    Default 1JZ Swap Parts Into a MKIII - List -

    I looked at the stickys that are posted above. What I like about them is all the information is awesome, but I want a straight forward * what parts do I need to drop a 1JZ into a MKIII and go down the road * That is what this thread is for. I hope this will help everyone wanting to do the swap. I will make suggestions that helped me, and I assure you they will do the same for you.

    This is if you already have a 5-speed car you're swapping the 1JZ into, if you do not you will need more 5-speed swap parts. I would like to add though if your car is an auto, you will have to cut the tunnel where the shift comes up a little bit, for perfect fitment.

    To start I will begin by breaking down everything into 5 sections Body, Engine,Electrical, Drive train, and miscellaneous parts.

    Safety comes first! So always make sure you check your surroundings!

    Where to buy all of these things?

    I used a number of places to buy the parts? Seriously Ebay is where I got most.

    Ebay
    Driftmotion
    Advance Auto
    Supramania
    Supraforums


    Engine:


    Complete 1JZ out of a JZA70 with a R-154, harness ECU, ect. attached ..............................$2300.00 ---------------Serious I have a very nice reputable company on *EBAY* (100%) Feedback as well.
    Swap mounts for Pre '89 or '89 + .......................................................$120.00
    Oil line so the stock 7M oil pressure sensor will adapt.............................$20.00
    Rubber mounts for the swap mounts, or fluid filled if you have a '89 + .....$50.00
    Stock 1JZ inter cooler and piping..............................................................$150.00
    New Timing belt...................................................................................$35.00
    Serpentine belt, Advance auto, if you run without A/C Part # 745K6............$22.00
    2JZ Water pump....................................................................................$60.00
    I would suggest a new Thermostat..........................................................$21.00
    1JZ Water pump pulley, Hydro Fan pulley will not work..............................$20.00
    If you do not want the hydro pump, you will have to get a 2JZ water pump and
    LS400 Clutch with fan............................................................................$65.00
    Stock 1JZ Down pipe...............................................................................$70.00
    Stock Intake..........................................................................................$50.00
    Oil filter.................................................................................................$5.00
    Suggest engine oil- I used Castrol Edge Full Syn 5w-20.............................$50.00
    Toyota Red Coolant...............................................................................$24.00/gallon
    2JZ Coolant hoses..................................................................................$60.00
    Hose Clamps, I would suggest getting a fair number of these. I had an issue with the water hoses that go to the oil filter housing. I used the stock Toyota clamps and they leaks, so I put some new hose clamps on there. Just as a safe guard...............................................$15.00
    Heater hose, and vacuum lines to make it through the engine bay...............$30.00
    I would suggest New Spark plugs Advance auto Part # NGK 4644, BKR73.....$14.00

    Exhaust work will have to be done with a welder, so if you do not have one, find a place and bring the car there. We paid 100.00 to make everything fit.

    ----------------------------------------------------------------------------------------------
    Here is my suggestion though when a motor comes in. These JDM motors sit for years, maybe 5-10 years. These have a build up of gunk inside, and they have not been ran in years. I like to take the whole 1jz apart, and clean everything with a tooth brush. I then went ahead and got a new Toyota gasket kit for the 1jz and re-gasket the entire motor. I added ARP head studs as well to the mix just to be certain.

    Electrical:

    For the electrical, the harness will need to be modified to fit your car, I will make a post on how to do that. Now the 1jz's alternator is WAY over to the other side. I used 2 gauge wiring and ran it under the core support all the way to the location where it mounts on the body harness. It was not that hard. If you want the stock Boost pressure gauge to work, run vacuum line off the intake manifold to the sensor and it will work. There is really no other wiring besides the main harness which you will have to do.

    Note: when testing the electrical, always make sure all (+) positive wires are not grounded out.

    Your Car's 7M harness or connectors if you don't have it............$150.00
    2 Gauge Wire 6 feet I bought................................................. $13.00 Advance Auto
    Connectors for the wire to the battery, and to the Alt. ..............$4.00 Advance Auto
    Extra wiring to extended the harness.......................................$40.00 Hardware store, or buy spare cut wiring harness


    Grounds: Head to body, Transmission to body, Attach the ground at the fuse box, Ground near the A/C relay.


    If for some reason you motor does not come with this, you will need them.
    Map sensor....................................................................................................$90.00
    Ignitior..........................................................................................................$100.00

    Drive train:

    I would suggest a new clutch.....................................................................$400.00
    Drive shaft...............................................................................................$100.00
    I would suggest a new slave cylinder..........................................................$40.00
    I would suggest a new braided clutch line.......................................................$50.00
    I would suggest new Transmission fluid.......................................................$50.00
    If you want ABS to work you will need to buy a ABS rear speed sensor...........$90.00
    The 1JZ cars in Japan didn't have ABS on all models, or maybe at all.


    Body:

    Braided Power steering line...................................................................$65.00
    Power steering res...............................................................................$35.00
    Power steering hose - low pressure.......................................................$20.00
    2JZ-GTE Throttle Cable.........................................................................$65.00


    Miscellaneous Parts:

    I would have *The Good stuff* For any sealing purposes, oil pan, cam caps around the valve covers, oil pump housing, rear main seal. It works great, and I can say that because I use it on all the motor I do.

    I always have a box of spare bolts, I have 1000's just in case you loose a couple and can't remember where they want.
    A drill always helps make things easier.

    I was wondering if there is a way to rebuild the 1jz water pump or purchase one as I am wanting to keep the hydrofan?

    I didn't end up doing a schematic, i figured Ill just have people send them in, its easier for me that way. I also like having the car here most of the time to test and ensure it was correct.

    Yup, you need a non hydro fan water pump backing plate, and a 2jz water pump.

    Well the hydro water pump from the 1jz is different from the 1jz non hydro and the 2jz doesn't use a hydro pump so yes they're different.

    Ls400- FAN with work with a 2JZ water pump, with a STOCK Ma70 Rad. If you upgrade to a 3" aluminum rad it will not fit, and that is why electric fans were used.
