OEM fuel injection on a GT

[kndlindsey]

Can you use the fuel injection parts from a 1975 opel 1900 engine on a gt? And do you need a specific exhaust manifold or will the standard one work?

you can use just the manifold itself, the rest of the piping is no good for a GT. if you had a Manta or an Ascona, you're good to go

If you install the Bosch L Jetronic EFI from a '75 Opel in a GT (or earlier Ascona/Manta/Kadett), you either need the "Sprint" manifold that comes with the Opel EFI (as per the eBay listing) or a header. The standard pre-'75 carb'd style exhaust manifold has an open flange that bolts up to the base of the carb inlet manifold to apply heat to its base. Since you don't have a carb'd inlet manifold, you need an exhaust manifold without the opening.

There are several threads that discuss the issues of installing the OEM EFI in a GT on this Forum. It is NOT a simple bolt up, as you need the entire harness and computer, all the relays, the high pressure fuel pump, and a return line to the tank. A '73 GT tank is also recommended, as it has a return port already (for the vapour return line from the '73 fuel filter). There is also some minor modifications required to the bodywork.

I put the euro inj on the mistress as the wife calls it, about 12 hours of fitting , refitting running line changing fuel tank putting in elec fuel pump mounting the ecu and some slight body changes. I got the unit from OTGS it comes with some instruction and alit of photo for the changes.I would not go back to a carb

Probably better to get a complete 2.0L set-up from OGTS - later model (1979 onwards). There are all sorts of little bits and pieces needed and getting a known, complete system from OGTS is probably cheaper n the long run.
