ITB's Maintenance / Owners Experiences

[Dave.]

Im currently seriously thinking about getting ITB's fitted to my car, and after having the car fitted with cams and mapped it seems like the logical next step. Having seen the quality of work of the Tour De Force AT Power kit, and the way the Burpspeed car starts runs and idles im 95% sure this is the kit i will go for.

My questions are:

How do you find day to day drivability of the car, my car is my daily runner so i want to make sure its still ok to pootle around in.

Do the throttles need balancing very often? Im worried about potential maintenance i couldn't do myself.

Fuel Consumption! I am aware i will lose some fuel consumption, but i have been told by a few people the difference isn't massive, whats the average sort MPG your getting?

And if you had an AC car, did you remove the ac?

Cheers

Dave

Look at the history on this forum mate.

99% of people that have fitted bodies have either sold the car or broken it for parts. There is only one (to my knowledge) that has kept his car but its a track only car now.

 

[Tony Hunter]

A lot of of people had problems with them but most of this was electrical.Nothing is maintenance free but you won't have your head under the bonnet every 5 mins.Some have said fuel consumption has improved with ITB,depends how you drive it of course

 

[Gray]

If you are now considering ITB's why did you spend 1K odd (I imagine) fitting cams, mapping to suit...

Now you are considering port throttles but don't have the "best" cam profile to suit?

IMO I would of gone straight for bodies, you've spent almost half the cost on fitting cams / mapping the standard ECU that the ITB install would cost

 

[Fletcher]

I personally wouldn't fit ITB's to a daily driver.

 

[DanFreemanPhoto]

I personally wouldn't fit itbs at all, you don't need them. A lot of money for not much gains.
Spend the money on track days or something similar.

Or the JMS kit rather than ITBs really. No wiring messing. Standard ECU etc. Around the same power gains (think torque is a bit lower, but nothing major). ~£1500 fitted from memory.

 

[ripp]

I don't have bodies but here's my point: If the sound they make (which is awesome) won't get you mad over time then I don't see why they would be different to a normal car day to day. It's not like fitting a sadev g-box which is un-driveable around town. The engine will remain NA, smooth power delivery, more low down grunt and not much difference in mpg's. Probably they would need a bit of extra care and maintenance but that's part of the experience of having them which can be pleasant why not?

 

[Gray]

I know a couple of people who run ITB'd cars daily and have no major issues...

 

[Dan@SJM]

I ran mine as a daily, and did it for under £1k. as did Russ. if you do a bit of work yourself, and do some searching about for bargains, you could do it for about the same price, then the most expensive part would be mapping.

 

[Cro]

I'm in the same boat as dan, and run mine as a daily. Only maintenance I would do really is clean the trumpets the odd time

 

[Dave.]

Electrical stuff shouldnt be an issue tony, id be getting mat to do a new loom at the same time...

I got the cams at an absolute steal, so seemed like a good idea, dont regret it one bit, needed belts doing so why not?

The cam profile will perform well with bodies, people are to quick to slate the 428's because there not the wildest, but 13 bhp and 6 ft lb on standard inlets is good going, for any cams, schricks don't do any more, except cost a lot more £££

Is starting an issue in the frosty weather for any of you guys?

 

[Tony Hunter]

Matt can sort that anyway through the ecu

 

[Dave.]

Matt can sort that anyway through the ecu

Do u mean the cold start?

 

[Whiteley]

13 bhp and 6 ft lb

The above, for ~1k

Utterly daft spending so much tuning an already highly strung N/A engine IMO, such minimal gains for ALOT of outlay, especially to be used primarily as a road car.

 

[Andyman]

Guessing you never saw the Youtube vid of the TB'd up phase 1 blowing a 280bhp+ old shaped Scooby Sti into the weeds?

 

[Tony Hunter]

Do u mean the cold start?

Yes I doo's.

 

[Dave.]

The thread was for owners experiences in relation to the questions I asked about day to day drivability, what I choose to do to my car with my money is a decision for me.

I'm getting ITBs I just wanted advice on possible drawbacks

 

[twingors]

Supercharge it m8.. That would be epic!

Mate, sack off the rolling road being gospal talk. Any figure is only as good as the rollers its on

Schricks will give more power, their a wilder cam.

Dave you will love them.

 

[marc1330]

Had the ktec kit fitted to my cup mate back in aug and haven't looked back listen to toby!!
On a run the fuel is bout the same if not a little better but obviously if you have a lead right foot it drinks a fair gulp.
It drives pretty much the same as before pretty smooth round town but when you plant it, its a different animal.
Since the weather has gotten colder in the morning it needs a couple of throttle blips now to wake it up and get it running but then that is at 6
Sharkey has over laid my rr graph over his on rebel that was done back to back and its quite interesting

 

[chrispy.clio]

I have run ITB's for a year now and the only thing which has caused me problems is the silly second hand wiring loom, Apart from the loom the car has run like a dream.

Good parts,

Having this sound when you floor it -



Depending on how its mapped could have proper flames (gets better at the end)



Much quicker throttle responce

Car feels much quicker

Having Areocatches on your bonnet is cool lol


Bad bits, only getting 30-35mpg but really depends on how you drive

Loose cruse control ect



You can still keep your AC, mine worked fine untill i decided to remove it.


PM me if you want to buy my old ITB susage filter

 

[172Ben]

From what you have now, and what ITB's will give you extra, i wouldnt bother.

You will have spent like £3k ish in total or maybe more? Should have SC'd it from the start really. Id stick with it as it is, and save the money.

Just my 2 pence.

Graph of back to back runs of my cup and sharkys trophy with inlets and remap. Ignore the wheel horsepower somethin to do with it being a maha dyno . but you get the idea. Mine is in bold

 

[Tony Hunter]

I think Dave knows he's not going to get 280bhp but he wants itb's,thats fair enough good for him.All the haters is like saying why buy that Porka 911
When a Twingo will do,they are both cars, both will get you from A to B.

You got any pics of your sdet up?? Im guessing your using the gen90 ecu, what do you trhink of it so far?? Everything work as it should (except cc obviously)

 

[marc1330]

Yep using the gen90 ecu it seems fine so far no real problems to speak of just petrol light comes on at half a tank but ktec were sortin me an update. Cant fault it for a drive in drive out coversion. Will bang a few photo's up later that i have on my laptop

 

[Andyman]

The only reason not to go TB's is you could get more power going down a different route vs the cost but on the plus side not everyone wants stupid levels of power and all the issues that come with it plus ITB's are ''probably'' the best performance vs reliability?

You could go down the JMS inlet route and you'd only need your map tweeked so would be at the cheaper rate of iirc £1100 area?

 

[Porkie]

I had them few months back together with a Gripper plated diff and loads of other stuff like bushes and stuff. Got a £6k plus bill and as soon a I drove the car I thought yes its 'ok' and 'whoops'
because its STILL just a little Clio and its not that much better than when it was all standard! They are great little cars as standard. You start spending big money on them like I did. (£20k in few months!!!) and you are must missing the point!

ATpower ITB's... Its not an everyday car, but it could be used everyday easily. No problems with cold start and fuel economy improved I think.

They are alot of money for not much extra power at all. Unless you are pretty wealthy or planning to keep the car for a LOOONG time.... I really wouldn't bother at all.

You are never gonna have a really fast car with a 2.0 litre atmo engine in a Clio. So I would NOT fit the ITB's unless you are keeping the car or just love it and dont mind wasting money on it.

 

[Kam.]

the thing is the biggest gains usually are not at peak power when it comes to throttlebodies.

*Thumbs up* Sounded great, too...

If you've got your mind set on ITB's and the finances in place then go ahead and enjoy...

 

[Dave.]

Well I'm still in the thinking stage at the mo, sc would be epic but need more info on the pulley / belt slipping issues and weather the megane keyway'd pulley solves the problem

 

[maynard]

Dave don't sway and change your mind, stick to getting TB's. You know it makes sense!

 

[Tony Hunter]

This

 

[Brett]

I'd get the ITB's. The noise is absolutely incredible, plus you keep the engines N/A character.

 

[DanFreemanPhoto]

^not forgetting the flames hanging out the back!

 

[Matt W]

I wouldn't take the RR figures from powerstation too seriously, my 172 made 181bhp and it's pretty much standard.

 

[Cro]

Well if chris' noise doesn't push you over the edge maybe mine will :rasp: Shameless asw

20k ?!?! WTF

For that kinda cash you should have the quickest Clio on the forum
