Hello Kenney and welcome to the forum. There are several ways to convert from a throttle body injection to a tune port injection. However the information that you gave is insufficient to accurately answer the question. How much is the budget for the conversion? Are you going to install this yourself? Are you looking for a stock TPI system or a modified system?Is your 84 corvette stock or modified?Do you have the stock camshaft? The easiest way to convert to the TPI is to get the whole system from a 85-91 corvette from a salvage yard like Contemporary Corvette, website-www.contemporarycorvette.com. You could also get complete systems from a number of after market places. There websites are: www.tpis.com, www.hotrodlane.cc, as well as others. The parts that need to be changed are the intake manifold, the upper pellum, the distributor,the entire air cleaner assembly, the fuel lines, the fuel pump, and possibly the sending unit in the gas tank, the wiring harness for the injection, the computer, and all the sensors. Factors vary according to what system you choose to go with and what year that system is based on and whether it is a mass air flow system or a Manifold absolute pressure system. So you see I really need to have more information from you about what it is you want to do so I can give you more detailed information. Thanks :chevy: MKOTZE
