And another M30 swap begins

[yert315]

3.73 over a 2.93 ANY day. I am running a 2.93 right now because the 3.73 I had in blew up after a mile (Check your gear oil!!!). But for the mile I had it in, it was much more user friendly.

And a 3.73 will likely increase gas mileage, contrary to what many people think. Running a 2.93 takes more gas to get the car going and maintaining speed. The only time a 2.93 would be sufficient is if you have 300+ HP or you travel ridiculous miles on the freeway. Even then a 3.25 would better suit the car/motor.

Is a 3.73 lsd all that bad cause i have 2 options that i see all the time at the local junk yard nd thats the 3.73 nd the 2.93 just trying to figure out what would u guys suggest to be the best option

I think mine had that plate - you could check my project thread. I'm sure I trashed it.

will do george graves will do

I know it´s worlds apart probably, but must one install the LSD when doing this swap? I mean, is it mandatory? I´m still collecting parts and this is drying my bank account like crazy.
E30Beast, what kind of engine did you have in it?

hahahaha talk about drying your bank account lol bcause im in that same situation nd its not in the car yet but hopefully pretty soon but its a 91 b35

[E30 Beast]

I don't think I have that plate. Only problem I'm having is some rattling noises at idle up to about 1200rpm

man if thats all it that goes wrong i can deal with that, i thought it was something major

Well, unless you like spinning one wheel then it's not mandatory ;)

Seriously though, depends on what you will be doing with the car... it's not like open diff will prevent you from driving a car, but having an open diff in a FWD or RWD car with lots of hp/tq = not fun.

[RickSloan]

i just finished a 1200 mile trip with my 3.25 gears and it was a joy on the highway.

and yes you need that sheet metal.

[flawdaboi407]

I have a 2.93 and its way to long for my liking. 40 in 1st , 75 in 2nd :) hondas dont like me cause they have to shift and by then im gone hahahhaha

[Doughnut]

Yep. I think 3.25 or 3.46 is the most ideal. Not tall and not short.

I have a 3.46 lsd in my m30 swaped e30 and find it to be alittle short. Though I do have the G265...

[E30 Beast]

hey jean i was talking about that piece of sheet metal that goes half way around the back end of the flywheel
