suppose so on the glanza S the difference between our engines and the 99bhp engine is all ecu though, not the engines. compression ratios are the same. everything the 1st gen engine came with, i had in mine and same as raffa. his made 90/91 (cant remember exact figure) only difference being ecu. so with out the ecu, you arent going to get 99bhp whichever gen engine you put in there. and raffa was running standard uk spec injectors where as i was using corolla injectors (again my engine was being drowned by the FPR being set way to high at 4efte pressure
