I own a 1991 W/T Suzuki Sierra 1.3L JX.
Ive purchased a MK1 GTI motor and loom and ECU off this forum as well as a fuel VL Fuel pump.
Ive created a list as follows:
- Sierra Clutch/Flywheel and pressure plate. Good time to upgrade to a heavier duty one with the Gti engine as they dont last too long.
- G13b MK1 Suzuki GTI Swift motor
- G13B MK1 Wiring Loom and MK1 Wiring diagram (Wiring diagram is completly differnt for MK2/3)
- 12-14" thermo fan using the Stock radiator is fine but use the shroud.
- GTI Exhaust Flange and $220 Sierra 1300cc Extractors. Heat the hell out of it to clear engine mount and other misc things lol.
- MK1 ECU
- Mazda 1986-89 (not 1990 and above) 323 GTX 1.6L Turbo Distributor Cap AND rotor button. I modified the shit out of hte GTi dizzy to get this to fit. Works perfect

- VL Fuel Pump (you dont need a low pressure pump and surge tank unless you are doing crazy 4WDing. Or drifts at 8000rpm with less then 1/4 tank of fuel lol
- Use Sierra Sump onto bottom of G13B (As Swift Sump hits)
- Use normal Metal Fuel lines but swap out old hoses with EFI rated hoses.
- 4L of (5W30 to 10W40) Oil and corresponding oil Filter.
- High Pressure Fuel Filter (get rid of the low pressure useless fuel filter)
- Run a Radiator hose from the top pipe of the radiator to the thermostat now located at the rear of the motor!
- 5-7L of Coolant
- New Spark Plugs (suzitech triple or twin spark plugs for $28.00 at Suzitech)
- Mitsubishi Astron Thermostata housing (P/N W022A) or use a SA Gti thermostat housing to run the coolant temp sensor for the thermo fan.
- New timing belt so not to replace it later and pulling the motor back out.
- New water Pump and Oil pump as to not replace this later.
- 2 1/4 inch press bent Exhaust or 2inch Mandrel.
Im a mechanic by trade so should be able to work most of it out myself. Plus the wiring should be quite easily also. I have now finished the conversion so all the above parts is how i completed the conversion with it fully functioning.

P.S the G13BA (old motor) tested 90psi on the first cylinder and pretty much 110psi on the rest)... bad joo-joo seeing standard Compression should see 200psi in each cylinder :(
