My new car- 73 Opel GT

[opelgt73]

OGTS sells a modified (2.0L-2.4L) setup that is ready to install along with a non tested setup. If I remember correctly they were around $500 a few years ago.

OGTS sells the later model 2.0/2.2/2.4L FI setups that were used in later model Opels until about the mid 90's, so plenty are available in European junk yards. If you have any friends in Europe they could probably source these very cheep.

Or you can find a 1.9L setup yourself that was used in the 75' model year Opels. They're around, I've seen plenty of them. My preference would be to find the manifold used on the 75' setup and use newer components for everything else (air flow meter, injectors computer etc). I know you said you don't want to mess with a computer but programmable fuel injection computers are very easy to setup and you can setup multiple fuel maps for economy or power etc.

For the 1.9L setup just put a posting on opelgt.com that you are looking for one.
