Im not sure if this fits in, but I am the proud new owner of a HPI RS4 EVO 3, but it came with the crappy outdated 15FE. I had many options on which engine to replace the old crapper, but I wanted it to have a taste of Redcat. So I just swapped out the old mill for the underdog SH .18 Some may think this is obscure but to us Redcat enthusiasts, its wicked cool. I wanted more oomph from it so i ported and polished it, added a tuned pipe and header and a custom boost bottle. Now I am still a Redcat fan because after all my first nitro RC was a Volcano, which i severely molested into a Volcano that looks like a 1/8 scale with a big-block. Now here are a few pics of my new baby with the heart of a Redcat

Ohh, and if you're wondering, 85% of the car is Carbon Fiber including the chassis.
