i'm plan on respecting evreyones opinion, but, this is utter jibberish. LOL. rod through the block? piston through the hood? if anybody enocounters these type of catostrophic implosions has nothing to with the fact that the motor is b, d, f, h or k. everybody tries to find the flaw with buying a b. how about an oiling issue with k20's revved above 8700rpm? how about acura switching from rsx (k20) to tsx (k24) in the speedvision championship? jdm k20-r has huge torque? for all you veteran football enthusiasts i say this is the voice of the almighty Jim Mora Sr.....Playoffs?????? LOL. sorry, i had to drop that one. k20's make decent torque but, huge is str8 madness. 22's make 144wtq stock. anyway, k's have more potential, make more power. but, don't tell me that they are better, because a few years never tells the whole story. lastly, there was a thread i read last year on HT about people making big numbers with k's, but, run a bit slow (in relation to the power that they make) when compared to less hp B series motors. i'll try and find the link

meh. it's a little over the top but still. for a HONDA motor. the k makes huge torque as oposed to the 110 the b16 makes., and have dirty potential.

i wouldn't knock on k that much. honda obviously developed it for a reason. the only set back is that it's pricy to put into an eg, ek, dc, or w.e. k's aren't bullet proof motors either. they don't go well with boost, the internals can't really take much. a k24/k20 combo has huge torque, a k20 has nice torque.

i've changed my opinion from no to YESSSSSSSSSSSSSSS. i just drove in a type S turbo'd and omg it was the best experience of my life so far!

imported_alwaysoverkill

its the 1.6L vs 2.0L and effeciency....then I checked per 100cc (i'm bored I know) and....

B16 makes 6.94lb-ft of torque per 100cc
K20C makes 7lb-ft of torque per 100cc
K20R makes 7.9lb-ft of torque per 100cc

and for comparison

If the B16 was actually 2000cc with the same effeciency it would make 139lb-ft of torque and 200hp where as the K20C from the RSX-S is 140lb-ft of torque and 201hp.

So the B16 and K20C are actually equal effeciency and it really means that if the B16 were 2L it would basically be the K20C haha



And for further interest:
K20R = 7.95lb-ft of torque per 100cc or 79lb-ft/L (JDM)
S2000 (2L) = 7.65lb-ft of torque per 100cc (2L) or 76.5lb-ft/L (USDM)
B16B = 7.38lb-ft of torque per 100cc or 73.8lb-ft/L (JDM)
S2000 (2.2L) = 7.36lb-ft of torque per 100cc or 73.6lb-ft/L (USDM)
B18C5 = 7.22lb-ft of torque per 100cc or 72.2lb-ft/L (USDM)
H22A = 7.1lb-ft of torque per 100cc or 71lb-ft/L (USDM)
B18C1 = 7.11lb-ft of torque per 100cc or 71.1lb-ft/L (USDM)
NSX = 7lb-ft of torque per 100cc or 70lb-ft/L (USDM) - same for 3L and 3.2L
K20C = 7lb-ft of torque per 100cc or 70lb-ft/L (USDM)
B16A2 = 6.94lb-ft of torque per 100cc or **.4lb-ft/L (USDM)
D16Y8 = 6.69lb-ft of torque per 100cc or 66.9lb-ft/L (USDM)
D16Y7 = 6.44lb-ft of torque per 100cc or 64.4lb-ft/L (USDM)
Viper = 6.44lb-ft of torque per 100cc (8.3L SRT-10!!!!)
which is 64.4lb-ft/L
Ferrari = 7.98lb-ft of torque per 100cc (Ferrari F430!!!)
which is 79.8lb-ft/L

The last two show how good the Honda's are for a NA engine, they just lack the size to show how its done. So the new NSX should solve that.

S0 K20C and same effeciency as B16 and if the B16 were 2000cc it would be exactly the same as the K20C.

^^^ Thats a great comparison bro. Not everyone can see the big picture so that is very helpful.
I will also agree with your previous comment on turbo'ing the D. For about 5k invested in a D, its possible to bring it close to 300whp. Now if you invested all 8k or however much you want to spend on a K swap, its realistic to be in the 400whp area.
So in my opinion it is not really worth it. There is an exception though, and that is if your looking for EXTREME power. Besides that a regular D or B will do. I doubt very many people need 300+hp on the street in a civic, which is attainable without the K.

Nova_Dust

That means, JDM B20B only has 6.65lb-ft of torque. Nothing to be crazyed about, for sure.

Good info alwaysoverkill

NO, not worth it yet, but will be soon

k20a type r has more torque than 158 does it not?

imported_alwaysoverkill

Not from the info I got. K20C from the RSX-S is only 140 lb-ft of torque while the K20R from Honda Integra R is 158. It makes 20 more hp and 18 more lb-ft of torque, thats a pretty good torque increase.

imported_Spiderman

There is no such engine as the K20C...
The engine out of the RSX-S is a K20a2

imported_SaYjAiBaO

f*ck the k20a2, get the k20z1 from the 06 si that comes with lsd . i don't think they have mounts for it yet though because i think the tranny mounts are different than on the other k's. the k20z1s are more powerful motors too. i can't remember where i found the graph but it was somewhere on h-t when they did a comparison between the k20a2 and the k20z1. i remember reading someone saying how the SAE standards changed so that's why the K20z1 shows a lower output but the graph showed otherwise. don't quote me on this though! i don't know how accurate it is.

K20A and K20C. Either way, I took the 140lb-ft of torque for RSX-S from acura.ca

Seems the RSX-S is K20A2 but even still, torque figures are accurate from Acura. Not sure why that site lists it as K20C

imported_Andrey

its k20z3 buddy

the best engine is k24a2 out of tsx and in states its not really expensive at all.

i think k-series engines are not exp at all from what ive seen its just swap with all the parts makes it crazy expensive
but it shud be okay for ep3 right

i looked at car-parts.com and ive seen k20a2 in ontario with tranny going for under 2k CAD...wth why so cheap?

imported_SaYjAiBaO

my bad k20z1 is off the newer rsxs but how do u figure the k24 is the best engine out there? the k24 is a nice block but all you need is just the block. you can get k24 blocks off crvs or w.e for dirt cheap like a few bones. those k20s u see in car parts are most likely not complete. cut harnesses, missing valve covers, etc. i've seen most of them when we were looking for a k series. k swap is just wicked man, the torque is just so much better than a b series i dont care what anyone says. performance wise, it's better than a b series. cost wise, yeah b series are cheaper because they've been around for so much longer. prices will drop soon. a lot of people are going k this year and prices will start to drop on the parts for the swap.

imported_Team Rukus

cuz there isnt a demand for it.

the only thing crv block doesnt have is oil squiters(sp?) only VTEC k-series have it
plus ive read that k24a2 has almost same head as k20a2

the only disadvantage is that because of longer stroke its harder to rev k24 because piston speeds will increase too much.
all k20's have perfect square shape 86x86 whihc is perfect for reving high...but k20a3 is garbage anyways..

imported_SaYjAiBaO

all k series has vtec. the lower model k series had the ****ter vtec compared to the rsx and tsx with ivtec. or does the tsx have ivtec? i'm not sure but all other k series has vtec like the k20a3 off the EP3. the k20 will be good for road racing but the k24 will be good for drag. the k24 will definately not be able to rev as high as the k20 because of the long stroke.
