I have a 98 Honda Accord EX and I want o swap the engine for a more powerful engine. What types of engines should I start looking for. Anything I can possibly supercharge or turbo would be great.

 

Need to check the local laws for what will pass emissions - different states have different laws that can make what you are wanting to do very costly.

Almost all F series engines will take to low boost (~8 psi) without costly internal engine upgrades.

Now the PCM/software to run all of this in your 98 is where it gets interesting and will need to know a lot more before getting into that - again state laws, budget, ect.

 

If you want to go turbo than the engine you have is your best bet, as for more power out of the box an h22 will fit that card better but doesn't hold boost as well.
