Default What size pulley for vortech and where?

I want to go up in boost but with a non-built motor. I'm planning to get rc 650cc, walbro 255 fuel pump, and maybe hondata s300? I'm running stock headers, custom tp, and ap2 exhaust.

What size pulley should i run and where should i get it from? Also is running hondata s300 good or should i go aem or ultimate? I only want like 350-400whp.

What size is it now and how much boost are you seeing?

ASP in Texas makes a good pulley. http://www.aspracing.com/index.html

A 4.5 inch pulley would be a good starting point.

I just got a 4" ASP pulley for 12 psi which should get me near 400whp I would think.
I would get some Injector dynamic injectors instead of the RC injectors as they are known to run much worse.

New injectors 750s or 1000s, new 3 bar map sensor, new pulley 3.8 inch, new belt 4060495, new EMS (AEM EMS recommended,) new tune come to mind. Read the stickies at the top of this forum.
