I've heard alot of things about k engines and most of you know about the information about the k series on wikipedia. Link (http://en.wikipedia.org/wiki/Honda_K_engine)

First of all, I have always thought the FN2R (k20z4) is a more powerful engine than that of the DC5S (k20z1) and would get my ass handed to, however wikipedia has indeed proven me wrong it terms of engine torque and power.

Secondly, which k24 engine is everyone referring to when they want a transplant as I find no k24 engine more powerful than the jdm k20a engine. The K24A3 in the (aus) euro is rated at 189hp and the K20A is rated at least 212hp (EP3) unless of course the end result in power is more, bolt-ons against bolt-ons.

When people refer to a K24 transplant it's usually a K24 bottom end with a K20 head (frankenstein), which gives you the K20 power but adds the big beefy torque of the K24 throughout the rev range.

It's not always about who's got more HP, it also comes down to the torque through the rev range and how the power is put down.

Well if you know the history on Type R's then you should know that K20's are part of the Type R line which are the worked performance motors out of the Honda factory.
Where as the K24's are standard i-Vtec motors. More of an economical motor and not worked from the factory's of Honda.

2.4 litre vs. 2.0 litre.

Look at the torque specs for each engine.
The 2.4 is more torquey.

Both are great in there ways.

Which JDM K20A though?

EP3R/DC5R
CL7R
FD2R

So what they both peaked at the same power but the k20a had a more gradual delivery???

Looks like shorter Gear ratio's on the K24?

your wrong, you cant rev the K24 that high, hence the lower kph

k24a3 power comes early compared to jdm k20a
more torque too as you can see.
very similar peak power

Cool, but what do u think would be better, rebuilding a k20z1 with a stoker kit to 2.2-2.3L or using a k24a3 as a base motor and working of that??

K24a3 base, The heads on these have just as much potential as any k20 head, Just needs K pro ECU to take away down tune. If your looking for one get a 06+ engine because the cams were improved.

The k24 block is just a longer stroke that's why you can't rev as high because the piston speed at say 8,000rpm on the k24 would be the same as the k20 block at say 10,000rpm roughly.

K24 transplants don't usually use k20 heads. A K24 transplant is just known as a K24 transplant. A Frankenstein transplant is known as a K20/24 referring to a K20 head on a K24 bottom end.

Eg. Yonas car is only a EGK24A but its only using a complete stock k24 (now with cams). Then from your knowledge you'd be saying Yonas' car is using a frankenstein which is false.

Where in my post did I say Yonas' car is a frankenstein?
My post said "USUALLY" which is the trend in the USA, is to use a K20 head on a K24 long block for better fitment (don't need to cut the hood reinforcement like yonas has).
There is nothing usual about yonas' car, it's a special beast that's been a long time in the making.

The external dimensions of a k24 head and a k20 head are nearly identical. I fail to see how using a K20 head on a K24 block would give you better clearance to the underside of the bonnet.

You said USUALLY K24 transplants refer to k20/24 Frankenstein. If you read what I said using it as an EXAMPLE: from your knowledge you'd refer to Yonas' as a Frankenstein from what you've previously stated.

If you were actually on www.k20a.org you'd know that K24 transplants are known as K24 transplants and Frankenstein transplants are known as frankenstein k20/24 two completely two different things. And a K24 is NOT usually known as a Frankenstein. Not everyone uses K20 heads on K24 conversions.
