I know this is a jag forum, but since we’re all friends here and we’ve all put our heads together in the past, I was wondering if anyone out there would like to weigh in on my TR6 FI project that I’ve been cobbling together.
The TR6 is so simple, but I could go for better fuel economy, especially with such a tiny gas tank and rising gas prices. I had been driving around with the dual carb ZS175 system for the past year, but I think I’ve found a better way.
There is an existing TBI conversion for the car, using the mid80s GM style low flow TBI injectors. I wanted to upgrade to modern port style injectors, but feed the car as if it were a TBI. Another gentleman has done this approach, only he uses two injectors per carb, which is a cramped fit. He did this because of fuel leaning issues.
His injectors are 15#; my thought was I could upgrade to say 42# or 60# injectors to compensate for this. For a while I thought two LT1 injectors might be good enough, but they are only 24# and I’m not sure if I would run into leaning issues.
What are your thoughts? I already have the fuel delivery system jigged up, along with the electronics, etc. If I could reduce the setup to have just 2 injectors, it frees up alot of space in the carb bowl for injector mounting… and I can make the setup more simple and totally reversible!
Any input would be appreciated!
