Hi. That's the thing. Some days ago, me, my brother and 2 persons more, were in a highway. An Opel Calibra 2.0 16v advanced to us. It has a really beautiful neon lights under the chasis, so we run after it to see the lights. He think we want some challenge with him, and start to run. The problem was when the stupid close us the way. Then the thing start. Two gears down (from 5th to 3rd) at 120 Km/h and full gas. The Calibra has a 2.0 16V, so it's better for the uphill. And it only has the driver, while we were 4 in the car. So he increased the gap. But in the downhill we were fastest, at 240 km/h + or -.
After that, we were thinking about increase the block to the 2.0 from the Williams. We heard that the engine block is almost the same. What do we need?
And other question. What is the ideal diameter of the exhaust pipe for gain the greater power for that engine???
I hope you can answer
