LOL I don't know what you call "no problem." Crank trigger is a bit of a trick, and you will need an appropriate manifold to mount injectors. It IS expensive no matter what you do.
People make fun of TBI and there other options besides FI tech an Sniper. Mine was an older TB only with Holley external CPU. So more programming options
If TBI is so awful because "wet" then explain to me HOW DO CARBURETORS EVER MAKE POWER
