I agree- and the point with the M45 recommendation was performance/dollar ratio and ease of entry. They are common as the rain, can be found cheaply, and give you about as much power as the stock injectors and clutch can handle. Then you can do all the other turbo stuff and sell the SC. I would not spend a single dollar on getting more performance out of the SC setup unless it was something you needed to eventually go turbo.

My DD is a Sienna van, and I'm pretty sure it is in fact faster than my thoopacharged 1.6 Miata. As you can tell I only drive the manliest of vehicles.

Heck, I managed to get my M45 setup for $550 (and then a second one for about the same, need to re-sell that...). I am just building the car with exactly the same supporting mods as needed for a turbo build. Sometime down the road, I will dump the 1.6 and super, add 1.8 and turbo and go from there. It will be fun comparing my car and my friends who's is turbo (or will be when they are both done in a few weeks.)

You could probably sell both those M45's and pay for a 1.8 swap and 6 speed lol. I've seen people pounce on full kits for like 1200-1500 with all the fuel cards etc.

That is the eventual plan. Though these didn't come with all the needed electronics. I am not loosing money on them.
