99 vs 98 Boxster engine reliability

Just wondering as to which Boxster engine has better reliability: 98 or 99?

I would think that the 2000 2.7 trumps them both but ...

They both should have a dual row ims bearing

By this time, the care and feeding of the engine probably matters lots more than the manufacturing date of the engine. We are talking 14-15 years old at this point.

there were changes - didn't the 5-speed transmission change from 98 to 99?

True, yes ....but I am viewing from a particular angle: low mileage over those years and wham she's whistling around a track.

Had the Bentley book handy, no mention of 5 speed transmission change from '98-'99 for what that is worth. There was a change highlighted in 2000 to go with the larger engine displacement (2.5 - 2.7).

go to the Auto Atlanta online parts catalogue and scroll though the engine section; it shows when all the parts updated. for example, 99 has improved chain tensioners, chain adjusters and ims shaft. improved oil pump, improved hose clamps! etc.

Good thought, yes I didn't think about updated cam drive parts!
