Well now this is an interesting find, special thanks to Peter R for the tip! The TVR Vixen is a wonderful but rare sports car. That being said, they had one major issue, the Triumph inline 6 engine and the 106 horsepower it produces. Horsepower isn’t everything, being lightweight can make up for being underpowered, but sadly this engine isn’t terribly light. The owner of this one came up with an interesting way of solving the issue though, the swapped it out for an Alfa Romeo 2 liter with a 5 speed. It’s more powerful and lighter! You can find this Vixen here on eBay in Palos Verdes Peninsula, California with a current bid of $4,550.
Here is that Alfa engine! These twin cam Italian engines can really scream. The seller claims the car is about 200 pounds lighter now and has about 30 more horsepower! You can actually squeeze a lot of power out one of these 2 liters, so I don’t doubt the claim one bit. They don’t say what car the engine came out of, but I would guess it’s from a later Spider. I also imagine it makes this one lively little Vixen!
Having the Alfa 5 speed is a great bonus, but I’m a little concerned about the positioning of the shifter. It looks rather far forward to me. And what is going on with the hand brake? It might actually work great as is, but just need some finishing work to look right. The rest of the interior needs some work, so I would want to clean everything up and make a new plate for the top of the transmission tunnel while I’m at it. With a little work, I think this could be a decent interior for a nice weather driver.
I really love the oddball styling of these cars and the Alfa engine likely makes it a very fun car to drive! These engines have a great exhaust note and produce lots of torque. I’m curious to see what all went into making the engine fit. Given how few of these were built, it’s a bit sad to see it modified. Personally, I like the idea of having a twin cam in it, but I think I might have gone with a Ford Kent engine as that’s what TVR fit in the earlier Vixens. So what do you think of this swap? Do you think it’s really more reliable than the Triumph engine like the seller states?
