Looking forward to seeing your new setup when it's all done. You should definitely look into seeing if anyone can repair the ecu.
I've been having some issues with some recent mods myself, I got a bunch of HKS gear, adjustable cam gears for the intake and exhaust, oil cooler, catch can and the racing induction kit. They couldn't get enough fuel into the car, was leaning out with the standard fuel system so I've since purchased HKS fuel rail with HKS 600cc injectors and bosch fuel pump with HKS fuel pressure regulator.
I also followed your advice on the redline and am getting some lightweight for the gearbox and diff, if you know the quantity I need approximately can you pm me please.
Looking forward to the next cruise!
