Bige in my eyes locked dizzie is done and proven no need for complicated ecu or electronics.

A12T or A13T well tuned with 80 to 145hp atw using drawthrough setup is all thats needed for our light little jiggas. Beyond 150hp then EFI and strengthening measures are needed to withstand beyond 200% original output they are designed for.

Gearboxes also become and issue all costs then skyrocket even with a big hp NA A series gearbox choices are oftern overlooked as they are pigs to drive on the street. With 80-145hp atw stok 4 speeds are good enough with a decent clamping clutch. The torque they produce dont require close ratios saving a big wad.

eg. a12 69hp -> 120hp ate, a13 75hp -> 150hp ate, a14/15 80hp -> 160hp ate

For me the torque that turbos produce is much more appealing than hp.
