Clio 172/182/197 engine
I have been thinking of an engine change over the winter, considered Duratech but from what I have read there appear to be plenty of complications,
and a lot are just 134bhp std. The sporty 2.0 Clio engines could be a better stating point, more power, and the are built to rev more than a std
Duratech. So has anyone fitted one to a 7 type car or looked into doing so ? Suspect gearbox will have to be fitted via a purpose built adaptor
plate, also std Clio inlet manifold will have to go - it curls over the top of the engine, might make engine too tall, so would replace with thottle
bodies or bike carbs.

All have VVC meaning complicated wiring/ecu etc, or removal- if removal then you loose a good chuck of the power.

A standard Duratec will make 145bhp out the box, and if you fit throttle bodies around 180bhp, and is very easy to get up to 200bhp.
There are many Duratec tuning parts available from various sources.
Not sure about complications, its a fairly straight forward install, only real issue is expense when compared to Zetec install.
I would imagine its much cheaper and easier than a Renault installation.
The main issue with Renaults is they complicate things just because they can. I should know I used to run a F1 Team R26 Megane.
Duratec Engine is fitted, MS2 Extra V3 is assembled and tested, engine running, car now built. IVA passed 26/02/2016

A friend of mine runs a 182 clio fitted with a 233bhp 197 engine and cost a lot to get to that compared with a duratec and had a few issues too with
it recently throwing a rod, may be a reason why not a first choice for a 7

I think it's a good idea I have driven the 182 Clio and think it's a fantastic engine but I did opt for a 225 megane at the time for my
wife's daily runner.
Some people will de-motivate you and try and talk you into going down the tried and tested route, nothing is impossible and would nice to see
something a little different

Here here! Anything is possible - just dont expect it to be easy, and you will have to solve all the issues yourself, and no one has done it before.
Do it!

I agree with the different route if you're clued up.

thanks for the replies, nice to see a range of opinions. I had assumed i would have to do a load of stuff to get it to work, but i do have a lathe and
milling machine etc, think the next step is to take some measurements from a mates 172 cup. Didnt know they had vvc, does anyone know the basic set
up, is it variable cam timing like BMW vanos, or an oil presure activated extra cam lobe like Honda vtec ??? I recal that the ST170 Duratech has vvc,
how is that dealt with in a 7 install ??

Honda VTEC, Toyota VVTLi, Nissan NeoVVL, and Mitsubishi MIVEC are the only engines that have changeable profiles on the camshafts.
BMW Valvetronic is not included here, but someone would get me if I didn't mention it!

there is an ecu controled solenoid on the top of the engine that feeds oil to a dephasing inlet cam pulley that contols the valve timing.

It's a simple cam dephaser as said, so almost any aftermarket ECU should be able to control it in an on/off mode, though I don't know if
that's how it's controlled by the original ECU.

Just to comment, i think doing something different is the way to go, and dont be put off by people saying its too much work. At the end of the day, it
will be more work if you cant just 'copy' what others have done, and help is going to be greatly reduced, but if your anything like me,
that just makes it more fun!
Think of the reward your going to get when you car is finished and its different to every thing else!
