yea k series has more parts available mainly cause its still newer and latest engine Honda use(excluding j series and the r series). just like you'll have much easier time finding parts for a 2004 model cars then you would for mid 90s model car. k has not supersede h at all yet, stock k swap civic already got beaten by a stock h2b civic before.Bismoto and ks tuned both have shown its potential and proven things otherwise. ks tuned owns the fastest h2b to date and has done 8.50 and better in quarter mile. A guy named cedric aka fast guy racing finally the first SFWD ek coupe with the k swap to brake into the 8 second bracket and that's high 8. H series did have as much aftermarket support not as much nowadays. but theres been as much support in the past.
K has more parts available because it's newer?....But a B series is older and has far more available for it. It's a simple fact that H series has never had the same kind of aftermarket support because the H engine has more short comings than the K or B series.
a stock "K20" was beaten by a H2B, lol, so not even a straight stock H series setup and it was against a lower displacement K.
There aren't as many K's with the record breaking times currently, because of the main thing that has been mentioned over and over here, cost. For something like SFWD, it takes quite a bit more money and trial and error to get a K into the same time frames. When you consider the amount of time it took a K to get close to the B series record times without forgetting how long and how much support and how much trial and error has been done for a B, the K is still impressive.
a clear fact of that is....the B series and the H series are having to incorporate K series technology to compete on a higher level, meanwhile the K is still being learned and taken to new heights.
nobody here has said any of the older engines aren't worth anything to build, but we all, excpet you, have said that they are all dated outside of a K series.
