this thread is bad enough without all the bullshit being added by certain rollaclub members who have asked similiar questions before they got their p plates, and then crashed a ke55... also suffering from poor grammar and spelling at times too.
for f@$ks sake, give the kid a break, we have all had dreams that may or may not be realistic, so if anyone feels like going off topic again, or displaying appalling rollaclub spirit, be warned. :fuzz:
as for a reply to the OP, sadly making your ke30 a drift car and street legal will be a major challenge.
first you will need reliable big power, whatever motor you choose, you'll need to budget around 1000 bucks.
then you'll need to make your car handle, this will involve custom suspension, as not a lot of aftermarket stuff for your car really exists. allow about 2-3grand
limited slip diff would be your only legal diff choice, again 500 bucks minimum.
after you've done all this, you probably want a race seat 300 and rollcage 800ish.
all the best with your project, it's yours to do with what you want, but remember even though this community can sometimes be immature and offensive, a lot of us have been down the path you wish to go, and some of our advice could save you some headaches and money.
build it, then stick it to em...
