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.

Depending on where you want to drive the car be careful about what you cut out. Many vintage groups will not let you run with the trunk cut for example. Read the rules of where you want to race if that is your goal.

You should also consider the stock location and style for the oil tank. I have run in the front as well on a conversion car I owned in the past.
