Got a 00 civic si turbo, stock intake manifold and i just bought a 70mm bbk throttle-body. should i port the stock tb and port the end of the intake manifold the same as the tb? or buy a jg edelbrock and port the end to 70mm to match the tb?

 

just port match, no polish... if you got the money, get the edelbrock, bigger plennium and fatter runners=happy b16

 

WHich is more expensive? I would think the edelbrock will be better in the end even if it costs a few more dollars. I would go with that.
