who is the manufacturer and does it work more reliably than webers
I'm having a new engine built and I'm going with fuel injection. I'm going with kit from CB http://www.cbperformance.com/catalog.asp?ProductID=1665 I'm also going with crank fired ignition. Unfortunately, I won't have the car back on the road until May, so I can't comment on how the car drives yet.
fi is good but expensive, why not kadrons for carbs, with an o2 sensor you can really dial it in. bill
Bill, I have been wondering what is needed to use an O2 sensor to adjust my carbs.
Do I need to permanently install a sensor in my exhaust system?

I am collecting the bits to do it using a Megasquirt ECU and EDIS ignition.
Far more control than the CB ECU, open source, and cheaper. Not turnkey however and it requires you to learn abut FI - not such a bad thing
Buy the CB end castings to inject right at the valve. I am using old Weber carb bodies for TB as it makes the linkage easy, but ones of a GSXR have the same spacing as IDF's and c/w the injectors

We use Redline injection at Mendeola and is not just more reliable then carbs but willl help you engine last longer. Not to mention the Horse Power increase.... Fuel injection the only way to go.
michael iam in fla for feb. so dont have access to mail every day, any way, you have to weld a bung in the exhaust system, then you can screw in an 02 sensor,and drive around and monitor it or go to a shop with a chassis dyno and use theirs, run the cae and watch when its lean and where or rich and where, well worth the money, but you can ball park it too, but not perfect. bill
Having an O2 sensor and carb's is fine but, in the big picture, you can't fine tune the carbs to run at all conditions as you can with FI
In other words, you can re-jet the idles for most driving under 3,200 RPM's and you can adjust the mains and air for situations above 3,200 RPM's but, if you've adjusted for 70 MPH and you travel at 85 MPH, you may be running lean. Likewise, if you slow to 50 MPH you may be running rich?? All depends on the jetting/altitude/barometric pressure etc.

Look into Megasquirt. All the bells and whistles, and total control over all functions. No other system offers this degree of freedom. As a bonous it is the cheapest but requires you to learn about FI
Integral data logger for tuning or do it live as you drive. Oxygen sensors, knock sensor. TPS/MAP or both, rev limiter, launch control, turbo, nitrous, barometric sensor, flex fuel, E-20 85 or whatever fuel your heart desires, etc etc.

Robert - you make learning about FI sound like a bad thing LOL
Lots of watercooled guys run GSXR or R1 throttle bodies with Megasquirt.
these TB's can be had for <$100 on ebay.
This route isn't an open the package and plug it in way, but does allow you to learn - understand - customize for you - and save money - only downside is it takes time

The GSXR has the same spacing as IDF's so the manifold part is fairly easy. As you say cheap and cheerful with integral injectors and TPS
Linkage needs to be fabricated and I have been thinking of a BMW Boxter dual output cable but gone no further than thinking.

I started building my Megasquirt FI four years ago. You do have to learn about FI in the process, as well as the software interface tools.

I chose to stay with one central TB in my design. Many go with dual TBs, and then find that they have a problem attempting to adjust the two throttles to achieve a low idle. Only one side will have a Throttle Position Sensor to feed data to the ECU. If you want maximum power and bling, go for the dual TBs. For a nice idling, street car, remember that all mass produced cars have a single TB. There are a lot of threads on shoptalkforums about this choice. Knowledge is power.
Megasquirt is great fun, time intensive, and infinitely tuneable. If you are the kind of person who likes learning new concepts and has basic fab skills, then go for it. Also, there is that feeling of achievement when, after all of the wires, fuel lines, sensors, etc. are installed, you first fire it up.
Nothing against carbs, but we are a bit different than the usual hot rod owners.

Please excuse my (usual) ignorance, but I took the FI off my super beetle in order to fit a rotary a/c compressor and I wonder if it is worth trying to put it on my speedy. I have a 2110 cc with webber 40s or such.
well - the injectors / manifold / pump and tank could be useful, but the TB is too small and the FI brain is setup not for performance or tunability.
lots of guys run a mixture of OEM parts for the fuel rail/manifolds, but use performance injectors/TB's and electronics.
so - in short, don't throw it all away - you can use some of it.

Thanks...I'will try to figure it out when I finish the Superbeetle...i wish I didn't have to eat so I could finish my projects!
