After making a couple of upgrades (1.75 stainless exhaust manifold back with 4 inch tips and custom air intake). I have a unusual question I'm sure you'll all laugh at. Is it possible to fit 1.5 Terios injectors (~105 bhp) and rail to my 1.3 Copen and would it make any difference? Or have long gone the days of old 1.3 escorts where I could put in 1.6 injectors for increased performance?
