B20/Ls turbo

Have a ques. about the B20/Ls coversion. I've just recently drop a B20 long block into my 97 rs. The motor is unbelievable. The torque is out of this world. Posted a 15.5 on street tires with no modifications except for a air intake. I'm sure it could do better if an expreienced driver got behind the wheel. Anyway on to my ques. I want to go turbo eventually.
Should I go CrVtec and then turbo or just use the Ls head. Money wise I think I should go with the Ls head. Not quite sure witch one is going to benefit me most. Thanks. Harry's#1.
