Toyota Supra MK3 900 + HP !!!!!!!!!!!!!!

[Supra Saiyan]

I got a fresh 7m-gte =), for beginners and is it really hard to just get past 300 HP like most people say it is? and how much would it cost for everything?

Not hard to get TO 300hp.. The reason you can't get PAST it is fuel cut.. You need the proper setup to by pass the fuel cut.. 300hp (right around there IS FUEL CUT) I would say 400hp is where you should call it quits for a stock without upgrading the bottom end.. (Assuming you already have done the top end..)
