Keep your engine, but use all turbo electronics. Much easier to tune and run more power later on. The biggest problem I had with the NA electronics turbocharged is the transition between no boost and some boost or if you drove at that point, like climbing a hill. The car would surge, stumble, choke run terrible. If you hit it harder and had lots of boost, there would be no problems. I had 440cc injectors and an AFC. There's no way to tune for the boost transition. My engine is NA intake manifold, turbo block and all turbo electronics now. I'll have it dynoed at the end of the month at the Suprashootout. Going to dyno at 20psi and hoping to hit 400+whp.... :biglaugh:
