14b Turbo

How much boost can a 14b turbo put out with a mechanical boost controller, stock fuel, etc. 12-13? or 13-14? or if i go with 550cc and the 190lph and apex safc

I would say 15 psi at the most on stock fuel mods. Keeping in mind that the more mods you do away from the fuel system the lower you may have to tune the boost.

But with proper fuel mods I think 17-18psi is about max efficiency for the 14b, anything over that is not going to make anymore power.

just curious, sorry im a noob but what are the proper fuel mods to attain around 17 psi?

Injectors, fuel pump and a way of controlling them ex. S-AFC or Dsmlink and depending on what size fuel pump you go with maybe an FPR
