Extreme Engine Tech: Building the Ultimate K24 Part 3- The Finished Goods!

,

Howard uses the “special tool” to install the oil filter stud in its new location.
Now the oil filter can be installed in the new position.  Pretty easy so far.
This is the oil filter block off plate that used to be where the oil filter is now.  We ran into a small issue on ours, it was slightly hitting the bed plate and would not drop into place.
We had to remove a small amount of material on the edge of the block off plate on an apex grinder.
After the material was removed we were able to install the block off plate and bolt it down.
Here we go, a new, cleaner solution to removing the balance shafts, lots of room for our awesome Moroso oil pan and a nice factory solution for dealing with the change of oil passages in the new pump.

  1. On part 3 page 5 timing chain is fitted wrong. Timing marks are not correctly aligned and timing is not set properly . Little dots on cam gears should be between gold chain rings. Dashes on intake and exhaust cam gear should point to each other!

    1. We were just doing a dummy fit up to check the tensioner so of course, we didn’t assemble the engine that way. Good catch though!

  2. I appreciate the time, effort and great photos in this article guys, but there are some serious holes in the story here that need to be addressed. RBB valve cover to R40 timing cover does not seal. PRB non balance shafted oil pump conversion requires blocking the old feed port on the block beneath the oilpan. Youve used the incorrect chain tensioner for the r40 block as the old steel bodied tensioners have a slightly different oil port location. Moroso pan doesnt have provisions for the lower torque mount. Although you used aftermarket pistons maybe some measurements on a stock piston compression height and how that clears with these heads. Maybe spotlighting some of these details maybe help to better guide your reader base in tackling some of the hurtles of the R40 4-port conversion. Either way, great content and thanks for your contribution to our industry.

    1. Its been a long time since we wrote the article but I am pretty sure we covered how to do that stuff in the other parts of the series. I know we did the balance shaft and cover stuff. Pretty sure we did the tensioner in other parts. I remember getting the new tensioner.

      1. If there is a revised article beyond this “part 3” that covers these issues, I wasnt able to find it. Is it under this engine build article or something different?

        1. I think there was up to a part 5. You know what, I think I covered this stuff more in our NA build. I am getting things confused. It’s been years!

  3. Great article, Im wondering what engine wiring harness would be used for this build to go back in a 2012 civic si coupe?
    TIA
    Steve
