How to find which engine you have or the parts attached to it?

Which Engine?: Inline 4, with 8 or 16 valves ? Valve covers below: or the V6 -24 valve 

The 8v TBI SOHC Engine cover is black painted, the 16v MPI is silver color and is stamped (cast really), “16 Valves” Clear as day.
Suzuki, for whatever reason uses VIN code #2 for both 8v and 16v motors, making parts hard to buy. So, open the hood ! Look here for G16A/B info.
Gander below: Notice how the 1.8L (J18/20) SPORT engine has the oil filler up front !

J18 or J20

The CARB fuel INDUCTION intake sysetm. Shown only to see missing EFI “electronic fuel injection” system!
Seen on old Vitara’s or the USA rare 1989 , 1.3L Sidekicks. Carb.’s are seen in other countries 10 years past the legal limit here, 1989.
Best way to fix an old CARB, is to put in a Harley CV carb.”ez tune” , a Weber and using a wide band oxygen sensor meter, tune it fast) Or like this Calmini.

These Carb parts
are mostly unobtainiuim. (the most rare element on earth)
This below photo, is not a Throttle body. It is a stink’n CARB. ( the only problem with carbs is getting parts, kits, and jets size data after 25+ years)
For 100 years we boiled them out (means cleaned with a magic heated chemical.)then kitted them, and made sure all jets matched your altitude.
Then lots of by the FSM book adjustments.
(Old guys, used GUNK BOP or Bendix parts cleaner then and heated it up, then in year 2000 all that old “FAST” stinky stuff is illegal, replaced with weak cleaners, took me 8 days to soak one carb, in this.)

TBI is a Down draft Throttle Body Injected EFI, not to be confused, with a Carb. Look carefully.

MPI is a side draft Throttle body EFI. (Multi- Point Injected)

End Carb era , enter EFI , USA: (by EPA laws)
See my extensive list of EFI throttle bodies, here.The TBI is complex and loves to mess up (leak air).

In 1996 Suzuki moved many electrical parts. Fuse box wiring, moved the fuel pump and main relays, and extensive OBD2 mods.
EVAP 2 systems started I think, in 1996.5 , mid year. (yes, more complex and more parts to break)
In 1997 Suzuki moved the TCM (tranny brain) into the confines of the ECU and renamed ECU to PCM. So, don’t look for theTCM separate module.
The 1998 switched to full plastic main air pipes, no more metal pipe (alum.) and no more water heater there in said pipe.
16V Engine Rebuild photos 1997 have clear views of EFI induction/injection parts.

  1. Where can I buy injector/ carburettor injector for my Suzuki G16a 1991?

  2. I am looking for diagrams of the fuel and vacuum lines to the carburetor for my 1986 Suzuki Vitara, Vin # TA01V-162054.
    Please email them to me.

    Thank you

  3. Hello Gang, any contacts for a 1994 Sidekick Exhaust Manifold 16V ?
