, and KS Tuned says that the metal bushing that the manual tensioner pulley pivots on (#24 here) wears out over time and allows the pulley to sag, which is a common contributor to belt walk.

    Fleetw00d, I PM'd you, thanks!

    I've got a half shaft if you want it.

    I use my power folding mirrors every time I drive the car Say, you ever figure out the belt walk issue?

    Finally! Been waiting for these parts before posting my progress here. I'll have the engine assembly completed this weekend short of small things like vacuum hoses. Interestingly, the tensioner pulley with walk blocker installed was cheaper from KS Tuned than getting the pulley by itself from Majestic. 3D-printed cam gear holder is a new freebee they throw in when you buy their more expensive parts; nice detail in design for such a simple piece.




    Still need to fund:
    - Junkyard transmission
    - Fluids
    - ECU w/Hondata and basemap to confirm engine runs as it should at home
    - ST rear sway bar so the exhaust can be routed to allow for it.
    - Get the full exhaust system welded
    - Dyno tune
    - Register the car


    Power folding mirrors are also installed, but still need to be paint-matched. The funny part is I'll probably never use them for fear of the motors dying and not being able to replace them. DIY for the external relay system coming soon.

    I have it, I just need to cut out the little half-circles and probably plastic weld them flush with the rest of the cover, just so they don't stick inward and hit the cam gear bolts.

    Currently waiting for all the parts to ship from KSTuned and Majestic to convert back to the H22 timing tension system (some parts need to be ordered by both parties before they can ship them to me), and in the meantime I'm finishing up the header fitment and intake manifold polishing. I'll get pics up when those are done.

    But I was cleaning the plastic timing covers and discovered that the upper piece doesn't clear the adjustment bolts on the cam pulleys. I have that valve cover that leaves the gears exposed for the dyno and for going to shows, but I definitely don't want dirt getting in there otherwise, so that'll need some customizing...

    Thx for the props on your build page on the cb9R loving the detail of work on the car and engine bay. Any updates

    With my luck, it'll blow on the dyno.

    Dang thatís nice. I hope you get years of use out of that engine.

    Well, I discovered that the bolt that holds the tensioner pulleys was only hand-tight. My bad! Still changing the tensioner system. Looking at the parts prices at Majestic is slightly depressing, though.

    More external assembly, and it's looking like an engine again. On the distributor, the part that plugs into the camshaft, it's designed to only go on one way, right? So we don't accidentally set it 180* off? I was worried that one of the tabs was bent at first.


    I suppose getting a fancy cam seal is kind of pointless on the H22.








    Every single gasket, seal, and o-ring in this engine is brand new, so I'm feeling pretty good about it!

    Skunk2 sent me a different how-to guide on degreeing. Much easier. No math. It confirmed that I did get the intake cam correct using MotoIQ's guide, but maybe they just didn't do a good enough job of explaining how the formula translates to the exhaust cam, I don't know. But my cams are now degreed in! Intake needed +0.5 degrees, exhaust needed +1 degree. Now I think all I have left to complete assembly is to figure out the timing tensioner situation, converting back to stock H22 hoping it doesn't max out the tension, and then get the KSTuned parts for reliability.

    Kaizen Speed makes an piece to add that prevents belt walk also. Usually it's because the belt is too tight. I used the OEM H22 tensioner and drilled it out and put a carriage bolt into it, creating my own manual style tensioner.

    Also I've read about weird center line issues with cams before as well. But they were usually J series engines with the single cam.

    wow, that's too nice to put in a car now. Better use it as a table

    I had the belt walk off thing when doing my timing too. It was that the one of the pulleys was not on proper, believe it was the tensioner one as it has the two parts to it in a weird way. If the belt is way too tight this problem may arise too (assuming you forced it on there). But something is not level and causing the belt to walk. Keep looking!
