Hey
Doing a bit of research on the 2 k20s and wondering what makes the difference in peak torque on both of the engines??? The k20a get peak at 5k while it takes the k20z at 7k rpm to it peak torque. I know the k20s apparently has 2 different types of speed sensors and the they both have itr cams and the k20z has different exhaust cam. Did i miss anything that contributes to that and the slight power difference???
K20z = better than k20a
K24a3 shits on both k20's with torque from 4400rpm just wow!!!
Factory tune
any more things i missed?
most of the internals would make a slight power difference, the k20a was made in early 2000s and k20z in 2006,
lol such crap info here
depends which k20a your talking about.
There is the AUDM K20A2 147kw @7400rpm peak power , 192nm @6000rpm peak torque .. 11:0 Comp Pistons, redlines 7800rpm fuel cut at 8200rpm
JDM K20A 160kw @8000rpm peak power , 206nm @7000rpm peak torque, 11:5 comp pistons, redlines 8800rpm
AUDM K20Z1 , 154kw @ 7800rpm peak power, 194nm @7000rpm peak torque, 11:0 comp pistons, 8300 redline
the k20z shares the same camshafts as the jdm k20a, is quite similar with the exception of the 11:0 comp pistons
the audm k20a2 is watered down version basically
Type r motors also come with dual valve springs
Z motors are only run singles
as usual, jap spec gets all the goods :(
But i know the k20z has a more restricted exhaust compared to the type rs?? Potential wise shouldnt it be as good as k20a?
Wrong.Quote:

Theres a few threads about this
well get rid and replace it with the type r probs be same as the k20a2?
Anyways i keep thinkin jdm engines are better because they have octane 100 there so they can run high compressions.
thanks for the help though
Between the K20a2 and K20z1 are these differences noticeable?
i doubt u could notice any difference between any, i couldnt tell the difference at all between a k20a and a k20a2
Performancewise ?? or LooksQuote:

Im with mullens, they were the same. Figures don't mean shit. Why did honda but the K20A into the type r if the k20Z and the K24 are both better then it. I think someone has been feeding you all crap. The K24 would be a better motor to build no doubt, but thats after you take all the good stuff off the K20A which is the oil pump and head. Which leaves you just a bottom end. So to me the K20A is the better option because if you want more power, buy a cheap K24 block which is cheaper then trying to source a heap of K20A parts. Also the standard K20A package is enough, it really is. Having said that, i didn't read any of this online, i learnt it first hand. Sooooo its probably best not to take anything i said as fact. Also I'm not trying to peddle wares so that there also says don't listen to me.
i mean sitting in the car and being taken for a drive/ drivingQuote:

Those Butt dyno sure are quite accurate arent they?.
my experience is from noticing trends on the output of the motors AUDM DC5R, DC5S, EP3R when being run on the same dyno..
The dyno outputs compliment the factory claimed figures..
I found the AUDM K20A2 was more powerful than the JDM K20A
This was a race tested on the drag strip with a AUDM K20A was in a full stripped out EF CRX and the JDM K20A was in a EP3R with a full sound sytem, 15" Sub woofer and 20" chrome rims
So I am certain these tests prove correct.

Kpro Is not mandatory. I dont know about small differences but having higher compression and bigger camshafts is always going to be an advantage regardlessQuote:

No, not noticeable.Quote:

7kw difference.
DC5 Type R weighs 1160kg i believe? Feel free to correct me
DC5 Type S Weighs 1230kg i believe also.
Hope this helps also.
Not noticeable to your average driver i'd say, nor any of us who drive one of these cars in my opinion
If you want the full details, use the search engine provided on OzHonda and look up Type R Vs Type S, plenty of information there
I dont understand. They ask for a difference between the 2. I say i didn't notice a difference and that i thought they felt exactly the same. So because i think that they are the same because A i have driven both B i have raced both with the said front end swapped civic and i didn't notice a difference between the 2 platforms, that this makes me un qualified to comment on the situation? Where as you read on the internet that this motor puts out this much power so there for without a doubt you are correct. You also did dyne testing in which you figured car A produced this much power then car B produced this much. This was done on the same dyno as you stated. So if your car A made 400Hp and your Car B made 450hp then the car with the most HP will be the better one correct? A result that you are willing to base souly on figures? I will glady tighten the shit out of my seat belt as i believe experiencing something first hand is a better judge then just looking at numbers.
Okay iVTEC ninja master bob
A) Your motors were obviously modded as it is in a K Swapped Car , probably with upgrades which will tighten the gap between the motors ie JDM ITR CAMSHAFTS, KPRO, RBC intake manifold etc etc. B) A Motor that makes more power and torque than another motor on the dyno on the same day, is obviously better , we are only talking about the motors here, if your going to start comparing similar laptimes this is just folly , as there is a lot of factors will come into play about and it is not resting entirely on the motor..
C) Keep tighting the shit outta your seatbelt as im not only reading shit off the internet, i have experienced a shit ton of Kswapped motors, Standard motors and i have
come to the conclusion the JDM K20A variants are a better motor all round..
Regards
NOTAJK
I don't get it, all along i said the K20A was the better motor IMO. Was there a difference that i could see, no. That has been my point from the start.

its like b18c7 with gsi gearbox

there's heaps of threads with DC5 owners being pissed the EP3 makes more power as its meant to be the little brother not the boss lol
i dont see how that would be the case because they have the same motor and the same gear box (ratios are exactly the same) besides being stamped y2m3 (dc5) npr3 (ep3)Quote:

Adrian (TODA) also said in his experience the EP3's do a tad better than the DC5's stock for some reasonQuote:

Or am I confusing this with something else?
Nope only oneQuote:

Not true,theres a UK/EDM also
Not really the same carQuote:

That's what I thoughtQuote:

I suprised they called them TYPE-R not having LSDQuote:

Ala jap k20a vs aus k20a power difference. Wonder how those two compare to eachother.Quote:
