I havn't got a quote back yet from Superlite, though 550 per wheel for a 13" x 5" wheel sounds a bit steep obviously and it's not something I'm willing to spend. I almost did buy a Metro, but they really don't have nearly as much character as a '76 CVCC, so the extra 10mpg+ wasn't worth it. Though the car doesn't make much horsepower it DOES have a "topend", as does every motor, even diesels. That car can rev beyond 5000RPM, which isn't super high, but it is beyond where I'll be taking it, so yes a cam designed for more torque may be functional, as would high compression pistons and an improved exhaust. Honda built that car for thousands of people and not just me, so yes I think I could improve the efficiency of the car, especially now, 27 years later. I'm new to Hondas, but I'm certainly not to cars. How stupid would I sound if I tried to tell you that you couldn't make an Integra Type R faster because you aren't going to beat Honda/Acura at their own game. Give me a break man, i'm looking for some tips not a damn scolding.
