As you can see, H22 just has more upgrade paths from there. Meeting the bottom end of a H22 with a F22 modded up, is quite possible. But where can you go from there? I haven't found anywhere that has turbo kits for F22. H22 parts and upgrades are all over. After I pay off my Prelude, I plan on getting an H22. Right now I'm trying to only buy parts that would be able to be reused after the swap. Since a swap is quite a bit of time away.
