Haha that's mint so you would say it's worth doing then for the fun I'll get out of the car
Honestly it's a really hard shout, if the cars up to spec and in a healthy position to be boosted, and you can potentially do it cheaply, absolutely. Even though its only 230 bhp which isnt really considered huge power in todays age at all, theres not many things that can keep up with a boosted Clio around b-roads. And yes, its mega fun.
On the other hand like i said, if it was a high mileage not looked after, gearbox about to go etc it could definitely not be worth doing, imagine having about 100 miles of fun after you've just dropped thousands on the conversion and then you need to start swapping gearboxes etc
Have you ever owned a clio before? do you know your way around them? thats something i consider an important part of boosted Clio ownership, i would say they need a much closer eye on them, dont get me wrong 230/230 is not a HUGE stress to an f4r at all, its quite a reliable power level to be at, and theres plenty of low boost clios that get absolutely abused at track.
I would recommend either buying an already boosted clio, or if you do go down the route of boosting it yourself do a compression and leakage test before hand to see how much wear is on the engine , see how the gearbox feels etc, you could give it to ED and get them to do this and then let you know where to go from there.
