    Default non turbo to turbo swap! need lots of help.

    When you have a non-turbo car and you swap it to a turbo car. do you have to swap the differential too. I put the turbo motor in , the turbo tranny, the drive shaft and I see that the driveshaft (turbo) bolts don't line up with the holes for the differential. Does that mean that I have to swap the whole thing or just the part that you bolt to the driveshaft??????? Please help!!!!!

    I still have the original driveshaft but I don't believe they are not interchangable.

    It sounds like your non-Turbo car originally came with an R180 Diff, and the car that your Turbo stuff came from had an R200 diff. If I had a choice, I stick with the Diff that was in the car that the Turbo stuff came from.

    JMO,

    JMO,
    I bought a parts car for the turbo stuff but the place I bought the car from, is were I was storing the car and they junked the car before I could get the rest of the parts out of it.

    If the trans from the Turbo car was a Borg Warner T5, and the trans from the non-Turbo car was a Nissan mfg'd trans, I believe that the d/s would be different and not compatible.

    It may be possible to use your old drive shaft with the turbo driveshaft gearbox end bit thingy. or i guess the diff end. with the normal drive shaft flange.

    If you pull the uni joints apart and swap the parts over.

    Just a thought, dont even know if its possible..

    Some advice from someone more technical on the subject might help, so people jump on in...

    Default Turbo driveshaft

    The turbo driveshaft is NOT interchandeable with the NA driveshaft. If you are using the Nissan transmission then you must use the NA driveshaft. If you are using the B/W trans then you must use the turbo driveshaft. You can swap the differential flange for the flange that was in the turbo car.

    Read her post, she's NOT unsing the Nissan trans. If the flange from the turbo driveshaft will fit on the NA driveshaft that will solve the problem. If not, then it's off to the driveshaft shop to have a driveshaft built using the turbo yoke and the NA flange. I had to to this when I put a 200SX five speed and a 1600 Roadster differential in my 64 320 Pickup.

    take the u joint off of the end of the driveshaft, and when you replace it, place the original mounting plate (the part that attaches to the diff) from the original driveshaft on the new driveshaft

    new driveshaft-->u joint-->original mounting plate (that attaches to u joint)

    That'd work, right guys?

    That is what we all seem to be suggesting, not knowing if it would work or not having actually ever done it myself. Maybe someone could say for sure that they know this would work from personal experience? Otherwise, like me, you're just speculating.

    What about fuel systems? I doubt the existing fuel system can keep up with a turbo? What kind of car is it?

    On the ZX, just swap the turbo sending unit for the non turbo sending unit-all of the fuel and vent lines are in the sending unit.
