k20a in a dc2r

[BiGANG]

hey guys, i was looking on here recently and in us forums and have noticed a popular mod is the k20 conversion now. i know someone here has done it hrv.boy i think it was. I was hoping to find out what was involved in such a conversion for example would all the front suspension have to be changed, custom shafts? Also how much heavier is the k20 than the b18 because it looks physically heaps bigger, would this kill the handling of the teg as well. I probably will never do this mod but i am curous to find out what is involved.

Anyone with the conversion done (hrv.boy, ppl involved in egk20a) your input would be really useful.

[Jomsy]

hasport sell engine mount and drive shaft kits for k20 into dc2, so its "almost" a bolt in job

[lerroy]

Ok just to get things straight HRV-BOY/pascoe hasnt done it...

im sure EG5 would give you some more info :P

[kenji]

from what i know the k20 is lighter than the B series engine ....

[Chi]

ROFL @ HRV 80Y k20a conversion. *wipes tear*

k20a is lighter than B18CR

[EGB16A]

from what i know the k20 is lighter than the B series engine ....

from memory it wasn't by much, about 5-10Kg

[Q_ball]

i always though pascoe did....damn huh....
k20a a better engine than the b18c??

[spoondc2]

More potentials i think....
When you need crazy powers, you will need a K20 instead of working on B series engines. Maybe i should forget about the B series ay


Personal opinion...

[BlitZ]

k20 pretty much kanes all bseries hands down... cost alot more though..

every which way.. k20 repsonds better with mods and its lighter... the b series has been around since like 1990 though.. so eveyrhting is tried and done.. the k20 is still a baby.......

from what ive read...
k20 with hondata kseries would net 140kw atw (dont know how reliable the dyno is) ... regardless, its still crazy figures for an almost stock engine

[ITRBoI]

k20 has more potentials in power.... HRV 80Y from memory he doesnt have one......best to talk to badhbt.....he's doing his one at the moment.......give him a pm

[BiGANG]

k20a a better engine than the b18c??

in standard form i think the k20 and the b18 are on pretty much on par but the k20 is heaps more responsive to mods. Just look at egk20a. Hasnt got much too much done and its making 230-240hp from a jap spec jap spec K20a

If i had 10g(and probably then some) to throw at my car i would love to try it.

[faijai]

i agree with blitz
the k20a responds a hell of a lot better with mods then the b series engines do.

i always thought the k series were heavier? guess ya lern sumfign new eveyr day

[BlitZ]

If i had 10g(and probably then some) to throw at my car i would love to try it.

hahaahahh if i gave you 10k.. i reckon u would buy a dc5 instead heehehh

[SiR JDM]

Theres a k20 in a dc2 here in melb... jdm front conversion too. Its finished up and running and working but not %100 yet ready to be tested ill let you know how it goes drag/dyno/track when he does.

[BiGANG]

hahaahahh if i gave you 10k.. i reckon u would buy a dc5 instead heehehh

nah, i am pretty sentimental. I would rather my dc2 over a dc5, just like how ppl spend big $$$ on turbo conversions and engine work, if they put their cash aside for a year or so they could get a faster car standard, but sometimes you feel bad letting em go.

I didnt want to sell my crx, put it in the paper ppl offered money. im like nah, he will thrash your ass. then i would suddenly be not negotiable. So in the end i gave it to my little brother so i can at least it perfect like i had it..

Im a bit wierd like that

[Tony]

Someone in the states has officially weighted both the K20A engine and B18C engine with gearboxes. The K20A engine is about 10kg heavier.

The K20A engine sits lower than the B18C in a DC chassis, by about an inch, the hood should clear with no problems.

[HRV-80Y]

WTF !

omg who ever start dat i had a k20 shld die !

if i hav a k20 den damn i got jipped hard coz my car runz like a vtir...coz its a vtir !

[fried]

lol ur just pissed off its slow for a k20.

[J-MuN]

PM egcarbz. He can give you some info on the K20A DC2 in VIC.

[Perry]

pretty much if u got a half cut from the dc5R or EP3 u will need to change
Engine mounts (Hasport)
Relocate your radiator (by memory)
Custom intake pipe for airfilter
obviously brakes need to be upgraded
exhaust system needs to be custom for the b-pipe section i think (due to the K series engine are mounted backwards compare to b series, so headers length will be different

correct me if im wrong with these stuff

Don't need to relocate radiator for DC2. DC5R and EP3 header won't fit DC/EG/EK, you'll need to use the Accord Euro header or TSX header.

[JRC]

Nah k series is lighter only problem people seem to find with these conversions is the height factor of the engine, but im pretty sure hasport conversion kits are available with headers to suit a dc2....

[00dc2]

i find it hard to believe the 10yr older engine is lighter.. even if it is 200cc smaller..

[NTR16N]

How bout for us LS boys?? same as DC2??

[Paul1985]

to drop a K20a in you will need:
-engine and tranny including: engine harness, charging harness, shifter cables, linkage clips/cotter pins
-Conversion Harness (Hasport, Hybrid-Racing)
-ECU (can use stock JDM DC5 ECU or hondata, AEM)
-updated suspension and chassis gear
-updated brakes
-engine mounts (hasport/hybrid-racing/avid and theres a few others)
-shifter box
-depending on the radiator, you may need a new one and it needs to be relocated, if so new hoses aswell
-coolant temp sensor & fan switch (im pretty sure u use the ones off your old engine)
-new fan
-clutch line
-updated fuel system including new: FPR, fuel lines, fuel rail and a fuel pump
-throttle cable (can use the stock one off the old engine most likely)
-axles (DSS, hasport, hybrid-racing etc or you can now make up custom OEM ones mixing DC5 with B-series axles)
-custom intake and exhaust
-headers (SSR, DC Sports, Hasport + others or custom)
-tuning

dont forget the new 6-speed shift knob if getting to 6-speed to! lol

there the main things, there are also parts out to make the swap more of an ease that id get i.e karcepts shifter relocation kit.

to do this IMO it would cost around $15-20k (inc. parts + engine, maybe a tad more if you dont have brakes and sussy updated) It could cost heaps more though, depending on what parts you use, whether new or used, etc. There is just so many different parts you can choose and different routes about this swap that it is hard to put a figure on what it would cost exactly. This is without labour aswell. You will most likely need to purchase a few new tools and fluids along the way if DIY.

It isnt as hard a swap nowadays with all the info out there and all the parts made up for the swap also. If anyone is considering doing this swap, contact Yonas (EG5). They can help :) Great guys from JDMYard.

[nipnip]

k20 is an all alloy engine = lightness

[Paul1985]

btw BiGANG.
If your after more info, visit www.k20a.org they have all the info you will ever need regarding this engine :D

Hope my post helped a little.

[BiGANG]

i dont think going to the extent of changing fuel lines would be necessary, Heaps of high power hondas run standard fuel lines and have heaps more power than the 162kw the jap spec ITR motor has. Also depending on the car, things like brakes might not be looked at as seriously, ie on a dc2r all that would be required IMO are some slotted rotors and some good pads. maybe some braided lines. if you were doing the transplant on a gsi civic different story. But DAMN 15-20K is pretty expensive man. Makes you think if its really worth it.

whats a JDM DC5R front cut worth here with brakes, ecu and the ignition barrel with key so you have to disable the immobiliser worth?

if you change the hubs i dont see why you cant use the whole dc5 front end brakes and all. would save on custom shafts plus there is your brake upgrade done to pretty red brembos. considering it was said before the shafts are pretty much dc5 items with the b series combo jobs. that would mean the dc5 items are long enough.


ps. ive discovered the k20a.org site last night. was reading everything i could. Still going its a mad site for k20 info.

[jimmeh]

you can buy a k series conversion kit from hybrid with everything you need. +/- 2500US

JDM DC5R front cut is around $8k to $10k, not including panels, rims and lights. You don't need the ignition barrel/key to bypass immobiliser on JDM ECU, simply ground the fuel pump relay wire.

[Paul1985]

you can use stock fuel lines if you like, but im sure there must be a reason why its uncommon for people to do so?

same with the conversion harness, you could do it yourself, but u will end up with one massive headache!!

And if the swaps going into a teg, the brakes are pretty decent as you mentioned.. it all depends on what car its going into.

All you will need to be able to disable the immobilizer is the JDM ECU or an aftermarket one, just as Tony mentioned. Did the JDM DC5's come with this Immobilizer? I read that they didnt somewhere, and thats why we would need at least the JDM ECU if your using an K20 that isnt Jap spec..

I dont know about the whole DC5 front end brakes and all being swapped over. The problem is that the DC5 is 36mm, but u did mention changing it all over so this would work. I dont know if it is relevent or not, but the 98+ JDM DC2R Brakes come with the same 36mm that the DC5 did, doing a 98+ 5-lug JDM DC2R Brake upgrade on an EG allows you to use the stock DC5 axles. So it may be possible to do what you asked, im not too sure....

[BiGANG]

from what i read, the jdm k20 has an immpbiliser but its easily bypassed, instructions are on k20a.org somewhere i stumbled onto them the night before last.

You were saying paul that if you have the 5 lug 98+ ITR hubs you can use the dc5 hubs. Does that mean if the k20 is going into my car i wont need to modify or purchase shafts to suit?

Are the hubs interchangable anyway between dc2 and dc5? I would imagine lower control arm might have to be changed at least for it to work but noone really does it. if it were easy it would have been done to death in the US already so im guessing it would be a pain in the ass.

im still curious as to why they change the fuel lines though. Are tehy usually swapped for biigger lines or same diameter just new items?

Yes you are correct, IF YOU ARE USING HASPORT K SERIES MOUNT, the AUDM Type R axles will work in a DC2 type R, no aftermarket part is required. The JDM Type R axles won't work, they are slightly longer.

You don't need aftermarket fuel lines for this swap. All you need is a FRP. If you want to use bigger injectors, IPS or comptech can modify your stock 330cc injectors to flow 520cc for US$100.

Are you sure?? So the stock DC2 axles will work with this setup, no need for k-series parts at all??

[Tony]

No I mean the AUDM DC5 Type R axles. not DC2 Type R

[EG5]

few things to add

-DC5 front hubs will not fit dc2/eg/ek without massive custom fabrication (macpherson vs double wishbone)

-you change the fuel lines because of the fuel rail relocation and older model hondas have different fuel system compare to the dc5

-all dc5 axles will work on dc/eg with hasports mounts

-only jdm 98spec dc2R front hubs (36mm same as dc5R) will take 36mm stock dc5R axles without modifications

-audm dc2 type r front hubs=32mm

check out marcs k20a in his BADHBT integra, its CRAZY, he had the prelude type S h22a in there, now he has a k20a and its a fukn rocket boyz

[Banana]

why does everyone want a k20? if i had money to blow, id personally get the k24, then slap a JDM k20 head on it, rebuld internals and vualla ul have urself a 2.4ltr type-R engine, lolz.
u'd slap anyone with a k20.
Just a suggestion coz no one in aus has done it yet.

I think most people swapping in K20A's would love to do a frank aswell. Its more difficult both to source parts and to build. You would need to know what your doing with it as taking it to a mechanic certainly would add an even bigger sum of $$$ to the already expensive swap.

If i had cash to blow and was capable of doing a k20/24 frank, id do it for sure, no questions asked :D

It would be an absolute beast for sure! I wouldnt be surprised banana.. i think a few of these will pop up sooner or later :)

[NTR16N]

no ones answered as yet.. but would the k20 or 24 fit in an LS / DA9?

and is our set up the same as DC2 and DC4 engine bays..

[egcarbz]

my 2 cents are.. k20 is like fully SiCk but fully alotta work and fully costs heaps!

im yet to come across anyone who has done a K swap on a DA9 and ive been doing alot of K research. It would be possible, you would need to get all custom parts whereas with EG/EK/DC you can purchase alot of the parts pre-fabbed now from companys such as hasport, hybrid-racing etc. Hope this helps a little :)

i think doing putting a k20 head on a k24 motor would be similar to putting the b16 head on the b20 with the results probably similar (hear me out here) Im sure it will be done and has been done plenty of times in america, but wouldnt you think of the pros and cons of the setup

pros.

probably a shitload more torque
bigger engine capacity (obviously)

cons.

inability to rev high like the k20 due to high piston speed (bore and stroke not square)
probably more volatile due to this factor (some would argue against this but its more likely than with the k20 anyway)
very expensive to do IMO on top of the original conversion from say a d or b series in an older honda.

Now. ppl add pros and cons where you think necessary but i think with the k24 the cons do outweigh the pros pretty heavily.

proof of the volatility of a heavily tuned 2.4 motor is the fact that most ppl with hardcoore setups get different crank etc to bring the capacity down to 2.2L This would help the rod/stroke (i think thats what its called cant remember now) but it still wouldnt be as good as the K20.

IMO, i would get a k20 and with the cash i would have done a worked k24 conversion work the absolute shit out of a k20 and 'voila a hell of a fast car'

ive done the research and come up with nothing too..
but with measurements and bolts ons.. most dc2/4 stuff are straight replacements for DA9 parts anyway... B Series stuff etc..
guess ill do more research...

lol...bloody clown :P
