16v are much slower
What an idiot. They arent - and until youve owned and driven both for years, like me, then I suggest you take your own views with the large pinch of salt that everyone else does.
The other differences are chunkier anti-roll bars, a slightly higher level of rear brake bias, different rate shocks and springs, lower wishbones from a 19 16V (to make the front track wider along with wider wheels), a Siemens Fenix 3A black box ECU (not just chip) and the lack of electric mirrors, sunroof and stereo control on the original Williams series.
Then of course, there is the engine. The basic design is similar to the 16V, but the Willy uses a crankshaft from a 1.9d engine and is bored out. The head and inlet manifold look similar, but the parts are polished and there are bigger inlet valves in the head. The head also has a resin coating that the 16V does not. The camshafts are also slightly sharper and theres a fabricated steel exhaust manifold (four-into-one). The pistons have thinner compression rings and twin-lip oil control rings. The sump is also properly baffled.
The gearbox uses the first four ratios from the 16V, but has a taller 5th gear, bigger gears, beefed up casing and stronger secondary shaft.
