Well, something changed. In a earlier correspondence with Alpine in South Africa I received the following message on December 7th:

"Hi We will send a 53mm pulley John"

On December 10th I received this:

"Hi we never had a 53mm pulley in stock we are making one. Please confirm all the parts you require regards John"

On December 17 this:

"Hi Scott, the 5psi pulley is the smallest we can go, to get more boost we would have to manufacture a larger crank pulley that would quite expensive. We will have update to a larger supercharger MP 90 soon keep in touch Regards John"

I assume that is our Aussie pals endeavor....

And the other source I was investigating:

"This pulley was designed by NGM to bring the boost and power level of the Alpine supercharger kit for the 2.7L Tiburon up to Stage II level. With headers and catback and the addition of this pulley, you should see a boost increase of approximately 6lbs. Total boost you should see is around 6lbs.

$165.95 $145.95"

I called him about fitment. His reply on December 7:

"It will fit. Alpine used the same offset pulley that I use on my kits so there should be no problem with the offset."
