Message: <blockquote data-quote="shiroitenshi" data-source="post: 2402040" data-attributes="member: 27518">Well.. you can search up the previous threads.. it's not something that's unachievable, as it was not done once, but twice... the prev threads were inclusive of dyno charts.. one was a stock block with milled head sans accessories, got 206whp on dyno dynamics (at 9K, if I'm not mistaken). This was by a track racer, his nick is chris2000 on zth.The other one was on a Dastek dyno, which some may say reads high, but considering the fact that the injectors were severely undersized for the application, managed to get 200whp at 9K... I believe 215 is achievable due to the capacity and compression, but currently the owner is planning to switch to another management system (he believes that it's the management issue inclusive of the injector sizes.) I tend to agree.. with more agressive setups, the closed loop function of the stock ECU is a serious damper on performance, and it's risky as well, because it leans out fuelling at part throttle (which incidentally is affected by more variables than I can remember), and coupled with too high ignition advance.. Kablooie!But civic K20A type R making 150whp? Err.. I think there's a few posts here about K20ARs making somewhere in the region of 200++whp here in stock form... and I've personally seen a dyno chart of one to boot at 230 whp, with fat torque at low end that makes my B16A look like an anorexic.... 150whp peak? Heck, my B16A makes more than that at the wheels, even if I factor in dyno overeading by 10hp!  As for the Toda strokers... well.. it costs quite a bomb, that I know, but I'm not sure of the specifications and unless it is a big stroke combo.. well.. I'm not sure it's worth the money.. the stock R crank, I believe has been tested to withstand high hp, and it's probably not the weak link in the engine.. unlike the pistons/rod.Anyway.. 9K+ on a B18C = extreme sleeve wear.. unless if it's resleeved with harder liners.. don't expect the engine to last long.Then again.. when you resleeve, why stick with only 81mm bore? Heh.Oh, Toda forged pistons have very high comp.. esp their 82mm bore units which don't seem to have a mild dome, although the chart that came with the piston seems to mention a version with a smaller displacement dome for less compression. But never seen that one, and don't know if it's even available on the market or not.If lastability.. stock R 1.8 stuff.. probably with Toda As or something... and rev-limit will probably be your best friend in retaining that lastability.. 9K is good for weekend rides, but if a daily driven car.. well.. you can ease off the pedal or drive frugally, but who does, when they have 9K rpm on tap? (^_^)And the tuning is probably one thing you will have to consider to get that last bit of power out of the stock unit.. but as one guy already proven here... it can be done, and on a slightly modified stock block with cams no less.It is.. unless you tune it.. running it with the stock ECU once made me think that it is slow. It takes like ages for it to climb to the VTEC point. Again.. stock ECU.. tuning would probably sort that out.. but in stock form.. yeah.. the B16B is slow. But modded wise.. ask one guy here who probably can lay the claim to having one of the fastest B16B's around. I'm sure he will drop by this thread soon.. :P</blockquote>
