because it has just been rebuilt with all the top gear. On the engine dyno it pulled 556hp at the fly on 20 psi i can run up to 25psi and 32psi on gas. I was told i will pull 10s in a sw20 mr2 thats why and i only thought what gen was the engine today. I just want to know whats different to all the other gens. the engine has all internals done and a hi flow ct26 hpc coated. Just want to know what was differnt when the engines are stock. My other 3sgte which i belive is a 185 has a differnt inlet manifold to this engine. Can u change the manifolds ova if the 205 is better ???
