Awesome improvements! Sure would like to,see a vid of how you decide to configure ins and outs for a PMU. I still need to do that project on my '67 fastback.
Did this project require an additional port being added to the intake manifold somewhere to support the idle air control valve? If yes, where was it located? Thanks in advance.
I know it can be done, but why? Not sure I understand why one would go to all this work by hacking up a perfectly good running TR6, or otherwise properly rebuilt and tuned Zenith-Stromberg carbs are very good performers.
To be fair, only TR6 enthusiasts would say that being able to run is perfectly good. It all depends on your definition of "good performers" and the amount of reasonable maintenance that is acceptable. EFI has numerous benefits over carbureted setups in virtually any application on the street. On an application with as many negatives as these systems I'm the TRs, it really is just a matter of how much it is worth to you. You could be focused on the gains in power, mileage, timing control, consistency, cold starting, hot starting, response, consistency at altitude, etc. It's a matter of individual use and interest. If you're concerned about originality, it's not going to be worth it. If you aren't, everything being "hacked up" is already disposable on a car like this.
We don't know for sure. The original carbs were in such terrible shape that it feels like it gained over 20hp, but that could be specific to this car. It definitely starts and runs a million times better and is way more reliable after sitting.
@@AmbiVe certainly two into six never made much sense to me from a carburation point of view. My 240Z was night and day after swapping the two SU-type carbs for triple Dellortos, but they took ages to set up well; these days I would go for a 3rd party ITB EFI system every time.
All the prices were pre-COVID. The EFI system was about $2000, but there's a lot there that you could do differently or save money on if needed. The kit makes things easier to ensure you have plenty of parts. I would say that if you wanted to use nice fittings and rework the supplied wiring harness to be the correct length with A bulkhead connector, probably $2500 because fittings are expensive. If you had someone else do the work, the hours would be pretty spendy if you didn't just do a simple install.
Hi - I am currently thinking about installing EFI to my TR6 and like your setup! The only part I can't get my head round is the Distributor! What system and installation setup are you using to link the Dizzy to the ECU? I am currently faced with a Crank mounted timing wheel and sensor which I don't really want to do....
I used the retrofit kit included with the EFI kit for the TR. For my 280Z I used a Bluetooth programmable unit that allowed me to create my own curves on rpm and vacuum, and on my other cars I have used timing wheels. It all depends what kind of control you want. These TR engines are basically agriculture equipment so it's unlikely you need as much control as say my 450hp 240Z, so I'd keep it simple.
