listen before you get into this project you need to fully understand how much money your going to spend to do either swap.
With that said it is always easier to swap a tranny than to built a turbo engine out of a naturally aspirated engine. Most people just think they can buy a bolt on kit, have some half-ass mechanic throw it on and take it out and race it. What they dont tell you is even at 5psi sooner or later it is going to blow. The problem is the internal componets are not and were never built to run boost or handle that kind of HP. The only way to do it correctly is to have the motor bored .40 over and have forged internals installed. Then you need headers, turbo, intercooler, piping, intake manifold, ecu, engine wireharness, oil lines for the turbo, and all the electronics to run everything.
