in my94 ex i originally had the d16z6...i loved the motor...but i blew it up...and now that i have it apart it has way to may things wrong for me to rebuild it...the tranny that was with my ex was great to but i could tell that was on its way out too...so i picked up a wrecked hatchback with the d15b7 which is the 16 valve non vtec...what i didnt know was that that car originally had the d15b8 in it...which ony had 70 horsepower....so this hatch that i picked up had a motor swap....the motor only has 80k on it and runs great and supposedly has 105 horsepower, but with the tranny and ecu that i have its super slow topping out at only 105 mph!...what should i do? new tranny and ecu?
