I know the guy that Barry referred to fairly well, and was recently in contact with him... He's making a custom crank, boring .100 over, and using the honda rods and custom pistons as well as a ton of other cool shtuff... He projects it to be right around 2.9 liters when complete... He's built several cars that have been in magazines, and run 8, 9, 10, 11 second times... VERY knowledged guy... He's the one that started my thirst of info about the k-motors...
As to the inital question for this thread...
It's no secret... it's the same-ol' shtuff, different car... you'd toughen the bottom end of our motor the same way you would any other motor... our engines are just as run-of-the-mill as the ages-old pushrod motors you'll find in american cars... that is, in the sense of suck-squish-bang-blow, spark plus air plus fuel equals kaboom!... everything else stems from that... how do you get more suck? add volume, open up breathing ways, time the suck better, etc... more squish? push further, change timing, etc... more bang? optimize your timing, fuel atomization, intake air charge, etc.. more blow? optimize timing, reshape your pistons, optimize your exhaust, etc...(disclaimer; those are not all-inclusive answers to more more more... they're just a few of the millions of KNOWN examples) when you get to the point in the chain reaction that rods start bending, how do you fix it? stronger rods... not enough fuel? healthier fuel system! bending the crank? stronger crank! if it breaks, then strengthen or redesign it! and furthermore, this stuff is more art than science, if you ask me...but there are more physicists building motors than artists, i'm sure, so don't ask me..

there are thousands of books worth of mathematics and physics behind the reasoning for why these motors were built the way they are, but if you want to get to the conclusions that the fast guys get to without taking the long way through all that education, then just dumb down a bit and use my cheat sheet

better yet, make your own... how do you get more air in the motor? I'd tell you to alter valve timing or remove some air restrictions, or something like that, but look at it from your own perspective and you may stumble onto the next great idea... VRIS wasnt on the first mustangs... spit your ideas out there and if it's something great, someone will help you show that it's great... if it's wrong, hopefully, someone will show you why... No secrets in this game though... he's just doing what's been done for years, just on a new platform. Who knows, maybe he'll stumble on a discovery that will improve the holy hell out of the k-motor...

.............. and yes, searching the archives is a good idea..
