My suggestion is to just purchase a used SE-R (B13 Sentra, B14 200sx) and do the DET swap there. Would probably save you time with axles, harnesses, blah blah blah. A DET swap can and has been done into some originally GA-motored Sentras and 200's, but I believe extra time and work was spent making the hybrid work efficiently. My .02
If you opt to do a full 1.6 to 2.0 DET hybrid, please keep us informed!!!
