that's at the crank, rwhp would be 10-15 hp. depending on transmission & tune.

the six is really hampered by the intake more than the exhaust, and it has a LESS radical cam than the 94-98s.

The more air you can get into the cylinder, the more power you make.

With the 1.8RRs, you increase the lift a pretty good amount, and a little on the duration as the leverage opens them a little faster.

They're cheaper at

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion. Jer 22:13, 15-17
