Here's why:
* The 1991 MR2 came with two different engines:
* 1.6L 4A-GE (naturally aspirated)
* 2.0L 3S-GE (naturally aspirated)
* Swapping engines can get complex:
* It depends on your desired power output and budget.
* Some engines require extensive modifications to fit.
* You'll need to consider the transmission, ECU, wiring, and more.
To help you get the best answer, I need some information:
1. What's your goal? More power, reliability, or a unique engine?
2. What's your budget? Some swaps are more expensive than others.
3. What's your mechanical skill level? Some swaps are more difficult than others.
Once I have this information, I can provide more relevant suggestions.
Here are some popular engine swap options for the 1991 MR2, but keep in mind these are just examples:
* 4A-GZE (supercharged): A relatively straightforward swap that provides a significant power increase.
* 2JZ-GE (from a Supra): A very powerful option, but requires significant modifications.
* 3SGTE (turbocharged): A great option for those seeking more power, but it also involves a lot of work.
* K-series Honda engine: Popular for their reliability and performance, but require custom fabrication.
Remember, before you start any engine swap, it's crucial to do thorough research and plan everything out carefully. It's also a good idea to consult with experienced mechanics who have done similar swaps.
