GT Phayer Posted November 5, 2016 Share Posted November 5, 2016 Hello i have been looking into doing a coil on plug conversion when i get my new starlet and just after some more information. I have read somewhere that i can use Honda k20 coils ?. Also a Corrola 4EFE trigger wheel and crank sensor. I was just wondering once the distributor is fully removed and blanked off how do you go about monitoring cam position tdc? Any help will be much appreciated. Quote Link to post Share on other sites
triple j Posted November 5, 2016 Share Posted November 5, 2016 Standalone ecu will do all that from trigger wheel, 1 rotation of the crank = 2 on the cam's. Quote Link to post Share on other sites

Stu Posted November 5, 2016 Share Posted November 5, 2016 With an aftermarket ecu you don't have to setup new triggering unless you want to, the standard pick ups in the distributor are fine, just remove the cap/rotor and add a blanking plate. K20 coils are a good option or 2zzge coils - there are two coil variants for the 2zz, both are the same except for one is slightly larger diameter and needs to be shaved down to slide down the spark tube. Have run these many times for customers with good results. Quote Link to post Share on other sites
GT Phayer Posted February 26, 2017 Author Share Posted February 26, 2017 Ok thanks so i can leave the crank trigger and just use the dizzy blanked off ? Thanks for your help Quote Link to post Share on other sites
Stu Posted February 27, 2017 Share Posted February 27, 2017 Unless you have crank triggering already just leave the dizzy in place and use the triggering inside it (24tooth = NE pin, sync = G1 pin). Remove the rotor and making a blanking cap as you wont need them - cap it something like you can just make out in this photo Quote Link to post Share on other sites
aleximport25 Posted February 27, 2017 Share Posted February 27, 2017 ^^ very very nice dude.out of interest is the power steering pump off in that photo or have you used a blue pulley for something else Quote Link to post Share on other sites
TimD Posted February 27, 2017 Share Posted February 27, 2017 Stu, is there anyway of identifying the 2zzge coils that fit without the need for modifying?Diameter, or other markings would be useful. Thanks Quote Link to post Share on other sites
Stu Posted March 1, 2017 Share Posted March 1, 2017 90919-02239 are the ones that need a slight shave down to fit (less than .5mm needs to be removed)90919-02238 are the ones that fit without any mods. Quote Link to post Share on other sites
TimD Posted March 1, 2017 Share Posted March 1, 2017 Perfect, thanks! Quote Link to post Share on other sites
GT Phayer Posted March 12, 2017 Author Share Posted March 12, 2017 Any help or tips to wiring the coils in ? i know you have 3 wires.. 12v ... Ground and trigger Quote Link to post Share on other sites
Stu Posted March 13, 2017 Share Posted March 13, 2017 Fairly straight forward to do. Left to right looking at the coil connector (not the plug on the loom) the wires are ground (head/inlet), trigger from ecu, not used, 12v supply. Depending on your ecu wire then sequentially or wasted spark. Getting the tacho to work can be a bit tricky - I just change the primary resistor on the tacho PCB inside the cluster and then run it of a low level drive from the ecu (usually Links for just about all of my customers). It kinda depends on how good your ecu is. Quote Link to post Share on other sites
GT Phayer Posted March 16, 2017 Author Share Posted March 16, 2017 Anyone have any pictures of coil on plug wiring loom ? Quote Link to post Share on other sites
Stu Posted March 17, 2017 Share Posted March 17, 2017 I said above what the pins are. Depending on what ecu you have and it's capability you can either wire wasted spark (one output to coil 1&4 other to 3&4) or sequentially (one ignition output to each coil). Sequential wiring just make sure output #1 goes to cylinder #1, #2 to #2 etc, and bit to firing order. It's not possible with the stock ecu. Quote Link to post Share on other sites
