If it`s a 18r or18r-u I wouln`t consider doing it unless you got a trailer "welded" to your rear end. They got torque ,but are heavy
workhorses. If it`s a 18rgu twin cam it could be fun but don't think it will be for free. You will need a diffrent gearbox , driveshaft, diff,
enginemounts and you will probably have to do someting about brakes and suspension. Then comes the job of making it legal..... :kiwi:
If you still want to do it, the best of luck to you. If you are looking for a cheap, easy replacement , my advice is to look for a K series.
