Mini-L320 Posted November 17, 2013 Report Share Posted November 17, 2013 just as the title states. I have a 1989 nissan d21 4x4 (hardbody) nap-z 2.4 throttle body injected 5 speed manual. Cant find a header anywhere for it only from 1990+ but those have the ka24e. just wanna know if a 720 4x4 header will fit in my truck Quote Link to comment
datzenmike Posted November 17, 2013 Report Share Posted November 17, 2013 The pipes will fit the head no problem. There are some minor torsion bar differences between D-21 and the earlier 720. Have to ask. where will you place the O2 sensor? Quote Link to comment
Mini-L320 Posted November 18, 2013 Author Report Share Posted November 18, 2013 weld in a bung for the o2 sensor no biggie. I also heard that a ka24 header will work just the ports are a bit different but will flow the same Quote Link to comment
