In our last edition of Project Low Buck SR20DE, we stated our goals to obtain a decent amount of naturally aspirated horsepower and good track day drivable reliability from an underdog plain jane SR20DE without braking the bank. Fulfilling these goals would also create an engine with excellent street driving characteristics as well. All of our engine work will be done on the cheap with a tight budget in mind but with plenty of attention paid to minor details that can really help an engine live under the stress of track day pounding, perhaps the most abusive environment that a grass roots enthusiast will subject his engine to
The SR20DE engine has been Nissans workhorse performance 4 cylinder for more than the last decade. Originally introduced in North America in the Infiniti P10 G20 and in Japan in the PS13 in 1990, the SR20 was designed as a performance motor from the beginning. Later in 1991 the SR was dropped into the venerable B13 Sentra SE-R and NX2000. The SR20 was carried over to the B14 200SX SE-R in 1995 and the B14 Sentra SE in 1998 as well as the P11 1998-2001 Infiniti G20. The 2000-2002 B15 Sentra SE was the last application of the SR20DE in North America.
