Nismo280zEd Posted September 29, 2002 Share Posted September 29, 2002 Ok... so i thought i had good headers.. until i took my car to a Z guy.. he was sayn' mine where pretty whimpy... What companys have you guys bought from.. i know there are lots out there that sell for the 78 280z. What do you prefer.. 6-1 or 6-2-1? which has more torque anybody know? thanx ED Quote Link to comment Share on other sites More sharing options...
johnc Posted September 29, 2002 Share Posted September 29, 2002 If its for a street Z then anything sold from MSA is fine. The most important thing with any header you purchase is to port match the header to the cylinder head. The smoother you can make this transition area (including the gasket) the better. The are some rumors out there that a certain design produces more torque and another produces more high rpm horsepower. The real answer is: it depends on your specific engine and its current state of tune. The only way to know is to do back-to-back tests on YOUR engine.

Mike C Posted October 2, 2002 Share Posted October 2, 2002 If you believe the dyno tests on zhome.com then you may want to just put your cast iron manifold back on. Check it out under Modifications for Road & Track. I decided to keep my 240 manifold for my 2.8l motor with triple Del'Lortos. If I ever get it in the car, I'll let ya' know what's what.
