hi there I was wondering what to do now to add power to my cavy i already have full exhaust with header and short ram intake. I have a aluminum crank pulley in my porch don't if i should put it on does it (add power ) or not and how much will it add will i notice it. I was thinking about the the ho manifold and throttle body, but dont know if it adds power or not, and i was wondering about the 086 head is that off of a 2.3 ho also and is that a good power adder and is it easy to install thanks to who ever helsp me this one

Id say go with the HO manifold and throttlebody, it will add a few hp. The 086 head swap will add performance but isnt all that easy. You will neet to modify the head to fit the block and then you will end up with insanley high compression. It is not quite decided if the stock ecm can even take that much compression without the help of hp tuners due to spark knock. The pulley is supposed to help free up power the enigne already has so the more mods the better the gain. You could do the secret cam swap, that is supposed to go well with the HO intake swap. You could port and polish your 2.4 head too, that would be pretty straight forward. Power all depends on how deep your pockets are and how far your willing to take your car apart to build it back up. Hope this helped some.
