In particular, I want to see what the main bearing carrier looks like. As I understand it, the F20C uses an aluminum "ladder type" main bearing carrier that signifigantly increases bottom end rigidity. I recently bought the "Honda S2000" book from www.motorbooks.com but there weren't very many pics of the motor. Being a genuine motorhead I am really impressed/thrilled with the F20C. Real pride of ownership. The F20C has some really incredible features such as the carbon-ceramic cylinder liners, roller-bearing cam followers, the above mentioned bearing support and so much more. If anyone has a link for some pics of the F20C (disassembled) I would greatly appreciate it if you could pass it along to me. Thanks in advance...

Best regards,
Matt

 

when I pull mine appart in the next few days, I will get you some pics.

here's what it looks like with all the parts together

The black spots on the air intake are water, i just hosed it off and then took that pic.

 

Ladder? Did somebody say ladder?



More pics of our engine torn apart during the our bottom-end replacement:

First off, thanks for posting the pics. If it's not too much trouble Mark, I'd still like to see the pics of your motor when it is apart. Why is your motor coming apart? Doing anything interesting or is that G-11 classified information? What happened to your piston Jason? Did it seize up? Sure looks rough. I read somewhere on the board that someone cracked a piston. I also noticed that the combustion chamber looked awfully dirty (Carbonized). How many miles are on the motor? I've never taken apart a car motor, but I did tear down a motorcycle engine (91 GSX-R1100, 1216 cc air/oil cooled motor) and the piston/combustion chambers were much cleaner. Granted, it was a high compression motor (12.5 to 1 static) and I always ran a pump/race fuel mix so maybe that's why there was such a difference. By the way, I'm not sure what part was the main bearing carrier. I'm assuming it's the bottom of the block that is holding the main bearing caps, but I was under the impression it was a bolt-on piece and it looks more like part of the block to me. Any ideas? Anyway, thanks again for the replies and the pics...


Best regards,
Matt

 

The HyperRev magazine specializing in the S2000 has some very good pics of the entire engine disassembled. I don't have a scanner, but perhaps someone else that does can post these pictures, or you could buy one (though expensive, about $35).

Wow! It turns out we drive a real work of art....

 

Matt...please check your e.mail.

 

#4 Cylinder failure... I think there have been about 10-12 failures reported on the board here. They all just start with a tapping noise and end in a short block replacement. Mileages range from 700 to 6000 I think. Ours happened at 2200. Our best estimate is that it has something to do with a lack of oiling in #4 or exessive heat causing the piston to expand and score the walls. Ours still ran in the condition you saw, it's just that the skirt had collapsed and was rattling around in there, making quite a racket.

This one annoys me... It's because of the stupid oxygenated alcohol infested gas they force us to use here in Chicago. The fuel, which is supposed to burn cleaner, leaves way more deposits after combustion. That picture is after a mere 2200 miles. It annoys me just looking at it. I like nice, clean combustion chambers.

I'm not 100% sure, but I only think it looks like part of the block. I think it fits pretty snug in the bottom of the block and therefore looks like one piece. Instead of individual bearing caps, there is one large ladder shaped bearing cap assembly... pictures don't do it justice!

 

The ladder bolts to the bottom of the block. What you need to see is the Helm manual or a scan of those pages (sorry, my scanner is dead).
