Re: 305 tbi supercharger?

Better place to start is to do the usual bolt-ons like headers, full exhaust, intake, retune of the ECM, etc. Those will give you a good boost in power without the expense and aggravation of a supercharger. Technically any one that fits a carb could be adapted to TBI, but due to the limitations of the system, its something your better off not doing. There used to be SC's made just for the TBI systems, but they were not that popular.

Also, are you sure its TBI and not a Q-Jet and LG4 305? TBI did not come out until 87/88 as the baseline LO3 V8 for the sport coupe that replaced the LG4.

Yeah as far as I know no TBI's were available in thirdgen's until 88 actually. And www.tbi-superchargers.com has a bolt on kit for the 305 tbi

Re: 305 tbi supercharger?

You would need a fuel management unit. procharger mage blowers for TBI trucks that utilized FMU. I see they discontinued referencing for TBI in latest catalog. FMU added fuel pressure I believe. So a new fuel pump is required.

Aftermarket ECU is a better idea to manage A/F and timing.
