Your def def gonna want to do a swap since you have a N/A motor right now. The best bang for the buck and the best motor to swap that will allow you to achieve your goal is a full STi long block with the 6spd transmission. The swap is not cheap though. You can get the full STi long block motor at a decent price threw many performance shops and online sources (I think they run between $3k and $4k). But the 6spd transmission is expensive (usually around $4k for the whole thing, inlcuding axles, cross members, etc.). This is def. the way to got hough if you want 300whp and possibly more in the future. You could always do the STi motor with a WRX 5 spd to save money but you get what you pay for meaning the 5 spd is not very strong and your not going to be able to really every launch the car and will have to be careful when driving hard because the 5spd likes to break under a lot of power. The 6spd on the other hand is basically bullet proof so you would be more then safe driving everyday and driving hard and even launching the car with 300+ whp. But just doing the motor and tranny swap your still not going to be at your 300whp goal, you will then be at the same power as a stock STi and will have to do more bolt on mods and fuel mods to support the amount of power you are after.

Your best bet is to do some searching, because theres tons of people that have done this swap in the Baja and tons that have done it in the WRX, the STi motor and tranny are the most swapped for these cars. So do some searching and you will find some good sources for the motor and tranny and find a list of all the other parts you will need to buy to make the swap work. Also read the stickys at the top of each section, especially unabomber manifesto, they will give you tons of usefull info and help you understand what exactly you can do and better help you understand what is needed to achive your goal. Good luck and happy searching!
