    Default Northstar info

    Hi All,

    Just wondering, what sort of crank / cam signals do the RWD Northstar engines have (pre 2007 E67 versions)? I know the earlier ones had twin crank sensors, but I would be certain this has changed on the E67 based ones.
    Retrofitting those earlier ones that have the stupid Siemens PCM would be an interesting project, especially when the Shelby 4.0L Northstar uses an LS1 PCM (See this Ebay Motors Item number: 230237506492)
    Also, anyone know how well a 4L60E might bolt up to one?

    Thanks,
    Ross

    I have the same thoughts on these engines. Interesting...

    There has been a little talk of running early model Northstar's on a 0411 pcm of late.

    But a E67 sounds like fun to.

    You don't happen to have a 0411 pcm tune file for a Northstar do you Ross?

    I think you might find the 4L60E will bolt up well, I would be very surprised if it was a no go.

    The N* IIRC has the V6/FWD trans bolt pattern. So you would need a S10 or other narrow trans housing.

    But the nice thing is after 95 or so, all the 4L60E's had removable bells....

    I know I personally have thought of a 0411 swap in them, but they have so much headgasket issues, and so darn pricey to fix, i would rather toss in an 0411 PCM and a LS4......

    The issue really is running the engine is easy, but running the FDC (Fuel Data Center) and other high tech electronics is unknown territory.....

    Now I wonder if I could retrofit an 0411 to a Buick Grand National.....been wanting to do that for awhile.

    I would think that wouldn't be too hard, the catch, the crank/cam sensor res.

    Yes, but it's quite different to the LS1, looks like custom Shelby. Interestingly though they must have run a 2bar OS on those maybe? And for the life of me I have never been able to find out what crank pattern they had!

    I just recall on Wiki there is something that says the RWD versions of the N* (I like that!) was modified greatly for RWD. From that I assume they were modified to bolt right up to a RWD trans.

    Is that something that can be modifed in the code? As in something that we don't have access to but could be made available??

    You could fab up a crank pulley with the correct reluctor wheel and run the CKP sensor from there.

    I don't know what the N* cam reluctor/tone wheel looks like, I bet it's different...
    could possibly add the correct tone wheel to one of the cam sprockets.

    The winning bid on that engine was $1150....LOL

    I think the crank and cam are not that hard on the early models.

    I have sooooooo much info on the Northstar.

    I have an LS1 PCM running my Northstar currently!
