2LV8ETR Posted April 11, 2009 Share Posted April 11, 2009 A 20/30???? Depending on how many ponies your pushing out will determine which box to use. An RB20DET box is okay, but if you put too much stress on her, she'll shit her pants. An RB25DET box will take a lot more power and is a better option, but you will need to convert the speedometer drive to a cable type as the R33 uses an electronic pulse sensor. As for installation, do it yourself.

bubba Posted April 17, 2009 Share Posted April 17, 2009 I killed an RB20 box with only 183rwkw out of my 25/30. For a 25 box conversion, you're looking at 2.5k just in parts so if you can do it yourself it's a lot cheaper Link to comment https://www.sau.com.au/forums/topic/265080-what-gearbox-should-i-use-in-a-r32-4-door-w-rb2030/#findComment-4539561 Share on other sites More sharing options...
