Torsen swap now or save for OS Giken?
 

I have another question for the racing experts. My NB is a base with open Diff. I'm wondering what others think of my following logic.

I want an LSD, but think I would benefit from learning the cars characteristics first with an LSD. I know I won't go faster, but that isn't my goal right now. I want to learn to feel the car and improve my driving skills. So, I was thinking to add the LSD later this year. Does that sound like a good plan or will running an open diff not benefit me much?

The second thing is that I look at the price of the '99+ Torsen's with the 4.33 gearing and think it makes more sense to just pay a little more and buy the OS Giken. I also would like to add boost in a year or two (hence becoming a fan of mt.net) and think the OSG is the stronger LSD. After I boost it, would it then be smarter to move the OSG to another used axle or just replace the gearing?

Thanks for the advice in advance!

if your boosting and can wait...save for the OSG diff and do 3.9 gears. 4.3 is super short and sucks dick... even on a 5 speed.

I personally wouldn't spend the money on an OS Giken for the street. If you are planning on tracking it, then yes I would save for the OS Giken, but expect to spend another $200-350 to have it installed in your carrier.

BTW you can install a torsen from a 94-97 with a 4.1 as well and they are cheaper than the 99+. You only need the carrier and not the axles/driveshaft. Those can be picked up for $400-$450 pretty regularly. Most of the expensive 4.3 swaps you see are for diff/axles/driveshaft and are priced around $900-$1200.

I am actually about to sell a 4.1 LSD if you are interested. I need a 4.3 for my spec car.

Thanks! Keep me in mind, I may go that route. Is stepping down to a 4.1 while still bone stock '00 1.8L a noticeable difference? I'm already sad that my Diesel wagon can out pull my miata on a straight. I want to be able to get around someone if I get a point bye.
