Now lets be honest the header test might be beat to death. But since half the graphs don't show up and most are after the peak number... I find it hard to really choose the best header for my R. JDM 98+ B18C-R using the stock JDM 4-1. I hear a lot about TODA being right next to SMSP for the best header but then I look at the posting date and think, there has been at least 5 newer designed headers out there. Think Bisi and Hytech were not tested on many of those older test because they simply weren't available. Well for road racing you try to get a killer midrange. TODA is obviously well known for road racing but how does that stack up against today's newer designs? Anyone have some insight? Maybe even a link to a page of a thread I might have missed... and a custom header is not an option here because that is some serious cash.

I need graphs to compare the JDM 4-1 to the others...

 

toda..jun...spoon...they all build cars for road racing..midrange power more than top end...so toda would be my guess...if ur on a budget the "best" might not be for you..spend the money on good cams...use a p30 intake manifold or itbs...

 

TODA only way to go .. from what I have seen

 

So I bought a TODA header today :p. Guess I will be doing the dyno and overlay. Same day, same dyno, with and without tuning.

 

good choice...kingmotosporst make like 240 or more on a 2l and a toda header for a roadracing engine...look around in their performer x test they used a toda header...
