time to start a huge build (well huge to me)

I know this,
but we will see, he mentioned different motors that he had around the shop but I dont know,
a 4.1 would make it quicker, but would the high revs wear on the motor more?

well i suppose if you want to get all technical yes. a motor only has so many revolutions in it but the difference between a 373 and a 410 isnt really a big deal. an m20 can run all day long at high rpm if its healthy. youre talking 3-400 rpm difference at speed

if you dont know what youre talking about dont give advice. it just makes you look like a douche

I think I'll go with the 4.1 LSD, I think I'll have more fun in it

[SynSyx]

i asked this in the other diff thread, but would be '89 325i autotragic cabrio have a 4.10? and open or lsd?

[Rockinlittle325i]

I dont know what size it would be but it should be open,
the IS's have the LSD

[Kerrath]

Yeah, different sources say different things. If you're going by wikipedia, then yeah 87.

you really can't tell until you look at it. LSD was optional on almost all non-is cars

Off topic........ OP are you in North Carolina?

Back on topic. Blunt's first post was right, too much mis-information in those first 5 posts.

[Kerrath]

My bad, fixed my mis-information.

[rThor432]

Nah, you didnt but no worries. Everybody knows what you mean.

[yert315]

Hmm.. my car was at 3400 at 70mph. I know I had a 3.73 in there. Maybe my tach was off a bit? I am only stating from personal experience, but I guess that's not good enough.

anyway, to answer synsyx's question:
I just removed a 4.10LSD out of my auto 325i. Like the guys above said, LSD was an option on all models.

[Spinning Tires]

Every m20 car I've come across had either LSD or came with LSD and had burnt clutches. Guess it was a coincidence?

[Kerrath]

Nah, you didnt but no worries. Everybody knows what you mean.

What is still incorrect? I'd like to know so I can know better next time and so I can fix my mistake.

Guess so, because there were plenty of M20 cars with open diffs.
