Just did some googling so these are not my thoughts.
"If u use arp rod bolts you could go up to 8000-8500. If you have forged rods, pistons and a girdle you could go to what ever your cams make power to. The factory rod bolts are the weakest part of the block and could break shortly after factory rev limit for the block. Untuned i wouldnt go over the factory limit or give it all as it will have wrong fuelling and timing."
"Yeah a B16A or B16B would be a decent motor choice to do this. Honestly I would just make a motor make power at 8500-9100 rpm, as this has been proven to be safe and reliable.
But if you want to make an all out race motor, plan on spending a lot. All new valve train is needed; this includes new valves, springs, retainers, guides, seats and cams. Look into Wicked Industries cams, Rocket cams, or some crazy custom grind that will suit your setup. You will need a really good port and polish to bring in a buttload of air at those RPMs. Look into some sort of ITB or high flowing intake manifold set up. You are going to need a good fuel management system and ignition system to maintain what you are doing.
Then you will need a sleeved block, I do not care what anyone else says, honda open deck sleeves cannot take the abuse of 10,000rpms for very long. You will want a well worked over crank, that has been knife edged. Strong Rods and rod studs are key too, along with forged pistons. A light balanced bottom end is going to be key on a high reving application.
Then comes your transmission, either spend a lot of money on aftermarket gears, or go through transmissions every couple of times you race. That is just how it is."http://hondaswap.com/threads/how-do-u-m ... rpm.47442/
