The SR20DET engine swap isn’t quite the popular engine choice anymore, with all the LS1 and RB/2JZ swaps running around. But there’s still no stopping true 240SX enthusiasts who don’t believe in shoving an American pushrod motor into their 240, nor a inline six iron block such as the 2JZ and RB.

Prices have fallen quite a bit for JDM engines in accordance with falling demand, making the SR20 less of a budget swap than it used to be. When you calculate the prices of engine swaps alone, the truth remains that you aren’t truly saving that much when compared to other motors.

This is where having a SR20DET ECU pinout is so handy because you can do the swap yourself.

But they are still easier and cheaper to bolt into your 240SX, something which should come of no surprise considering it’s the very same engine and transmission offered in Japan. You will not need new mounts, a new driveshaft or any shifter mods, making the SR20DET a great bargain engine swap even today.

Tuning ECU’s have also come a long way, but for the handful of enthusiasts still using piggyback controllers, we’re taking a look at the two different types of ECU’s offered in the Nissan Silvia.
