Our story to this point:
In 2022, I signed up with Second Motors to get of their queue for an EV conversion.
Thus started the hunt for a donor automobile. I discussed final month that the initially chosen automobile for this challenge turned out to be a uncommon(ish) 1988 Porsche 911 Cabrio that I didn’t need to devalue; as an alternative, I restored the little cabrio again to manufacturing facility spec (photographs right here) and determined its a keeper.
What I ended up discovering for this challenge was a 1987 Carrera with practically 300,000 miles on it, and lots complete of things that argued in opposition to any expensive restoration: substitute motor, interval incorrect aspect view mirrors, mistaken seats, 90’s steering wheel, and many others. It had been in an accident to its proper entrance finish 20 years in the past however was repaired + repainted (extra on this beneath). I don’t know if/when the doorways have been changed (post-accident?) however they’re a barely totally different colour. Type of a sizzling mess…
The coupe began out as an fascinating challenge automobile, with a number of uncommon choices. The colour is gorgeous and weird “Lagoon Inexperienced Metallic” which reads as a light-weight blue to me; the paint was principally clear; it has rear-wiper and a sunroof delete. It made sense to revive the M491 Cabrio again to inventory, because it was nonetheless price greater than the acquisition worth plus the prices of restore. On a “Frankencar” like this, that made no monetary sense.
It took a yr for my place within the queue to come back up. In August 2023, I shipped the 1987 911 coupe to Texas for its EV coronary heart transplant. It’s been some time since I final mentioned the place we’re with the challenge, so I assumed I might share some updates as to our progress. It’s been principally excellent news, with a number of surprises thrown in:
The excellent news: The little striped monster arrived in Texas in fine condition, with no points from transport. I had dropped an Apple Airtag within the glovebox to trace it throughout nation (journey time was about 3 days).
Quickly after arrival, the Motor and transmission have been eliminated and not using a hitch (photographs beneath). Then the brand new HVAC system went in, as did a retro period-correct Blaupunkt Bremen SQR 46 DAB head unit (Bluetooth no display screen!). (I’ll ultimately substitute the previous audio system.)
The shock was {that a} identified rust spot — the realm across the 12-volt battery (nestled in opposition to the driving force’s aspect entrance fender) — was a lot worse than thought. It had rusted so badly that it was affecting the structural integrity of the entrance trunk the place the brand new EV batteries go — at practically 200 kilos, they want strong assist. You possibly can see the earlier than and after photographs beneath. $9k later, it’s nearly as good as new.
In late December, the EV motor arrived. After we started this challenge again in Could 2022, the state-of-the-art was the Fellten EV Collection 1 motor. At 350hp, it was a pleasant bump up from the automobile’s authentic inventory 210 hp flat 6.
Alas, the Collection I ended its run, and so we have been delayed in getting the Collection II Fellten package (see picture beneath). That delay was well worth the wait because the Collection II horsepower is 440 — greater than double the unique inventory engine. That could be a helluva a lot of go for a 2500 lb automobile. For comparability, a 2012 Audi R8 has 420 horsepower and weighs ~1000 kilos extra. The 0-60 occasions are related, however I think the little 911 will really feel quicker.
I’ll replace once more as soon as the motor goes in; Images of the progress beneath:
