I just want more "TBO" series cars, a heavier weight I6 NA Salloon would be fantastic, a more americanized style pony-car would be nice, 300 break horsepower, 3300 pounds, a midship "TBO" series car would be fantastic as well.
Honestly though, I'd love to see variable timing simulated, vtec-style lobechanges, and all that, but there's plenty more to be done, other than that with LFS
