ok any kind of specs i can find on the net all seem to be inconsistent, i have a 83 with a 12a, with a new big exhaust with no catalyic converter and the air pump disconnected, what kind of kW (or hp) should i be getting out of it? thanks

 

Well, depends on who you talk to.

I'm not sure on teh Aust. spec 12a's, they MIGHT have come with 115 hp stock. The US spec ones had 101 hp stock.

A full exhaust system CAN add up to 15 hp!
