Generally low impedance is under 4 ohm's and high more in the 11 or 12 range. Yup, theyr around 2ohm.. Grey top Quote Link to comment Share on other sites More sharing options...

The ones I used on my starlet and Mazda look a lot like these ones, I just used a bit of aluminum plate and thermal paste.

No resister needed, bang straight into the ecu (add a 10amp fuse) to the fuel injector 12v wire for safety and bobs your uncle.  Depending on how your loom works those early ECU's have a 'safety' relay which powers the injector positive side. Just switch the source to the black/red line for that (which is the power side of the EFI relay, goes to Fuel Pump relay, Coil and ECU) if you have any issues instead of having the unnecessary other odd relay they use, switch it over. 1 Quote Link to comment Share on other sites More sharing options...

Funny that..  not much left to do on it, probably a days work. Couple of vac lines, finalise a bit of wiring, sort some radiator hoses/outlets etc. refit carpets and modify the console, fit the lower shifter boot. and find a suitable pod filter.   Re the pod filter, I got a k&n on for the mazda that had an angled sleeve..   Quote Link to comment Share on other sites More sharing options...
