with the supra your going to want to do A LOT of preventative maintenance on it so you wont have problems in the longer run.....thats the stage that im in now....it can really add up
I'm going to get a low miles engine with a stock rebuild put into my car for 3500, add the metal headgasket and ARP bolts and studs throughout and your looking more along the lines of 4000 bucks, then I'm converting to r154 5 speed for 600 installed as long as I have all the parts. The parts alone will run about 2,000 bucks. Thats's a good example of the kind of money you WILL end up spending if you want to keep the car and that's not even close to being into the mods I want to do lol.
Like I said just sell it to me.
