How easy it to fit cams or itbs
- Thread starter chale989
- Start date
any idea of cost of itbs or cams just as the materials.
ktec actually have a you tube guide to fitting itbs, maybe worth a look
cams will be a bit more difficult, full cambelt change ect

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.

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
wayyyy out of the price range. i would rather put it towards a megane sport
what price is it for materials mate?
sounds good but way out of price range
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.
yeah i was hoping for cams to be around 500 and then re map 200ish.
looks like il wait and get a turbod car
700 ish.
I dont think you'll find a decent company to remap to suit hotter cams for as little as 200 TBH but I stand to be corrected.
Also realistically as you are taking the belt off etc you really need to be adding in the price of a cambelt kit to that as well, thats how I was ending up over a grand.

Nitrous is the only cheap way to get power.

Should get you a reliable 25bhp on tap. Get a proper controller and I dont see why 50bhp extra wouldn't be possible with some colder plugs and real fuel.

Yes, they are quite strong internals so a well setup nitrous kit works well on them.
Be careful though if using on a chipped car, as advanced timing and nitrous are a bad mix.
Nitrous is a way of getting extra oxygen into the engine very easily, which in turn allows you to burn more fuel, it can result in huge increases in power (ive seen around 100% more on some engines I have been involved with, and my mate Trevor Langfield aka the wizard of nos, has seen upto 600% increases on some very specific older bike engines etc)
A typical large nitrous bottle is 11lb, that will last around 10-12 minutes on a 25bhp kit, and cost about 60 pounds to fill, so around 10p a second.
A typical small nitrous bottle is 5lb, and will last around 4-5 minutes on a 25bhp kit, same price per second as same amount of nitrous consumed per second.
50bhp = double the price and lasts half as long.

Yes mate, the moment you turn it back off the engine is exactly as per standard.
And its only active at full throttle, so its surprising how long it takes you to do 12 mins in normal driving.
25bhp on an F4R is such a smooth increase though that its hard to really tell its doing anything until you go along side another car that hasnt got it, its not like cams where its all dead and then comes alive, as it adds the power all over the rev range relatively evenly.
50bhp though, is properly cool, you really feel that happening.
Its very trivial to swap between 25 and 50bhp, just a change of jets, takes only a minute or two.

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.

Stalker?
I'm considering changing to a non sport until a get a turbo or tune this and keep it for years.
It shouldnt make any significant difference to how long the engine lasts, much like a megane F4RT with the same rods and similar construction pistons has more power and yet still lasts perfectly well.
Nitrous? Seriously? Is it 1992?
ITB's are easy to fit even for a beginner - there's nothing complex about it
It only took me 2 hours with basic tools and a trolley jack
As said K-Tec have a full set of youtube videos that talk you through the whole thing
Get an Omex 600 with a pre-made 172 loom and the wiring just plugs in, get a base map and you're ready to drive. All you need to do is get it mapped
Cams I wouldn't do yourself - timing the 172 engine up is a bit of a skill - you're better off taking it somewhere
However it will be a lot easier to fit cams after ITB's because you won't have to strip all the inlet off to get to them
ITB's on a 172 you're looking at about 12-15bhp increase
Then if you put some wild cams in and another remap you'd be looking at another 15bhp ish.
210bhp should be achievable with ITB's and Cams

172 track thingy
nothin wrong with a shot of nos or two lol and plus cams and throttle bodies are old school tuning 
but tbh if it was me which it will prob be hopefuly in the not too distant future then i would have a go at fitting ITB's they dont look to complex it was just the wiring that scared me but going off what phil said it shouldnt be too bad

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
Thats not a combination I often use anymore TBH although have done in the past.
The most common place I use nitrous for these days is turbo cars. Its absolutely awesome at cooling the intake charge and at spooling a big turbo too so its a perfect marriage with a turbo, the T34 on my sierra spools far quicker on the nitrous than the standard T3 did without it.
My ITB cars tend to be used on trackdays, and nitrous works out too costly for this really as you spend so long at full throttle, i'd get through several 11 pound bottles in a day at the track, and they retail at about 60 quid a fill.
172 track thingy
ye suppose so with the lack of torque in an N/A you always use all the revs to get it go places :S NOS really is a drag car mod tbh isnt it.
my m8 has done a hybrid diesel project and was thinking of using either water meth injection or NOS as a cooling agent both really costly but both show so much potential gain on his car!
sometime i wish they fitted a boosted unit into the clios lol

The MWMsport turbo car works really well, i dont know why Renault didnt just put the megane turbo engine in the trophy or similar and make it a real limited edition not just a bit of paint and different seats and some suspension tweaks.
I think that sort of conversion might become more popular now that there is quite a big owners scene around the 172 with forums like this, it gives people inspiration to get stuck in and the cars are now cheap enough to be ok to risk messing around with.
Squirt of nitrous on that would be fantastic performance wise I'm sure, but sadly I think it would need the conrods uprating first.
