6a12 ITB'S

[ljk]

Has anyone done itb's for the 6a12?

Would like to know what gains they produced with or without cams?

and where to get cams?

[Sahin]

What the f**k are ITB's?

[Taz]

Independant throttle bodies.....

Independant throttle bodies.....

Oh lol never heard that term...

[Taz]

Those dots werent because of your question though

[Taz]

I guess ill go first to answer...

No nobody has done ITB's for the FTO
Aftermarket cams arent readily available apart from RPW (as far as i know) and are 2k.

Imo, they are a stupid idea and a waste of time on the FTO - and definitely not suited for street use.
The amount of dyno time and money you would need to throw at it to make it work would be staggering, and even then you will probably lose some bottom end and have to do a sh*t load of engine work to get any sort of worthwhile benefit -any by the time youve spent that 10k+ the amount of other things you could do for that money it renders the whole effort kind of pointless...Then theres maintenance...
Your much better off looking into a 4g93/6a13 swap if you have that amount of cash waiting to be spent on the FTO.

f**k you over estimate things lol how would fabbing up "ITB's" and getting it tuned in with cams be 10k+ lol and you always used to say 4g63 and never 4g93 lol
AND! clint (a guy on this forum) has done it on a 6a12... the one he has in his lotus so ask him...

[Taz]

Thats a completely different story bro - not only a different car, but a custom race setup and its a race application
To put ITB's in an FTO would be harder that simply bolting a few up.
Space is an issue, and everything would have to be custom.
Cams = 2k, Dyno = $$, 6 TB's, custom intake manifold, engine work to support them ($$ very quickly) and engineers cert IF you can get one (assuming it can all fit under there)
I can see that getting up to 10k easy dude
And a 4g93/6a13 is a much less stressful and simple job over doing a custom 63T job - the point being to get away from all the custom work and do a mostly bolt up job..

[Sahin]

A custom intake manifold? what? hahaha
you'd have more space
you wouldn't need to do much if any internal engine work... it's not like you will be stressing the engine that much more...
And really? when did you figure that out? lol you always suggested the 4g63t and never any mention until syntax started doing it

c**t

just

Btw don't listen to me, i'm being a cock lol

Its for my track FTO, so not worried about low end power as its rairly out of mivec.

as far as them not being steetable thats a myth if set up properly.

My friend has a set on his stock s2000 and made around 28bhp when fully mapped with a standalone ecu

Bonnet clearence is tight but they fit quite well, its 6 individual trumpets so no intake plenum.

Basically im asking regarding cams, as i dont want to be paying for setting up twice.

Has anyone any experience of the RPW cams?

[spetz]

There is a user here (Valandis or something like this) who bought some.
He reported that they made a big difference, along with head porting etc. Though for some reason his car always made very little power (even in stock trim) and something happened and he sold it? Not sure of the story

[ZFL45H1]

U could also use works branded cam gears I have seen them on eBay before for 500 but can't find them now
Would be like this though

EDIT: also for the direct works website u will have to get a quote off them though

Only one example of the cams on this forum & it wasn't good. Especially for the $2000+ price tag.

ITB's don't exist. So you'd be hand making them.
We did one recent for my old man's race car, was 4 TB's off a Toyota 4age motor onto a B13b Suzuki donk.
Lazer cut manifold face, welded onto a cut Suzuki manifold, wasn't too hard to make. Getting all the linkages right was a bit of a fiddle though.

Can decode acronym = specialist in that field

Thought since i'm the only one that knows about this i might as well tell you all!

I believe the lack of power was due to the workmanship done on my car. I had countless issues with the set up of my car that i actually ran out of money to get it completely set up properly.

For one the vernier cam gears were never installed thus not being able to get the most out of the cams cos the mechanics were muppets. Not only that RPW's service wasn't very helpful. I had to wait over 6 months for the cams. The first cams they sent me when trial fitted to the engine hit the rocker arms so they had to be sent back. 3 months later the reground cams came along and fitted but then had issues with the timing with the verniers.

The verniers were taken out and the stock cam gears were put back on.

I noticed a considerable increase in power especially torque. The responsiveness of the engine was second to none and even got the dyno tuner impressed.

The big question is it worth it?

Sure have a lumpy idling NA FTO that sounds incredible has great response and all that is great.
BUT for the cost that is involved and the big ???'s you come across as i still have not seen this done successfully is up to you whether you take the gamble.

For me it was a nightmare from the beginning of the build to the end.

For anyone else that tries it could be a different story!

If anyone has anymore questions in relation to it feel free to ask

[spetz]

Going the N/A route requires a certain amount of dedication, especially with a car that lacks aftermarket support in that area. It becomes difficult to maintain that dedication especially when you get into a friends car that has had some bolt on turbo bits added for relatively little cash and the car flies.

Valandis, have you sold off the cams etc from your car?
I remember even if you outright number figures were not overly impressive, you did manage to gain 40% in power which is very impressive.

[clint111]

ITB's..
Well, triples..

[spetz]

From another forum, seems like the OP is well underway:

This is what ive got on the go currently, all thats left is to fit the trumpets and sort the vacuum lines.
