Boosting your 2.0L 16v Engine with parts of a GTI 1.8L 16V engine... : By Yazeed Madaeen

To get more torque from your 2.0L GTI 16Valve, You can use an air manifold of a 1.8L GTI 16 Valve as long as it is wider in diameter, so to gain more air outflow without loosing that precious internal compression of the engine, the improvement will not be felt however if you still haven't changed your double overhead cams with with the 1.8 L GTI 16V camshafts, the later run in shorter ratios than the originals, and it should go without saying that after doing this and to get the best results you should install wider headers to the exhaust system, since you will need the larger outflow for the smooth disposal of the compressed air without loading the pressure of resistance to your piston rings that are already getting enough pressure from the strong car.
