I have been trying to figure out what i want to do to my 1.5 liter pro (engine). I have thought about doing an engine swap from my stock 1.5 toa BPT, but all i hear is negative about it. What are you guy's opinion on an engine swap? What would be the best swap when it comes to power, price, and easy to do??? Or would it be cheaper to add a turbo or NOS..... HELP!!!
