Boxster 2.9 as Bulletproof as 3.4?

[stevevp]

Hi,
Looking to buy a 2009 Boxster 3.4S around the £28k mark but there are some newer, lower mileage 2.9s around with remaining Porsche warranty. I am not familiar with the 2.9 engine and just wonder if it's as robust as I believe the 3.4 to be?
Thanks in advance for any comments.

Mine's been fine so far - 13000 miles, 2 years old. No IMS to worry about, and a completely different lubrication system.

Is there a production date after which the IMS issue was sorted?

If this is a worry to you, make sure you get the DFI engine.

You mean the new 2.9 engine without the structural issues of the earlier engines or the potentially troublesome Dfi of the 3.4?

About as bullet proof as you can get short of an 993 mill.

I know the theories on that, but I am not aware of any reported cases. Are you?

Buy a 3.4, you wont regret it.

I think it will have to be a 3.4S. If I don't find one soon I may postpone until Spring. Thanks for all the advice.

i've asked this a few times but never gotten an answer, dad's boxster is a 3.4S (not dfi) are the usual problem still associated with this engine?
ie

d chunk failure

ims failure

cylinders going oval

I have covered 75,000 in my 2.9 so far....only been in for the usual 20k services.

When will you break 100k ? Would be nice to see your parts and labour report outside of the usual services.
