it seems that from what i can find out about the greddy rails from nengun and greenline, there are 2 versions..
one is an 10.5mm, which is meant for the std plenum i assume, and the 2nd is an 11mm one, for the greddy plenum.. does this measurement relate to the height of the rail from the plenum (some sites seem to refer to it as a diameter), ie. the height of the spacers that are supplied in the kit?
phat, could you please measure the spacers in your kit for me? you got the 10.5mm one?
i am going to use 600cc Nismo GTR injectors
sorry for all the Q's!, i have checked through the documents i got with the plenum, but i can not read japanese and can only rely on what i can make out from the pictures. i am trying to get the instructions translated though
