    KA24E Donor Mileage Too High?

    Let's put it this way have more that you think you need before you start. The 240sx transmission is way longer that the 620 71B is... S13 5 speed. This photo was marked 33.25" to shifter which somewhat agrees with what I remember of the total length being around 35". The 71B is 31.5". Here the S13 at top and a shorter D21 5 speed below. The D21's 71C is around 30" Never heard of anyone fitting this 71C into the space of a 71B before. Maybe find a longer driveshaft spline??? The Z series 5 speed from a 720 or second gen S110 (200SX) would be the closest to perfect. Just not as strong.

    L20b manifold options

    You have the L series engines? Well here, the L20B exhausts were terrible with all four cylinders dumped into one outlet down pipe. Worse, the earlier ones with the U67 heads were bolted to the intake above it. The later W58 heads were separate. The U67 heads had square exhaust ports the W58 are round. Our earlier L16/18s did come with a 'cast iron header' 4 into 2 design that separates the cylinder firing order with 1 and 4 and 2and 3 paired. It needs a two joined to one down pipe back to the silencer. The earlier cast headers will bolt to the later L20B heads though even the round port heads. L20B exhaust bolted to intake 4 into one... Mklotz70 (a member here) did make the two pipe flange. https://ratsun.net/topic/73044-rat-rod-header-flange/

    Datsun 521 D21/720 4x4

    The D21 is also IFS but newer, better brakes, engine and co joined trans and transfer case. It is wider, so if plopping a 521 onto it make sure the wheelbase is the same, and the tires may stick pout to the sides a bit.

    521 front end conversion

    Cut the frame behind the rear torsion bar mounts and graft it onto the 521 frame. None of the disc brake stuff will fit a king pin truck. Upper and lower control arms won't either. Torsion bars are all different lengths.

    Power windows

    My FSM barely mentioned this option and it isn't in the wiring diagram either. If you have the wires from the door you should be able to cobble something together to make it work. I put second gen 200sx electric windows in my 620. I used 70s GM electric door switches.

    You would think so after all a larger displacement engine is using the same amount of air as a higher revved smaller engine, but Bogg Brothers page on the Ri swap said the jets were enlarged for a larger displacement. Maybe they were borderline lean on the smaller displacement? If/when I go this route I definitely will have a wide band and take it's readings as law.

    Air fuel. It's not under any load just revving it up.

    Brakes

    It's spongy because the larger calipers need WAY, WAY, WAY more fluid volume to work them. You need to push the pedal farther to push more fluid. D21 Hardbodys use a 1" master, yours might be 3/4"? For this you would need a larger diameter master but this will mean more effort to push it as the 'you can't get something for nothing' law would apply. I would use this opportunity to replace with the dual master from a 620 that comes with a vacuum brake booster to help with the effort. With a single master ANY leak compromises the entire brake system. A dual master will always have either the fronts or the rears still working

    Donk.... maybe wagon wheels..

    I'd like to have a starting point for 2.4 liters.

    It's hard to get good readings unless actually driving it under continuous loads. Only idle mix would be accurate.

    KA24E Donor Mileage Too High?

    If the engine and transmission are together the starter is probably on too. You just need a battery to turn it over. You do know this is going to cost $3-5K to get done. Don't start unless you have the cash ready. Shops are either expensive or incompetent with dodgy work and why most people do it themselves, but then you need a place for several months, tools and fabricating skills and experience. Many are the owner that didn't stay involved with a swap and it spirals out of control.

    Knock or rattle, either way not good please help me

    When done and still at TDC unbolt the distributor from the timing cover and look in the hole. You should see this... Note there is a large and small half moon that only allows the distributor to fit in one position. If it is not at 11:28 unbolt the oil pump and drop the drive spindle above it. With help re-position it like the picture above and bolt everything together. The timing will not be affected./

    Turn the crank pulley till the first cylinder is at TDC and the timing mark on the pulley is at the 0 in the timing scale. Look through the top hole on the cam sprocket and down and you should see a V or U notch. On the thrust plate behind it is a small horizontal etch mark. The sprocket should be on the #2 hole. The notch should be directly below or just slightly to the right of the etch mark above it if the cam is times properly. It should look like this... If it's wildly out you may be a tooth off so move the sprocket one tooth and see. You should be able to use the #2 hole. Never unbolt the cam sprocket without secureing the tensioner with a wedge or a special plastic tool.
