Guys,

Further to my post on my Turbo issue, I found this on the forum site so now I know what the N75 valve is My next question is do I upgrade or go OE? Benefits to both please if you would be so kind and approx cost and suppliers.

As before, my car is 02 VRS and standard with approx 73000 FSH.

There are several different N75's available, but I'd advise you to stick with the standard OEM C or F valve

C or F??

The letter is a post fix on the part number stamped on the N75. You should have a C on your car but that has been replaced by the F valve. There are also J & H, which produce a steeper spike, but I'd steer clear of those on a standard car.
