I did some poking around to determine just what the maximum speed of the Integra Type-R would be in a street-driven nature. Now, all of my calculations are based on the assumption that the car is running the stock gearbox (which I think is common in this type of...'situation'). I'll also use the standard 15x6 wheels with stock 195/55R15 tires (which wouldn't hold up at 180 mph, but let's ignore that for now).
I'll use the gearbox specs of the B18C5 Acura. With this information, we get a value of 13.39 mph per 1000 rpm in 5th gear. At the 8500 rpm redline, this gives us a maximum speed of 158.86 mph.
So, without changes in the gearbox and tires, we're already WAY below the 200 mph mark, without even worrying about the engine. So, let's see what happens when we go up to a larger tire. I smell a bit of Uncle Ben, so I think I'll go ahead and use 18" wheels. So, with 215/35R18 tires, we end up at 162.11 mph. Hmm...still nothing.
Okay, let's do something weird. Let's throw a 3.800 final drive into this beast. With the 18" wheels and Altezza lights, we should be at 225 mph easy, right? Wrong, 187.70 mph. Well, at least we got to 180 mph - assuming you can put a 3.800 on it (not sure if this is even possible). Plus, at that drive ratio, acceleration would be...hideous at best.
To sum up, assuming one thing: the standard transmission and final drive on a MY01 Acura Integra Type-R, no amount of mods will allow you to reach 160 mph, let alone 180 or 200.
Okay, I'm done being a butthead now. If you can show us what gear ratios that 200 mph Type R is running, then we'll have something to go on.
