Your choice in the end, but I dont agree with "Nick" at all. Ive had both engines and both have been lightly modified and I know which I would prefer.
FYI - You only need a full computer replacement if you want to start playing with AFR's, Timing, RPM limits etc. or if you want to use larger injectors, you dont need a PFC to put an aftermarket turbo on.
But good luck with the build up anyway
