I was thinking for a while about doing the 3sgte swap but a few of my buddys tell me just rebuild the 5sfe with some beefy internal work and turbo the motor cause they said i would save more money and it would be a lot easier cause there wouldnt be any wire harness problems and why would i drop down in motor size why not just keep the 2.2L im still undecided so if you could help let me know and thank you!!

its not the size that counts. your friends must not know much about the 3s. and depending on the condition of your 5s, turboing it may only be a few hundred bucks cheaper if done properly and won't be as powerful as a 3s.
