  • Normally, the 20v and 16v has the same bottom end, so why a different head would make the bearing knock, don't know???

  • I'm still yet to see a 16v 4AGE motor turbo'd stock and make over 160kw ATW in the highveld. Big wow, I can also change everything on 20v motor and make it a strong motor. Google 20v 4AGE motor from overseas and see what they do with this motor.

  • yoh sorry about the quick hands. i'm typing faster that I can think but you can figure out the words. I rather try again.. Firstly what danrsi said is correct. Secondly its just because people dont know how to drive the car. I have heard this so many times and just laugh. Again I say, my car was turbo'd with 0 kms on the clock basically. Still not given up. Car set at 0.6bar boost and with the cold winter this year boosts up to 0.9 bar at the moment, still going strong. Stock original motor. And I know the exact reason why N/A applications are having problems....linked to what I said about how the people drive their cars is beause they don't understand certain things about the car.

  • the reason the 20valve breaks so easy is the parts have been made lighter so that it can rev faster! Alot of people complain about it knocking and normaly this is not a bearing knoch!the vvt puley wears out and causes this to happen.depends on what rpm it has the knock if only on idle its the puley if all the way through its a bearing or lifters

  • it works on the exact same principal as an opel 16v motor compared to an 8valve motor the internals of the 8valve can take the "hit" but dare try it with the 16valve ull be waiting in the Que by SA auto parts to be served LOL!

  • You are right all the way Jo' the 16v's can take the punishment on the other hand the 20 v's top is so weak.

  • I think the 16v is a much stronger motor than the 20v for reasons I can't tell you. I guess the less moving parts the better. Also the 20v valves is much smaller and fragile than the 16v valves. I stand corrected though ?
