Boxster S (986) Rough Engine Rebuild Cost

Hi Guys,

just looking for a bit of advice really, i'm interested in purchasing a Boxster S off a friend, it's a face lift non runner/starter.

does anybody know roughly how much it costs (on average) to rebuild an engine from a reputable company?

i know it varies on exactly what needs to be replaced but i'm just looking for best and worst case scenario. i've had a look on the net and i can't find much on there. there's 3.2S engines on ebay going between 3-5k.

i'd be very grateful if anybody could help or point me in the right direction

thanks in advance.

Here are a few thoughts on engine replacement options (from a previous post):

Option 1: Used Donor (eBay or equivalent) Engine This is the cheapest route - simply replace the engine you have with another used engine and do a 60K service to get the car back on the road. Future reliability is unknown and you may be right back where you are now (needing an engine replacement) in anywhere from 10K-100K miles. Obviously 10K miles would be a bummer and 100K miles would be awesome - but no one can say for sure which it will be. $3K-$6K.

Option 2: Refreshed Engine Some shops call them "refreshed" or even "certified pre-owned" and others may even call them "rebuilt" even though they are not really rebuilt. This option will generally consist of a used engine that has good compression as-is with maybe new timing chain/guides, a new water pump and/or alternator, new thermostat, and a 60K service. Be sure to check which exact parts are new/replaced because it varies. Again, you may be right back where you are now in anywhere from 10K-100K miles. $4K-$10K with higher priced engines having fewer original miles and/or add'l components replaced and/or coming from better known shops.

Option 3. Rebuilt/Remanufactured Engine A remanufactured engine where the engine is rebuilt to meet the original spec's, mostly using OEM parts. This is a classic rebuilt engine. Some engines may have updates like IMS/RMS but you'll need to specifically check. This option should give you ~100K miles of service but the reliability is (again) completely dependent on the engine builder and the extent and quality of the updates installed to address reliability issues. Likely to have a warranty of some kind so be sure to check the warranty details. $8K-$12K. Higher priced engines have more high quality parts/updates and/or come from better known shops.

Option 4. High End Fully Rebuilt The engine is rebuilt from the ground up with lots of new parts and all upgrades. Buyer may be able to specify some build details as desired. Engine is probably better than anything coming straight out of the factory brand new. Shops that do this work are top-end and their business relies on a good reputation. Should expect ~100K+ miles but check the warranty details. $12K-$22K. This will give you the most peace of mind (and maybe the highest performance) but it comes at a cost. Be aware that you may not get 100% of the engine cost back in resale value but that really depends on the buyer.

In summary, only you can decide which path is right for you.

Seeing that you are in the UK, the American rebuild $$ costs will be different to England.
Try contacting Hartech Automotive in Bolton (www.hartech.org) or Autofarm (www.autofarm.co.uk) who are the UK specialist on the M96 engine rebuilds.

Easiest way to get a clue if it's something really serious is to cut open the oil filter to look for metal shavings.

Add the fact that Porsche no longer offers assembled reman engines, they now only sell short blocks.
