420a engine options

Okay so my buddy just got a RS. The car is all show and only has intake and 2 inch exhaust. He does not have alot of money right now but, wants to get some mods on his car. He does not know if he wants to go all motor, turbo, or nitrous. So my question is, what would be some good options for him to go with that no matter which option he choses would be a good mod to start with. Any opinions would be greatly appreciated. BTW when he said he wants power I told him to sell it and get a gsx lol.

I'd tell him again ;). If he doesnt have much money, none of those options are going to work for him. All motor power takes shit tons of money, turboing can be hard and finding parts might not be fun, nitrous is expensive and if he doesnt know what hes doing can get him or his engine killed, and I just plain think superchargers are gay. Definately sell the RS/GS and get a GST/GSX. If I had to pick, I would tell him to turbo it.

He pretty much needs to decide which route to take, because many parts would be a waste and are not interchangeable if he goes turbo, etc. Tell him to save his money, and once he has enough to do anything major, remind him that he should sell his RS and buy a turbo DSM to begin with if he wants power.
