The EJ seriers definitely
The EJ seriers definitely came out in 89 and the were Naturally aspirated but they did have turbocharged versions early on and In the mid 90s we had turbo charged versions in the US. In the states I've seen the early ones use 2.2s and then late late 90s 2.5 except small turbos which were 2.0 but definitely alot of 2.5 turbos as well. They come sohc, dohc and they've even made smaller engines like 1.8 and as small as 1.5 in certain markets. But definitely 32 years of ej production. And the reason certain ones have a different rumble is because they came with un equal length headers that's what makes the unique rumble. But now they like to use equal length headers so it sounds like regular inline 4 cylinders. However you can always put a set of unequal length headers on even the fa seriers and it will sounds just like an ej with same headers.
