Dear forum readers,

My 1990 C2 with 126k miles is about time for a complete rebuild.
It has the older version stock engine with the infamous oil leakage.
Just wondering how much does it cost to complete rebuild the engine nowadays.
Many of you may suggested just do the top end ...etc. but I may just bite the bullet and do the complete job.
Has any one of you done a similar or partial rebuild job recently and how much did it cost ?
Any information will be greatly appreciated.

Thanks in advance.

B.W.

You can do an engine swap for $14k from Vertex, no affiliation.

Price can vary considerably. All depends on how handy you are, what you want to do and who you use to do the build.

There are a lot of used parts available thanks to all the singer builds so you can buy used parts (P&C's, cams, heads etc) and recondition them to like new condition for about 50% or less of new. It all depends on the condition of the case and what machining is required. If you choose to fall into the while you are in there grove expect the costs to grow quickly.

IMO this is one of those, plan for the worst and pray for the best. It doesn't hurt to consider some upgrades but don't consider a 3.8 or other build unless you are willing to open your wallet wide. Doing these on the cheap offers little gain for the money spent. Doing right requires a lot of machining costs and new parts.

I am currently doing my own, it is a 993 engine in a 964 so pricing is off the charts for used 993 parts vs 964. Although it is far cheaper to do preventative rebuild vs a rebuild do to a failure.

I did a rebuild on my 3.6L a year and half ago. i ended up doing top and bottom and new clutch. Ended up costing a little over 21k. Some stuff can be saved and reconditioned. Some parts were better off buying new. It's a slippery slope and things can add up VERY FAST. Best of luck.

This is a difficult question to answer due to varying labor rates across the country.

Further, since the lion's share of a rebuild is the parts list, precisely what gets inspected and replaced varies as well.

I would budget $20K for a proper engine rebuild.

I have a 964 with a 993 engine in it done right and that car took a lot of money to make everything flow seamlessly, it is an amazing car and a great daily driver as the 993 engines smooth power delivery and feel makes it easy to drive, coupled with the 964 looks, its a great combination.

This being a 2nd or 3rd car typically means you should be able to take your time and enjoy the experience if you decide to take on the labor yourself. Talk to your local race shop (Porsche or otherwise) to find quality machining facilities or send key components out for machining. I haven't done a rebuild for my 964 yet (only 40k miles), but I have rebuilt a BMW S52 motor for my race car. The process is very satisfying once complete. I got my feet wet by purchasing a broken Gravely zero turn mower and rebuilt the motor and hydro gears. The principles are very similar, but on a much smaller scale.

£14,000 increasingly less valuable British pounds in July this year, top and bottom plus half the rockers and reconditioned cams. Sounds about in line with US pricing. Oh sorry, plus new clutch.

$19 in 2017, but I had a low milage crank and matching intermediate shaft installed that added to the cost. New Mahle 3.6 P&C. Doesn't include RS clutch/flywheel, Rennline engine carrier and mounts, etc.
