Best setup for drifting...

[NoHachi]

Honestly, if I were you:

I would do the 4A-GZE. But you think it is too expensive and too little hp. Ok.

Next best bang for buck is:
4A-GE 20V blacktop + profi install. 2000E if you beg?

Then once you have money again:
DIY exhaust (600e)
Megasquirt (400e)

Then once you have money again:
TODA cams or whatever brand does something for the 20V. That should be north of 190hp and more or less a wet dream in terms of response and audio-porn. Only non-20V's i've seen over 190hp are the full Formula Atlantic type builds.

What you save by starting with your stock 4AGE you will spend later on on headwork and pistons. Same hp as GZE, but 1000E more expensive.

Money spent on tuning the bluetop I would spend on tracktime, tires and brake pads. Why do you reject the idea of spending money on tracktime? You seem to be having trouble with a JDM sickness called parts-blindness
