cams vs itb's



  182/RS2/ Turbo/Mk1
Silent scone, have you ever driven a clio with a LSD? The difference it makes to how the car drives in tight bends is far more than the difference a set of bodies makes to how the car drives IMHO.

I reckon if we got two clios, put bodies on one and a diff in the other, the diff'd one would be quicker round most tracks, especially if it rained.
 
  Evo 5 RS
Suppose it depends on the state of either car lol. Nope, never! But in an ideal world you'd have both. I meant more that you'd still have pretty much the same power band as the standard engine by going down that road. To me at least it's day and night driving both a cammed engine and a TB one

Not dismissing one or the other but personally for the sake of shaving a few precious moments, I'd have the throttle bodies for the s**ts and giggles alone.





Diff can wait lol. :eek:


Or just do it right first time and boost it, but there we are. LOL
 
  182/RS2/ Turbo/Mk1
When you do try a car with a diff, I think you will be pleasantly surprised how useful they are, especially in terms of how much sooner you can start laying meaningful amounts of power down after the apex of tight corners.
 
  Evo 5 RS
Well you've got some hanging around lend me one lol. If it's anything like the wheel though you might be waiting awhile :eek:.


Digressed a tad though, throttle bodies over cams every day given a budget
 
  RB Clio 182
My corsa nurburgring had a diff, that was unreal round bends, ive nearly wrote the clio off a few times after coming from that thinking i can take bends at the same speeds.

A diff makes a massive difference on any car, they sort of feel as tho they pull you around a bend rather than sliding wide, they can catch you out tho, they are that good.

The clio is pretty bad in the wet too unless its the avons on the front that came with the car.

Going for boost though is the same jump again from cams to itbs isn't it..

Really approx figures as it varies so much with how people do it and what bits they use but IMHO these are approx fair costings:

Low pressure build parts (incl aftermarket ecu) : 2K
Low pressure build labour and mapping : 1500
High pressure additional parts : 250
High pressure additional labour : 500

So anywhere between 2k and just over 4K depending on the power you want to achieve and how much of it you can do yourself.

If you can map it and do all the labour yourself, you should be able to bring a high boost conversion with 280bhp or so all in for about 2.5K
 
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.

Hahaha it's not really about how they drive - it's just pure value for money they aren't worth it IMHO unless your racing in the tin tops and need to squeeze the last 0.4s out of a lap

It's cost me £3-3.5k for the bodies for 195bhp and some pornographic noise
But I settled on coilovers that were too soft for track, ran out of money before I got decent tyres, and it wheel spins out of corners
I 110% think I'd have been happier spending £1200 on cams and a remap, £400 on AD08/R888/Direzzas, £900 on a diff and added the rest to the coilover budget and go KW V2's or AST's...

The powers great and the noise is awesome - but it's not very usable on a car that doesn't handle too well unless you're into 1/4mile stuff

I should have learnt from my 106 days - everyone who bodied them to 175+ bhp just said the money would have been better spent on a diff so they could use the power they had before getting more. I fully agree with this now

As I say it's horses for courses mate, when I went for the conversion, I much preferred the drive you get from ITBS.

It depends how you look at it, boost is arguably much more practical on a road car if you're looking for a nice easy drive and extremely fast, but if you need the car daily you're putting a lot of strain on not only the box but other components as well. Both have their advantages, but if your only requirement is that you want your Clio to be very quick in a straight line....buy another car. Kidding, boost is the way forward. But the op hasn't mentioned it!!!

You live and learn, and without going epic hypercritical I can honestly see where you're coming from if I could turn back time. But that doesn't mean I regret buying ITBS, the F4R should come with them standard. That would clear this up lol.

On the note of coilovers I can relate. Not selling adjustable suspension for the mk2 I can stomach, but selling them at a premium and not sorting out defects after 6 years is a piss take. FU Bilstein.

On the other hand phil, if its a longer term project, you have the engine sorted now and can do the tyres and coilovers and diff next :)

Then you will have a fairly good clio.
which owes you 10K+ and is worth 4k tops oops

Thanks for that chip. For me personally that's well over the limit of what I would want to spend on MY car, seeing as I would need to include all the labour costs too.

Do you do much track work mate?

Nah not in the Clio, I managed to get it out once this year but it's been one thing after the other after I managed to get it mapped. Hopefully next year it will be doing more in different guise. It's a long term labour of love lol.
 
it will never drive as well as a throttle bodied clio with the same peak figures, or for that matter be as quick

We agree to disagree, mine on 438's is as good TBH - reaches the same top speed on track as Burp and James....lap times down due to non commitment on our part (car peseravation and all that) - so really horses for courses and actually comes down to "what are you actually prepared to pay for your BHP" as this is the focal "figure" point for almost everyone on here. world over perhaps...Not me though....££££ or lack of get's my attention.




(also haven't read all thread yet, just had to reply to you first)

I drove an AT and EC1 equiped car today. Yours is better. I then took the owner out in mine. He wants to convert to jenveys.

You need to come out in my car Pete, you'll be converted

I think you are right Pete and I would go as far to say not only is yours as quick but I think its definitely faster than mine on the straights

I agree with the quality differences and if I was doing it again then I would run Jenveys so no doubting that but what is the difference in car when driving the two cars back to back Dan? Is it actually worth the swap like your customer wants to do? At the end of the day I just see it as a flap that lets air into the engine and the length and shape of the bodies are similar on my AT’s to the jenveys that i’ve seen so what definitive gain would I see from swapping?

Yes they've lost my business permanently sadly. If they were priced at £500 then they're not bad - but nearly £900 for non adjustable billies with faulty seals in is ridiculous.

Yeah I would still have done ITB's eventually as the noise and power delivery is awesome - but I'd always recommend other people do the suspension, diff, brakes first - because fitting bodies to a car that can't really use the extra power is the most frustrating thing ever.
And yes I've come to terms with the black hole which modding cars is long ago lol

Screw ITB's they sound awesome but for the money it aint worth it if budget aint an option supercharge it!!

oh sorry lol ive had 438 cams, induction kit and decat + exhaust and remap and car drives really well massive improvement, im happy with the difference but i havent ever been in a clio with ITBS so i cant comment on which one would be better but i dont think there would be much in it and for the money you would save you could buy a lsd aswell :)

We need a graph of a bodied one lol.

I think id go cams and a map, the bodies seem too expensive for the gains by the looks of things, if i wanted to spend 3k, id stretch another thousand and supercharge it (i wish).

it puts out the same amount of smoke as a diesel bus is what he means! we have to push it out of the workshop before we start it because its that bad!

FLOL it honestly started on the key when I had it. It's seeking attention..it's diabetic too. Cold start uses half a tank though
 
  Evo 5 RS
To be fair the map is bang on for the most part. I have no fcking idea why the cold start is so rough though. Bit of that'll do approach going on somewhere. Nevermind.

Not like it matters now, it's fcked anyway
