I have a fiero and i dont like the engine- the inline 4. its weak and low revving. has the 5 spd getrag manual. i am unsure of what engine to put in it but my friends have experience with japenese cars and will help me install, but dont want to sway my opinion. another available option is a 4.3L Vortec engine. i was considering the sr20det or a ka24de but have no idea if they will work. can someone help? i see lots of 3.4s/3800s and want something different.
