Market for big bore 996 cars from FSI, Slakker, etc - value premium over stock

I'm curious what folks have seen regarding the price for well sorted 996's after a rebuild from a reputable shop. It seems these almost never make it to the market so it's pretty hard to understand how much of your money you might get back after a major job like this. It looks like FSI is starting at about $40k. Slakker is around $30k. How much have you all seen the value of the car increase after its installed? Crazy to think you could get back half of that when you sell - e.g., if I spend $30k on an engine build for my $35k 996 4S, think it's crazy to imagine my car could be worth $50k? Thanks in advance

Personally at 50k I'd be looking to spend the extra and get a turbo. For a fully rebuilt LN motor I'd probably be willing to spend an extra 8-10k or so on top of an example with a stock motor for peace of mind. But I wouldn't specifically search one out and instead just find one running well with the stock motor. But I'm a cheapskate so what do I know.

Great question. I know that when I purchased my car, I spent $7G on a 45000 mile car to do waterpump/aos/rms/clutch/flywheel and the solution. I think I would have spent the additional $5 to $7K if there was proof of the work. Similarly, IF I REALLY WANTED A 996, then I could see spending the premium cost for a confirmed, well sorted, big "block" 996. For the average buyer, it would likely be ignored and the car would take a long time to sell.

I�d only pay a premium for a rebuilt engine if it was confirmed by signed document that Jake Raby himself farted in the car at least once.

Ita been proven over the years in bat auctions and private sales that a JR or other well rebuilt motors add aboit 10-15% more value to the car. JR does not support the motor past the 1st owner and if the value was to approach $60k people would just buy a turbo.

I don't worry about resell value, I'm never selling mine. But I do know that if I sold mine, I'd lose money. I have spent a lot of money on mods. (FSI 4.0 with all the extra performance upgrades, coil overs, GT3 Cup adjustable control arms, side skirts, GT3RS wing, carbon fiber mirrors/door handles/panels, wheels, roll bar, exhaust, and probably several other things I can't think of) I could have a turbo for less than I have spent, but I'm very happy with what I've built. I still have a few things on my list of potential to-dos, but not many.

Ha, my signature photo reminded me of more....MOMO steering wheel, FF shift ****, 997 GT3 Shift console...the list never ends. Buy/build what you want. Just be ready to keep it!

Someday, long into the future, market prices may reflect the money spent today on a high quality rebuild by one of the experts you mentioned. But you don't buy any porsche, and spend a ton of money on it with mega upgrades and enhancements and expect to flip it to break even or turn a profit. Just not the way it works. Heck, I have owned my 996 for 22+years and have willingly spent way more than my original purchase price on the car with maintenence and upgrades. For sure, i plan on spending big bucks in the next few years on a kick *** proactive rebuild as well. But I am not looking to flip my 996, nor attempt to make any money on it. Instead, I am looking forward to enjoying the car for another 22+ years on the street and track. All part of the fun of 996 long term ownership.

FTFY

For sure if you spend $40k for a FSI rebuild or $30k for a Slakker rebuild you will be getting close to Turbo $$$ , but if you start with a Turbo and upgrade the Power, Suspension, Exhaust, Wheels, Tires, Interior, ect you can spend WAY more .. I'll bet that if Tex or CG996 had started with a Turbo their 996 total expenditure would be very considerably higher...Us car enthusiasts love to upgrade and personalize our cars....and don't plan on selling them or try to recoupe the $$ spent enjoying them...that $$ is allocated for the enjoyment of the car.. I have built several big bore m96 engines with Nikasil and all the goodies and have driven FSI big bore engines, no doubt the power is impressive ,but my 1999 still has the 3.4 engine with 193K miles and runs plenty strong enough for me at my age at 300HP ..The Engine/Power to me is only 1/4th of the car...The Looks, Handling/Ride Experiance, Comphort are 3/4ths of the car to me....Sure if I were 30 years younger the POWER would be a bigger priority , but I have been there and done that.... Yes the extra Power/Reliability is worth some $$$....to me like Dejeeper said maybe $10k-$12k more just to have because .....

What he says. 996 is perfect as a �performance art� palette.

If I were in the market today, given the age and questionable history of every engine, I would pay a premium for a well documented, maintained, FSI or Slacker engine. Certainly not the cost of the engine but it would be preferable to a maintained stock engine because I know it will last longer. Maybe $7k-$10k more? Quite subjective. There are 2 exceptions, a collector (which I'm not interested in) or a roller, where I would be able to define the engine that goes in, Like and R44! Now, I have an FSI engine that I paid $25k for, specifically for this reason. I maintain it and it will run like mad until I'm dead. Whatever my son sells it for is of no consequence to me.

They make it to market all the time? You can see the perceived value on BaT. it's 0-25% of the rebuild cost, which is a very fair price.

I have an early 1999 amber coupe factory Aero car with a Jack Raby Stage 2 3.8 and yes Jake farted on this one personally 😀- it is not for sale as it is one of the best looking and driving Porsches I have ever owned after 40 years of owning almost all the models. Rich

I am contemplating selling my 2002 Boxster S with a FSI 3.6 stage 2 engine . Engine has 10k miles the chassis has 145k . I wouldn't take less than 25k for the car . Is it worth it ? I think so but others may not . She is drop dead reliable and pulls like a horse . I have to make a decision on if I really want to sell or not .

Unfortunately a FSI Boxster selling for $25k is the same ballpark of a 911 with engine upgrades the market choice is obvious unfortunately for you but if you decide to sell BAT or PCmarket is your best choice GLWS

Yeah " worth " as we all know can very. This car is quite unique not only for the engine but the Aero enhancements. OEM GT3 front bumper , GT3 side skirts and Joe Toth mini duck spoiler . Tasteful updates in my mind others may hate it . Like anything else just need the right buyer . Appreciate the feedback . Thanks

I think it would be worth $25k! If I can swing it if/when it becomes available, I�d jump at the chance to buy it.

What I know now, I�d pay the 10-15% mark up for either of those rebuilds. That said� I couldn�t see spending $30-40k on a motor and still be in a 996. I put the $40k+ into a newer 911 platform.😎

Agree, the power is relative to age (for us geezers) I spoze. I had a killer heavily moded 930 (back in the age of dinosaurs) and it was a blast. Yes, anything on a turbo cost more than any NA Porsche. The newer 3.6 996 is better, maybe a tad slower @ 0-60, but overall just fine. While something newer or with a JR/FS1 engine can be "better", maybe yes, maybe no. While I am currently having a front suspension problem, I still like the C4S every time I look at it. Value on these cars is a subjective range of what drives a person to buy a 20 year-old car. My initial $ spent was on the low side, so I expected to have some "issues". Unfortunate, I underestimated degree of difficulty and cost for my current "issue". Would I sell it? Nah, just fix it and keep it. Sure, spend $$ on this or that, we all have probably wasted a heck of a lot of $$$ over time. At some point, the money value or cost doesn't matter. JMO. YMMV

The last FSI Stage 2 996.1 I saw was a 99 build listed at 50k, which I think is about what you can expect. The original car IIRC had higher miles and I don't recall what was on the engine at the time. I don't think there will be any value increase in the short term. If SHTF and I had to sell it, I know I'm eating at least 20k (mine is low miles, 58k right now) and can't sell for what I paid, but it'll be the last car to go if that is the case. IMO the improvement in the way it drives is worth the expense, as were the R&T coilovers I put on and various other changes I've made. The long term is harder to predict. There are a lot of 996s flooding the market with salvage titles and engine problems (or missing engines entirely), a lot of them are bumping above 100k miles. These cars were neglected and not maintained properly in years past, some are being LS swapped or sold as rollers, because people can't justify the cost of fixing them relatively to their value. I think in the long term if these are weeded out of the market, more value may be given if it is built by a reputable builder with corresponding higher reliability and addressing failure modes. Maybe not - resale value was bottom of the list when I chose to swap mine with a FSI, but the market on these cars is kindof unpredictable. There also seems to be a general cooling off of the 911 market. I've seen a LOT of RNM the past two weeks, some were kindof off base with what they thought the car was worth (like the 996 Targa), but others seemed to be on the mark or close and still missed it.
