Im sure someone else has said this already but...

you need a bigger feul pump. My friend Jr has an SR20det in his S13 and as we started to play with the boost it would not want to start like ti was supposed to and sputer a little....get a bigger feul pump and a new fuel filter and you will see a MARKED improvement on the idle, cruising, acceleration, and just flat out fastness...Before he put his pump on, i could pull on him like no bodies business, but then her got a better pump and a new filter and raised the boost like 2-3 psi and stayed at my door...
