November 18, 200916 yr like does the dump valve have to be made specifically for a 300zx or is a dump valve a universal thing?
November 18, 200916 yr there are ones specifically made for the 300zx. There are different ones kicking about depending on where your wanting to put them. i.e. on the hardpipes in the engine bay or in place of the stock recircs.
November 18, 200916 yr Nope.....no performance whatsoever until your running "silly" power. Wouldnt always look for the cheapest option as some can leak to rough idle and other sorts of problems.
