Starlet FAQ's
Do I need a crank sensor in order to use coil on plug (COP) or sequential injection/ignition on my 4E-FTE Starlet?
The answer for 99% of people is no. This is a common misconception which has been banded about the old starlet forums forums and it’s a common question people ask us. Most common aftermarket ECU’s with 2 trigger inputs such as Link, Haltech etc will work perfectly fine using the standard 4E-FTE cam sensor which is located in the distributor.
There are 3 sensors within the distributor housing, a 24 tooth and 2 cam sync pulses which are 180 degrees out from each other. As the 24 tooth wheel doesn’t have any missing teeth you are required to use both trigger signals as there is no way to determine top dead centre (TDC) without using 1 of the 2 cam sync pulse signals.
We personally run the stock triggering (4E-FTE cam sensor) on our own Glanza V.
If you only have 1 trigger input on your ECU then I would advise you fit a crank sensor. If you have a later 4E/5E engine then you can fit an OEM Toyota 36-2 crank trigger wheel. This is suitable for EP82 engines produced after 07/1994 and all 1996-199 Glanza V EP91 engines (oil seal groove on engine block).

Which injectors do you recommend?
The answer depends on how much power you intend to make. Up to 350 bhp I would recommend Bosch EV14 550cc injectors.
Toyota – STARLET GT, GALANZA V 4E-FTE – 4x 550cc BOSCH EV14 Fuel Injectors – USCAR Connector
Upwards of 350bhp I would recommend Injector Dynamics 1050XDS (Part number 1050.60.11.D.4) injectors. These injectors are huge, but because of the fantastic injector data provided by Injector Dynamics you can easily dial in idling on the small 4E engines.
