how many of you have dropped a 2.0 lump in your valvers, are there any problems of doing so? any reliablity differences, do the looms plug straight up? any problems with drive shafts, do they knock, pop or fook your gear box? what is the general feeling on such mods, is there any power gain by leaving you standard valver manifold on ya willy enigne? would you reccomend it, also is there going to be long-run pricy repairs cheers Jamie
