    Check out the N/T forum, there is more information on this topic there. Also, try a search, this topic has been discussed before, and I know there are many differences, just I can't remember them off the top of my head.

    Yes use the search, also the NT block does not have knock sensor it does have a hole for one so one can be installed.

    I did search. Guess i did'nt word it correctly. I either find waaaay unrelated stuff or get too specific and don't get anything.

    I did find that the N/T blocks did'nt have the oil squirters. Did'nt find out about the lack of knock sensor.
    I'm looking to buy an already prepped block and found several N/T blocks. Was'nt sure if i could swap the different componants from my Turbo block or if there were other differences.
    Thanks for the help!

    Don't forget some of the other stuff is different as well.

    nt 4g63
    no locating pin on crankshaft
    Pistons are different design
    Motor mount arms (front and rear attached to block) are different
    water pump pipe doesn't have outlet for oil-water cooler
    lower thermostat housing doesn't have the fitting for the oil-water cooler
    no lines for the oil water cooler
    head plugged where oil feed comes from
    no drain hole on oil pan
    different tb
    different cams
    intake manifold lacking one vacuum source on the manifold

    Alot of this stuff is easily replaced, but it depends.

    Of course the stuff mentioned above about the oil squirters not being there and the hole being there for the knock sensor are true.

    Will i need to tap the hole for the knock sensor or is it already tapped? I assume it would be ok to use in a different location?
    Also, on the oil squirters, can i just swap the over or will i have to drill and tap some holes???

    Thanks again for the reply!

    Are you just getting a bare block or a short block? Seems like everyone is giving you info about a short block.

    As a bare block, no oil squirters or even holes for them. You would have to have the mounting locations machined, drilled, and tapped for them. Im not going to say you do or dont need them because there is too much contraversy on that subject and it will turn into more of an opinion war than anything. Do a search on oil squirters and you will see what Im talking about.

    As for the knock sensor, the hole should already be tapped. No real need to be concerned about it. I have heard of a few that werent tapped but I have yet to see one.

    Yeah, i'm talking about just the bare block. I pulled my motor(turbo) and it may be just about as cheap as well as much less down time picking up an already machined and prepped block. I would use my crank and all accessories and put in new eagle rods and weisco or JE pistons.

    Im sure someone will disagree with me but if you are going with a foged piston, I wouldnt worry about the oil squirters. Like I said, search it and you will see all the other threads obout them.

    Thanks for the search tip!
