correct me if am wrong but isnt the 02-04 type-s rated at a claimed 200hp from the factory? and 05 type-s is at 210hp then 06 type-s 201hp??? i know this is all claimed hp not to the wheels but am asking cuz a dumb friend of mine thinks i dnt know my own car even after i showed him the hp rating s on a magazine. he claims dat 02-04 are at 210 and 05-06 are at 200hp....plz prove him wrong thanks guys

 

K20A2
• Found in:
o 2002-2004 Acura RSX Type-S and 2002-2005 Honda Civic Type R (EP, European)
• Displacement: 1998 cc
• Compression: 11.0:1
• Power: 200 hp (149 kW) @ 7400 rpm
• Torque: 142 ft•lbf (193 N•m) @ 6000 rpm
• Redline: 7900 rpm

K20Z1
• Found in:
o 2005-2006 Acura RSX-S
• Displacement: 1998 cc
• Compression: 11.0:1
• Power: 201 hp (150 kW) @ 7800 rpm (sae NET Rev 8/04)
• Torque: 140 ft•lbf (194 N•m) @ 7000 rpm (sae NET Rev 8/04)
• Redline: 8400 rpm


I thought I heard something about 210hp as well, but the only thing that comes close to that is the k24a2 @ 205hp or the k20a @ 220hp. Everything else is less (except the k23a1 turbo of course )

 

the k20z1 had the 210hp in 05, but in 06, honda had to use different sae ratings so the number displayed to the public is less, but the engine did not change.

 

bobochan is right. the a2 is 200hp, the z1 is 210 hp in 05, 201 hp in 06 using the newer ratings

 

Nice, I stand corrected. I just got that off wikipedia, hah!

 

thanks guys that pretty much proves my point

wikipedia can never be trusted ... keep that in mind ... i learned that the hard way ... lol

 

btw where can i find the engine code for the rsx-s? where is it? thanks. i didnt want to end up buy a 05' with a k20a2 instead of k20z1

Engine code is on the backside of the motor, not the front. Don't know why they did that but whatever. Only way you're going to end up with a k20a2 in an 05 type S is if the guy swapped it himself. I don't see why but that is only plausible way. the 05-06 come with the k20z1

damn that sucks, gon' have to stick my head over too see the engine code.

 

well there's an easier way to see it, forgot to mention. Just look on the left side of the valve cover, there's a sticker that has your engine code.

 

So is the z1 an improvment over the a2?? If so in what way??

 

more aggressive cams, and shorter gears.

Well other than that are there any major diffrences?? Just cams?? Why change the block code then??? Im curious because im in the market for an 03-04 RSX type S

 

A-spec lip kit, rear tail lights, better leather seats. I dunno why they changed the engine code, ask honda. I just heard they have more aggressive cams then the 02-04 but i know they have shorter gears then the 02-04 type s.

 

the people at parts department told me this at the acura dealership that it is a change in the cams but honda always does stuff like this when it comes to a slight change in the motor they will change the code hope that helps you out some

05-06s have something similar to the type-r cams
i don't think they are exactly type-r cams because they have a different part number
but yes, they are more aggressive then the 02-04s

and you are correct, the gearing is slightly different
the final drive on the 05-06 are similar to the 06-07 si's

 

Here are the changes from the 04 to 05 TypeS with the engine specific stuff noted in bold:

Power is increased to 210hp at 7800 rpms (SAE revision 201hp for 06 model)
Torque is increased to 143lb-ft at 7000 rpms
Final drive lowered by 8.6 percent to 4.77 for quicker acceleration (same FD as JDM DC5 Type R)
Single cone carbon synchronizers for 5th and 6th for more direct shift feel less mechanical loss in transmission
High performance camshafts added (Same PRC cams as JDM DC5 Type R)
Valve lift on intake side increased by 5 degrees and exhaust side by 10 degrees
Diameter of intake duct enlarged 11 percent from 63mm to 70mm. (PRC part number, Same as DC5 Type R)
Higher flow exhaust system, w/ larger tail pipe increased from 60.5mm to 70mm. (Same B-pipe as DC5 Type R)
Higher flow catalytic converter by reducing density of ceramic substrate, flow increased from 95L p/sec to 98L p/sec
Upgraded Clutch Pressure Plate (PRC part number, which is DC5 Type R)
Upgraded Main Pulley (PRC part number, which is DC5 Type R)
Additional engine mount damper added to reduce rocking and isolate powertrain NVH from passenger compartment.
Standard 17" alloys with 215/45/R17 all season high performance tires.
Stiffer rear springs and more compression and rebound damping front and rear.
Larger more rigid strut tower bar, increases body rigidity.
Horizontal and vertical rigidity strut tower bar reinforced by 13 percent and 26 percent
Caster trail increased by 65 percent from 9.9 mm to 28.6 mm ( more predictable steering at speed)
Camber angle increased 50 percent for maximized tire contact during cornering.
Center of gravity lowered by 7 mm
Dampers receive new damper seals to improve ride and drastically reduce static friction
Front compliance bushings adjusted, 4mm longer stroke and 20 percent lower spring rate
Front damper bushings replaced by bearings to decrease friction increasing response and steering feel.
New inversely wound springs for better steering precision while cornering
Front stabilizer bar increased from 23 mm to 26.5 mm and wall thickness increased from 2.8 mm to 3.0 mm.
Rear stabilizer bar increased to 21 mm
New relief valve in steering rack achieves linear injection volume.
Powersteering pump flow increased 7 percent, creating increased hydraulic pressure.
Kickback reduction valve added to reduce steering kickback when driving over bumps or objects.
Quicker steering ratio, 14.9 vs. 15.1:1 from 04
Steering column reinforced, increased stiffness by 45 percent for even more solid steering feel.
Brake pedal stroke reduced by 5 percent for shorter stroke and more linear brake feel.
New flange added to brake pedal to increase pedal rigidity by 50 percent.
Larger diameter master cylinder to increase brake fluid displacement and enhance brake feel.
Brake performance improves 5.4 percent in dry and 9.7 percent improvement in wet.
New fuel tank shape optimized to reduce fuel evaporation, lowers evaporative emmission by 75 percent
New LEV2 rating
New more aggressive front bumper, triple beam headlight, reworked grill.
New redesign rear bumper, new thicker exhaust finisher and taillight assembly, continues the impression of power and speed.
New deck lid spoiler intergraded
New aggressive sculpted side sills
Coefficient of drag and coefficient of lift were improved with the restyle, making the RSX the most aerodynamic coupe in its class.
Ratio of lift between the front and rear were improved, making the RSX more stable at high speed.
Rigidity of body increased front and rear in key areas, including mounting points.
Front rigidity was improved 15 percent with a thicker fitting base.
Rear cross member improved by 21 percent.
Additional insulation material in roof and doors reduce road noise.
NVH reduced with lightweight, noise absorbing insulation to the roof and doors.
Wind noise reduced by additional weather stripping between gaps on the side mirrors.
Front seats optimized with thicker cushions and deeper side bolsters with upgraded leather. Seats get new double knit material.
Thickness of urethane padding was increased for firmness and support during acceleration and 3 decible reduction in vibration.
New Titanium headrest inserts.
Chrome and titanium-look accents added to key spots in cockpit.
New sporty material applied to roof lining, A-pillar garnish, quarter panel garnish and door lining.
Enhanced rubberized geometric-grain material added in 05 to the instrument panel for a more sporty yet refined look.
New black on white background gauges, trimmed with titanium accent.

miketypes, great info!

 

Great info if you labeled the correct years, i believe you are referring to 05-06 not 04, 05. Those are two different gens, 05-06 is the 2nd gen typeS which you are referring to and 02-04 is the 1st gen.

Learn to read....changes from the 04- (to) 05 TypeS.....

I am very well aware of the model years and changes for the RSX having owned both an 02 and 05....

 

learn to articulate your sentences....If I couldn't read i wouldn't be posting in the first place. Wait...... yep my telepathy network is still not working so i don't know exactly what the hell your thinking. The way you have it posted it sounds like you are referring to both years being the same and dashes mean thru not to.

 

I edited my post, are you satisfied now?

 

 

wow, thanks for that info, that is great stuff. If I ever have to replace anything in that list on my 02 I will make sure I get the 05 part instead.
