Don't forget custom downpipe and mapping as well , and a few other little bits , I had the same turbo setup before but sold it as I drove a turbo and supercharged and just didnt like the way the turbo drove compared to the charged clio , charged clio's handle the power so much better
I think itb's have to be sealed some how because you will lose boost pressure through them K-tec done there car with them on. I would just go low boost Paul RS Tuning can map your standard ecu to run low boost, if you pm me your email i have a fitting guide for the low boost kit from k-tec i will send it when i get home later if you want it.
ITB's are generally fairly well sealed anyway, its probably carbs that you are thinking of which are more of an issue, but thats all ancient history now anyway, no one with a brain uses carbs anymore if they can avoid it, lol.
There really is no point to running ITBs on a low boost setup though, its just not going to give you any advantages and will increase the cost significantly.
Unless you just want to do so cause it sounds good down the pub? lol

Basically the plan for the car was get the ground work done before getting boost i.e diff, built internals, r888, cage, plexi windows, itbs and then buy the turbo kit but when i saw this advert i couldn't wait, the price was just too good. I've already spent 3 times more on mods than i paid for the car in 2 weeks so i don't really want to spend on internals yet, so low boost for now until summer time when ill get engine out built to a good spec and go for as much boost as the little thing can put down sensible
As I have already told you, most ITB's are fairly well sealed anyway, about the only place you are likely to lose any boost is down the spindle of the throttle shafts and thats no more or less of an issue really than on a single TB.
You seem to be trying to remember something you think you read once, I'm talking from experience of multiple cars I have mapped on ITBs and a turbo, there arent any real issues in doing it, but there also are very limited gains to be had.
I was actully told this off a trader on here who has built many of engine's including my new one, just car'nt remeber what was said not going to get into an argument but they had alot of work to do to get it to work they had problems with boost leak i might not know as much as you but know what i was told not what i read.

Have a look on there some build but cost fortune's

Thats it some build but cost a fortune
Double post first one did'nt work then it worked
According to that article, that car isnt on bodies as such, they have done it the same way that I did with just using the throttle body outer shells and no plates with a shared plenum and a single throttle, this is the one I did the same thing with:
Its only still ITB's if you have one plate per cylinder, not one shared plate.

That look's a canny build, like i say im not a mechanic that looks like what they have done aswell. I wanted one of them red tops out of the calibra turbo put in my corsa gsi years ago when the belts went would of been epic,went for the astra gsi insted then got a calibra turbo not long after.
Thanks, it was a great build until the engine block split 
Had steel crank, steel rods, forged pistons, touring car spec head, block all line bored etc, but with regards to the block itself it turns out that at around 600bhp or so they just cant cope and crack, quite common knowledge now and we have ways around it, but we didnt know that at the time I did that build (was about 7 years ago)

600 bhp thats a epic build pity about it splitting the block. What have you been able to push one to now if that was 7 years ago?
There are ones out there now at 900bhp+ using the ZLet block instead which is easier to re-enforce at the point that my one failed (the 900bhp+ ones are not done by me, ive moved onto other engine types now and the only c20let's ive been involved with recently have been 400-500bhp or so trackday cars rather than really chasing the numbers)
900bhp bets thats mental to drive,aye you must know your stuff so have you done any thing with a clio engine yet? or will you be would be intresting to see what you could do if you can do that with a vauxhall engine. There's some nice clio build's on here.
Ive not personally turbo'd a clio engine yet, although I did support MWM with some mapping on their turbo project as they were trialling a different ECU (Mtech V4) to it than the ones they normally use (Omex) which I have a lot more experience of mapping than Mike and Jack and we do quote often help each other out with various projects.
Clio engines are fantastic, not just the F4R but also the older F7R like in my mk1, but I am fed up busting gearboxes so have gone honda engine and box for the clio turbo I am building at the moment.
Our other mk1 is staying F7R on a custom inlet I made a couple of years ago to replace the ITBs I took off, which is along the lines of an RS2 manifold though, this is it with the plenum cover off, I did that with a view to turboing it originally before I got so pissed off with the boxes! :
My mrs has just ordered an RS2 for our 172, thats probably as far as we'll go with that one for now as she is using it as a daily, I might turbo it at a later date though and go with the Audi gearbox conversions that are being worked on at the moment by various people, as that then makes the clio engines viable again, i might not have gone honda in the first place if there was that option when I started the other project, but TBH I love honda engines anyway so am quite happy with that.

You've got a bit going on there did you not try the DCi JC5-128 box ive been told there ok for over 300 but you have to weld the cir clip in.bet the honda engine will make the clio shift.
p.s
Here is the inlet above with the cover and throttle on etc:
although that was when we were first mocking it up, so its all a bit tidier now and powder coated etc.
Could you not have made one of these for the Mrs car that look's good doe's it work aswell or better than the rs 2
No, ive never tried the DCi box, TBH even if it is strong though like some claim (and TBH im not convinced about that, I will need to take one apart at some point and have a look if its actually any beefier as I suspect its just the ratios are the only difference), you still have the issue of fortunes for a diff etc.
We could have done, but she likes the look of the carbon fibre, and the RS2 is already there so pointless spending ages creating something my self when it can just be bought so easily.
Not sure how my F7R one would compare as not ever had an RS2 on the same engine as they dont fit (head is totally different) I would imagine the RS2 will out perform it though, its had a lot more development, i just made that one for something to do on my own car, not as a commerical product so its not had the same R&D that the RS2 has had, its a fantastic product.
They look really well made in real life, me and the Mrs are down MWMsport (the official instalation agents for the RS2) quite often as we know mike and jack well and when she spotted one down there she was very keen on it partly from the looks as well as knowing the performance difference.
I should think its going to end up upwards of a grand including buying the box itself and then the driveshafts and the new clutch and flywheel etc, its not a minor change to make.
And probably nearer 1500 with fitting.
If the kits are good, im sure MWM will be keen to fit them as I know they dislike the fragile 172 boxes too!
If it does come in around 1500 quid fitted though, I guess its not too bad if you do it at a time you needed a new clutch anyway, as thats a big chunk of that saved anyway.
