SWdiv has a 3l displacement limit. So, if I had the money, I could stuff a 2JZ from a late model Supra in and gain about 100 hp and still be legal. You can run turbos with a displacement limit of 1.76l. The unlimited class is SP but then you are required a fuel cell, fire system, and GT/Prod roll cage. Which are upgrades planned for the future anyway. But I got to due this in stages (or win the lottery).

I should have used the other car for the project. If only I knew then what I know now.
