The aftermarket support all depends how how much abuse the engine can take. The reason the 4g63 did so well is because they could take 400 hp on stock parts with very few upgrades. Thats why I fell in love with the motor. I don't know if this is because they over enginered the motor or what. This happens to be true with a lot of motors coming from the 90s. I don't think the designers knew how to build the motor, they over built it in case it failed.
Developing the motor is very different today then it was in the past. The manufactures want to cut as many corners as possible to save cost, so now they can build an engine to go to just 275 or 300 and have it very reliable, untill you try to overboost the car. The aftermarket justs depends what the new engine can handle. The RX-8 engine was supposed to be the supream rotory engine but that kind of failed when the turbo kits didn't do anything and the supercharger belt system wouldn't work with the cars pullies.

What they want to do is surpass the Evo 9. That is going to be stock to stock numbers. The X may outperform the Evo 9 however I am thinking if the 9 is modded, it is going to dominate the X.

The problem with the audience today is that everyone wants to buy something affordable that isn't going to break. Example is that toyota doesn't make the supra, mr2 anymore. Mazda did the same with the rotory engine, RX-8 isn't a popular tuner car but i definatly see a lot more RX-8 instead of RX-7s. Remember why mitsubishi changed the Eclipse platform, everyone was buying the GS and the GSXs weren't selling at all. I am wondering if mitsubishi is going the same route with the Evo, making cars for the people instead of racing.
Still too early to tell yet. I am kind of scared though.
