            Do you know anything about pricing Markus, for a crank and rods.
            Are pistons needed?

                    the calculation the dutch add is incorrect B X S=93.4 X 91> 2494 cc[done]
                    95 X 91> 2580 cc

                    Great car Sven

                      are those the clutch and brake pedals? if so, how do you heel-toe?

                      or are they the brake and gas? if so, why are they both on the left side of the steering column?

                        I don't think you have to heel-toe with a sequential gearbox.

                        Do not buy from "Low Level"!

                          A competent machine shop can offset grind a 2.5L crank which would make the rod journals smaller meaning custom rods/pistons. I am sure you guys are building these big motors with custom long rods/pistons anyway to overcome extreme rod ratios.

                          Another good plus is a smaller rod journal means less friction and more power! Mechanical advantage rules.

                              In a sequential box you only need the cluch to start the car . so there is no need for heel-toe.
