j's car pulls like a beast on the touge

 

All those mods, you could make 300hp crank horsepower with less. JDM is not all its cracked up to be.

 

The difference is that you can run it reliably on the track for a season without blowing the motor -- they could also make 300 crank hp for less than that, but they did it the right way so that they could run a reliable track car. That's the big deal w/ the good JDM companies -- they actually build 300 hp engines to race on tracks, not to post on websites and magazine covers

 

Yeah the j's car is very aggressive. Probably the reason why their engine blew.

 

Who said anything about making it not reliable? You can make 300hp on a stock bottom end NA with no sacrifices in reliability. If anything a build like that to get to 300hp just shows me how little these guys actually understand increasing engine efficiency. It is not about throwing the whole "JDM TYTTE YO" catalog at the engine. It's about minimizing the weakness' and maximizing the strengths of the power plant.

 

First of all, their entire bottom end is made by Honda to their specs, so it's not that much different from an OEM bottom end. They basically just bumped the compression and got some stronger rods. So I don't see how you can say that balancing and blueprinting the engine is detrimental at all ... it just seems ridiculous. Balancing and blueprinting doesn't add horsepower, it ensures the reliability and tolerances of the engine, something you definately can appreciate if you race for even a season or two. I will agree that the headwork they have done is *probably* unneccessary as the AP1 head flows ridiculously well already, but they basically have I/H/E, throttle body, crank pully and a tune on a 2.2L engine w/ 13.5:1 compression -- I would say that they've done well. Their other car is doing 320hp, so this is not their ultimate build anyway, and that car is still a work in progress as I understand....

 

I didn't say that balance and blueprinting was going to hurt anything, I dont know where you pulled that out of. The fact that it took them 13.5:1 compression to get to 300hp leaves me less then impressed. There is an F20C displacing 2.1L with no increase in stroke from a factory 2L making 340hp on less compression using NO JDM parts what so ever. In fact he is running cams and a header from California and a cylinder head modified in Texas. We have made more power NA in America using Honda production engines then any tuning company in Japan short of the factories.

 

Running 13.5 CR seems a little high to be "reliable" by my definition. Anything on race gas @ $12/gal pretty much removes it from the DD category(at least on my income).

I have 3 track days on my stroker running premium unleaded. I have another 2 days at the end of this month. Inline is going to pull the rod caps and take a look-see. I'm sure everything will look

 

[QUOTE=S2K9000,Mar 3 2007, 05:25 PM] For me I would prefer to buy from a company like J's.

 

[QUOTE=S2K9000,Mar 3 2007, 07:24 PM] I don't think your statement is accurate regarding a 9,000 RPM rev limit on a 2.2L, however if you strongly believe it to be true, can you provide me with documentation of this claim?
