What gives the RSX-S 40+ hp then the baseline rsx???
After reading through some old magaizes last night here at the house(honda Tuning) i read the article that HASPORT did in a 7thgen sedan on a k20a2 swap. After reading the article and more stuff i came to a question that i wondered about. What makes the k20a2 engine so much more powerful then the k20a??? i mean they are both i-vtec and dohc, so what gives the k20a2(rsx-s) 40+ hp then the k20
The RSX-S whp is 200
the baseline whp is 160

Compression bump, True DOHC VTEC (Base is variable intake only), higher lift cams and a better flowing head.
Oh, and they don't make that in WHP
Those numbers are at the crank. The base makes about 146 at the wheels, I think the S makes about 170.

Rep Power: 0 The K20A2 has a higher redline, and has i-VTEC on both the exhaust and intake valves (K20A3 only has i-VTEC on the intake valves). The K20A2 also has higher compression and all the goodies to support the extra revs / more power (oil squirters for each piston and a fully balanced crankshaft from the factory).

Rep Power: 350 The motor in the Base RSX is the same motor in the SI. The K20A3 has i-Vtec on the intake cam only and a lower compression. The K20A3 compression is 9.8:1 while the K20A2 compression is 11.0:1 I like the lower compression in the K20A3 in my SI for the fact that it is better for boost. Plus Vtec doesn't really matter when you go FI.

look at the torque figure...

Rep Power: 350 The differyyyyytttttttttttttttttttttttttttttt4eeee6666 666666666666666666666loppppppp
That was from my cat walking on the key board while I was typing. LOL.
Anyways, the motor in the base RSX and in the SI are the SAME motor.
There is one difference though. The K20A3 in the base RSX has a three stage intake manifold. Hence the reason it is plastic vs the one on the K20A3 in the SI.
Heres a few pics.

Rep Power: 0 The highter compression ratio is another factor too, it recomends in the owners manual to run 91 or higher octane. Another interesting point is that the base RSX uses 5W20 motor oil and the RSX Type S uses 5W30.

Rep Power: 0 you guys are all wrong.......geesh, I had more faith in you guys, it has nothing to do with the difference in compression, the intake cam and the exhaust cam, it all has to do with the cool S in the back, that's where all the HP is drawn.....HELLO!!!!!!

Rep Power: 292 I was positive that the type-s was the K20A2, and that the base RSX and SI were the K20A3?
you guys are saying the opposite?
dang...have I been wrong all this time? lol!

Rep Power: 292 Interesting.
I believe the type R is also known as the "K20AR". I've seen it for sale, and people use that engine code. It might just be a selling tactic, though.
cool, thanks for clearing it up!

Rep Power: 0 The K20A does not have 220 HP. That's 220KW which is not equivalent to HP. In horsepower that's 217HP. That goes for the CTR, too. It's not 215, it's 212HP.
EDIT: And JDM engines do NOT have a # following the 4th character. Techincally, all DC5 engines are K20A. USDM engines get i.e. A2, A3, etc. K20AR, B18CR... the R is just for clarification... kinda like DC2R and DC5R.
