Lockyb123 Posted April 23, 2018 Share Posted April 23, 2018 Hey guys im swapping my n/a S1 rb25de to a series 2 Rb25det and i was just wondering what things will i need to make it a straight swap e.g will it bolt straight onto my gearbox and will the engine mounts be the same cheers Link to comment https://www.sau.com.au/forums/topic/473850-r33-s1-rb25de-conversion-to-rb25det-s2/ Share on other sites More sharing options...
GTSBoy Posted April 23, 2018 Share Posted April 23, 2018 It will bolt to gearbag and mounts. It will destroy the gearbag if you use any of the turbo's extra performance. There are many electrical differences. Best bet is to take the whole engine/ECU loom and be prepared for annoying differences in the peripheral electrical connections (like maybe the alternator wiring, air-con, etc).
