Just as the title states Will a 01 XJR Supercharger fit on an 03 S Type R?

Thanks.

Pick a thread flsupraguy, you now have two identical threads in both sections.

I'll take a stab at this and say since the 4.0L engine on the 01 XJ is totally different than the 4.2L on the S Type R, I don't see how they can be the same. Now, I don't own either, but usually that rule of thumb rings true between parts interchanging.
