Just trying to find out info in regards to a list i found a while ago in regards to doing this conversion. The thing is i cant find it. So ive created a new one.

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 s**t out of hte GTi dizzy to get this to fit. Works perfect :) $50 instead of $300 for a n angle drive kit is sweet!
- 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.

If anyone needs any more information dont hesitate to call me on 04 10 756 872.
Or add me on MSN at beejay_is_@hotmail.com

More then happy to help out anyone in need.

Regards,
Stewy (04 10 756 872) Newcastle

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 :(

there is few guys here that have done the conversion. Im sure they will answer your questions.

If you are running the GTi motor use the recommended viscosity. 10-30, or 10-40 or thereabouts.

Thanks mate,

Thing is, i am trying to create a list to solve any else asking Questions.
No doubt when i complete the conversion i will ensure the list is 100% Accurate.

you will need to custom fabricate some extractors , modify the thermostat housing , sort out some piping from throttle body to airbox or a custom airbox or pod (if you dont want to go under water..) also find another throttle cable . thats all i can think atm ...

good to see you found a motor.

I am not sure where the sierra engine mount attaches to the block but if it is the same place if does on a swift, then you are going to run into a little problem

The rear mount dowels are in the wrong place on a mk1 bottom end. I have a mk1 motor in my mk3 swift and i had to do a little bit of custom work to make up a mount for the rear

Just some food for thought, cant confirm any of this as cant remember exactly where the mounts are in a sierra

By the way, you didnt happen to buy a black sierra a few weeks ago did you?

sierra engine mounts to the same place as mk1 swift so no worries there

If you're using the Sierra box then the starter should be in the same place. You will need to use the Sierra flywheel too.

The VL in line pump will be fine, but put it as close to the tank as possible. No need for a surge tank unless you're into extreme off-road. If you are then the G13B is the wrong motor choice anyway!

Having a quick look at your list, you're missing the following:
- EFI fuel hoses and filter (replacing all original rubber lines)
- 90 degree distributor converter (available from SuziSport)

Thats what he meant by the mazda distributor cap, its very shallow and doesnt take alot of room up, therefore not requiring firewall "massaging"!!

Ah the joys, I put a 1.6 vitara motor in my sierra, carby 8 valve dunga and if I had my time again id put a GTi donk or jimny motor in!

Good luck champ, they are a handful of fun the Sierra's!

Cheers Superduki.

Ive always had a major soft spot for the sierra, my next project will be one (with a gti motor of course)

Good luck with conversion mate

Yes it should have a rail. Bonus for you is that the MK1 reg is removeable.

Naah it has the fuel rail of course. BUT what i want to know is, if the FPR comes standard on the factory fitted on the rail? If so why would i want to remove it?

Also you mentioned regarding running no swirl put or prime/low pressure pump?
So let me get thsi right. You installed one pump, no surge tank and no swirl pot, AND you are utilising the standard sierra tank???

Sorry, typo. I meant to say that yes it has a reg, not rail. :oops: You can remove the stock reg if you want to run an aftermarket unit. After 20-odd years the stock one might be on its last legs.

I haven't done this personally, but a friend did the conversion using a single high pressure pump with no surge tank and no lift pump. Many other carby -> EFI conversions work the same way. As mentioned the pump needs to be close to the tank though. HPLV pumps are designed to push a head of fuel, not pull a long draw. If you're worried about it then fit a surge tank and lift pump. If your particular Sierra has an in-tank LPHV pump then you can use that in either case.

Anyone know the exact part numbers for the Rotor Cap and Rotor Button?

I asked for a Mazda 323 GTX Dizzy cap and rotor button. Unfortunely i think they may have ordered the wrong one. Seeing i went through two diff people for the two parts listed, this could be the case.

Also ive just found he part number for the Thrmostat housing W022A. Runs at a 90 degree bend which is needed to clear the sierra firewall.

Found out a few things.

Part numbers that are needed are as follows:

- Thermostat housing W022A - Mitsubishi Astron (NOT MAGNA)
- Rotor Button from a 1989 Mazda 323 GTX 1.6L Turbo (Make sure its turbo and NOT Part number EP780)

You might need to clarify. Astron is the motor found in a Magna. The part number you quoted might be for the Sigma, which also uses the Astron series motor.

Yes understood. However its defeinitely that part number.
Its not the 2.6L model Magna.
The Astron was suposedly a older "Sigma" which came out around the time of the Magna.
Realistically you can use any housing and adapt it to fit.
