Upgrade Perodua Kancil to EFI fuel system (with/without Turbo)

Perodua kancil is a well know fuel saving compact car operated with its carburator fuel system. Nowdays, every new car comes out with Electronic Fuel System (EFI) that will quarantee you a lower fuel consumpation especially on compact car. EFI system is an electronic-controled fuel injector by the ECU (Engine Control Unit) to inject the fuel trough the nozzle under high pressure to the combussion area. By converting to EFI system, you can feel the different especially the on the fuel consumpation, engine smoothness and of cause a powerful engine becasue of the L2/L2s 12-valve head compared to 6-valve on Perodua Kancil.  While using the carburator fuel system on your Perodua Kancil, you satisfied enough with its fuel consumpation. Just imagine if the carburator system converted to the EFI system.. Fuel consumpation should be MARVELLOUS!!!

If you want to convert to EFI system without changing the original engine block (for the purpose of maintaining the engine number), you can take this EFI kit from Daihatsu Mira 660cc L2/L2s. This is the list of item you needed to make this project accomplish, for non-turbo (N/A).

1. 12valve L2/L2s engine head (recommended L2/L2s turbo 12v head for future upgrade to turbo)

2. L2/L2s engine wiring set (recommended L2/L2s turbo wiring set for future upgrade to turbo)

3.  L2/L2s Ecu (recommended L2/L2s turbo ECU for future upgrade to turbo)

4.  L2/L2s Intake Manifold

5.  L2/L2s Exhaust Manifold (N/A manifold) 6.  L2/L2s Double Layer Radiator
7.  Double Layer Gasket/Metal Gasket.
8.  L2/L2s Fuel tank

*note: L2/L2s is a Daihatsu Mira model in Japan.

If you want to convert the non-turbo (N/A) EFI system to turbo, list of item listed above is needed but need to change the N/A exhaust manifold to turbo exhaust manifold. But make sure you use L2/L2s turbo 12-valve head and L2/L2s turbo wiring set including the ECU. For information, L2/L2s N/A engine wiring cannot use for turbo engine as well as the N/A ECU. Problem in tune up the engine, unless using the engine management system such as E-manage.

When playing with turbo, the stock Perodua Kancil piston also must be change to L2/L2s turbo piston. For the 660cc model, no need to rebore the piston cylinder but still have to use the l2/l2s turbo piston because Perodua Kancil piston is a high compression piston while l2/l2s turbo piston is low compression. High compression piston not suitabel for turbo engine especially in high boost.

But for 850cc model, you need to rebore the piston cylinder because the size of 850cc piston is smaller than 660cc model (660cc piston = 68mm, 850cc piston 66.8mm).

There are privileges in which the 850cc will be 882cc turbo when coupled with a larger piston (piston l2/l2s) and higher block that was only availalbe on 850cc block (660cc block lower than 850cc). 850cc gearbox can be reuse and this will give your car extra power compared to L2/l2s 660cc turbo.

But if you have a budget around RM5000, it is advisable to buy 660cc Daihatsu half-cut set from auto half-cut store for a better functions of other electrical equipment such as air-conditioner and power stering. Some of the combined-wiring (kancil wiring+L2/L2s EFI wiring) may cause air-conditioner fail to function properly. But there is a solution for this, by using FICD (Fast Idle Control Device).
