hey guys i was lookking to do a sr20det swap in september when i get back to school (i am in high school) so i have a shop to do the swap in. im in grade 12 i have a nissan 240sx s13 i was wondering what i need to buy other than the motor tranny and harness, i know i need a BOV and innercooler/ piping but what other small things would i need? i am also doing the swap myself and am aware i need to modify the harness, i have plenty of skill i am in the specialist high skill major and have gone to the ontario skills competition so i know enough about car to do the swap myself. thanks

There are many threads on this but you don’t needa BOV, but i would suggest replacing the clutch and resurfacing the flywheel. Get a walboro 255 fuel pump. You just need to switch some wires around the ecu if you have the SR harness. _Clean engine bay before installing motor_ An often missed step that is much harder with a motor in there lol.

if you dont have a blow off valve where does all the boost go when u let off the throttle and wouldnt you get a shit load of turbo lag?

right.  
i guess he meant that you dont -need- a bov in the first step. it will work without it.  
dont know how “complete” your swap is, but the SR20DET has already a BOV, but a closed one.
