New 2.8 Liter Six for the Racecar, I'll be asking a bunch of Conversion Questions Options

[motorvated]

The first question I have is related to modifications to the engine shelf pieces required for the 6-cylinder conversion. I noticed the Patrick Motorsports sells an expensive engine shelf kit for the 6-cylinder conversion. But, since the 6-cylinder is going into a Racecar, can I just cut out the entire engine shelf to maximize the available space in the engine compartment? Or, has anyone made a template that can be used to modify the 4-cylinder engine shelf to accommodate the 911 engines? I'd like just to remove the shelf parts if they are not needed. Thoughts on this? How do you other racers handle this. Many more questions to follow. I know there are many conversion threads out there, but it's hard to weed through them to see if they address the question(s) that I have. Plus most of Tigre are for street car conversions, not race cars.

My -4 has FAT 911 fan shroud with no additional tin and a shrouded rx7 cooler up front, engine shelves on chassis remain in place.

My -6 is more of DE/track than street, but I do take it on the street still, but I run fiberglass engine tin. I have a non shrouded cooler up front with dual fans.

Both run 180-210 on 110 degree track days.

I have an Electromotive crankfire ignition, on the dual plug 6. Old tech, but seems to be easy to tune once installed correctly…
