I picked up my 2023 M/T 718 Spyder from Rick's Shop in Upper Nyack, NY last Thursday. In less than 4 weeks, Rick converted my motor to 4.5L, installed the clutch, lightweight flywheel, headers, OAP, modded the differential and re-geared the transmission. Drama free is the best way to describe the process. Rick's shop is brand new to him, in an old bakery. It's immaculate and also laid back. There were probably a dozen GT4/Spyders visible on property, including a gorgeous Shark Blue GT4RS on a lift. My car was waiting for me, full of race gas, a box with an owners manual and boostane. I was greeted by Rick, his engine builder and a friendly German Shepard. Rick and I jumped in the car for a test drive, and he gave me instructions on the break-in miles ahead. Rick's confidence in this motor is inspiring. My experience with him over the course of the project, through pickup was fantastic. I was able to get an on the fly oil change at Porsche STL (KILLER DEALERSHIP) right at the 1,000 mile mark of the end of the break-in period.
After the first 1,000 miles and the oil change I was able to drive the car up into its power band. The car rips. The naturally aspirated power is right there with you all the way to the redline. I wasn't surprised about the power down low, but what shocked me was a drastic improvement in 4th and 5th gear torque. Drop from 6th to 4th to pass on the freeway and the car is unrecognizable, pulling hard to the 8k redline. I personally feel like it easily performs with the 991.2 GT3 with this setup. I went catless because as expensive as NA power is, why not? Rick retaining the OEM muffler with its reliable valves is essential. With the top down, windows up and valves shut, the car damn near indistinguishable from a stock 718, you can have a conversation. I can say that it feels like a new car. It's the torque. I've seen dynos from bolt-on's and tuning on this platform with impressive HP Gains, and have had a 991.1 GT3 with tuning to 93, catless headers/exhaust which was sightly noticeable. I weighed the cost of the build against the bolt-on/tuning options. It comes down to the torque, there is no comparison in this car and one that's stock. From the factory the car had plenty of HP, just not torque. The 4.5L Build delivers real world, usable torque and it is wonderful. The 718 chassis is a phenom and with this package it really does fit in with the best mid engine sports cars.

Gauging interest in my 2016 Deman Spyder
All:
I am thinking of selling my Deman Spyder. It is a white 2016 that I have wrapped in Inozetek Supergloss Metallic Racing Green. Has approximately 50,500 miles, and about 5,000 since the engine was done. The total price of the work was approximately $70,000. I bought the car after the work was done.
Don't get me wrong. I absolutely love the car. Drives incredibly well, pulls like nothing else I have driven. But, I have three cars and wife is telling me one needs to go. Been married 34 years, and listening to the wife occasionally is how you get there. Living in California I don't want to mess around with smogging the Deman, so it will likely be the one to go. I know there are ways to try and get around it, but I am just not comfortable doing so. All else being equal, would probably keep it over my 16RS, but all else is not equal.
So, just trying to gauge interest, if any, and also trying to get a sense of what people think it might sell for since there is really no market for a car that has had $70,000 of work done to it.
Thanks ahead of time for any thoughts.

Hey Jonathan do you have a link to any pics of your Spyder somewhere?

Yes that would be great. I would love to see how a 3/4 rear shot would sparkle in that green on a sunny day.

I believe only one Deman conversion has been sold on BringATrailer and it didn’t get much of a premium there as they tend to favor unmodified cars.

You should post details beyond just the color, such as transmission type, options, and all of the modifications performed.
