I have a 95 4.3l 5-spd 2wd with a throttle body injection system and i was just wondering if it was possible to switch it to a CPI system and what parts do i need to do so if it is possible.:D

You could, but why? The reason the cpi makes the power is mostly due to the camshaft, it is considerably more agressive.

That is the only advantage i see, and you can put a camshaft in a tbi. Also, tbi's have upgradeable injectors, and they don't have fuel leakage problems that the cpi units have. It is also easier to upgrade a tbi to better '96 up vortec heads than it is on a cpi injection setup.

Where is the best place to get those upgraded injectors i am having problems with mine right now and it seems that getting those and a new cam may be my best bet. Thanks
