I am currently trying to set up a group buy on Wolfkatz fuel rails on the GT4OC, and thought I should open it up to you guys seeing as we use the same engines and all!!!

I don't have a fixed price yet as I don't know confirmed numbers, but the more people involved will surely mean bigger discounts, so let me know who's interested and which rev MR2 it's for.

AFAIK the main advantage is for the Rev2 which has shown to run fuel pressure differences between cylinders 1 and 4 when larger injectors and bigger fuel pumps are used to run more boost, and the Wolfkatz rail is a bolt on upgrade that will resolve this problem completely.

So get your names down if interested.
