ITB's are easier to fit.
Both are likely to be quite challenging for a beginner, the cams will require you to do a cambelt for example, have you done one of those before on a 172? Its not rocket science but is quite involved. You'll need the ECU remapping afterwards too.
The ITBs are mechanically pretty simple, but require you to wire in a new ecu (unless you are going to try it russ16v style on the standard one?) which requires a certain amount of knowledge, and then that new ecu will need to be mapped of course.
If you want something that gives good gains and you can do yourself, and also is reversible later on if you want to go onto a different car, the RS2 is worth a consideration, although will still need a remap.
Because the clio is a speed-density based ECU setup, any significant change will require a remap.
have you ever done something like this before??
Do you know the cost of itbs as a material?
what is expected gain from rs2? i already have matched inlets
i havent. my friend who does all my work has been doing mechanics for over 5 years.
RS2, if you look in the stone automotive section it has some details including some example power graphs, about 15-20bhp is typical though.
IIRC its about 1200 quid in parts, and 250 or so for the remap, and then fitting is a few hundred but you wont need to pay that by the sounds of it.
ITB's you are looking at 2K or so for parts including a new ECU, then you'll need to map it on top of that of course.
He'll find cams a doddle then TBH
what price is it for materials mate?
By the time you have a remap, still upwards of a grand realistically all in, so again you would be better putting it towards a megane if thats what you are after anyway.
The 172 engine isnt an easy one to extract significant gains from cheaply.
what money have set as a budget for more power?
Does the F4R take to NOS well?
FFS not again................

Thought you want cheap insurance? Doing this isn't going to help. Plus you will never do it.
You are the most Indecisive person ever.
And more importantly how well will an un-mapped F4R last under a 50bhp shot of NOS??
The big advantage nitrous has is that if he is planning on changing car, he can either take it off and sell it, or use it on the new car.
The disadvantage is the relatively short lived gains for the money that each bottle costs.
Its a perfectly valid way of tuning but IMHO is suited to topping up the power of an already fast car for when you go drag racing rather than for trying to turn a slow car into a not so slow one like on a standard 172.
The problem with having it on a car thats only 16-170 odd bhp in the first place is it means you will want to use it everywhere, but if its on a car thats 500bhp to begin with thats less of an issue, so I tend to just use it as a top up on turbo cars etc these days.
so your saying ITB's + NOS is the best way to go about thigs
