I'm currently trying to build my 93wrx up.
is a parrallel fuel rails mod worth doing on my V1??
I know off a set alloy fuel rails for sale, do they fit all classics or are they made to the the versions? i.e v1-4 and v5-6

 

What set have you been looking at....

CDF Racing do a kit to convert side feed's to top feed parrallel fuel rails, this allows you to put 550cc injecotrs (or what ever) into your V1.

Top feed injectors are cheaper and easier to get hold of (Which is why i went this route)

If you are looking at fuel rails from anything newer then a classic, I have a conversion for sale, which will allow you to fit newer fuel rails onto a classic:
