This is the mother of all opened ended questions for the week.
Bang for the buck? 57 trim bold on ct26. Either rebuilt ct26 or a JT56 which is built off a t4 platform. Personally Id go for the JT56 as the t4 bearing housing has a much better oiling system.
If you had more money (manifold or adapter, wastegate, down pipe, intake pipe, power steering relocation kit, oil lines etc), then yes - a Holset hx35 or 40 or a hy35 or HE351CW.
