Sydneykid, Glad I've got you stumped on this one, I was shocked aswell. I know I only put BP 98 in the tank, mixed in the correct proportions with Octane booster. The injectors have been in there since I bought the car, and the car was 100% stock when I bought it, so I'm confident that there are stock. I would agree that sizing the injetors to meet the application, but seeing as we're not even at 90% duty cycle then the stock injectors are working great.
I'm using the stock fuel pump as a lift to a 3litre surge tank, then a 910 Bosch pump into the Malpassi.
I have the Greddy plenum, 100mm throttle body, custom exhaust manifold, R34GTR intercooler, if that helps with any of your calculations;)
