    5VZ-FE swap
    5VZ-FE Custom Intermediate and Upper intake manifold
    TL;DR: Does such thing exist?

    The long story here is that I'm actually swapping (trying to) a 5VZ-FE out of a 2003 Tacoma into a 1986 Nissan 200SX and I bought the engine without actually checking the dimensions on it and now that I'm eyeballing this puppy, it's a pretty frigging tall engine and I'm think the whole intake manifold on the top is gonna go past the hood of the car (I also want to slap an old Saab turbo on it)

    The long piping on the intake seems excessive and unnecessary and from my understanding (provided I don't understand a lot about engines, I'm just getting into this whole mess of DIY car building) the long piping introduces a longer turbo lag, since the turbo would need to fill up more space with compressed air, and less turbo pressure overall, since more space needs to be filled up with air as well.
    And don't even get me started on that bend that the air has to go through.
    Please correct me if I'm wrong, this is more of a question than a statement.

    So did I screw myself here? Can I weld something up myself?
    :help:

    Break out the tape measure figure the room you have to work with.

    You have some things to over come the Manifolds Intake and Exhaust are the tip of the ice burg !!!

    As far as I know there are no custom intake manifolds at this time. I guess you searched and did not find any such parts??

    The welding and the building of the intake is the easy part the hard part is all the design and many prototypes getting the flow perfect

    Do you have access to a flow chamber to do all this testing yourself??

    How are you changing the front suspension to handle the weight increase ??

    Building a Custom Exhaust Manifold and running the exhaust

    It is fun enough to swap a 3.4 into a Toyota vehicle merging the engine harness and ECM into a Nissan.

    Getting Power to the ground what are those plans

    Planning a stand alone Fuel management system ?

    Cooling just what are your plans do you have any idea just where the front of the engine will sit in relation to the radiator support??

    Planning a Intercooler ??

    Yeah I'll have to do that

    I do not, that's going to be a challenge

    The car used to have a 302 V8 Ford small block so I'm actually reducing the weight overall, it can support it
    Custom engine mounts are going to have to be made

    Building a Custom Exhaust Manifold and running the exhaust

    Yeah that's a whole thing as well, I'm ready for a challenge

    I have a R150F 5 speed, I'm taking the transfer case off
    And I have a welded diff + some driveshaft that hopefully fits with the trans, otherwise gonna have to work something out with the driveshaft

    Planning a stand alone Fuel management system ?

    Gonna use an aftermarket ECU for all the engine control
    So far my options with that are
    1. Anothe forum thread here by OVTune who claim to be able to reflash the 2002-2004 stock Toyota ECU's, since TRD made a supercharger for it, it has boost control (this is what I'm hoping to do)
    2. Running two Speeduino boards
    3. A company in South Africa called Spitronics makes a decent ECU that will cover most of the things I need (500$ with shipping)
    4. Another company called GoTech makes a better ECU for 500$ but they're a bit older and hard to find
    Cooling just what are your plans do you have any idea just where the front of the engine will sit in relation to the radiator support??
    There's lots of space in the front bay lengthwise, I have the Toyota radiator

    Planning a Intercooler ??

    Yes


    Edit1:
    Option 5 for engine control i guess would be a piggyback, I don't have the toyota ECU, I've seen them online for 200ish, with a piggyback cost on top of it, plus a separate boost controller would end up in the 600-700 range, in which case I might as well go for something AEM or Haltech, my goal is to run full sequential, but if I have to do wasted spark, then it is what it is
