The Rally Knight/Leading Edge kit I am getting at this time is rated at 300HP, and approximately the same amount of torque. It requires no internal engine modifications.
It will utilize either a Haltec E6K or Motec M4 (not 100% sure on the exact Motec model) ECU. In CARB legal trim, both of these ECU's will be modified from their manufacturers to prohibit end user reprogrammability, to satisfy CARB regulations.
I am opting to go with the Motec since I feel I will, at some point in the future, want to upgrade to Rally Knight's pending 450HP CARB package, which is only available with the Motec ECU. It's $1K more expensive (based on what I know currently, I'll be talking to Jon tomorrow after he's talked with Leading Edge about prices) than the Haltec kit at the 300HP level, but will allow more flexibility in controlling other features, and in data logging capability.
At this time, I am torn between going with the Rally Knight developed 4EAT or sourcing a set of dog gears from either MRT in Australia or from Guard Transmission in Hawaii. Bith have their advantages and drawbacks. For now, I think I will have to baby the transmission once I get the car back in turbo form, until things are decided on the transmission. The 4EAT has a lot going for it if it can solve the problem of the fragile Subaru manual gearbox.
What else would you like to know?
