So... long story short, my brother had an '84 533i, which he accidentally smashed into a guard-rail, and now it needs to be pulled. But the car was really fast. My book says they were 181hp/195lbft factory. It's also a stick. My Paps was about ready to sell it off with a 528e for next to nothing, and I said "HAIL NAH!" I told him there's definitely a demand for the 533i. I don't mind selling it, but I wanna get it back on the road, first. I don't care for sticks, but I'd drive it for a bit.
Now, realistically, apart from fixing it, I don't want to sink huge money into upgrades, but what are some cheap things for just getting the 533i into good shape. I would naturally do a full tune-up on it, but if there are any little things which can be changed to get it that little bit closer to 200hp, I'd probably go for it.
