This was in another thread, so i started a new topic to fully discuss the mod/experiment. :)
The thing is that i am tired of the Keihin carb, so i will install a complete fuel inyection system in the car.
Mono port inyection or throttle body inyection will be adapted from another car, in this case a Renault R-19 1.6.
WARNING: This is an experiment, and i am doing it knowing the danger of working with a high pressure fuel system, and this thread is for sharing ideas, and not intended to be a guide or something alike. I dont encourage anyone to do this mod, since i dont really know if the experiment will be sucessful.
Anyways, there are some kits to go from carb to EFI but those are proven, well designed kits, engineered especifically for some models, and not an adaptation from another car:

Yes, it is TBI; some Civics from the late 1980s have a similar system (but I think with two injectors in the throttle body). I saw them in the junkyard.
The O2 sensor goes straight in the exhaust mani BEFORE the cat converter.
1G: why TBI from a R-19? It is a bolt-on where the carburetor sits? Are VWs more common over there, or it is easier to adapt the one you got than one from a VW? Just curious.
TBI was the GM denomination for this system, but every brand named it diferently (Ford CFI, Volkswagen MPI)
I wanted to use a Volkswagen Gol 1.6 inyection system, since this is a common car here, but after some research, i found out that the trottle bore is bigger in the Renault 19 1.6, and big bore to me is = big power, so i chosen the R-19 one.
To perform this i will need an adapter plate OR to change slightly the position of 2 of the manifold studs and create a bigger bore on the intake manifold.
Mods needed in the engine: A place for the pinging sensor and crank/cam position sensor, a piece of exhaust with the correct sensor before the cat, and a temerature sensor for the ECM.
Parts needed: ECM, wiring harness from the donor car, O2 sensor, pinging sensor, MAP sensor, temp sensor, external high pressure fuel pump, filter and lines (maybe i can use the original ones) and inyection body (with inyector, built-in TPS, air temp sensor,fuel pressure regulator and idle control actuator.).
So far i have bought the ECM and harness, inyection body and O2 sensor, so i can start working.
