K20a Q&a

It's not a problem to endorse. I'm using eg6 convert k20a from dc5r. Using the mounting kit from hasport. It fits really nice in your engine bay. Very few modification. The only thing to modify are air cond piping. Since the pipe size from k engine are different. U need to make adapter for that. It's just a small job for machine shop.
About power, in stock plus you modded the intake and exhaust. I said it's better than any b series.
But the problem will always to find traction. The good tire size should be 16 with 225 wide.
Anyway, happy modding.

B-series is now easy, but since now EG halfcut is more expensive than manual trans 5 speed K20A3, it's a good mod to make.
Maybe can mod a 2door EG that way.
Wiring I already understand.
Mounting wise, I heard there are copies, but haven't seen yet. Who's selling them?
Axle/driveshaft wise, who's doing the modding?
Where to get the EP3 parts to retain A/C? (are the even copies out now?)
Oh, forgot, and the header needs to be bought/custom made too.
Just hope everything's cheaper than a straightforward B16A swap.

Agreed. Exhaust need to be custom. But if you're looking at dc5 type s spec it stated that it has 200ps. Not 160ps. And vtec on both exhaust and intake side. In us they note it as k20a2. Same as ep3 engine.
Now k-swap parts can easily can get in malaysia i just have some experience with 2 eg k-swap and my self ek k-swap no serious mod job just some time taken for wiring tuck and aircond hose&power steering hose mod so the engine bay will look more nicer
Nice job this eg. Anyway Loo. Have you sorted out the hondata launch control yet? I want to tune my K-pro again. It's look like out of tune. Anyone know anyone who familiar with to tune K-Pro? Heard JC racing sell this k-pro now. But who tune it..
yeah i did some tune with my customer DC5 with k-pro and my self as well its simply as 1-2-3 but need some time to get proper launch rpm so can make some full throttle,speed,and ignition retard to get 0-100kmh fastest time if your eg installed k-pro with everything stock you might get 210-215 whp with a little upgrade intake manifold should go to 225-230 whp
TS, how much u got quoted for the DC5 type S K20A?
Izzit the one with 6 speed tranny and 200ps?
Here is a good write up on K20A2 and K20A3.. just wanna share share...^^
BTW sifus, can a DC5 dash fit into an EG/EK?
The dash looks very nice le.... cant stop drooling looking at it....
This is the one in RSX type S
"With the new K-seires motors around us, there is a need for new information about the motors themselves. This article won't deal with swapping it in any car- but rather comparing the two variants.
the k20a3 is found in the 02+ civic si and the base model rsx and have a 5 speed tranny.
the k20a2 is found in the rsx type S and comes with the 6 speed tranny.
The k20a2 and the k20a3 share the same 2.0-liters of displacement, bore/stroke, block, head, valves, and intake manifold. However, pretty much the entire internals and external bolt ons couldn't be more different.
The k20a2 has higher compression pistons, more agressive cams, dual valve springs, and a tri-Y header with larger primaries than the k20a3. If that wasn't enough, the K20a2 has a completely different - and more advanced - method of iVTEC than the a3.
On both motors, i-VTEC really consists of two features: VTC (Variable valve Timing Control) and VTEC (Valve Timing and lift Electronically Controlled).
VTC, in both cases, is simply a hydraulically controlled adjustable cam sprocket that varies intake cam timing on the fly depending on engine speed and load. VTC does not affect the exhaust cam.
However, It's the VTEC portion of these systems that differs.
On the K20A2, VTEC is old school. Like a B-series, the cam has 2 profiles on 1 shaft. At about 6000 rpm, the middle rocker stops resting on the lost motion assembly, and picks up to follow the large lobe. Nothing new.
On the other hand, the K20A3 uses a completely different method, but is still called VTEC. At low rpm, the two intake valves operate with different cam lobes. One valve gets the primary lobe (the taller lobe) and the other gets the secondary lobe (shorter). The exhaust valves always get shoved open by a single lobe with no tricks at all. When VTEC kicks in at 2300 rpm, both valves start following the primary lobe. That's it. There's no 5500 rpm kick in the seat.
Other than this use of a shorter valve at low rpm, its much like a SOHC VTEC D16Z6: VTEC only on the intake side. But even then, can you really call <that> VTEC?
All of that is enough for the A2 to boast a 40 horsepower and nearly 20 ft-lbs of torque advantage over the A3."

That's what i want to hear. Maybe i'll sent my car to you in the near time. I want to sorted out those idle and retune my K-pro. Anyway loo, what piston you recommend to me last time? I want to refresh my engine with high comp piston and beam conrod. What's your recommendation loo?

dc loo n nates gtr.
if take dc5r engine into eg or ek, besides hasport mount+custom exhaust (due to cross member clearance) +custom radiator (if needed) +new fuel rail (due to non return fuel system)... what else do you need?
can use dc5r brembos? with abs sensor n all?
how about drive shaft.. must custom?
can put in dc5r meter? need to use the whole of dc5r wiring?
thanx for answering my queries.... just wanna find some info n knowledge only.
