A Turbo or Super Charger will get you some extra power, but it may shorten the life of your 4.3 Litre V6 engine if you push hard on the gas pedal. You will need lots of time and money to perfect the performance of a turbo engine. You may be able to find a Super Charger Kit for your Blazer, but be prepared for a lot of testing and fine tuning. The simplest and most economical improvement you can make to your Blazer would be to install an 8 cylinder 350 cu.inch GM remanufactured engine if it will fit your existing transmission and under hood space.
