Engine swap?

i have a 1986 nissan skyline with a stock standard RB30 engine thats blown...was wondering if i could put in a commodore executive VL standard engine in it??

i have heard there shouldn't be a problem but im worried about the wiring harness and computer :banghead: being converted....any ideas??

anything would be appreciated...thanks!

the 3LT vl holden motor is the nissan rb30 engine so there wont be any problem with it
