Can anyone give some rough figures for putting a K20 into a civic EK using second hand parts where possible and doing all the work myself

Engine and box would have to be healthy, not high miles and ready to drop in

Ideally standard ECU to keep costs low unless aftermarket is a huge improvement for a basic build

Figures for a basic build? 230hp at the crank realistic?

Much difference between the K20A2 and K20Z4 when it comes to wiring etc... And are the gearboxes the same?

And if anyone could give a list or a link to everything thats needed thatd be helpful

:nice:
 
We quoted a customer around £5000 supply and fit for a kswap in an ek end of last year.

This is would be a basic kswap with a kpro.
of course if u wanted an aftermarket throttle body, intake, cams, injectors. Proper setup exhaust, or anything branded, that will all add up on top.

I need to reevaluate the cost this side of brexit But i may assume another £1k max.

How much of that is labour because id have no labour fees. Im needing to know a rough cost for the parts and im not 100% sure whats essential and whats not because ive never done a k swap

between £500 and £1000.

Just when your kswapping look around and dont buy things as soon as you see it. An eg/mb subframe is not worth £250 like these breakers are selling for. we found them for £50 complete . or u can buy an mb for £300. break the whole car and keep rear disc for your car which are 4x100 and keep subframe.
 
ive got a EG subframe and also got a MB2 as a daily driver, i measured the rear hubs on the MB and they seem to stick out more compared to a EG, know anything about this?

And when using a EG subframe in a EK what power steering lines do you use? I dont think the low pressure line is bent correct for the EK chassis, and the high pressure line has the small OBD1 connector where it sits inside the pump

With the subframes make sure u have the spacer braket aswell that goes on them aswell. Eg and dc2 have them normally. MB/MC Dont have them from factory.

Rear hubs are the same as ek and eg aslong as 4x100. We been putting these on loads of cars already.

Power steering lines you have to do custom

I run dc5 or accord pump.
Hybrid racing fitting that goes onto the pump. Then i use an6 ptfe line and fittings for the hight pressure then use a random hose with the correct inner diameter as the return. Use an ek or dc5 powersteering bottle.


Key thing to do is research before spending bucks on things you dont need.

EG manual rack must be the default?
Dont need to unless you want to be permanently non power steering the correct way
 
yeah got the spacers, its from a EG.

So neither of the steering lines from a EG can be used on a EK K swap?

The rear arms are a bit different on a MB, the bit where the top camber arm goes is different and i compared it to my EG and think it was about 10mm wider each side so itd be a total of 20mm wider for the pair

I measured it after people saying their MB6 4x114 swap had wider hubs and this is what makes me think if you're swapping the rears from a MB then you definitley need the fronts too as im guessing they're also going to be wider than a EK / EG

U just use the trailing arms. Not the lower control arms as mbs dont fit ek. mb lower control arms dont fit ek at all.

The upper arm(camber arms) are the same on all ef, ek, eg mb dc. (I have already searched this at work as i work at honda.

U just change the fittings for the power steering as the lines are all mounted differently. U have to make custom lines as it all goes a different way.

Mb6 and mc2 used 4x114 hubs with 262 or 260 (not sure what one)

and other mb or mc that had rear disc were all 4x100 240 or 260(again i dont remember which)

Honda literally use the same parts on all thier cars in that era just changing few bits here and there.
Iv literally searched all the part numbers so i kno.
 
Yeah im not talking about the lower control arm, the rear trailing arms are slightly different on a MB, ive got a EJ9, EG6 and a MB2 so i can compare and measure things when i want

Good to know about the lines, means i can sell them now

Few mates have the mb rear trailing arms on their cars And theres no difference ef,ek,egs
We have also fitted them to customers car and been nothing wrong in fitment at all.

there's so many people with both mb 240 rear hubs on their cars aswell as mb6 4x114 hubs on their cars.

unless ur measurements are out slightly.

we even converted the mb hubs to make them awd hubs.
 
Pretty sure I have an EK4 trailing arm on one side of mine and an MB one on the other.
There are design differences but no obvioius size difference (other than the stub axle is a different bloody size!)
 
I'll get some pictures one day

in what way is the size different?
 
Its a different diameter and needs a different wheel bearing.

One is 28mm with a 134mm hub wheel mounting flange. The other is a 1-2mm different and a 136mm flange. (I think they made the flange different to make it easier to figure out which you have)
 
If you need kswap bits then i have everything

Brand new Hasport EKK2 mounts
Nearly new Innovative EKK2 mounts here also

Kswap shifter an cables

Kswap loom

kswap Mishimoto rad

kswap hoses

kpro ecu

kswap manifold

i have load of bits here
