The 21R engine and the 4DR5 gearbox are not directly compatible, as they belong to different engine families with distinct designs. The 21R is a petrol engine, while the 4DR5 is a diesel engine, which typically means they have different mounting points and bellhousing designs. Adapters might be available, but significant modifications would likely be needed to make them work together effectively.
The bolt pattern is the same, but the 21R engine has 2 locator dowels, which must be accurately marked and drilled on the gearbox, if it has come from an 18R. The bolt pattern on the crankshaft end are not the same, so the flywheels are not interchangable.
the engine reads this because Nissan made a 21r engine, similar to the 22r, except the 21r was smaller, and the head was slightly different. it is often unheard of because it is illegal in the unites states because it doesnt reach emission control that the US requires
The GCF is 21r
On my '84 21R engine it turned out to be the coil after much swapping & cussing.

no it does not equal 21r.4 im trying to find the answer and i know it has 2 be bigger then 21.4 and i know cuz im awesome at math and i've been in a bunch of competition about math so trust me its not 21r.4

The torque specifications for the cylinder head bolts on a Toyota 21R-C engine typically require an initial torque of 22 ft-lbs (30 Nm) followed by a final torque of 43 ft-lbs (58 Nm). It's important to follow a specific tightening sequence and to ensure that the bolts are torqued in multiple steps as per the manufacturer's guidelines. Always refer to a service manual for the most accurate and detailed specifications.
You can find a reliable source to purchase a RockShox Quadra 21R elastomer kit for your mountain bike at authorized bike shops, online retailers specializing in bike parts, or directly from the manufacturer's website. Make sure to verify the authenticity and compatibility of the kit before making a purchase.
OK, this looks like a quadratic equation, which means a polynomial whose highest power is two:-3r^2 + 21r + 24 = 0The general form for a quadratic equation isax^2 + bx + c = 0and the general solution is given by the quadratic formula:x = [ -b +- sqrt(b^2 - 4ac) ] / 2aBecause a quadratic equation is second order, it has two solutions, or roots. The +- symbol means to use the "+" sign first, and then use the "-" sign. It is read as "plus or minus."So, if we replace the x with your r, and the coefficients, a, b, c, with the ones from your equation, we get for a solution:r = [-21 +- sqrt(21^2 - 4 * -3 * 24) ] / 2 * -3When you do the arithmetic using the "+" sign, you get -1 for the first root, and using the "-" sign you get 8 for the second root.So, the solutions are -1 and 8, which you can verify by plugging either of these into the original equation.
Let a be the first of the three number and r the common ratio. Then a*ar*ar2 = a3r3 = 216 = 63 so that ar = 6 Also, a + ar + ar2 = 21 Substitute ar = 6 to give 6/r + 6 + 6r = 21 or 6 + 6r + 6r2 = 21r So that 6r2 - 15r + 6 = 0 or 2r2 - 5r + 2 = 0 2r2 - 4r - r + 2 = 0 or 2r*(r-2) - 1(r-2) = 0 or (2r-1)*(r-2) = 0 so r = 0.5 or r = 2 r = 0.5 gives the three numbers as being 12, 6, 3 and r = 2 gives 3, 6, 12.
