cams vs itb's
- Thread starter Mr Plums
- Start date
Thanks mate.
Evo 5 RS
Will do mate thanks.
I'd base it on when your belts are due. If soon get cams, if not get bodies. You'll get more money back from the itb's if you ever wanted to sell .
if only. Belts done 10k ago so don't need replacing apparently.....where do I start :S

This TBH.
Ive got a full decat milltek and i did have a bmc cda but ive taken it off, im ordering an itg panel filter and air feeds on fri, the standard airbox is quite good tbh with the 2 air feed holes, im going toplace them in a better place for more air flow tho.
I wish
Correct, the belts were done 10k ago.
Ill have a think about what i want, it was easier with my vxr, turbo back exhaust, large front mount and a map, job done lol.
Basically, it makes no difference, would all need re doing. Any other way is a hodge

It's a strange mentality, if you want cams you want cams. It's that simple. What are you going to do, wait another 5 years till the belts are due again and then get the cams? Something to look forward to I guess lol...
I'd actually disagree with this
I have Jenveys + Omex, got 195bhp. I've seen quite a few cars on here now with cams hitting 190bhp.
Cams cost about half what the ITB's do
The ITB's do sound really nice and you get a sharp throttle - but it's not, in my opinion, worth the extra £1500+
I'd whack cams in and one of the new K-Tec induction kits, should get 190+ out of a 182 easily.
You'll keep driveability and some fuel economy too
Lol im new to renaultsport, ive owned vxrs for the past four or so years now which i know inside out, im not bothered if i need the belts changing or not, my origional question was...
Is there alot of difference speedwise between a cammed and mapped 182 vs an itb'd 182 with standard cams. thanks.
Im just wanting to know what the best bang for buck is so take your un-useful comments elsewhere and grab yourself a budweiser!
Im undecided what i want and i was asking for some info!
Providing all you want is a peak figure to tell your mates down the pub your logic is bang on.
If you want a nice wide spread of torque though, I'd take standard cams and bodies every time personally.
If you want a significant increase though, just turbo it!
Thank you very much mate, just the answer i was wanting.
I knew there wasnt really much difference bhp wise, which is why i was asking is their much speedwise on the road as im not very clued up on either tbh.
Thanks again
So the torque comes in much earlier with boddies?
It would be nice to see a graph of both.
Yes it does, although it depends on the length, to get bodies to work well you need to lose the slam panel.

What Jay is saying is they change the way the car drives, that is drivability. You gain a lot more of it through throttle bodies throughout the entire rev range. The sharp throttle response is mainly because you come from fly by wire to cable. Cams will take a little from low down and give it to you top end, which although gives you a nice peak figure of 190+, it will never drive as well as a throttle bodied clio with the same peak figures, or for that matter be as quick
Yes i understand mate, thanks for the info.

I might have a set going cheap soon, just a quick pitch there

I R No explain proper
Evo 5 RS
lol x
North west I guess try Paul at RS tuning I’m sure he could sort you out with ITB’s and do a great job on them too
Price wise if paying someone else to do the work then I guess around 2.5k-3k
If you can DIY and then just get the mapping done elsewhere I guesstimate about 2k with new bits

Clio 172 Cup Mondial
don't itb's ruin fuel consumption?
Evo 5 RS
No, not if they're mapped right.
I averaged 36mpg on my Nurburgring trip in May, over the whole trip
At low rpm you will see some minor losses typically, but on a run there really shouldn't be much in it, 60 bhp of air to cruise down the motorway hasn't changed how much it is and the air fuel ratio and timing at that point should be no different to before if mapped correctly.
Problem is the mapping tends to be focused on the top end, ignition at part throttle is totally unimportant in terms of peak performance and people want to pay as little as possible for mapping and then will judge it on what it goes like, so mappers potentially end up in a situation where they can't afford the rolling road time 'wasted' on economy that the customer doesn't want to pay for.

Cheers mate will get my saving head on
LOL I fully understand that ITB's give you more torque lower down and the peak rpm over a more usable range
HOWEVER cams and a remap - you're looking £1200. ITB's and a remap - you're looking 3k minimum
I still don't think on a road car that wants a bit more oomph that it's worth spending £3k on a car that let's face it is only worth £3k.
Just my opinion. I guess I'm one of the rare minority that did it and just thought it was money better spent somewhere else
For 3k you could whack some cams in, remap it, fit some KW V2's and a diff.... just sayin'

I know my response isn't cam or itb's but if your looking at spending 3k then could you not turbo it for that much.
Totally agree with all of that, especially the point that getting around a track fast isnt about power anywhere near as much as people think it is, a cup racer with their almost standard power outputs is quicker round a track than most modified road cars with far more power, I couldnt keep up with the racers at donnington for FCS in my turbo for example over a full lap, despite the fact I could walk away from them on the straights.
Evo 5 RS
You could yeah, and it wouldn't drive as nicely as a TB car with your right foot
I think they're worth every penny, but in all honesty everything you say about your experience with ITBS just makes me think yours aren't mapped right Phil! I can fully understand why anyone would be against spending that much on a 10 year old Renault though, obviously.Similar threads
