Consistent with forum rules, I feel that it would be unfair to try to post facts and not let the vendor rebut.
So this post is based entirely on how I feel, and has no basis on facts. This line of posting is consistent with the forum rules so please pardon me.
I personally would not do business with this vendor again.
Anyone trying to buy this or another R200 with 3.3 ratio would be wise to ask for evidence that the ratio is indeed 3.3. You would also be wise to ask for a measurement of the snout and compare the measurements with your own S-chassis snout.
Just because the item says "S14", that doesn't necessarily mean the diff will physically bolt into an S14 without at least some work.
FYI, no Nissan OEM R200 ring and pinion ever left the factory with a 3.3 ratio. Anybody who claims to know to the contrary would be wise to furnish proof.
Buyer beware, and if you have any problem call the seller immediately for response and follow up with emails to confirm what was agreed. Save all the papertrail for use later.
