Our a3 ISNT stronger then the base RSX, sorry to break it for you... did you finish reading the whole post? Everyone was bashing him for considering swaping his base rsx motor for the Si motor, which doesnt make any sense to me either.:rolleyes:

[04rider]

YES SIR, STARTING ON THE LAST PAGE. HONDATA EVEN SAID SO.

stupid people never do smart things

There sure is a lot of flaming on clubrsx...

The conclusion was, the Si's K20A3 is a better candidate for modification, because the base RSX's engine loses power in the upper range due to the dual stage intake runners, and Hondata only raises the rev limiter to 7300 instead of 7600.

[04rider]

"There are plenty of other reasons. The EP tranny has the advantage in gearing, and the final drive is 4.764 compared to the base's 4.389. The throttle body is also different. The single runner intake manifold does indeed make a big difference in the upper RPMs. When I first started modding K-series motors I also questioned myself about Hondata's 7300 rev limit for the base and 7700 RPM rev limit for the EP. They're the same motor. Well I contacted Hondata and they emailed me back with a great explanation of the Base vs. EP manifolds. The only reason why Hondata limited it to 7700 RPMs is because of the stock valve springs, the A3 in the EP will continue to make good usuable power even past 7700 RPMs with i/h/e and Hondata but stock valvetrain limits that. The base on the other hand, power falls off very sharply after 7300 RPM that it'd be worthless to rev it any further."


"The si also has a fully counterbalanced crank, the same one that the type s has. The is also why the si can produce more continuos power throughout the rev range. The intake manifold is not the only difference." -CLUBRSX MEMBERS

i always thought that our crank wasnt balanced....which is why we have 2 balance shafts instead of 1...im confused lol

[BlairSpeed]

hmm, so in stock form the base RSX is stronger, but our a3 responds better to mods, especially on the top end, making it stronger engine. correct?

whats a balanced crank?

[Jester]

umm..yes we do have balancing shafts

"In addition to its outstanding power and efficiency, the Civic SiR engine has been engineered for class-leading smoothness and refinement. To that end, such NVH-reducing features as a balancer shaft (integrated with the oil pump); highly rigid, ferrous-carbon inserts in the main bearing caps (for added rigidity); a one-piece crankshaft carrier; and a silent chain cam drive are incorporated. "

The type S has a counterbalanced crank shaft, ours as well as the base is not fully counterbalanced. A member brought theirs to be balanced and found it was out by 11g.

top of the video feed's about balancing system

the other link was the Canadian Site this one is US
both show that the SI/SIR has it

I have heard that the A3 with a turbo is better then a a2 becuase of the lower compression ratio.

[Graywolf]

Yes, but our a3 is worse than the rsx a3.

I think that's what this whole thread was about. As someone posted in this thread somewhere above, the A3 in the base RSX is slightly more powerful stock for stock than the A3 in the Si, due to a bit more torque, etc. But when it comes to potential and high-end modifications, the Si's A3 is superior.

I've read about that a while back. Hooray for the a3. I'm proud of it and the power it produces after some nice mods.
