C109 OIL FILTER and 10w-50w fully synthetic oil is the general recommendation

Larger Turbos such as hybrid units, Cosworth T3 turbo? s or T28 turbo? s can be fitted. These will all have different Powerband characteristics. I have tried a t3 on a standard engine and found it had a bigger power band slightly higher in the rpm range

where can you get these oil filters from and whats the difference with an oe one. and with the turbos, will the t28 bold on to the std manifold??

Halfords or any motorfactors will have those oil filters and the t28 will bolt straight onto the standard manifold

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 · #8 15-11-2006, 23:56

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

Is there a fuel pump available of another car which can be used instead of a wahlbro? ie a skyline one or something?

ive heard of people using a 300zx pump, it should do the job as they are 280bhp as std and i bet you can tune them a bit before you have to change the pump.
