M3 vs non-m rear

My friend is planning to do a e30 rear-end swap into his opel manta, I don't know much about E30s so I thought this would be the best place to ask.

He wants the rear to reliably 250whp and 300+wtq, now could the non-m accomplish this or would he need the M rear end. What are the significant differences between the M and non-M rear ends.

I've seen 4lug e30's with well over 800hp.

I think it will be OK.

Only differences are brakes, 5 lug hubs, and different gearing.

A non M3 and a regular 6cyl E30 rear end should work. I have seen 4 lug cars with over 1000hp, so no need for the 5 lug if you have a 4 lug avail.
