Final verdict? Es - sx diff?

[atcmatt]

So guys whats the final verdict on the 250sx differential swap into the 250es? I have the money to buy a sx diff finally and i wanna know if its worth me buying it and getting it shipped over here.
Will a 1985 sx diff bolt into a 1985es.
Whats the go? Will it just get me a better top speed? I feel like my es winda out to fast on open roads. Also, will 1st gear still have plenty of stump pulling power? John swinehart, please chime in, i remember talking to you about this a long time ago but cannot remember where our conversation ended.

Thanks fellas. Matt
