Lets Talk Honda Engines- Discussion Thread

[foamypirate]

Scott, if you don't mind, could you go into details on the architectural differences/improvements from the H to the K? I'm curious to hear more info on it, and all I can seem to find online is "it's a DOHC i-vtec with blah blah stroke and bore and blah blah compression," no detailed information. Then again, my search skills are a little rusty.

I'd also like to hear some more information on this, and the head design. It seems to have this great flowing head, but nobody ever goes in depth on the subject.

That's awesome man. The fact that this guy put it in an EF makes it even better. That thing must SCREAM! Plus, less than 2k for the build!

again it actually defeats the whole thread
hybrids dont count

if not, h would have been ownd by high comp k20/24

"The result: 248.6 whp and 181.2 lb-ft of torque, as measured and tuned by the Latrobe, Pa. based HybriDynamics crew."

absolutely amazing IMO. i would love too build this engine and put it in my cb just for the experience and also the performance aspect.

"Chris has had his EF out to the strip a few times since completing its build. It's gone low 12's with a full interior and street tires, and Chris expects to be deep into the 11's after a head port, tuning, and possible over-bore."

This is true, considering this thread is dedicated to HONDA engines, as in, the way they came in production.

Keepin' it on topic.

oops. still impressive though. IMO.

Yes, yes, I am actually glad you shared that article. Very nice.

didnt know we werent talking about hybrids....techinically its a honda engine! just not manufactured by honda. but still a cheap alternitive to making usuable numbers without dropping 5k+ on a kswap.

hybrids will always be cheaper in price

j series are coming into play now

so expect in a few years the same article

instead of spending money on a j
make a k hybrid for half the price

battle has been going on for years, and will not end

If we all had Bisi brains and resources for precision and accuracy. We would all build high powered reliable honda engines. Im loving where honda is going with there new designs. Every honda fans are going to do something different to it either for a dd or an all out track star.

This is some old technology but wonderful in many ways as it puts out enough power and does really good mpg. Great read for honda engine fanatics. Enjoy.http://asia.vtec.net/article/d15b/

The H and the K are both good motors, as far as the ease of extracting the horsepower the K wins that argument hands down. I like the Einstein analogy, that was a great way to prove the point! They both however do come with some issues, the H has the famous sleeve problems and of course the less than fun gear ratios. The K has oil cavatation problems above 7000 RPM and the transmissions have problems with "pop out" at full thottle. All of these problems can be fixed with aftermarket solutions and of course the K series is the king of the after market support right now. So it is easy to say that the K is the winner in that argument.

My favorite factory motor is actually a tie between the B16B and the K24A2. I dont think that there is a better motor from factory that is ready for as much abuse as the B16B is. 185hp, great rod ratio, can easily be swapped into any civic or integra, and is ready for a full day of abuse from factory. I vaguely remember a race team that just bought factory B16B's to use in the 25 hours of Thunderhill a number of years ago. And the K24A2 is a big torquey motor that has the benefits of the K20 but with the grunt of a 2.4L. I remember a Honda Tuning issue that did an "unleashing the HP" type of write up on the TSX and with relative ease they got 186WTQ and something like 220WHP with just a header, intake, tuning, and VTC adjustment.

That's just my two cents.

H seems less complicated than the k series....imo h series is the shit...new technology can be very dumb

you dont need bisi's brain, i think there's some pretty damn smart people out there, that most of their ideas and thoughts get smashed by the lack of money

bull*&^^, nowadays if you can build a K you can make some money, is just a motor, the way, you check oil clearences are the same, they way you gap the rings are also the same, the way the pistons go in are still the same, everything else is assembly
