timot_one's CM5 K24 Build

Since I'm sure that very few people know me here, I figure I'll show you what I'm working on right now. I have an '03 Accord sedan that has been my daily driver for the last 8 years. I started off slow with stereo stuff and exterior upgrades and got into the motor shortly after that. I'll spare you the boring details between now and then and bring you up to date as to why nobody has really ever seen my car since I moved to OH last year. When I was driving home from VA back in May, 3 teeth broke off 6th gear on my countershaft. While the motor was out and the tranny was being fixed, I decided to upgrade my valvetrain. I got everything back together and ready to get retuned for the new upgrades. The day after I got the motor running, a valve dropped and destruction ensued. Time for me to build the motor. I'm just waiting for my block to come back from the machine shop so I can clay it to check for clearance and then assemble everything. It should be back on the road by the spring.

Here's the car.


Here was my set up before I destroyed the tranny and motor.




Here's the damage:
You can see the valve stem broke because the tip of the stem and keepers were still in the retainer.



I found pieces of my valve and valve seat in my intake manifold.


This is what I found when I pulled the head off.




Here's the block almost ready to go to the machine shop.

Here's my new head.


I'll try to keep this thread updated with progress after I get my block back.

Damn son! how much boost were you running? either way looks good. you really don't see many people work with this chassis. glad to see the diversity in builds lately. good luck and make sure to keep us posted.

I definately agree, i love fast sedans ( and a supercharger whine)

When I had a turbo d16 one of the valves broke and it stuck right in the piston.

Before the upgrades, it was at 10 psi. I literally had 10 miles on the motor after upgrading the valvetrain with new valve springs, retainers and cams. I was merging on 75 at about 1/2 throttle when this happened. I keep thinking I made a mistake when I upgraded the valvetrain, but a good friend of mine that does a lot of J Series builds keeps saying that it was just one of those freak things.

Thanks man. Believe it or not, but there are a few Accord sedan's running around making decent power. I know I was the first person to SC a K Series Accord, but there are others making good power. A buddy of mine out in Columbus has the same year sedan as mine and he boosted the stock K24A4 and is making 350 whp / 400 tq. I foolishly drove it once when it was wet out and the tires kept breaking loose in 3rd gear doing freeway pulls. Another buddy of mine from Oregon build a 560 whp boosted Accord sedan that's the scariest car I've ridden in so far. I guess I just know more about these builds because I've been in the 7th Gen Accord community for a long time.

Really cool. Are you using a shop in Dayton for the machining? If so, which one?

Always cool to see people building something different.

I took the block to ERL Performance to get it sleeved and assembled. I took the head to Piqua Automotive to get the valve guides replaced, and will be bringing it back to them after the port work has been done.

ERL does good stuff. My Sleeves were done by them. Post up pictures once you start assembling the motor again!

I know ERL has a great reputation in the K Series world and a great reputation for customer service. They were cool enough to give me a quick tour of the shop when I brought my block down to them. I was only going to have them sleeve the block, but then realized that it would be better to have them assemble it too.

I'm hoping I can get my friend who's a photographer to come and take pictures of the assembly. As soon as I get the block back, I'm going to clay it before final assembly. Even though CP claims my pistons are 50º VTC safe, I want to be 100% sure. Since the block is going to be decked and the head is going to be milled, I want to make sure that I won't have any clearance issues. The good news is that if I need to gain additional clearance, Cometic makes head gaskets from .030" (stock thickness) up to .051". Hopefully, I won't have to limit the VTC advance.

currently building a 12:1 k34 bottom end for my teg

Awesome. I have a ton of random k series parts. Let me know if there's anything you may need to help with your build.
