RSX Type-S 200hp vs. TSX 200hp, which is superior?

anybody know if the RSX Type-S engine is better or the TSX engine? I've heard that the TSX engine is actually an upgraded version of the RSX Type-S engine with more torque. But right now I'm seeing that the RSX Type-S peaks its 200hp at 7400 rpm while the TSX peaks at 6800, why is that? Does that mean the TSX engine is weaker, since the RSX Type-S engine has even broader range of rpm than the TSX. Someone please educate me in this field. Also, the RSX Type-S redlines at 7900 while the TSX redlines at 7100 what's the difference? Lastly, the RSX Type-S is a 2.0L with 200hp, that's 100 hp per liter, while the TSX is 2.4L with 200hp, that's only 83.3 hp per liter, nearly 20hp less than the RSX Type-S engine, doesnt this mean that the RSX Type-S engine is a lot stronger? any input is much appreciated.

Lemme have a whack at it:

I'd call it different, not "better".
...I've heard that the TSX engine is actually an upgraded version of the RSX Type-S engine with more torque.
I'm pretty sure the TSX engine is a stroked version of the RSX-S engine. Someone correct me if they don't have the same head.
...But right now I'm seeing that the RSX Type-S peaks its 200hp at 7400 rpm while the TSX peaks at 6800, why is that?...Also, the RSX Type-S redlines at 7900 while the TSX redlines at 7100 what's the difference?
It's a strength of materials issue. The longer stroke in the TSX forces higher piston velocities at a given RPM. This means higher forces trying to break the wrist pins and connecting rods. So the redline has to be lowered to compensate and stay safe. Power peak follows.
...Does that mean the TSX engine is weaker, since the RSX Type-S engine has even broader range of rpm than the TSX.
Both put out 200 peak HP. They're both equally "strong" if you want to put it like that. And if you want to factor in torque, the TSX makes more, so it would be "stronger".
...Lastly, the RSX Type-S is a 2.0L with 200hp, that's 100 hp per liter, while the TSX is 2.4L with 200hp, that's only 83.3 hp per liter, nearly 20hp less than the RSX Type-S engine, doesnt this mean that the RSX Type-S engine is a lot stronger? ...
Don't confuse absolute strength with a strenth per amount of size. A HP per liter measurement compares power output with the amount of volume the pistons sweep through (displacement). In HP per liter (sometimes it's called "specific output"), the RSX-S engine is substantially better than the TSX engine (it makes the same power with less displacement). And the S2000 engine is king of the world (for production cars) at 120 HP/Liter.

Anyway, it's hard to say what's a "better" engine. It all depends on what you're looking for. Hope that made sense.

Wow. So you know the specs... in what way are you asking if one is "superior"?

Why would hp/L be a more important spec than pure hp (where they're even)? And don't forget torque. That extra 0.4L in the TSX give it 166 ft-lb compared to 142 in the RSX. That's a 17% improvement.

The RSX revs higher, but the TSX is more useful "around town" at lower revs, from what I understand.

ok bottom line

The RSX-type S is a faster car. Higher revs,alot lighter, more raw HP to the wheels, and much more room for modifications then our TSX. yes we have more torque but the RSX uses it more efficiantly.

But the TSX is overall more powerful(larger heads and engine). if you want quickness- go with the RSX but if you want overall performance and handling-stick with the TSX

"more raw HP to the wheels" How do you figure? Dyno's show there equal with the TSX ahead ever so slightly.

I'm not disputing that the RSX-S is quicker, thats a given. But I wonder how much quicker or slower an RSX-S would be with the K24 or how much slower or faster the TSX would be using the K20.

We know the Euro R uses the K20 Type R motor but I don't think I've ever seen performance stats for that car?

The RSX with the K24 engine would be quicker than with the K20 engine but would suffer at the "track" due to a lower redline. It would increase midrange torque to pull it out of the turns better, plus increase the 0-60 time.

an rsx-s with a k24a2(tsx) swap would be faster than a rsx-s with the k20a2 at a dragstrip. You may notice that all the tuners are now making k24 frankensteins of their civics/rsxs instead of doing like jdm k20a1 stuff because of all the potential there. In dynos the tsx motor is really putting down like 25% more torque through a lot of the torque band, much more than the rated difference. It does have a comparatively weaker top end which would make a difference in a autox/track setting.
One thing to note is the k24a2 has a different head/intake manifold than the rsx-s. It's a single runner setup. It would be very easy for honda to get another 15hp and 10lb ft of torque by going to a dual runner setup. It's probably the upgrade we'll see for the tsx when they decide it's necessary.

Slight weight difference too:

Talking

"stroked"... hmm i should tell my girlfriend that i want my "head stroked" too just playin'....

Thanks so much for all those info Clutchperformer, those were very valuable.

RSX Type-S is still faster than our TSX's, by 0.2 seconds, i would suppose that's because of the higher displacement?
and of the 2 engines, what is your opinion on hp and torque? which one is better in ur opinion?

what is all that K20 and K60 stuff y'all talking about, sorry to sound like a noob..... well wtf, i am a noob, so educate me good

thanks bud

You are still confusing specific output for displacment.

Displacement is the volume of the cylinders in the engine. It is not measured in relation to power. i.e. Litres. TSX 2.4L, RSX 2.0L. TSX has higher displacement.

Specific output is a measure of power per unit volume. i.e. HP/L.

Let me bring another car into this. Corvette Z06 385hp, 5.7L. Specific output is "only" 68 hp/L. It will still destroy both the RSX-S and TSX.

btw, the TSX is slower because it weighs 500 lbs. more.

yea i was thinking about that, given the same weight on the TSX compared to the RSX Type-S, TSX will probably run faster. only 0.2 seconds difference between them.

I have had both of these cars ... say what you will, but at the drag strip the difference is so small that it is just not that big of a deal. However, for those of us that are out of the "rev to 8K buzzing RPM's" to get our power, the TSX is just amazing. It is by far the smoothest delivering I4 that I have even driven. Depends what you want, but for day to day driving I wouldn't want anything less that the power delivery in the TSX K24. In fact, I am pretty sure this will be my last I4 (that isn't coupled with an IMA system )

thanks for all of your opinions, they clarified things a whole lot for me.

lastly, i'm thinking about tuning my car.... aiming for more power. what parts do you guys think i should start with? intake, supercharger, turbocharger...... etc? thanks, i appreciate it.

i like my tsx motor i would like to see the rev limiter raised a little..it feels as if the engine is just starting to pull hard at 7000 rpm...and lower the vtec a lil with more agressive cams

You're very welcome. There's many factors in this, but the RSX is faster mostly because it weighs about 500 pounds less than the TSX.

hey ClutchPerformer,

I'm all puzzled with this Break-In Period, whether to do an Easy Break-In or a Hard Break-In, meaning to not do high rev'ing during the break-in period or to rev up like mad and open up the throttle. I'm totally confused on this subject, some people believe hard break-in's will actually set the piston rings properly, while the dealer's manual says not to have full throttles during the break-in period.... help!

check this article out on hard break-in

Talking Tsx<rsx s

About 45 mins ago I raced an 06 rsx type s with intake,exhaust,suspension,sway bar etc. i was in a completely stock 2010 tsx w.tech package 5 spd auto-manual...he never launched on me,we went from a roll and I stayed about half a cars length ahead of him til I looked down and saw I was doing 120mph and let off as his top end was kicking in much harder than mine thus barely passing me by. the extra displacement makes for better mid range than the rsx-s...4-5 races and I consistently stayed ahead but he was keeping up. TSX's are superior in every way. period.
