Carburetor or fuel injection?

fuel injection is a far more controlable and efficient way to deliver fuel to the cylinders. There is a reason we went from carburetors to fuel injection (performance vehicles first).
The flip side is that injectors require specialized tools and or procedures to work with them, and can't generally be "tinkered" with (without a computer), as LBC owners tend to like to do.
From a performance standpoint, Injectors are almost always better. But from a do-it-yourselfers standpoint... welll. You have to admire how simple and effective the old SUs were, but the numbers (and drivers) showed how much of an edge the petrol injection gave the Triumph TR5.

Oh, and to answer your other questions. Yes it is possible to convert to fuel injection. There are "universal" throttle body fuel injection kits that you can get from various after market parties. Moss Motors is supposed to finally debute their MGB spcific throttle body fuel injection kit sometime later this year. I believe some of the more expensive kits will allow you to approach some of the power curves on newer cars, but it'll take lots and lots of tinkering around. Also, I think some of the better injection kits are rather expensive... more so than the expected $1K MSRP of the Moss Motors kit.
I know fuel injection has been added to MGBs by various people, and some of them have documented some of their work on the net...

It really depends on the car. Fuel injection can be a definate advantage in a performance situation, and it may be fairly easy if there are kits available for that particular car/ engine.
On the other hand, If you have a good running car with a carburetor and are not trying to squeeze every last ounce of power out of it, then you're probably better off keeping the carb. It would probably take more time, effort and cash than it would be worth to try to engineer a fuel injection system and get it set up right.
For an everyday driver, the original carb setup will be every bit as reliable and efficiant if properly maintained, and there are other people out there who could help you fix it and know the common problems. (not so with some One-off special setup that someone built).
But that's just my take.

In general I have to agree with you Banjo. I for one am probably not going to convert to Fuel Injection even when Moss Motors does start selling their kit. Mainly because the price of entry is a bit steep for me at this point, especially considering the Moss kit isn't supposed to provide that much of an improvement in power (or so i hear).
