This makes the engine a "home-made" one, and the power on paper is no longer valid and needs to be established with a dyno plot. Then just use an e-Manage or something to retard the ignition a bit at the top and set a rev-limiter to, say, 7200rpm and suddenly a blacktop makes a bit less power for the dyno run. Disabling the VVT-i for the dyno run might also do the trick.

If only the 20v cam covers looked the same as 16v - there wouldn't be any need to actually register the new engine..

i cant believe you have to go through that much trouble to get something like 20v registred legally. if i drove my hachi to mot w/ a 20v inside.. heh, hez never even seen a 4ag before, letalone the blacktop. here they dont even check the engine number.. its all up to the judgement of the MOT-guy. somebody here even passed MOT w( a BMW e30 318i (and had m50 2.5 w/ near 200 hp. but in that case the "blue envelope" happened. =) here you can have anything under the hood, as long as it looks fairly stock. (but if you paint the cam covers red or something like that they wont let you through. and you might get a fine for having a flashy "tuning" object on your car) stupid law.
