My most faithful recreation of the non-turbo inline 4, SR20DE, found in Nissan Silvia/240sx series of cars. I used the real specifications and measurements of the engine components wherever I could. This is my first attempt at making an engine and I think it came out great. I may update this as I learn more so be on the look out for potential updates.
P.S. Thank you for a 100+ downloads! I really didn't expect for this to grow this quickly!
UPDATE v1.1: Redid the timing and got the horsepower up to 151hp which is correct for the SR20DE, Increased starter rpm so the engine, starts faster, slightly reduced idle rpm, reduced ignition cutoff time at redline, and added in the newer intake/carburetor system into the engine.
UPDATE v1.2: Added custom transmission with stock gear ratios based off the Nissan Silvia S15 production model, Added car dimensions such as size, weight, drag coefficient, tire size, and rolling resistance also based on the Nissan S15 model. Note: it still seems to be down on speed even though horsepower and torque are adequate. I suspect it has to do with final drive, and if that is the case, that will likely be the next update.
The node is sr20()
Hope you enjoy it!
