just wanna post this up so this guy can read your opinions about these two motors... this guy says that b18c is faster than k20 (cuz hes getting b18c motor swap in his 92 tegra) .. im like whatever he says. if its fast then good for him. YET in stock-wise WHOS the king???? i hope k20 is the answer. lol

 

the jdm b18c from the type r are rated at 200hp/134 tq while the k20a2 is rated at 200hp/142? tq

whatever, but the point is, they have the same hp with the k20a2 having more tq.

 

there is more to an engine than just hp/tq numbers. simply put, the k20 > b18c. if the b18c > k20, then they would of had kept the b18c around and just try to make it to emission friendly.

 

i knew k20a2 had more torque.... its K>b simple as that.. hands down.

 

The K20 is better in every aspect; More tq, better valvetrain, better powerband, iVTEC, and all while emitting less polutants. K20A2>B18C

 

a b18c in a 92 teg will prolly out run a stock rsx. if the rsx had i/h/e then it would be a close race. put a k20 in a 92 teg with cams head work and a good bottom end there would be no contest between the two.

if you knew the stats then why did you post

 

well you gotta remember that the teg is a lighter car too i know a guy who put a stock k20a1 into a EG hatch and that hatch ran 13s all day at the track

 

if you're comparing the motors ONLY... K20 &gt; B18C
it's the matter of the weight also... Then driver.. blah blah. Play with it
Overall, K20a2 will be faster. (motor only)

 

when u guys are talking about the hp and tq numbers u guys are talking about at the crank not at the wheels and that is what really counts.

 

Iv seen dynos where a k20a2 puts down around 160-165 whp and a b18c R puts down about 170whp. Also the LSD which comes with the b18cR motor makes up for the 8lbs of torque it lacks, so there you have it, a b18cR&gt;k20a2 Both stock

The Race: The B18cR pulls right off launch b/c of the lsd and continues to pull becuase of its crazy top end power, oh and trust me a b18cR pulls hard oh a RSX from a roll. If you dont believe me try it for yourself

Also, the b18cR is a fully balanced NA Race engine capable of handling high revs for decent amounts of time where the k20a2 is just another engine in every Rsx out there which doesnt like to wind up to its 8k reline too often(except the K20R)

^ is the B18CR honda's new imaginary B series?

Also, the K20 has no problems revving to 8k anytime you need it to.

Nope, since the b18c's in japan dont have a number after the C like here in the US (B18C5), People refer to the Type R motor as the b18cR so people dont mix it up with the jdm gsr motor. So if the b18c_R is making you uncomfortable, just change it to b18c5

 

ur dyno numbers are a lil off...the k20a2 actually dynos higher than the b18c (R) stock for stock.

Thats what the dyno says, you got your numbers twisted buddy, your probably thinking of a usdm b18c5 which makes about 164whp a jdm ITR makes about 170whp,

Im not going to respond to this thread anymore, so have fun with the dyno

 

Why do people insist on screwing this up? We are not talking about an integra vs. an RSX-S. We are talking about the B18C vs. the K20A2, in which case the K20 will gladly hand the B series motor it's ***. All the B18C has is top end power, before 6K it's a torqueless sloth. The OP said the motor is going into a DA in which case the K20 will outperform the B. Im not saying the B18C is crap, the K20A2 is just a better motor. the K20 has a better powerband and more tourque, handsdown, ITS A FACT! K20&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt ;&gt;&gt;B18C

Motor for motor, the K-series has a few advantages over the b18c, but not much. The b-series has many years of R&D behind it already with the K-series catching up fast. Being considered the best N/A 4cyl in the world right now also says alot for the potential of the K series.

I imagine that in that lighter frame, the K-series would bring out more power than the b18c in this case. The tuning potential of the k-series is proven. It also responds better to mods than the b18c.

It's a drivers game I'm thinking. One of the import mags just did a shootout of two EG6's, one with a b18c the other a k20 swap, they ran about dead even. one was quicker, the other more powerful. It was like a 3whp lead. Either choice he goes with will be great. If price is an issue, I'd go with the b18c or a H20. If not, pop in that k-series and see what develops. Few guys on CRSX are boosting out around 400-450 on stock internals, one guy got into the 600's before blowing it up. Don't think a b-series can do that stock.

 

this is like comparing apples and oranges guys come on. . .

i was reading along the post and since everyone seems to favor the k20 i would like to share my unbiased opinion. these 2 motors are very great motors, but they did so a shootout on the Septembers issue 06 of sports compact car.

both motors having pushed closed to the same hp around 200, regardless of tq. the b18c was put into a eg si chassis and the k20 a eg cx chassis. 1/4 mile times were 13.9 b18c and 14.2 k20 if i remember correctly. having said that after all the road test that they did, the b18c was considered to be more of a 1/4 mile car as well a kind of 'race' car rather than a a daily driver. the k20 on the other hand is a kind of car that works well with road racing and a more of a 'daily driven' car.

in conclusion there was no real winner both cars and engines having remarkable numbers in its particular area giving both setups a draw.

 

stock for stock - b18c5 FTW

but..

k series have wayyyyyyyyyyyyyyyyy more potential. responds better to bolt ons and and built stronger to handle more ish

 

we just speaking about k20a2......what about the higher spec k20a motor?

 

Anyone who posted in this thread that has both motors, raise their hands.



If not, then please stop spewing heresay that you've read on the internet.

If we're talking about a stock JDM DC2R motor (B18c) vs a stock USDM RSX-S motor (K20a2), the B18c is definitely more geared toward performance. And more than likely, in the same lightweight chassis, the B18c will beat the K20a2 around the track.

One you start talking about mods all bets are off and the subject becomes a pissing contest at that point.

 

i drive a type-s my bro drives a 2000 type-R and he himself will tell you he wouldn't mind having a k20 under his hood. and screw the k20a2 lets talk k20z1 . all i have to say is that its hard comparing both motors because they sit in totally different cars around the track i know the dc2 will kill the rsx because of the double wishbone suspension but in a straight line it would be a much closer race. also a stock k-series is very restricted by a crappy header and exhaust. but if i had to pick which motor was going into my dc2 i would go k20 over a b18c5 because i have seen more k series cars in the 12s than built b series cars

H22 FTW!!! Anyways I hear this all the time but every single "race video" (like best motoring)that I have seen always has the DC5 out handling, out braking, and generally outperforming the DC2
