How much does an engine rebuild add to 997.1 value ? - Page 1 - 911/Carrera GT - PistonHeads UK

A nice, tidy 997.1 with a clean bore score report but original engine seems to be around £25-30k at the moment. I'm interested in opinions as to how much more do we think a "full" Hartech rebuild will add to a car's value? I'm thinking that if a car needs a rebuild, it needs a rebuild and that doesn't really add to the selling price. What are your thoughts please ?

Depends on how recent the rebuild was Id say this appears the best value manual 997.1 I've seen recently. £28k with a freshly rebuilt engine https://www.portiacraft.com/car-detail.php?id=3593 Its odd how many Tips I've seen with recent rebuilds. Always pondered how difficult a gearbox swap is on one, if possible at all

It depends. Hartech also go through the car - bumper to bumper - and report on anything that needs doing / might need doing (as well as providing all the options for the engine). If the previous owner has said yes to the lot (as I did) then you are getting far more than a good engine. Mine, as an example (a 2008 C4s with 63k miles) was upgraded to 4.1 along with a full rebuild, as well as new coolant lines, coolant tank, air con and brake pipes, oil cooler, clutch, tandem pump, oil pump, engine mounts, coil packs, cats, manifolds etc. And it had complete new suspension at CG 5000 miles ago. Bill was well over £20K for Hartech work alone Trigger's broom and a great buy for someone as all the work probably only makes it easier to sell / adds £3-4k on asking price. But not for sale

For those in the know, forumers, Porsche aficionados and the like, it adds value. For every one else it just makes the car easier to sell and potential buyers confidence that they’ve at least ticked all the right boxes before purchase. In my mind it’s the mileage rather than engine rebuilds that prospective buyers look for. Anything over 100k regardless of a Hartech rebuild will be difficult to sell.

I think that’s probably true around the 100k miles point however it’s a bit crazy when you consider that a lot of these cars that have received the hartech overhaul will also have had refreshed suspension etc. Yes there will be age related wear and tear in the cabin but if all of the running parts have been updated, the mileage become less important and more just a number.

As a benchmark - one listed today that has just had a full rebuild for £30K https://www.autotrader.co.uk/car-details/202410074...

But rebuilt by who ?? In other words, a refreshing of the same known issue or a fix and refresh ? (Apologies if I just haven't read the ad properly !) Edited by ChrisW. on Monday 7th October 20:50

Edited by ChrisW. on Monday 7th October 20:50 Doesn't say. 30k for a 997.1 Tip with 106k miles is steep IMO. The ad mentions an engine rebuild with hoses replaced and Aircon re-gassed but nothing about the dampers, bushes etc

I think the reality is perhaps 5k on the value if its a thorough Hartech rebuild, as opposed to just being 'fixed'. Arguably, its worth more than that, perhaps as much as 10k.

If it was a £15k fix, renew and forget Hartech reconditioning I agree with the reality ... it is such a shame that this wouldn't add more to the value which I guess is why Hartech try to combine this with a capacity and power increase. Hartech have a great reputation ... others ??

I bought my manual 997.1 privately 8 years because it was a bore score car that failed at 73k and had a full £14400 engine rebuild at Porsche Chester. Whilst that wasn’t solving the inherent weakness of the engine, my thinking was lightning wouldn’t strike twice with the same car, and 40000 miles on the gamble has so far worked. It’s up for sale right now at sub-20k btw.
