the best way to understand the difference is to know what the code stands for.

The first 2 digits are the engines unique code. if 2 engines have the same two beginning letters, that means that most parts are compatable (SR20DE & SR16VE). If the first letter is the same, only some parts are compatable (QG18DE & QR25DE)

the second 2 digits represent the displacement in litres (VG30E=3.0L, KA24DE=2.4L)

after that:
D=dual overhead cam (SR20DE)
V=Varible valve lift (SR16VE)
i=fuel injected (GA16i)
E=Electronic fuel injection (VG30E)
S=Carberated (GA16DS)
T=Turbo (SR20DET)
TT=Twin Turbo (RB26DETT)

Thank You

That was a very helpful description:) . So the difference is that its a DOHC, instead of a SOHC, and it's twin you think the engine mounts are in the same place and it would fit right in?? and the transmission?
