2.0L Inline 6 engine with a torquecurve based on the BMW M20B20 engine
12 configs: 2000, 2000i and 2000ix in both manual and automatic variants and both pre and post facelift
I got the idea for this when I saw that the 2000 letterings are already available in the parts selector in the vanilla game. There was a similar mod a few years ago, I don't know if it still works, I found about it after I finished my own. The engine supports all the vanilla tuning options. The engine can also withstand a bit more RPMs because the cylinders have a smaller displacement.
Pre-facelift (Stock Intake)
Post-facelift (Sport Intake)
