engine bay

Being a newbie, i had to come up with this weird question:homer: I'm thinking of swapping my 4EFTE to 3T-GTE...... has anyone done it ? Are performance parts freely available? will the build be costlier than 4EFTE? Any thoughts? suggestions?

i have to be honest. not so sure if this was to go in the 'engine' section or the 'body' section as i've placed it. i not-so-recently vented my hood and have been loving the look and improved cooling that the bay now gets coz when the rad fan cracks in, you can feel the epic heat venting away...
