Will 440cc injectors fit a my93 WRX JDM without messing with the fuel rail etc.
If so does upgrading the injectors in itself give a performance gain or is it just to match the mods you've got or intending to get?

Thanks

 

The injectors will fit in the Oem fuel rails with adapters (collars and O'rings) from Pavlo who posts on Snet These alone will unlikely give any performance gain as ideally a remap will be required. A scoobyecu is available from David Wallis or Pavlo but a customised version will be needed to complement the bigger injectors

Cheers
