I have a 1984 Celica with a 22RE engine and I'm wanting to put 20% over stock fuel injectors in it but the only ones I can find are generic and I have to build a custom fuel rail to make them fit.I was thinking about installing 2 cold fuel injectors down from the throttle body to get the extra horses I'm looking for.I know this will work but will the cold fuel injectors get too hot running all the time?
