thansk guys

 

Intank should be fine. You don't need the 100+ psi fuel pressure to push 450ccs

 

I'm pretty sure one of the key features of the SMC is being able to use larger injectors without upgrading your fuel pump, so you should be okay.

 

You don't need a new pump, but I used a stock DSM turbo pump in my car. Usually the guy that your buying the DSM 450s from will also have his stock pump laying around so you can ask him to give you that too. Its a direct plug in for 5G civics.

 

so all i need it smc and 450cc with stock intank

 

Yup, that will work fine. Don't forget the resistor box!!

 

its in a crx any speacial stuff i need

 

anybody body know the max boost u could run on the smc and 450cc injectors without a upgraded fuel pump.

Being particular to my setup I also gonna have a 3" exhaust and 2.5" downpipe and i'm guessing that will flow better meaning more fuel will be needed.

 

Each car is a little different, my guess would be 9-10 psi
