K20A3 head with a turbo is definitely...unusual. That's kind of like a K20C1 (probably should've just used a K20C1 unless the turbo was really cheap).

I still think you should've gone with a K20A. The fuel economy would be probably more than 10% better, no need to take out balance shafts, and you'd have 8600rpm on tap if you felt like having some fun with a Japanese ECU.
