I bought a 4.11 but Im not sure if I want to use it or get a 3.90. The main reason is I dont race all that much and this car is daily driven. Is anyone using 4.11 gears with the first 280 5 speed on a daily driver? How is the freeway?

Please help me out.

RE: Im confused on 4.11

Hiya Adam,

Adam I'm no pro with this but this is what i know, If you want to have a daily driver I recommend you don't go with the 4.11 because this will slow down your top speed to about like 90mph? i'm not sure but it does cut down on your top speed, But if you wanna race it will get you from like 0-60 very fast:) a lot faster then a 3.9 that is, but if you want this as a commute car I recommend you stay with the 3.9:)
hope this helped your desicion some

RE: Im confused on 4.11

Is the trans from a 280Z, not a 280ZX? I have a gear chart in front of me.. with a 3.9 and a 280Z 5 speed, you get a final 5th gear ratio of 3.37 which is the same as 4th gear on a stock 240 (3.36 diff) With a 4.11 it will put the ratio up to 3.55, adding a couple hundred RPM's on the freeway. Depends what you're looking for I suppose, faster starts or smoother cruising.

Can't offer any first hand experience, I'm in the research and fix other problems first phase right now. Thinking about a '81/82 trans with a 4.11 ..

RE: Im confused on 4.11

I have the 4.11, early 5-sp in mine. To be honest the 3.90 is about optimum. The 4.11 makes first and second very twichy, kind of a handful in traffic. But I commute every day with it.
I may change to a later 5-speed this summer, after the Battle of the Imports day at the dragstrip in June, heh-heh.

I have hit [email protected] in 5th, 60mph is 3500.
