There are two version of VG30DE
1st version. 89 ~ 93 300ZXThis version is known for its bad injector. Experts claim that alchohol in gas speeds up the corrosion in the injector coil. This is a very expensive repair. Also, CAS sensor on this version of VG30DE is made by Mitsubishi. Problems are reported with crankshaft assembly which will make knocking sound
2nd version. 93 ~ up J30 and 94 and up 300zxThis version has the updated injectors. CAS is made my Hitachi and crankshaft assembly is revised.
General difference b/w the VG in J30 and 300zxAir intake and fuel lines.
I will suggect you get the 2nd version VG30DE.
