Glanza s ecu is no better. Only 86bhp same as a uk starlet with corolla manifold. Early brown corolla injectors are a urban legend as both early corolla and our starlets have the same fuel pressure, as does the turbos. I have glanza s ecu, ep85 ecu 5efhe ecu, all manifolds and pink injectors. My advice, use corolla manifold and fit a 50mm throttlebody
