Help identifying TZ frame

Came across this TZ frame, subframe, swinger and shock. Can you guys help identify what year or model this is from?
Wondering if this can be basis for an RZ500 engine? I've read some posts of enthusiasts fitting the V4s in 3MA models.

Thanks!

the 3MA TZR250 frame had detachable subframe, Looks like a 1991 3XV TZR250 frame

TZ is a 250 GP bike
TZR was the street bike 250
