A question for me alone should be PM'd to me so that I can respond personally ..
This message could be answered by more than just me .. there are many other Canadian's visiting this section as well.
If money is an issue, the weber carb would be the cheaper route to take. If money isn't an issue, then go with the ThrottleBodyInjection .. as far as which one to go with, that's your decision, based on what your plans are for your Jeep.
Now, there are many suppliers of the stuff you are looking for .. you can visit Canadian 4WheelDrive Magazine
to see their list of suppliers .. Al (the owner, editor, and all around great guy) tries to keep up ontop of all the goings on within the Canadian borders .. including people making great Canadian products that you can purchase. Get a subscription to the magazine, or pick it up in Safeway. I found the 3rd issue of the magazine there, soon after I met Al (in person, even!) and got a one year subscription. When that subscription ran out, I visited Safeway faithfully to get my copy.
As thanks to the guys who helped me make my Jeep bigger and better, I bought them a one year subscription each (and got a 2 year for myself
). To me, its well worth the money!
