KMiata dyno day! K24A2 swap Miata spins the rollers! 

You can use k24z3 kit with k24a2 if you go turbo. The tubular frame with a2 kit is for exhaust clearance.

Without a lot of extra work the kraftwerks kit doesn't put out more than 200 wheel. Plus then you're dealing with all of the cooling issues inherent in the bp motor. Furthermore I plan on going turbo with this in the future and this is just a much better starting point than the bp.
