Quick S13 differential question

I found this article about putting a z32 differential in a 240sx. I learned that the differential that na z32, s13 and s14 use r200 differentials. Also, I saw that Twin turbo z32s use R230 Differentials. So my question is, is it possible to install a R230 differential in a s13 chassis? let me know thanks

Pretty sure the answer is no.
R230 diff is too big for our sub-frame, it wont bolt up..And even if it did i believe you would need a new drive shaft.

I've heard of people doing it with heavy modification. It doesn't seem worth it when the R200 is easy to come by and a great diff

sounds good. I have all the parts already with me and are ready to be installed. in order to do a q45 differential upgrade, the last thing is buying the right q45 differential and there are 3 different ones. here is a link with pictures of what I have so far except the q45 differential.

Last question, do any of you guys have any preference between any of these 3 q45 differentials?

1990 - 1996 Q45 - G50 - R200V - 3.538
1997 - 2001 Q45 - FY33 - R200V - 3.692
2002 - 2006 Q45 - F50 - R200V - 3.130

The thing is that in my KA24det I am pushing 450HP and I am using the S13 - KA24DE - 4.083 R200V differential and I guess I am interested in getting a q45 differential because I want to get a better mpg and lower my rpms. I know it will make my car slower if I upgrade to a q45 differential but I don't mind because I have a z32 tt 5 speed transmission in my ka24det and if I get the q45 diff. then I won't be burning out my tires on every gear as I floor the gas pedal all the way. Anyways let me know which q45 differential do you guys recommend me to install in my s13. This s13 vlsd makes my car burn out on every gear on 285/45/ 17 sport tires. I don't get why I still do not have grip when I floor it.

Honestly if your always smokin tires & shit any old vlsd is gona eventually give out on you especially if your pushin 450hp. I know it may be a little more but you should atleast consider getting a used KAAZ or CUSCO Diff. In my personal experience z32 or Q45 diffs are only dependable for accasional rain fun.

I see and the kaaz LSD has the same final gear like the q45? I am trying to make make my car get more mpg too.
