They're the same size, so it's mostly in the cylinder head / valve timing system and engine management. The K20 gets floppy cam gears intake /exhaust and two lobe profiles. The regular VE still uses a distributor, while the K20 gets individual coils.

The only problem with buying a honda, is that you end up with a honda - Jeremy Clarkson.
The people that choose Honda or turbo are just following the easy route, whether they make more power than us is pretty much irrelevant, it takes a strong person to say "nup, I may do things the hard way, but I feel better about it in the end".
That's why I struggle on with my humble SR20VE .

the K series will own the VE in every way shape and form and twice on sundays. The tranny holds boost, the motor holds boost the head flows better the valve timing is more advanced and it comes with a factory warrenteed big and small cam.
it also has better aftermarket because people are willing to spend 1K on a header and 1500 on IPS cams and 800 on Kpro and get 250whp out of 2L.
The only chance you have is hoping they didn't swap the motor into a hatch and you might have the weight advantage.
But don't count on coming out the winner all the time

so whatyou are saying basically is ........ we dont stand a chance ..... in all honesty i think a 20v is a better challenger, but only 400 made, makes it the least likely....... i am stil optimistic with all the tests being done... but i think k20 does have more advantages somewhat.
the K series motor is far more advanced and developed. I think after the testing that Mike K and I are doing, we will have more of a chance of being competitive.
If you really want to compete, you should sleeve, and stroke to atleast 2.3L and build it, should net mid to high 200's atleast.
I know for a fact that there far more advance in development.But what about if these engines where equal in specs.
SR20ve 2L
10:3:1 compression
Cams In High 264 10.7 Ex High 268 10.3
Makes 187 hp @ 7200 With N1 cams 215 whp @ 7800
K20 2L
11:5:1 compression
Cams I don't know but thay are bigger because K20A makes 220 @ 8000.
I will like to know K20 stock cam specs.They are probably the same or close duration as the N1 cams I think because they make peak hp at about the same range even tough I know there are other things in consideration on peak hp.My point in making these engines equal in specs is a Sr20ve with 11:5:1 compression(higher than stock)with N1 cams is kind of equal to the K20 and we make more whp @ 200 rpm less than the K20.Thats how I did alittle comparison and I think sr20ve are not that far behind in performance.The only thing that we still don't have some serious kick ass cams to improve performance over the N1 cams.

uh i doubt that.. this is bench racing... we are talking about why one motor is better than another...
so based on all that was said it boils down to a better rod ratio, cams, higher compression and head flow
headflow can be helped with some major headwork, p&p, valve jobs, posibly changing the quench zones.. i'm sure with tricks someone can get it to flow really close
the compression can be raised with the right pistons
cams, well thats the hardest part as our best choice of cams will put us at slightly higher numbers over their stock cams

^I was thinking that the reason that they make more whp from stock it's because they have way bigger cams and run higher compression.If the sr20ve from stock came with the same compression and about the same size cams we will be pretty close to what they put down.Then we will have a 2L making 230+ @ a higher rpm in stock form.

I doubt it.
The K20 head flows like crazy.
They flow about the same amount as a ported out VE head. And that's stock.
The K20s also have a higher tolerance before detonation, so they can get away with more before getting there.
The K20 is a sick motor, and will take quite a bit of development and work on the VE's end to catch up to just a stock'ish K20 motor. If the K20's modded, forget it.
The F20C found in the S2000s are sick too. Those heads are even better than K20 heads...
