    Bring a Trailer (BAT) Thread

    Yes, I have purchased 2 vintage Honda bikes, a Porsche 968 Cab, BMW E36 wagon, E93 M3, BMW 525 wagon that I converted to an M5 Wagon, a 1954 Chev Sedan Delivery and a 1996 Jaguar XJS Convertable. I have sworn off buying anything more for awhile and sold the 968.

    Thanks, see the jugs at the side of the boat? Volvo diesels, oil last changed mid 2021 ..... around 24 litres per engine. The stuff that came out looked almost good for road paving. Going to change again next weekend before adding hours.

    Official 390 E.C. Thread

    I kinda miss the great classic while am happy with her replacement. We bought from Ken in the fall of 2018 and now really pleased to know she will be enjoyed on Lake Erie! We bought a 2006 Doral Alegria which is for sure bigger and absolutely has less storage space. And yes I too am planning...

    Electronic fuel injection conversion

    there are no exposed electrical components added in the system. the explosion proofed alternator and distributor is sealed for marine use.

    Electronic fuel injection conversion

    Yes two separate fuel systems so that both engines are independent of each other. Original ignition might have been OK and perhaps I should have left it alone. The self learning is for fuel mixture and dead easy to set up. Ignition timing is not self learning. The boat simply works better, I...

    Electronic fuel injection conversion

    What can I say. Bigger job than expected & very happy I took it on. I also did a few things twice because I didn't chose the best distributors are the beginning. Along the way I started working with Chris at https://www.efisystempro.com/ He supplied some the parts I have used and even gave me a...

    Electronic fuel injection conversion

    I used K&N spark arrestors because the original units looked so restrictive, pretty sure originals would have fit just fine as the unit basically is a Quadrajet in dimension and mounting. O2 sensors live hanging on the bottom of cars driving in the rain and snow which is more harsh than an...

    Electronic fuel injection conversion

    Hi Chris, I used the O2 sensors and some plates i found on Amazon or eBay that sandwiched in the risers. So that meant longer bolts and fresh gaskets. One of the O2 sensors failed early on and as the install was really fresh I spent a fair bit of time trying to figure out what I did wrong. New...

    Electronic fuel injection conversion

    I have a pair of Q Jets for sale. There is a reason the entire world has gone away from carbs. Fuel economy is part of it for sure but I think a bigger consideration is how much longer engines last now than when carbs were used. Regardless I get it and if you come back to the project I would be...

    Electronic fuel injection conversion

    I did not record consumption before and have only done one longer trip on Lake Ontario from Port Credit to Wilson and back. Default AFR is 13.5:1 at a cruise of 2500 so we used more fuel than I think is necessary. I plan to change my target AFR to 14 or the low 14's as I develop confidence...

    Electronic fuel injection conversion

    Well I did the swap to the Holley spread bore kits on my 454's and happy I did. The quadrajets were leaking and required too much cranking to fill the float bowls. First plan was to rebuild them then carry on but decided to jump in and do the conversion. I set up the engine mounted fuel pumps...
