Re: TBI to TPI ?
Did you read the tech article on swapping TBI to TPI? Did you 
and read the hundreds of other threads on this topic?
Yes you will need a new TPI throttle cable.
Yes you will need a new TPI TV cable.
Yes you will need a new TPI fuel pump.
Yes you will need a new TPI computer and chip.
None of those TBI parts are compatible.

This will give you some good direction, and its what Kevin was refering to.
Strangely though, its listed under misc instead of carb/F.I.
