    Who has installed a B28E in their dmc?

    Hi

    Iím considering doing this swap. How hard is it to make a B28E work? The engine is out of a euro spec Volvo 760.

    From what I can see it has a fuel pump on the cam cover, as opposed to the deloreanís electrical one.

    Would you recommend keeping the Volvo fuel and ignition system?

    My VIN:    Formerly 10372, currently 4728

    VIN 4728 is on standby to have its new exhaust installed, and has lost priority to a kitchen/living room renovation & 60-80 hour work weeks.

    My VIN:    04194: 5-Speed, Black Int, 79 Peugeot 604 Manifold, 05052: 5-Speed, Gray Int, 78 Peugeot 604 manifol

    Externally the B28E Volvo swap should be the same as the B28F Volvo swap that I performed on 4194 a little over a year ago. Changing the necessary parts to convert a Volvo PRV to a Renault / DeLorean PRV took a couple hours and wasn't too difficult. Just make sure to torque the lower crankcase 100 percent by the book and you should be fine. Aside from the lower crankcase, you'll need to swap the crank pulley, passenger side valve cover, the alternator mount and various oil and temp sending units. I can't recall whether the exhaust manifolds are the same. Either way, it would be a good idea to replace the exhaust manifold gaskets and hardware while the engine is out.

    The later Volvo PRV's, 84 on IIRC, use a different water pump and water pump Y-pipe. The later style water pump / y-pipe combo might clear the k-jet manifold, but it will not clear the Peugeot carb manifold, so I swapped the water pump and pipe assembly from my old PRV.

    Make sure that the engine is indeed a B28E as opposed to the later B280E. Swapping to the later, even fire, EFI engine would entail much more work. Also, check the build tag to confirm that the engine is indeed a euro spec engine. The Volvo tag red in color and is a little smaller than one square inch. It is located on the side of the engine near the oil filter / oil pressure sender.

    With regard to the B28E fuel system, I believe the euro spec cars did not have a lambda system and they might have a different calibration to compensate for the higher compression ratio, but I don't know for sure.

    On an aside, how did you find a euro spec engined Volvo on this side of the pond?

    Good luck with the swap!

    Thanks for the extensive answer!

    Iím pretty sure itís a B28E, out of an euro spec 760

    Nice! And it's already out of the car, which makes it that much better. Plus, as a bonus, you got a highly sought after bolt on water pump pulley :-)

    I forgot to mention that the valve covers and flywheel need to be swapped out as well.

    The little red tag on the side of the block should say B28E.

    Even if the fuel system is in an unknown condition, the parts still have core value. I recouped half of what I spent on the Volvo PRV by selling the core K-jet parts.

    I have 4 fuel distributors all together, partly because I have a B27 in my possession as well.

    Whatís the big deal about the bolt on pulley? I think I might have thrown one in the trash tonight. Should I go look for it?

    Click on the link, its not so hard to do. I went with EFI and a stand alone management system, again its mostly plug and play..

    The advantage of the bolt on pulley is that it allows you to use the less expensive Volvo water pump as opposed to the DeLorean water pump with the pressed on pulley. Plus it's a lot easier to install the bolt on pulley than pressing the pulley off the old pump and onto the new one.

    Over the years various vendors have offered bolt on pulley options; however, there have been extended periods where the pulleys have been unavailable.

    To put "less expensive" in perspective, the GMB 190-2040 pump is about $75 new (non-reman).
