corolla turbo Posted November 19, 2014 Share Posted November 19, 2014 (edited) Hello, My original header is blowing. Now i want to put in upgrade one. My engine is completely original only new sealed. Waht Header would be an good upgrade? whatched At kameari but they told me the Drag header is not good for my standard engine. I searched more and found "Pacesetter Header" and "Hitech Header". What one will be best? Hitech gives more power? or is this only kind of replacement? Fom ebay i bought long time ago Cheap Haeder looks like Pacesetter, but there is a sticker on it, Made in Mexico. This doesnt fit my 280zx. Htink its form earlyer Z. what kind of header i should make. In germany is nothing available so i have to build my own one planing Primaries 45mm and 2mm thickness. Is this ok?

malibud Posted November 19, 2014 Share Posted November 19, 2014 MSA sells a good ceramic coated one. no sense in reinventing the wheel by building one that would hard to get a tight fit.. Quote Link to comment Share on other sites More sharing options...

corolla turbo Posted November 20, 2014 Author Share Posted November 20, 2014 (edited) i searched a little and found a thread about "header math"....there are some good links posted. What Outer Diamter gote pacesetter heades? at the links i found some calculation...i should use 38 or 40mm ID tubes for my OEM engine.Because max torque ist 4200rpm. Streetcars are normaly used in low and middle rpm. so the header should work in this RPM range until 5000 at best. With too big pipes i loose NM at low rpm. IS THIS CORRECT?...and it seams to be good idea using longer pipes? Edited November 20, 2014 by corolla turbo Quote Link to comment Share on other sites More sharing options...
