standard injectors are just short of 10.9mm rc's go straight if you use the injector dynamics 11mm top hat youll have to bore your rail out

I got an injector service kit off eBay and the tophats were too small for my blitz/Denso injectors. I got some that fit from a specialist called af tuning in chesterfield.
