Hello, I'm on the point to finalise my S2000 Turbo project, which should be giving out more than 500HP once finalised. At this level of power, I do not think the stock differential will sustain a very long time.

SO now, I am asking the expert on the site, what solutions are available to reinforce the differential. Can some of you explain what you have done on your cars or what you would recommend? I have seen kits to reinforce the stock differential, I've seen complete replacement kits and even to put other cars diff on it to make it more solid (like the Nissan).

Any information would greatly be appreciated and thanks. Mike

 

search puddy mod diff, he is the man with diffs

 

talk to puddydad, also upgrade ur lsd.

 

for a quote from puddydaddy "Nothing will hold up forever" it all depends on how you drive and what you intend to do with it. You want to go launching the shit out of your car? guess what, our tiny differentials just dont cut it. The r200 (90 300zx) diff holds up well for that, but its something around 5k for that setup alone... puddydaddy can build you one if you'd like, and i like the guy, he knows what he is doing, talk to him. but again... it only lasts as well as you treat it!

 

Ford 9 inch.

 

lol

 

Local guy is running stock diff with around 500hp. He told me he just doesn't drop it much.

 

Nissan r200..

 

Regardless of what anyone tells you, the nissan r200, my preferred path once i get there, as i already have the diff, is a monster. I've seen em rebuilt (s2k from hell) and run 700+ whp on 7k+ launches over and over endlessly. Plus, some of the NA converted to turbos hold em pretty high aswell for the stock 300zx's the diff comes from. if you have the money, get it. if not, get one from puddy, and dont launch it like a numbnutt.

 

Cheaper option is the Comptech rear end.
OEM end with Comptech billet caps.
Swap onto your OEM pumpkin and go.
