As Bluprint said it all bolts in easy,R32 motor and 5speed went straight into my Oz R31 with no welding grinding,it was just like putting a Rb30e in but the RB20det looks more sexy :headspin:
Dori I gather your R31 is oz and if it is the R32 gearbox will bolt up,I'm not sure about imports thou
Plus the Rb20det sounds so much better than the SR20 :aroused:
