with 142 whp and weighing 2450 lbs. id say that’s about right. plus it should have a bunch of torque since stock specs were 84 hp and 120 ft/lbs before the engine mods.
parts are actually plenty, easily obtained, and cheaper than hondas. ive been doing some research.

also vovlo can get the parts as well.
also the car comes with a sick brake setup from the “factory” 4 piston calipers up front and 2 in the rear.:number1
that is the exact car im looking at. it needs to have the carb’s adjusted and should get around 30 mpg on the highway. i just i dont know a dam thing about tuning carbs at this point.
