[QUOTE=domdten,Jun 13 2007, 07:04 PM] so are you sayin that the diff is weak yet he needs to launch it at higher rpm's to let the tires spin..doesnt that mean that there is no traction and therefor you are just sitting there and not having a forward progression.

i don't drag my car, so im curious. i thought that it was better for you to launch at 3-4k so that you get good traction and get a better reaction time...

i guess i need to read up more on the S just in case i take it to the tracks...i know the S is more of a track car. so what are the do's and don'ts in the S?

Ckit - I think these straps break because of the impact when the slack comes out of the driveline and the tires don't break loose.

Red, how did you quote a post that was posted AFTER you wrote yours?!!!!

IIRC, the caps would flex and instead of spinning, it would trap / pin / scoot laterally instead of rotationally. Hence the flying diff pieces into the wall.

This very well could have happened to my diff, but the Comptech reinforcement prevented that. So the torque and shock was translated to the next vulnerable piece... in my case, maybe the pinion gear.

If I had it to do over again, I would have just bought a used AP2 diff rather than the Comptech, though.

Because if you break your 4.57 pinion, they will charge you ~$500 for new gears, $100 for shims, $300 to install the gears into the differential, and you'll still have to pay to have the pumpkin installed on your car.
Where did I quote a post that was posted before my response?

The price of the 4.77/4.76 gears makes me glad I'm running Kia gears. I am pretty sure your gears were stronger than the gears I'm running, but I don't think I give my diff the kind of pounding yours gets. I don't baby the car, but I know from talking with you about it that your situation is quite different and pretty extreme. I light my tires too often, and slide the car around with the back tires spinning too often, but you probably know better than most how that can break things under adverse conditions.

People do need to realize that these cars are tough, but far from indestructable. You can drive 'em hard, but it takes some finesse to stay out of trouble and avoid breaking things. I hate seeing all the "I spun" and "I broke" threads, because it's just sad, but we keep getting new owners, and we need these threads to remind people what can/will happen if they get in over their head, or try to do things in the car that they don't really understand. Just because guys like XViper and Billman can do literally thousands of burnouts without damaging their car does not mean that everyone else can do it. These guys are master mechanics and understand how cars work; They know what they can get away with, and what will get them in trouble. Those with less experience need to realize that getting the experience often comes with a price tag, and that you learn how not to break things, by breaking things. If you play, you pay. There are lots of ways to break or crash an S2000, and over the four years I've been here we've seen way too much of both. I don't want to scare anyone who knows what they are doing into being paranoid about driving their car the way they want because they think it's inherently weak or dangerous, but the car in unforgiving in more ways than just its handling.

You guys be careful. XViper and Billman are master mechanics and can fix anything they break. If I should bust my pumpkin, we've probably got a good used Skyline diff sitting around the shop that I can adapt to the S, and even if I were to end up having to buy an AP2 diff, I've got a shop to swap it out in, and professional mechanics to do any of the work I don't feel like doing myself. Remember that even professional drivers make mistakes and break cars, and that the rule is, if you play, you pay. Don't risk breaking or wrecking anything you can't afford to fix or replace.

It's been done. Check out this thread.
Old topic, is he the only one that managed to install a nissan diff.. ?


I'm getting sick of seeing so much diffs that say boom, i''m seriously doubting about keeping the car due to it's diff problems, i've driven an ITR 2 years before the S and i've beaten the drivetrain on a daily base with no problems whatsoever.

I just want to do launches and not worrying that the rear end might explode... honda should have invest in some more research in the rear end

Honda did a fine job with the S2000 diff and it is plenty strong enough for the grip the OEM tires can deliver. The car was not designed to be a drag car. Did you check out the links that appear in the thread. It's an old topic, but that doesn't make the information invalid. I *think* (but am not certain) that several people have made this conversion and that you can buy a kit from at least one supplier. However, I don't keep up with it (becaue my diff is plenty strong enough for the way I use the car), so I'm not really sure.

It's something I'll look into when and if I reach a point where I need a stronger differential.

Here you go!

I knew you were fast, Red... but defying the space-time continuum!!! That's amazing!

InlinePro has a diff kit they're using on their drift car. If I weren't such a promiscuous car ho, I'd consider upgrading....

As it is, when the next big thing breaks on the Honda... will probably just pay more and trade for an overengineered stock vehicle... M3/RS5/LFA/911, etc.
