ITB's Guide?

[Schweppy]

Very interested to find out more about exactly what is required and how to fit ITBs.

If people with ITBs could add comments about how easy they were to fit, a guide to actually fitting them/tools required and expected gains. Also any info on reliability issues would be great.

Finally, any info on engine management would be very helpful too. Would it be possible for example, to run ITBs on a remapped standard ECU?

Cheers.

There's a pretty picture guide in one of last years PFC mags.. can't remember which one

I don't think it's an indepth guide as such, but it'll give you the general jist

 

[Schweppy]

OK thanks mate i'll have a dig about. Interested in doing it myself as a project.

I'm sure one of the Barron/Bazzon boys can help me with this...

Carl will be along shortly to tell you in more detail.

but...with ours being a second hand set we had to have a few small custom brackets made ect so was slightly more difficult than a normal one.
We also had a PH2 loom which is differnet to a PH1 one so this is what took most of our time, we had to test all wires and sensors then rewire most of them to the standar ECU and OMEX.

If you were to buy a new set from GDI or KTEC i would say that with a little time you could fit them no problem, we d not done much like it before but we soon learned all the sensor and what went wear. We did have help from a few of the gurus on her to clarify some things.
TBH it is alot of fun doing it and you will learn a lot doing it, just dont disconect the fuel lines in a enclosed small garage :<

We have problems with having the standard radiator ect but this will be sorted in time. Mainly that we had to cut some of the fan surround away so we could run a filter housing

TBH carl knows more than me cos he did most of the research but i reckon i could do it again if i had to

We talked about mapping the car on a standard ECU with paul, but we were not able to trailor the car down to him so we just went with the Omex that was on the original kit.

Cheers dude. Exactly what i wanted to hear. Just this second PM'd you!!! haha.

Fitting
easiest thing about ITB's is bolting them on. Its very simple to 'fit' itbs the hardest bit is getting them to work. What you will need to do is remove the standard inlets. Bolt the bodies onto the head. Fit a modified thermostat housing with a temp sensor in it. fit the cable throttle (this can be abit chewy, two people is recommended). Fit a breather filter onto the head breather pipe (182 only has one).

Wiring
if you buy a kit from GDI or Ktec (OMEX management) you get a fully assembled race loom. This means its just a matter of disconneted the standard wiring to the map sensor(not needed), injectors, VVT sensor, TPS and a few others. With the new loom its just a matter of connecting up the new loom to the appropriate sensors/injectors (very easy as you get a manual). The new loom just plugs into the omex.

Management
you have a choice with this. Near enough most ECU's out there will run a ITB setup on a 4 pot car (correct me if im wrong). The easiest choice is an omex as you can get a full loom which just plugs in. You can go for an emerald/link/pectal etc but im not sure on how they do the wiring (would probably mean cutting/soldering and following wiring diagrams). Paul at RStuning believes he could get an ITB kit working on a standard OEM ecu, this may be possible but would be best to speak to him about the option of that.

Expected Gains
On a standard 182 engine i would suspect you will see around 200bhp. Meaning a 20-30bhp gain. Its not the bhp gain which is important with these its the throttle response on the low down torque in which they provide. The RB 172 has a near enough flat torque line from 4300-6500. Meaning it feels pulls alot better from low down.

Reliability
Reliability of these is down to the map tbh. Once mapped correctly they will start aswell as a standard 172/182 and will produce near enough the same fuel economy when going slowly (obv once you hit the gas the mpg will drop much quicker than a std car). General road use they are fine, low down torque is much better and the noise when flooring it is to die for.



(correct me on any of this if im wrong, im not a guru)

PS Bazzon knows s**t

if you want wiring details and stuff, PM me your email address and i will send you them over. 3 sides of excel spreadsheets lol

 

[Bazzon]

Yeh im the Muscle, carl is the brains thats how it generally is

 

[Schweppy]

Thanks very much boys.

Much appreciated.

I'll be in touch shortly!

Oh and a demo would be nice....

Mallory Park the 8th of FEB then. Else the car is nearly always up north

Thats not too far from me. Whats on then? Cant see any info on the website.

 

[Bazzon]

Its a Ford owners club day ROSC derby, We have a friend who had booked it and his focus is not complete so we are going along instead. Open pit for 9 - 5.

 

[scott1205]

show them fords how to go on

 

[CalClioCup]

Whats running around town at low speeds like, and is idling any different?

I'm talking about the K-Tec kit with premapped Omex for use with standard cams... as I'm very interested in doing it. Another thing, how have people found it affects their insurance polices in terms of pricing?

Sorry for the hijack Schwep!

 

[Bazzon]

Ours is fine at low speeds, but then agen we dont drive it a great deal on the road. Our s has a low idle probably lower than standard car.
If you go for the KTec kit go for the proper size trumpets not the small ones.

Personally i would never use the full potential of them on the road so would not consider them on a road car. They are spot on for a track car. But ofc thats IMO.

 

[CalClioCup]

Thanks for that. How much did it affect your insurance premiums if you don't mind me asking?

I didnt think it'd seen a track since fitting them?

It was ment to but our track day got moved its now on the 8th of Febaury. We have not seen the full potential on the road tbh, yeh weve had some blasts in it and your soon way above a sensible road speed. Also our car is on FMPs ASTs so its Very hard on the road any how.
