[sd2nola]

i have an sr20det red top motor and it has a hard time starting and ideling. It also shakes kinda bad too. Any ideas? do i need a bigger fuel pump or is it something else?

Thanks...

There's usually more to it than just a fuel pump. How's the timing and the fuel injectors? Did you change the engine mounts while the engine was out?

Although I would still suggest changing fuel pumps regardless of how much boost you're running since your old one was probably a few years past its prime anyway.
