Class of 1987 Bristol Straight Six

[Nekomp]

Thankfully, a replacement engine—a 2 litre 1987 BMW straight six from a 5 series—is now available for purchase in place of the original engine in a Bristol.
Any feedback you have regarding the engine would be much appreciated.
A high-pressure pump and a return line to the tank are likely necessities due to the fuel injection system. The transmission looks to be automatic and is likewise made by BMW. What I want to know is if the ECU (which is also apparent in the pictures) need data from the speedo because I can make out an instrument binnacle. On the other hand, does it trigger the rev counter?

Additionally, I'm assuming it's fuel, but I should probably check with the seller to be sure.
I take it the ECU is where you can adjust the settings, right? Lightweight and aerodynamic, the original automobile didn't require a lot of power. Also, it has drum brakes!
I would be very grateful for any feedback you could provide.

One of two Bosch injection systems—the Motronic (129 bhp) or the LE-Jetronic Fuel Injection (125 bhp)—could be powering that M20.

If you need help tuning, go at BWChipTune; it involves changing the chip.

It would be perfect for the power figures, thank you. Up front, the BMW/Bristol had 85 horsepower. Surely the M20 was an effective engine back then? To demonstrate their smoothness, I remember seeing ads with a house of cards erected on the camera cover.

If cared for properly, these will last forever; however, the later Motronic injection is the better choice due to its superior technology and dependability.
Make sure the cooling system is in good working order; otherwise, the alloy head will be goosed, thus it's best to stick to the service schedule from the E30 and E34.
