YAY, I spent some money

[MR 325]

Today was the day... I ordered a 3.25 Limited Slip rear differential for my car. I know most of you could care less but I am excited about it! It is shipping tomorrow and I should hopefully have it by Monday at the latest and I will get it in sometime next week. Sweet.

Just thought I would share.

Now just to get rid of that m20b27 and everything will be great ;)



hehe nice, 3.25 is a great upgrade

glad to hear you found one so quick. those are on the rarer side

Won't that make the car sloooow to accelerate. I would have thought a 3.73 or 3.64 at the most would be suitable for a 2.7.

I'm sticking with my 3.91 sport diff for my 2.8 conversion.

not considering the stock diff in an eta...what is it, 2.91? something along those lines... :roll:

[E30Adam]

Ohhh, didn't realise it was an ETA engine, that would explain it.
I heep forgetting about those as you don't generally get them in an E30 here in the UK

I think you should have gotten a 3,73 or a 4,11. I have a 2.7 and can still get it up to 140mph at 6000rpm. in germany a 3,25 would be a downgrade, and we can go as fast as we want, were you would think a 2,91 would be sorta good for top end. Im sure that the 3,25 will be better than the old rear diff though. the 3,25 is what came stock in my M3- i have the euro no overdrive(dogleg), and swapped it out for the 3,64 and feel that is not steepenough. every E30 in the states should have a 4,10 or a 4,27 in it if you ask me.

The eta came with a standard 2.79 diff or a 2.93 LSD I believe. I'd like to eventually step up to a 3.25 as well. I've heard of other eta owners going to the 3.46, but I hear it really sucks on the highway.

[Super Eta]

2.93 LSD was an option for 325 and 325e it was standard on the 325eS. :)

an ETA can't rev to 6000rpm!! :)

[mikeedler]

i guess that's true -im a dumb ass. but wait, my ETA revs to 6900(with some mods)and you guys cant drive 140mph there

[MR 325]

Well, my car has the base model open diff wqhich if probably the 2.79 ot whatever the hell that one is so this one will be a big upgrade but will still allow freeway cruising and won't create a pointless first gear. If I'm really not happy with it, I can always get a 3.73 from a 325is but I don't think I will be doing that.

And yes, it's an ETA, revs to 5200 with my chip. :)

[Super Eta]

if it can go up to 6k then it must be a super. :D
