Can DSM 450 injectors fit a 00 Accord F23A4 motor ? If not, where can I get a hold of some bigger injectors ?

 

yes they can fit

 

Thanks. Do I need to make any kind of modification for them to fit and are 450 a decent increase ? Will my stock rail support them or am I wasting my time and money ?

 

the only thing you have to modify is the o-ring for the intake manifold - a dremel sander bit conveniently is the exact size you need. You will also need to change your injector clips to match the injectors, and with DSMs you will need a resistor box or in-line resistors. Your stock rail will bolt right to them.

Of course you also need some way to control these injectors, or your car won't run for **** - the stock ECU can't idle 450's, are you planning to boost?

 

I am planning to go turbo in the future, but for right now I am looking for any hp gain possible. I have the basics already, header, intake, plugs, wires, hi-flo cat and exhaust. I will look for dsm injectors with everything. Thanks for the help.

 

bigger injectors will not give you more horsepower, IMO don't waste your money until you need them. you'll have to run the AFC hack or a standalone to run them. your car won't even idle if you don't.

 

Do NOT put those DSM's in until you have some way to adjust them. Also the basic bolt ons do not necessitate the use of larger injectors.. your stock injectors can support what you have for now... when you decide to go turbo then put the larger injectors in and have a means of controlling them, i.e. Apexi V/SAFC or Greddy Emanage or AEM EMS or Hondata, etc
