Cold Air Intake or Wait for Turbo?

I did a quick Google search for Mazda3 cams, but all it came up with was Cosworth camshafts for the Speed3.

It might require a little more digging to find some cams...

I'm sure you've already done your research, but just for added info.

One issue fixed... I found a guy that will do custom cams for the car. Apparently he's worked for some tuning company for 30+ years and will give me a good deal. I'm trying to work out what size I can bore the engine to... it's going to be a few months until this actually gets off the ground but I figure if I can start ordering bits now, then it'll be a lot easier to get it done quicker. Less downtime without my car

I'm mildly concerned about the transmission issue but without really knowing what this car will put out when the build is finished, I'm debating on whether to gamble and pay the money for a better transmission with more suited gearing or just roll the dice and see what happens.
