New to Z cars....please be patient! I need info on the strength and available gear ratios for R180 and R200 rearends. I just bought a 72 240 and have not yet acquired any manuals. I wonder which gear ratio my car may have. If I put a V-8 in this car, will the R180 hold up? Which rearend would be the best choice? Thanks for your input......Bob

Here is something you might find useful:

Probably not. There are plenty of parts on the Z that need
to be modified to handle a V8. (Although there are great
kits for these things... you can take a look at
www.jagsthatrun.com).

Some people use the R200 with a V8, and other people swap
that for something even heavier, but I don't think anybody
uses an R180. R180's aren't even supposed to hold up with
a hot L28 engine. (The 2.8 liter engine from the 280Z).

Also, keep in mind that a V8 Z isn't a Z anymore... I've read
that it really changes the way the car acts on the road. More
like a half-Z and half-Corvette when you're done.

It's really easy to swap a '81-83 L28 engine into a 240Z though.
That's what I have in mine, and it has more power than I'd
ever want to use. (But then again, I'm not a fast driver)

Here are some other sites that you might find interesting:

www.240z.org
www.geocities.com/MotorCity/2824
www.zhome.com

I recommend the Haynes manual too. (altough any of them
are prefectly good.) I just use it and think it's okay.
