allow me to correct myself...

i meant an rb20det, as found in the japanese (and other right hand drive countries) 200zr. the rb30e was found in the commodor and can have the rb25 or 26 head swapped onto it, depending on your turboing desires. the rb20det was a i-6 2.0 liter, with @214 hp at the wheels and all the potential of it`s offspring (rb series motors) and i just read on the www that an rb30 will bolt right into an s14 with an r32 crossmember, jfyi.

also there was a 300zr, but it had a vg30xxxx motor

pic is an rb20det in a 200zr

vg30dett is the engine code for 90-96 300zx, 84-89 (which is what i have) is a det.
