in theory, could I buy this, rebuild it with stronger parts, and fit it to my RB25det? http://www.nengun.co.../item/x36960207 Aftermarket ECU to run it? (Apparrently the RE4R01A has its own seperate ecu anyway, so I'm guessing this would too?) http://en.wikipedia.org/wiki/RE5R01A The RE5R01A was a 5 speed automatic, that was fitted to; Nissan Cedric Nissan Gloria Nissan Skyline Nissan Laurel Its a 5 speed version of the RE4R01A that came out in the R33. I know I could get a rebuilt/strenthened 4N71B for less, but I would really like to try the 5 speed auto thing... Want to keep auto. Want more gears.
