hey guys
im thinking about doing a k20 conversion for my dc2
i was just wondering what exactly is involved in doing the conversion in regards to parts that i need.
Parts that im 100% sure ill need are:
K20Z
gearbox
driveshafts
wiring loom
ecu
hasport mounting kit
shift linkages
Im sure there are a few things ive missed so can you guys enlighten me as i need to get the conversion under was ASAP
Thanks
Joe

Isn't a k20 conversion very expensive?? Why not opt for a k24 conversion from an accord euro

i think the cheapest k conversion with good gains would be from a k24 + dc5s or standard dc5 gearbox.
a jdm/audm k20a type r would be approx 9k for motor complete + 7k in parts and labour.
around there..
so 16k for a complete dc5r swap into your eg/ek/dc

damn 9k for a complete motor? just buy a statutory write-off accord euro. If your paitent one will come up and you should be able to snatch it up for 2-4k. then you could sell whats left over to regain some of your money.

K24s are abundant and easy to source either from crv or accord euro.
2nd hand engine shouldn't cost no more than $2-3k

Im sure ive seen complete JDM K20 packages for around $7 grand... importing/buying a half cut/wreck will certainly save u a few bucks.

I've seen a JDM DC5 K20 half cut for $7K
And then individual engines for between $3-$4K
Look at Hybrid Racing, they are an American company that specialises in K swaps

That list is for an EG, you will need to change some items to suit other makes of cars.
OR you can quote properly from other websites.

why you still got a b20 if theres a k24 for 1k ?
damn 9k for a complete motor? just buy a statutory write-off accord euro. If your paitent one will come up and you should be able to snatch it up for 2-4k. then you could sell whats left over to regain some of your money.
accord euro is 4.5k stat write off.
only thing you can use is the motor and the loom and still with the loom you have to make modifications to it

Im considering K series for my Delsol we see how we go

dont forget the k20 box alone is 2.5k so that bumps it up to 3.5-4k ....
but yea k20a packages are getting cheaper and cheaper.. you can definately pick one up for 6k soon .
Benson
22-08-2010, 10:43 PM
If you used the K20z wiring loom and gearbox, you'll need it to be re-pin and modified. The gearbox runs a electric speed pick-up sensor. You'll need a speed convector to convert the right signal to the ECU
Other than that, you'll need the basic Kswap conversion bits. - Mounts, Kpro, Kswap headers, Conversion harness, Kswap shafts
If you need any K-swap, shoot me a PM, i might have a few things lying around

Item One
For Sale: K24 Engine, Five Speed Triptronic Automatic and everything attached to it.
Conditions: Excellent! Still runs very well. 100,000KM's on the clock.
Price: $8000 ONO.
Pictures: On request. But it looks like every other stock standard K-Series.
Not just the engine mate.

Below you will find information related to the K series engine swap.
K24a1-Honda CRV comes in with 9.6:1 compression and 2.4 liters of displacement. The motor is rated at 160hp at 6000rpm and 162 at 3600 rpm. This motor does not use the conventional VTEC mechanism from the earlier B series motors but does have VTC. Instead it only has 2 cam lobes on the intake side and 1 on the exhaust lob. This motor has no VTEC mechanism on the exhaust cam and runs on 12 valves before 2200rpm. It also has smaller ports than the Type S and Type R. The motor also comes with a 5 speed transmission instead of the 6 speed and has no LSD.
K24a2- The Acura TSX comes in with 10.5:1 compression and 2.4 liters of displacement. The motor is rated at 200hp at 6800rpm and 166lbs-ft at 4500rpm. This motor uses the conventional VTEC mechanism as the older B series motors but with the addition of VTC. This motor uses a drive by wire throttle and has EGR castings on the manifold. This motor comes with a 6 speed transmission and no LSD.
K24a4- the Honda Element and Accord come in with 9.7:1 compression and 2.4 liters of displacement. The motor is rated at 160hp at 5500rpm and 161lbs-ft at 4500rpm. This motor does not use the conventional VTEC mechanism from the earlier B series motors but does have VTC. Instead it only has 2 cam lobes on the intake side and 1 on the exhaust lob. This motor has no Vtec mechanism on the exhaust cam and runs on 12 valves before 2200rpm. It also has smaller ports than the Type S and Type R. The motor also comes with a 5 speed transmission instead of the 6 speed and has no LSD.
What K do I want?<BR
K20a-JDM ITR and CTR both come in with 11.5:1 compression and 2 liters of displacement. The Type R motor is rated at 220hp at 8,000rpm and 152lb-ft at 7,000 rpm. The CTR is rated at 200hp and 144lb-ft. Both of these motors have the same VTEC mechanism as the older B series motors but with the addition of VTC. It also has Larger cams, higher compression and larger intake manifold than the Type S motor. This motor comes with a 6 speed transmission and LSD. The 6-speed manual transmission uses multiple synchronizing cones for all gears, including a triple-cone synchronizer in 1st and 2nd gears and a double-cone synchronizer in 3rd through 6th gears.
K20a2-Acura Rsx Type S has 11.0:1 compression and 2 liters of displacement. The Type S is rated at 200hp at 7,400 and 142 lb-ft at 6,000 rpm. This motor also comes with a 6 speed transmission with no LSD. It has the same VTEC mechanism as the older B series motors but with the addition of VTC.
K20a3-Acura Rsx Base and Civic SI models come in with 9.8:1 compression and 2 liters of displacement. The Base motor is rated at 160hp at 6500rpm and 141lb-ft at 4000 rpm. This motor does not use the conventional VTEC mechanism from the earlier B series motors but does have VTC. Instead it only has 2 cam lobes on the intake side and 1 on the exhaust lob. This motor has no VTEC mechanism on the exhaust cam and runs on 12 valves before 2200rpm. It also has smaller ports than the Type S and Type R. The motor also comes with a 5 speed transmission instead of the 6 speed and has no LSD.

The motor also comes with a 5 speed transmission instead of the 6 speed and has no LSD.
What is I-VTEC? VTC?<BR
The "intelligentî I-VTEC system uses Variable Timing Control (VTC) to adjust "camshaft phasing." By varying oil pressure, VTC can continuously vary intake timing relative to the engine's exhaust timing. The result of I-VTEC is improved response and enhanced performance at low engine speeds and efficiency across a broad power band. This has been coined Hondas gift to tuners. From the factory VTC has not been optimized for pure performance. In the future look for the K series motors with the most power to be optimizing the VTC system.
What ECU will I have to use with my K series swap? <BR
Honda has installed its latest version of the immobilizer into its newer generations. This limits us on how to bypass this system. Luckily Honda of Japan gets an ECU that does not have the Type 3 immobilizer installed. Thus you can install a Type R ECU into your EG to allow it to crank with the necessary wiring. The other method requires the use of a Hondata K-pro. The K-pro has the ability to disable the immobilizer from within. In addition to allowing you to disable the immobilizer you will be able to adjust timing, fuel and crank angles. If you plan on going fast with you K motor than the K-pro should be your first purchase. For more information regarding the K-pro check out Hondataís website in addition to the Hondata notes found on hybrid-racing.com.
How will I shift the car? <BR
You will need to use the stock shifter box in the RSX. Then you will need to run the cables into the chassis and connect them to this unit.
Can you keep AC and PS? <BR
You will be able to keep AC with custom lines and condenser mounting. The PS will also work with custom lines and a custom hood.
I know that the EG has a return fuel system and the RSX has a return less system what do I do about the fuel system?<BR
You will need new fuel lines, new fuel rail and a new fuel regulator. This is due to the fact that the RSX motor has a return less fuel system and the EG/DC/EK chassis have a return fuel system. The Rsx does not have a Regulator on the fuel rail like the older style B, H, and D series motors.
Are there any clearance issues with the K series motor?<BR
The hood on your EG/DC/EK will fit with no modifications. We have tested the Invader style carbon fiber hoods and have not had fitment problems with these either.
On the DC/EG/EK chassis with power steering some lines will have to be rerouted and/or removed.
