Convert S2 to carb/s ?
Discussion
I have spent the last 2 days pondering the practicalities of converting the S2 to carb/s. It seems that so many problems arise from the electronic induction system (I need to get mine sorted) that moving to a carb set-up might be a good idea.
With my simplistic head on, I can't really see many problems. Just imagine, no throttle pot, airflow meters or ECU to worry about !
A simple downdraught Webber or a Holly with associated inlet manifolds should be available & shouldn't cost a fortune. The sale of the redundant injection system would even recover much of the cost.
Has anyone tried this conversion before & any thoughts on the downsides ? I really yearn for a simple engine that I can tune and fix myself !
Cheers

I thought of doing this to my car, and here are a couple of points to consider.
With carbs you will need to use downdraughts. By the time an air cleaner is fitted on top, you will possibly need to cut a large hole in the bonnet for it all to fit.
You could find that you loose out on mid range torque and power with carbs, although top end power should be as good as now, maybe even better.
A proper mapped ignition may be the better way to go, and would probably cost a similar amount, plus you could get all the 'lumps and bumps' smoothed out of the rev range, and possibly more power throughout the entire rev range to boot!
Whatever you do, it probably won't be cheap! I am going to use 'Superchips' to rolling road map my existing Ford EEC IV ECU.

Check out burton power and order their catalogue - they seem to be pretty well up on that sort of thing...
Thw way ahead with this engine IMHO is what Jas's is doing.
Carbs will cause significant issues with body clearance, set up and ongoing set up.
What Jas is having is slightly different to what he is saying but there is possiblity for a couple of routes.
1 - Buy an off the shelf pre-programmed superchip that will do as it says on the box.
2 - Have a new fuel map 'burnt' into the existing ECU by someone who can do it and really knows what they are doing.
My personal preference would be the latter option as this fuel map will be arrived at afteer time spent with your car on a rolling road and therefor it is specific.
Superchips undoubtedly do their job, but you have to get them checked and set up by someone in the know.
Carbs is interesting idea, induction roar aswell as exhaust note.....urm...
You would have to get a new inlet manifold for certain though..

Thanks for the comments but it seems that I have run into a brick wall on this one. The inlet manifold is the problem. A 2.8 one will not fit & the guy at Burton says that there are no other manifolds available! Ho Hum.
Guess it's back to the injection route
Get one made? Surely SOMEONE will be able to do that?

Ah! Paceracing, how does this superchip thing work.
how much will it cost.
where do you get it from.
does it need to be specialist fitted?

First of all, Inlet Manifolds for carbs. - Yes someone somewhere WILL be able to make a bespoke one, probably for around £300.
Secondly, the 'Superchips thing'.
You can take your car to Superchips (somewhere in Oxfordshire I think) and for around £400 - £600 they will fit one of their chips to the existing Ford EEC IV ECU and fully map your engine throughout the rev range on a rolling road. They tell me it will take around 2 hours of mapping, or there abouts, or you could just buy an 'off the shelf' chip and plug and play, (not as good as a full mapping session though).
Johno is correct, I am having quite a bit more done to my engine, and it will need a full mapping session to get the best out of it, although it also works well on standard cars.

Has anyone looked into the Dastek Unichip piggyback system as an alternative to superchip. I was told by a rolling road tuning station who fitted both superchips and Dastek Unichips that better results with the cologne 2.9 engine had been found using the Unichip. I can't vouch for how reliable that information is, but more information on the Dastek Unichip can be found at Ric Wood race developments website www.rwood76.fsnet.co.uk/
