^ Also will make you bolt in floor pan fall out .
In all seriousness but, its not worth the money. I've been through all this at the end of the day it better to to just wait it out. (buy a turbo engine and modify it while ur waiting)
also don't just think "performance" means powahh, look into coil overs (i have tein HAs in my 33 and it handels like its on rails), big sway bars, strut braces, sticky tires, or think about the other components that are going to.let you down later on with more power, think gearbox clutch diff etc.
Goodluck
