Yes and no. The NATO/USAFE E3Bs should have TF33-PW-100 engines producing 21000 lbs thrust(1), not JT3D engines which produce 18000 lbs thrust. The JT3D engine is used on the 707-320B (2) which is the basis of the E3B. An RAF, FAF or RSAF E3B should be using CFM56 turbofans producing 24000 lbs thrust. A suitable CFM56 engine is available from the JSBSim site(3). I'm attaching my stab at a TF33 engine, basically the JT3D with different thrust, tfsc and bypass ratios.
