I don't think so... As long as the whole part is heated, it should increase the ID of the flywheel as well as the OD...
A quote from jeff: "The manual says the aluminum flywheel has to go on tighter due to the fact it expands at twice the rate of steel when heated. It even suggests heating the flywheel up on a hot plate."
Which follows traditional press-fit, heating and cooling practice... If you're ever board, give it a try and mic the ID before and after. I installed a fidanza in a customer's car over the weekend. Would have been a good opportunity to try it then
His press fit on as normal though, so there was no need to get creative...
Later,
