SMH, I'm sad to see you say this. Pistons can/do add power Banker, you know this. They add power, just slightly tho. If you use higher compression you actually get more hp and a little torque. However, the rest of that is true, valve springs are only good for handling more boost or higher rpms to keep from valve float.Pistons and valve springs do not add power. If you're looking to keep it n/a, replacing your pistons is useless. If you're an 07+, cams aren't worth it either as it will cost you quite a bit of money to get them to work properly and more money to get bolt ons to get the most out of them
That statement is completely true, and being around it all the time it's almost second nature to know the technical stuff that is needed when building high HP machines. Not many regular Joe Blows off the street can just sit down and build a 700+whp machine on their own. Most people that do that have done countless research. Building an engine isn't just as simple as tossing stuff in it (tho to people like me who do this every day it is lol). There is a lot of detail that is put into properly building an engine like that.banker said they didn't add power.
You agreed with that.
While listing VF as an issue, you went with the not adding power...when in fact they can if the current setup is floating.
I don't build race engines for a living, but I've been tinkering with cars since I was little. It's not rocket science if you've been around it most of your life.
I have the adapter plate and throttle body your looking for up for sale in the classifieds section for that 2.4 manifold. If your going to stick to NA on your 2.2, you dont need to waste money on internals. The intake manifold, long tube headers, and throttle body are a good choice. If your 2.2 is a LAP and has VVT then Hptuners and a custom tune is also another good investment to make power, as you can gain power by having a competent tuner adjust the VVT and timing accordingly.
