LSD for 2.7i swap - Got One!

[Andy.B]

My 87 eta is getting a 885 head and motronic 1.3 swap, and I'm looking to get an lsd to replace the 2.93 open diff it currently has. I daily drive and autocross the car, and could definitely benefit from better acceleration, but I don't want to go too high, and have to wring the engine out on the thruway.
I am located in western NY, zip code 14043.

Let me know what you have, and how much you want to ship the diff to me.

I got a 3.25 lsd from a fellow r3ver for $230 shipped. Thanks guys.

I have a 3.91 vlsd. Perfect ratio for a n/a m20 IMO. Locks up good. Low mileage no noises. $250 shipped.

My understanding is:
Eta 2.79-> 3.25 is ideal
I is 3.73 is ideal
M10/m42/s14 is 4.10 is ideal

I am worried that 3.91 would be too high for a budget 2.7i motor. Am I wrong in thinking I want something in the 3.25 to 3.73 range?

Snagged a 3.25 lsd from an e28. Thanks guys.
