M50 Swap: How much did you spend? How much should I budget?

[trent]

yes, as am I. I am pretty proud of my m50 though. I like the 260 trans because of the overdriven 5th (i run a 3.25lsd). Yes, i know that the zf 250 was 1:1 and thats where the m50 should be with a 3.15 or 3.23 diff. But im around 2500 rpm at 75. I like reving low for some reason, damn eta. but its good on the highway.

I was about even with an e36 m3 from 75 til we shut down around 115. I cant confirm it was an s50 or 52. hopped up e46 put about 7 cars on me from 80 up though.

d00d you need at least a 3.73

my roomates e30m50 has the 3.73. Ill admit it feels much faster out of the gate and it gets into the rpm quicker. Maybe its due to the fact that his car has more wheelspin, but I can pull away from his car everytime from a dead stop. I really dont have anymore power adders besides those ebay headers.

only thing i dont like about the 3.25 is it seems like it takes forever to get to the m50's sweet spot right around 3500 and up.

not too concerned cause its the daily and i can still squeeze 28 mpg out of it.

i was going to go with a 3.25 but what cars had the 3.73?

Just about every E30 that had a limited slip. ;)

Every 325i with a manual transmission has a 3.73. Some are limited slip.
