Inliners International Forums General Discussion Engines GM 4 cylinders 151 153 181

Using a Google translator line by line it seems that these were developed in the late 80's in Brazil to compete with the Cosworth Fords and Porsches, etc. on the rally circuit. I'm not sure hfow many were made, I wonder if Douglas Carbonna knows anything about them? Portugese is close to spanish but there are a lot of differences. I found it searching for "4 cilindros Opala"
