First off I'm totally new to 240SX's and I have a question.
I'm looking to replace the ring and pinion in my 91 240SX and I'm having a hard time finding a place that sells them. Where are some places that sell R&P's for my car and what ratio's are available ? Are there other Nissan vehicles that use the same R&P that I could maybe find in a junk yard ? I'm looking for some steeper gears to help with acceleration but money is kinda tight so with that in mind.....do you ever see any used sets for sell ? I'm looking to buy some ASAP so any help would be greatly appreciated.

BTW.... any of you guys ever go to VIR ? I live only 20 mins from there and go there quite often. [/b]
If you're in a hurry you might want to grab up the set Chris is selling. Courtesy Parts (courtesyparts.com) still lists the 4.08, 4.36, and 4.63 gears, but who knows if they really have them, and they want almost $500 for a set. If you weren't in a hurry I would say watch ebay, or 240sx.org, but the used ones only come along every so often so it could be a wait. I've found a couple of sets on ebay for around $250 - $300.

Some of the other guys here might know better, but the 4.63s might be a little too low for a fast car at VIR; I was there last weekend and with 4.36s I was in the 5,700 - 5,800 rpm range at the end of the back straight, and I was still a good 6+ seconds off the leader's pace.

Good luck.
