10psi. After that the inlet temps rise too much and kill any benefits of increasing the boost and so this levels the power out. Fit an intercooler and then you can winde this up by an extra 4psi with a very healthy standard Turbo.

Sorry if this is a stupid question ..doh! but what is a C109 oil filter ?Is that a Fram/Nissan part number and does it have bigger capacity than std. filter ?

[30psi]

Thats a champion oil filter which is an alternative supplier. Its identical to the Nissan item. Halfords stock these

Thanks I'll try Halfords if my motor factor doesn't come up with anything
