  • Project Litl'phant: Building a Toyota 5V-EU (4.0 liter Hemi V8)

    You may... or may not have seen one before.... these are the first 2 pics I saw of one....




    and more recently I found this pic from a hot rod




    A few details: The "V" engine line began in the early 1960s to power larger models. In 1967 The Toyota Century was introduced, and it was powered by the 3V, a 3 liter hemi V8. The engine only powered the Century until 1996, when the 12 cyl GZ came out. There is no relation between the 5V engine line and the 1UZ engine, the only similarity is they are both 4 liter.


    Here are some specs found online

    Engine manufacturer Toyota
    Engine code 5V-EU
    Cylinders V 8 in 90° vee
    Capacity 4 litre 3994 cc (243.729 cu in)
    Bore × Stroke 87 × 84 mm 3.43 × 3.31 in
    Bore/stroke ratio 1.04
    Valve gear overhead valve (OHV)
    2 valves per cylinder
    16 valves in total
    maximum power output (JIS net) 164 PS (162 bhp) (121 kW)at 4400 rpm
    Specific output (JIS net) 40.6 bhp/litre or 0.66 bhp/cu in
    maximum torque (JIS net) 289 Nm (213 ft·lb) (29.5 kgm) at 3600 rpm
    Specific torque (JIS net) 72.36 Nm/litre, or 0.87 ft·lb/cu3
    Engine construction light alloy head & block
    sump wet sumped
    compression ratio 8.6:1
    Fuel system EFi
    bmep (brake mean effective pressure) 909.3 kPa (131.9 psi) (with a BMEP of 131 there's some (a great deal) serious room for improvement)
    crankshaft bearings 5
    Engine coolant Water


    The engines REPORTED mass is what first attracted me to it.... in 2 places is was reported to be 130 kilos (286#s) - MORE on this in future posts



    Well... back in March, I found one available on YJ....




    So I bought it...... I bought this particular engine because it came with the distributor - two different engines were listed but I wanted this one because the other didn't have the distributor

    While waiting for it... I also bought(found) a FSM, and the correct starter for it




    and I also needed a phone upgrade - so a new Samsung S9, with "bixby" photo, and you can translate....






    more to come.....

    Very nice purchase. What do you plan to put it in?

      Well... that will depend on **IF** I can get it rebuilt - Toyota no longer services this engine at all - there are no parts currently available for it I'll TRY and get custom gaskets made - waiting to hear more on that...


      The engine arrived... and the shipper broke the distributor...





      Getting it from the pallet, to the engine stand







      beginning to dismantle.... blood not 10 min in...




      further dismantling....





      more to come....

        Toyota no longer services this engine... nothing that is 5V-EU specific like gaskets, bearings, rings, pistons, rods, crank, etc., etc...... So care must be taken during disassembly, that nothing gets damaged if at all possible....

        The gaskets didn't fully cooperate during removal





        They are now @ Cometic Gasket - I'm waiting to hear back on **IF** they can remake my gaskets.....

            I hope to be able to actually get it rebuilt, and in that vain, the first bit of good news...


            Cometic can make the crucial gaskets!!




            So a bit more about the 5V-EU... I primarily was interested because I had seen specifications that listed its mass @ 130 kilos(286#s) - If true that would have been spectacular, but alas, the 130 kilos was false hope.



            There is the engine stand mount on the back of the engine, and the weigh was done without exhaust manifolds - but it was weighed with the intake, and the flexplate in place - engine weight - 370#s(168 kilos) - still light, but not 130 kilo/286#s light.






            The engine is EFI, and attempting to modify it to accept a carb just won't work, fuel is bound to not be picked up - see the entrance to each cylinders runners are evelvated - a carb will not properly feed this engine using this manifold as a base....





            But..... there is room to modify the manifolds throttle body opening....




            A 302 Ford throttle body (should be enough for 300hp) could be fitted, its id is 3". The current throttle body stage isn't likely large enough, it might be able to be overbored to 3", or the red dotted lines show the area that could be removed, and a large throttle body mount added.



            more to come....

              bigger or more intake would be a lot better.
              Nice build

                thank you..... as to the manifold modification, that is a little bit down the road after I get the ignition and EFI systems(management plans) sorted.

                The gaskets have arrived, I'll be laying them up on the block and intake manifold in the next day or 2 to make sure it all lines up. Still don't have timing cover, or water pump gaskets - I'll be concerned about that later if I need too.

                In the mean time I've been thinking about the ignition system since the shipping company busted the distributor, which may be(is likely) a blessing in disguise.

                So my plan for the ignition is a crank sensor, and cam sensor.

                For the crank sensor, I'll take an existing crank sensor and mount it to the crank pulley, making sure to get it re-balanced.

                For the cam sensor.....



                The plan is to use the existing pick up @ the very base of the distributor - remove all but one of the spokes, and then use that spoke as the cam sensor. The remaining cast housing will be machined away at the base/mounting flange, and a small cap placed over the pick up and single spoke to keep dirt, and debris out of the way.

                This should allow me to run the ignition, and if I want sequential injection. As of now, I'm thinking of running GM type wasted spark coils so I can retain the hemi look with individual wires going to each plug.

                  Now this is a development.....

                  About the time the engine arrived, I was still working on a transmission solution. The easy answer appeared again on Yahoo Japan... https://page.auctions.yahoo.co.jp/jp/auction/m54403331



                  It is an A340E for an early 90s Century, it comes with the bell housing, unique to Century, and torque converter, also unique to Century. So I bought it.


                  While it does provide me a transmission solution, at the time I wasn't aware of THIS:




                  I've spoken with the adapter's manufacturer, and he believes the 5V-EU bell housing can also be adapted!!! Since the bellhousing doesn't get modified, I'm left now with a "2 in 1" option. I can use the manual trans set up while I'm still able, and if need be, I can swap the auto back in at a future point in time IF I can no longer drive a shift, or I'd want to for some other reason...???


                  DEFINITELY more to come.......

                    I dont think that balancing will be neccecary,as its weight is zero...

                      And,this will not be a budget build i think.Many $$$ parts needed..
