Weber vs Throttle
Hi,
I got a stock Duratec and I'm thinking about getting a weber kit. What kit do you prefer to install with the duratec and are there any other
price affordable solutions how to put together weber that would be quite easy to get and to install, for example from different parts and so. I would
welcome any idea. I dont want to spend £2.000 on a kit so I'm looking for something with better value for money, thanks for any ideas

why dont you use bike thottle bodies you can get mainfolds ready made for around £150 then a set of bike throttle bodies around £100 little bit of
work need a nice ecu job done should be able to do it all for around £700

Bike carbs would be better VFM than Webers, just as much power and stay in tune better, ZX9R, GSXR1100 etc yield good 40mm carbs, try Bogg Brothers
for a manifold, £300 should see you up and running.
ITBs probably better still, I'm building a set in between more important jobs, using GSXR750 K1 bodies.

Dont bother with carbs, waste of money
Go for fuel injection everytime

Bike throttle bodies would be fine I think. But in this filed I'm total novice. I don't even know what parts I would need to put it
together, where to get them and how to put everything together, so sorry for this step by step procedure

Sorry, When you say a "Weber kit" do you mean one of the Weber Alpha packages designed to fit the Duratech ?
OR just fit a pair of Webers 45's to your Duratech ?

Are going through IVA cos emissions may be an issue with carbs, get some Throttle bodies and Injection like these

By a weber kit I meand something that I would buy and install and that's it. No other changes and tuning would be necessary. But I realized how
expensive those kits are so I have to go another way, but am not familiar with bike throttle bodies at all, thats why I'm looking for info that
would explain me step by step what to get, where and how to put it togerher

this will get you started if you go bike ITB, its a good little mine of information.

Duratec is probably slightly different, but this describes the general strategy.
Big bike carbs can work, but bike ITB are much better (emissions, efficiency, emissions, idle quality, emissions, and tunability, and not 15+ years
old like most boke carbs now are).

If you have a whole stock Duratec, is there any reason not to use the standard inlet?
Admittedly you would require a stand alone ECU like a megasquirt to run it, but it would make an easy install and retain all the standard breathers
etc as ford intended.
It should also see an improvement in power as there are likely to be improvements in the exhaust system and induction over stock that can now be
exploited and be very drivable.

I would like to have at lest 185HP or more, I'm not sure if that power would be possible with standart inlet, Bike throttles looks like a good
alternative I think

Perfectly good reason then, just depends on your budget etc.
I've run R1 throttle bodies on a Pinto and tuneing it myself sure wasn't easy compared to the Duratec with standard inlet we've got
in now.
No idea of horsepower but it's a hell of a lot faster than the Pinto with TB's and much more drivable.
Could always run the standard inlet for a year and learn, then swap over the following winter to TB's if you still desire more power.

So I would get bike throttle bodies and a manifold to put it together but what about the ecu or how will the engine management know how to run this
setup?

Whatever inlet setup it would require a programable ECU and mapping unless you had the complete car loom, imobilisers and key etc and even then it may
not run properly without the wheel speed sensors etc
Bike TB's would require a manifold making from scratch, a kit or by purchacing a complete setup, the TB's may also need re-spacing and a
fuel rail.

I know that it would need a perfect fit manifold, I saw some duratecs with bike TB already, so I think it could work and they must have it from
somewhere. I red about the re-spacing of bike TB as well and modification of fuel ramp but what I still don't know where to get programable ECU.
What are the suitable manufacturers of ECU for this setup?

Probably the cheapest ECU setup would be a Megasquirt from somewhere like www.extraefi.co.uk
Or others are available such as DTA, Omex etc systems.
If your setting it up yourself it's your choice otherwise it makes most sence to use whatever your local/best rolling road prefers using and has
experience setting up.
If you still have it already I still wouldn't rule out using the standard duratec inlet, and buy a higher quality or feature packed ECU and then
upgrade to say Jenvys at a later date or when you chance upon something better for a good price.

A lot of Kawasakis [ZX6R, ZX9R] use rubber inlets with flange ends that can be bolted to a homemade manifold plate. As long as you can respace the TBs
and get rubbers of the right size a manifold can be put together at home for about £30.
I did this with my ZX6R carbs and it works great.

I would go for Jenvey 45s with megasquirt.
