That's from wiki. Anyone can google it. BTW, that entry for the K24A3 was made by me. :D I just updated it a little more.

Moving to the noob section.

It makes less power than the 3.5L SOHC VTEC engine in the MDX, but still drinks just as much petrol...

[fatboyz39]

good info!!

[Mattski_VTIR]

I was under the impression that the K20A2 (Aus DC5R) Redline was lower than the K20Z1, around 7900?? This is just what i remember seeing on the Dash

Wiki info is typed in by normal ppl. And I guess the guy who did the K20A2 one was in the US. You can even edit it to say "Redline: When I feel like it"

[Mattski_VTIR]

Heheh Cheers, maybe the poster can update the info so its relevant to Aus? RSX-S to DC5-R ... Type S etc

[aaronng]

You can edit it yourself to add an entry for Aus spec K20A2 and K20Z3. Just go to the wiki page for K series.

done :D

is that correct?

ROFLOL, Do it aaronng.............;)


Good info...........

[flipmods]

Good info, just what I was looking for.

Looking at the K24's, would you say the block is the same and the head makes the compression differerences? Or is the rod and piston different too?

[JDMWhore]

LOL cut n paste from wiki.. I feel like i'm back at uni lol

good work

Block is different too.

[Nepolian]

Block is different too.

^^Agreed!

I remember reading somewhere that the A2 block is either stronger or it has stronger rods. Realistically you'd put in better one if you were to mod it. my2c :)

2006+ USDM K24A2 and 2006+ AUDM K24A3 have stronger conrods :thumbsup:

[flipmods]

Thanks. But apart from the strengths of the rods, do they alter the compression as the bore and stroke is the same.

Yes, the K24A2 and K24A3 have higher compression than the CRV and Accord engines (K24A1 and K24A4). They also get cast metal intake manifold, instead of the plastic ones in the CRV and Accord.

Yeah I meant the blocks, lets say a K24A3 head was puton a K24A1 block, will the compression be the same (disregard strength) as the bore and stroke are the same.

Thanks
