VVT = variable valve timing.
It basically means that in addition to electronic control over fuel injection and spark timing, the engine also has control over the times the intake/exhaust valves open and close, which means the engine can automatically adjust itself so more power is available when you want it, but the rest of the time the engine can still be efficient.
variable valve timing enhances your engine performance, by allowing the engine to adjust the valve timing in ways that draw more fuel and air into the engine to produce more power at specific times
EFi = electronic fuel injection.
EFI is electronic fuel injection which basically means your fuel is injected electronically instead of mechanically like a carbuerator does.
EFI, you cannot beat EFI over VVTI
sfi - sequential fuel injection efi - electronic fuel injection
YES, They are the same engines. There's NO difference what so ever.
Electronic Fuel Injection (EFI)
The difference is a 5.0 EFI engine is making 225hp stock a 5.0 HO is making 275-280hp
EFI simply states that it's a fuel-injected engine( as opposed to a carburetor set up), and that's the fuel injection is controlled by electronics rather than by a mechanic fuel pump. GDI tells you that not only do you have a fuel-injected engine, but that the injectors are sitting closer to the combustion chambers(maybe even inside) which supposedly is good for fuel consumption and a clean burn.
Electronic fuel injection
It depends on your skill level, what engine you are replacing with what engine, what vehicle you are removing from and putting in, tools, and how much time you have. Is it EFI or carb? Are you going from carb to EFI? Carb to EFI? It can take a day or it can take a year lol.
Where are the timing marks on a 1992 Toyota Paseo 16 efi 1.5 liter engine?
try checking the connection between the speedometer and the engine or wheels

I'm not a mechanic / technician but from what I understand the camshaft position sensor on the Ford 4.0 liter EFI , V6 engine is on the top of the engine , at the REAR of the engine , near the firewall . You won't be able to see it ( at least I can't on my 1995 Ford EXPLORER , which also has the 4.0 , EFI engine )
