    Default Oil/Coolant Feed/Return line For Ka24det

    Im in the process of putting something together for my KA-T I was gonna make a post but I'll share what I have so far.

    OIL FEED LINE FOR KA24DET

    Starting at the block where the stock oil pressure sending unit is located and making the way to the turbo:

    1.) http://www.nissport.com/catalog/prod...EquipmentType=


    This goes in place of the oil pressure sending unit into the block. The stock sender fits in the 1/8 BSPTfemale end of this piece (not seen because it is sitting on that end), and there are three 1/8" NPT female ports used to connect your feed line and other items, such as an oil pressure gauge sending unit or oil temp sending unit. $49.00

    2.) http://www.amstreetrod.com/961603ASR.php4

    Oil line to NISSPORT oil sending unit adapter (1) $1.68
    part no: 981603 -3AN to 1/8 adapter

    3.) http://www.anplumbing.com/shop/shop1...d_num=63010160

    Oil feed line (3 ft) $15.59
    part no: 63010136 -3AN Female Swivel Both Ends - Size 3 Hose

    4.) http://www.takamotorsports.com

    Oil line to turbo adapter 7/16-24 I.F. to -3AN:

    .060" oil restrictor (Journal bearing). This is to ensure the proper amount of oil is getting to your T25. Unrestricted oil flow will blow through the turbo oil seals and coat the insides of your intercooler pipes. It has 1/8" NPT threads will fit into the nissport adapter. $11.00

    .030" oil restrictor (Ball bearing). This is to ensure the proper amount of oil is getting to your T25. Unrestricted oil flow will blow through the turbo oil seals and coat the insides of your intercooler pipes. It has 1/8" NPT threads will fit into the nissport adapter. $12.00

    OIL RETURN LINE FOR KA24DET
    I used the stock return pipe from a U12/U13 Bluebird or W10/11 Avenir SR20DET for those of you that aren't familiar these are the AWD varients of the SR20DET commonly swapped into the FWD B13/B14/P10/P11 chassis. I slightly modified the bend of the retun pipe and braze welded it onto the oil pan and I cut the flange part off leaving about 1/2" of pipe to attach the rubber return line hose which is 5/8" which I got from autozone part number 4492. Also you like need a staright piece of 5/8" O.D. pipe to join the modified rubber return hose together and for clocking purposes.






    Since I can't find an original picture of teh return pipe I used here is a screen shot and part number 15197-79E01:

    COOLANT RETURN/FEED LINE FOR KA24DET:
    These two trick banjo fittings bolt directly onto your T25/T28 CHRA (14mm Banjo to 1/4 NPT):

    1.) http://www.atpturbo.com/Merchant2/me...gory_Code=GTBB
    $22.00 x 2


    2.) http://www.wicksaircraft.com/catalog...252/index.html
    For the easiest connection to the water return and outlet pipe you will simply need to bypass your coolant lines to your throttle body and also use these fitting to tap into your banjo supplied 1/4" NPT tap with these 1/4" NPT to 5/16" straight hose fitting (HARD TO FIND!!!)
    $1.45 x 2


    3.) Here is a picture of the coolant outlets that you will need to attach a lenght of 5/16" I.D. to and run them over to your turbo.
    INLET AND OUTLET DOESN'T MATTER HERE AS THIS IS RUNNING THREW THE TURBO CHRA:
    NOTE: IM USING A S14 INATKE MANIFOLD SO MY UPPER WATER LINE IS IN A DOWNWARD FACING POSISTION AS TO A S13 INTAKE MANIFOLD WOULD SHOOT OFF TO THE PASSANGER SIDE IIRC.

    Lastly you need some 5/16" I.D. coolant hose to connect the feed and return to the turbo.
    This shows what has have been bypassed:


    Littlle modification update on the throttle body for ease of routing coolant lines:



    and here are more pics showing the routing of coolant lines:






    More pics will come later still waiting on parts to come in the mail.
