I have a 2000 Civic Si and I was wondering if an Integra Type R LSD would fit my car. Also would it really make a difference in the 1/4 mile or is it more useful for autox? I see that Quaiffe (however you spell it) makes an aftermarket LSD but its really expensive. How would an after marker LSD be more beneficial than a Type R LSD?

A limited slip differential powers both drive wheels under nearly all conditions, instead of just one. With an ordinary open differential, standard on most cars, a lot of precious power is wasted during wheelspin under acceleration. This happens because the open differential shifts power to the wheel with less grip (along the path of least resistance). The limited slip differential, however, does just the opposite. It senses which wheel has the better grip, and biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel. In drag-race style, straight-line acceleration runs, this results in a close to ideal 50/50 power split to both drive wheels, resulting in essentially twice the grip of an ordinary differential. In cornering, while accelerating out of a turn, the limited slip differential biases power to the outside wheel, reducing inside-wheel spin. This allows the driver to begin accelerating earlier, exiting the corner at a higher speed. The limited slip differential also controls loss of traction when the front wheels are on slippery surfaces such as ice and snow or mud, providing the appropriate biased traction needed to overcome these adverse conditions. The limited slip differential provides constant and infinitely variable drive. Installation requires complete removal of your transmission so its a good idea to take care of your clutch and flywheel while doing this mod.

 

To answer you question, no aN ITR diff will not fit in a 00 Si trabsmission. And if the car is stock, an L.S.D. more than likely won't show much performance gain in strait line acceleration. It will improve cornering in a great way though. Not so much on deceleration, but on acceleration you will be pleased.

By the way, my experience and opinions are based on the Quaife unit.

 

Thanx for the info. I guess if I want one I will have to get an aftermarket one.

 

Apparently the phanton grip units are not a bad budget alternative if they make one for your car.

 

damn i thought you were talking about the drug

 

haha yea me too.

 

I heard bad things about the phantom grip LSD.

 

I have seen actual quantitative tests and it works.
