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

 

im running a stock vortech setup so 5" pulley with stock crank at 7 psi.

 

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.

 

Hondata S300? You mean Hondata Kpro?

 

i also have a vortech sc on my car and its on the stock pulley.
i like to put a diffrent pulley for 14-15 psi , which size pulley i need?
and is it safe to run this boost on the vortech unit or i need to change a few things??

 

no one?

 

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.

 

i have a complete turbo kit from my last s2000 so i alraedy have aem , id 1000 , sos 3bar map and all the other necessary parts.
im just new to the vortech supercharger so thats why im asking.
3.8 pulley would be good for 14-15 psi?
i have to get a new belt?
and do i have to switch to fmic or i can just stay with the stock charge cooler if i use meth injection?
