transmission change

[jyh888]

sounds good, what is the fastest time an euro ever got at wakefield?

BTW regarding the transmission, if i can get a full DC5R gearbox with LSD, clutch kit including flywheel etc, should that be able to be transplanted into my euro? (keep in mind that my car is auto trans, i dont need to change ecu do i?)

because if i can, i will change the gearbox when the car gets older in its age when the gearbox dies and i can also do an engine rebuild at the same time.

Looking through Natsoft, I saw a high 1:16 before.
No, you cannot put a DC5R gearbox straight into your car as the mount is different. The case should be different too.

If you change from auto to manual, you will need a manual ECU.

can i change the mounts to fit? and will i need a dc5r ecu or cl9 manual ecu? can ecus be directly be swapped like that?

theres many k24/dc5r gearbox swaps into ek/eg civics, so i believe it shouldnt be too hard to do it in a euro aswell. I will be doing when the car gets older as i want to keep it and not sell it. I just want to kno the process and whether if it is possible or not. Thanks aaronng

Not sure if a company is selling mounts to use the k20 gearbox. You will need a CL9 manual ecu, matching immobiliser and matching transponder chip from inside the key.

It is not easy to replace it like in the EK and EG civics because of the tighter security and the fact that the Euro chassis is not popular for engine swaps.

ahhh ok sounds like a lot of work, but ill be the first to try a higher revving k24 combined with a dc5r gearbox in a euro would be amazingly awesome! I will do more research and find out more into this and let you guys know. Appreciate your help.

Ok guys ive done more research, and i was really interested in JDMyard's setup of the k24/dc5r gearbox. However, I was told that installing a dc5r gearbox in a cl9 is too much effort and not worth the cost and instead a CL7 (euro r) gearbox will be better.

JDMYard can source one for me for about $2.5k without flywheel/clutch etc. Now my question is since this is only the gearbox, what else do i need to complete the conversion. Can someone provide me a list of items i need.

Will i need to run a CL7 ecu or can i use a CL9 manual ecu? thanks

my budget for this is 4-5k, do you think this is do-able? it does not need to be done straight away nor am i in a rush, just want to collect information so i can start preparing and collecting these items for future build. thanks guys, please provide me your opinions

So when are we all going to have an Euro trackday?

You do that! I'll bring the Aurion...

[oongie]

Logically I think you would need a CL9 ecu, as the CL7 is a K20 and the CL9 a K24.
Correct me if i'm wrong knowledgable ones.

thats a good thought - but the ECU is mostly relevant to the engine not the gearbox.

Like older cars doing a auto-manual conversion , you can use a manual ECU of the same model. And do some rewiring to configure the reverse signal sender , Park and neutral selection etc.

but for such a new car , i would strongly not recommend such a mod. It wont bring your 1/4 down or wakefield times down if at all. And the resale will be reduced too.
All for the price of possibly $3-5k all parts n labour at a workshop. Not worth it.

Just stay with your decision and drive auto and get as good as you can or sell it and get a manual car.

thanks for your input. I dont plan on selling this car at all, i will keep it for all my life lol. Why wouldnt it bring my 1/4 mile or wakefield times down? a 6 speed close ratio gearbox should be faster and also the lsd will give me better control on the track wont it? The car is still relatively new so i am not doing it straight away, i will most likely wait till the car is older but i am just researching into which parts i may need for the conversion.

Also if i do buy a manual euro, how do i change the gear ratios without replacing the whole box? i was thinking even if i do buy a manual i would need to buy a light flywheel/ HD clutch, LSD etc and all up + labour would still cost me at least $3k...

[bennjamin]

i stated "....wont....if at all". My point is for the effort you wont get such a bang for buck result. The Euro is a heavy fwd and the difference between an auto and modded manual isnt much over the 1/4 or at wakie. IMO stick with what you have or sell up and get something else

[oongie]

How about lightening the car up a bit as well...
if its a long term project as you've stated.

K20 / K24 frankenstein, is the go IMO,
But to do it properly its going to cost big $$,
You'll only end up using the block of the K24 for the displacement.
The other parts would be K20 parts.
