You're best bet if you want to keep the 2.3 is to actually buy a 2.3 turbo motor. Best ones are the ones from the thunderbird turbocoupes or the svo. Turbo is the only way to go that will be cheaper in the end. And don't put a turbo kit on your original motor because the motor won't last long because they can only handle the boost and everything from the turbo for so long. If you have any question just ask.
