I'm running a hybrid just like you are asking about. You have to change the entire cluster. So like was mentioned.....R150F guts in R151F case. Everything inside aside from the gear ratios is the same. Must be the early R150F from a 3.0 however.
1st and 2nd on a R151F might be good for crawling but it sucks on the street.
