Default Larger injectors + higher boost pulley = problem?

I was wondering if I could swap out the pulley for a a higher boost pulley (9psi?) and get larger injectors (RC550?) would it be somewhat safe? I also heard that you need to get a different head gasket...what one should I be looking at? I want to get some more horsies under the hood, but I don't know if I can afford cams, pistons, etc. Please enlighten me on any other routes or any info relating to my questions. Thanks!

-Matt

Add an AEM computer and some dyno time and you should be fine.

I dont think you need a different head gasket. You should be safe with the stock one at 9 psi.

thanks for the link! I am running somewhere between 7-8psi.

How much rwhp should I gain with a 9psi pulley, aem ems, rc550 injectors, and godzilla bov?
