Bike Throttle Bodies
I know its been discussed on here before, but is anyone converting bike throttle bodies to run on their car engine.
I ask because I've just acquired a set of GSXR 600 throttle bodies, which I plan to fit to my 1.6 zetec, and wondered if anyone else has done it
 or if I made a mistake

Interesting Idea..........
i was looking at this idea but it became a bit complex , i thought if i had a downdraught carb ,(32mm ish), I could replace it with even one bike
throttle body plus controller.
But I got talked out of it........

unfortunately no one has talk me out of it yet.
I know it can be done because it was being discussed on te V8 owners forum, with someone who actually done it (although he used gsx 750 Throttle
bodies and a 2.3 zetec(?))

It looks interesting, my CVH engine already has most of the sensors you need, but how much is a control unit ( Emerald?)

There's an open source ECU available, parts available in kit form for about $100 US. It's a fuel only controller but you can also build a
companion ignition controller out of cast-off Ford ignition components (info on ignition in the FAQ section of the website).

Personally, I'm not an electronics guy so I haven't taken the plunge yet but if you're up for it it appears to be fairly robust,
lots of successful users and good online support.

P.S. just to get somewhat back on topic, I think the Bike TB's are a fantastic idea. Bespoke one's cost the earth and IMHO offer no
advantage to properly sized bike ones.

A Emerald ECU for fuel and ignition is about £500 and is a good choice as the software it uses is very easy to understand and use, beware when getting
an aftermarket ECU as some are software locked and only dealers can change settings (Weber). If you are going for something different from the norm
then a rolling road session will be needed to get the best results. Emerald quoted me £250 to map from scratch which can take 2hrs but then again
could take 6hrs so not bad value.

I'm going emerald ECU route. Costs inc of VAT are £650 for ECU and £230 for full mapping service.
Very reasonable i think and a nice guy to deal with too.
BTW the 2.3 aint no zetec! Its based on the mk5 escort RS2000 engine which is basically a pinto with a 16v head. It was a Ford stop gap to give cos
they hadn't finished developing the zetec yet.

Isn't the RS2000 a Sierra DOHC block with the 16v head?

There was an article in one of the kit car magzines a while ago about using bike throttle bodys and a citroen ECU which can be remapped with comercial
software apparently. It was making a point that you can use parts from a breakers and the company concerned would map the unit for about £300.
This may be a cheaper option and maybe it would be possible to obtain the mapping software and do it on the road.

So was that citroen ECU fully mappable?
Does anybody know the formulas to work out the size of the manifold and trumpets?
