If everyone read this they will see exactly the difference between the stock 2.0 and stock 1.8 camshaft.
The 1.8 has 8 degrees more exhaust duration but slightly less lift than the 2.0 camshaft which woudl actually make it worse than the 2.0 camshaft for a turbo applicatin.
The 1.8 cam is not that much more aggressive than the 2.0 camshaft. Its more a case of the 2.0 motor is more restricted with teh intake manifold, longer stroke which makes it a lazier motor. The 1.8 engine with the shorter stroke, better manifold can rev harder and has tuning to suit that.
So I go back to it again - this camshaft is a nice mild improvement for the 2.0 cars for sure, but it is not going to gain a 10 - 15hp improvement and especially not more suitabel for forced induction.
But if the cams are goign cheap and you want somethign extremely mild then it will do a nice job, but if you are after some serious camshaft improvements, then when you compare teh specs to the rest of the RPW camshaft profiles, you will see the difference.
