Clio HOW TO - Megane 225/230/250 Engine Into Clio 197/200

[Big Steve - Raider]

Can one of you knowledgeable chaps help me understand what is needed to fit a Megane 225/230/250 Engine into a Clio 197/200??

Specific questions I have are:

• Engine Mounts - Is it bolt in with Clio/Megane mounts, or do you need to make custom mounts
• Exhaust Downpipe - Custom or is someone making them?
• Gearbox - Megane or Clio?
• Driveshafts - Megane or Clio?
• Clutch - Single Mass Flywheel
• ECU - Total Standalone or adaptable to OE ECU from Megane/Clio with new loom?
• Connection to the Clio Control systems (Speedo, Dash Etc..?)
• Intercooler - Custom or is someone making them?
• Radiator - Megane or Clio?
• Intercooler Hardpiping - Custom or is someone making them?
• Insurance - How are you getting on Insuring the car after conversion?
• Cooling Pipework

I'm sure those of you who have already done this have the answers to my questions @stephenvenning @tutuur @DannyAG200

Thanks for your help

Use the meg ecu and wiring spliced into the clio loom.
A quick search on google reveals some good info Megane 225/230 Engine Conversion into clio

I would use the megane gearbox too as the 197/200 box is notoriously weak. R26 gearbox with diff.

Gents sorry to bump on this but if you are looking. I have a 51k 250 engine with all ancilliary's inc turbo along with cup gearbox driveshafts and full wiring with ECU mapped by RS Tuning and 250 fuel pump.
Cheers

I will soon have a spare 1.8 20vt lump spare

If it needs custom mounts and wiring I would just go tfsi route have plenty of info to help you for free or the straight forward 20vt but you have had that before

• Engine Mounts - Bolt in
• Exhaust Downpipe - Link pipe from Megane connects nearly direct to the Clio system, only need to weld over the flange/cut the mid silencer out.
• Gearbox - Megane imo
• Driveshafts - Depends on gearbox used
• Clutch - Single Mass Flywheel + dci clutch or just standard 197/225 again dependingon gearbox
• ECU - OE R26/ph.2 ECU from Megane, looms need to be adapted.
• Connection to the Clio Control systems (Speedo, Dash Etc..?) -yes
• Intercooler - When fitting the Megane rad the intercooler will fit too
• Radiator - Megane imo, clio's is too small. You'll loose a/c though
• Intercooler Hardpiping - Standard 225/forge etc.
• Insurance - How are you getting on Insuring the car after conversion? Not, but that's because it's not possible over here
• Cooling Pipework - custom

I shall be doing a full step by step guide to doing this conversion. Even the smallest of things so bare with me
Everything is going to be done in my garage except the ecu immobiliser

Well I've completed my wiring loom now, just using some of Renaults special cloth tape to wrap my loom up so it looked factory, like I said il be doing everything except the ecu coding, but I can't really say much until my build is completed, or atleast running.
I plan to have it running on the road mid August, as much as I hate giving deadlines to myself especially on something like this.

Look forward to hopefully shedding some more up to date info on building these cars

Did you ever do the conversion guide?

quite a few guides knocking around but when people tell you the 250 box 100% doesn't fit in the 197/200 bay it does

Need hammer modification?
I assume thats the PK box mated to the 197/200 engine and not the f4r 774?

yup on a 200 but would still fit the same on a turbo motor in the bay.

Only need some wiring questions answering really, the rest I have sorted I think.
