Now that is a good looking Honda, but I don't think it is the link you intended.

Works for me. Good to see some American engineering in there.

LOL at the K series hater comments. These people don't realize how efficient these motors are and how they can handle 450-500whp all day long on stock internals.

Im not a honda guy by any stretch but if they can handle that kind of power than thats remarkably impressive.

Dear Chase,
See this video...

Stock internals. From what I've seen, it seems like under 400 whp is reasonably acceptable for these engines on stock internals. Again, this is just based on where most of the base k series turbo kits end up whp wise. I'm sure Spent could provide alot more insight as to where you start to see weak links when running high hp.

I'm going to show my ignorance of foreign cars again....that's the 4 banger Hondas right? I think they are good packages, even if they have no torque. I have the 10 Best issue of C&D where this article is. I think they made some good choices. I haven't driven an EcoBoost yet, but I hear they are very impressive. I do love the AMG V8, because they got massive power out of an NA setup.

a lof of 4 bangers stock internals are rated pretty high. not sure about the honda, but i know my crank is rated to 900hp...

Yes, the K-series belong to Honda.
400-500whp and a GT30R or GT35R are what most RSX-S / K-swap setups go with when on stock internals reliably. Turbo kit of choice is either Full-Race or Peakboost for the most part. Most RSX-S guys use stock axles. K-swap's have to use aftermarket axles. K series weakness? It's hard to say with these setups since it's not one thing. Usually, the tranny will take a dump before the motor does and even then they can be pretty tough. For those wanting torque, you can do a k24 or a k24 block /k20 head hybrid. They usually put out just as much torque as they do power. The benefit of the k20 head is the ability to advance the intake cam a full 50 degrees versus 35 degrees with the k24 head. Only thing is with added torque comes added strain on the tranny. The exhaust cam can be advance or retarded with a manual cam gear but 99% of these setups don't bother. For the record, the exhaust can be manually retarded 10-20 degrees depending on cam and pick up power but such cam timing on the exhaust can lead to timing chain stretch/chain slap after a while when coupled with 50 degree advance on the intake. I suppose that would be fine with a stricly track setup but not for daily drivers that don't rev pass 9k rpms anyways. For those who don't know, the intake cam angle on k series motors can be advanced through software such as kpro or flashpro depending on load/rpm. With 50 degrees to play with, you are basically guaranteed to make as much power as possible throughout the entire rev range and a flat torque curve.
Yes, the new civic si uses a K20z3 motor. Hopefully we should be seeing some nasty things out of that chassis now that Full-Race introduced their kits for the new civic si.
Side Note: These motors can be very time consuming to tune. There are a total of 10 ignition tables and 10 fuel tables based on cam angle (0,10,20,30,40,50 degrees x 2 for each cam profile). Half of the tables are on the low cam and half are on the high cam (a.k.a vtec cam). Although time consuming, we obviously take the time to tune the cam angles but not everyone does for whatever reason.

Did a quick google search. Perfect example of what I was just talking about. Not a full-race or peakboost but still a sidemount.

Very interesting......My love for V8 racket aside, I have enjoyed seeing ya'll tune up the various cars you've shared on here. I find your E85 work fascinating.

Why thank you. We usually try to make our threads informative when possible.
