    K20A3 with A2 Head Turbo?

    I know the A3 head has issues with flowing and hardly enough compression. Looking for an A2 Head and planning on a CXRacing GT35 Turbo and Sidewinder Set Up. Should I also swap out the A3 Pistons and Rods?

    its cheaper to just get a k24a4 and slap a k20a2 head on it. You just need to limit the VTC. I read that 40 was the max VTC you could run on it but i don't know for sure. I never ran over 30 when i had this setup.
    I'll handle 450hp no problem.
    Just tune it properly and don't rev too high.
