    3.0 Conversion step by step

    Hi all,

    I've got a 3.0 engine and am thinking about swapping it in to one of my cars. It is complete, and I have the new lower crankcase and a new oil pan so that I don't have to disassemble either of my engines to work on this one.

    Anyone that's done this before, what else is needed? If I don't do anything to the internals of the 3.0, will it perform any better than stock? How much better?

    What should I do to it before deciding to put it into one of my cars? Rebuild it? Have the heads ported/polished/etc?

    What other parts are needed for a 3.0 conversion? Will it be even fire after the conversion, or odd fire, or is that something I can choose? If it's something I can choose, why would I choose one over the other?

    As I do this conversion, I will document what I'm doing. That's why I'm asking some very basic questions.

    Are you planning to EFI this engine, is that why you have posted here?

    Yes. I'm not aware of any K-Jet 3.0s. The 3.0L comes with EFI by default.

    I know Josh at DPI sells a trigger wheel that sits where the distributor would normally go, to feed a megasquirt or other EFI controller.

    Is either of your DeLoreans an automatic? If memory serves, the flexplate from the Eagle Premier is exactly the same as the flexplate for an automatic D. I'd put it on the automatic. (I originally wanted to be the first person to have a 3.0L EFI automatic, but I would gladly watch someone else be the first!)
    DeLorean status: 3.0L installed and running

    The project car is currently an automatic, but I might be converting it to manual, if I can get all the parts together, and enough free time to actually do itů..

    If anyone is interested in this, I am currently working on a step by step install of a 3.0. Im putting my engine together right now So I can add to this thread in a month or so. Just the engine related assembly for now.

    Cheap, easy to obtain, and it is a PRV so it bolts right up the the transmission.

    Oh, so it is not a selection of a better engine?
    It is just a locally (US) easy adaptation.

    Well it is a better engine, thanks to 10 years of updates and improvements. MUCH better F/I system, serpentine belt, and the internals can handle more power. Im sure there are more benefits but those are the big ones. The avalability in N/A is good, as the cars were manufactured here (in canada actually )

    For me it was a lazy swap. I needed a new engine and did not want to waste my time with the stock engine and the primitive fuel injection (dont get me wrong it was good in its day). I found the 3.0 for $200 and it bolted right in. If I didnt have the whole rest of the car to redo and could just focus on the engine I would have done something completely different. But I do not have the time/money to do that right now. So the 3.0 is a great middle ground.
