in addition to that: axles (abs or non according to your car)
wiring harness
the 2 water sensors (back left side intake manifold)
tps
cross member (easier to get one out of an ser than retrofit your ga one)
accessories (i.e. alt, a/c if you want it, p/s, h2o pump)
o2 sensor
and thats all i've "discovered" so far. i'm putting a JDM sr20 in a 94 GA16de sentra. the sensors are crutial because JDM uses different voltage sensors than USDM. oh yeah, MAF. also, this is for a N/A motor, i don't know about the BB turbo....but all this should be the same. misc. hoses, etc...hope this helps. if i find anything else i'll let you know, and please do the same! i don't want to miss anything! thanks, Mike
