Just wondering what your guys input is on this - I am rebuilding my motor [hopefully Sakai is]... but anyway its been stock for a long time and now I might as well upgrade..

So the usual suspects for header choice is JDM R 4-1, but from Steve's reccomendation he said to try something a lil better. What comes to my mind first is Toda, and then I think $$$...

Now I'm not out here trying to make my car #1 HP machine or whatever, I just want a motor thats reliable and I can finally take to the track and not worry about it blowing up..

So anyone have a median btwn JDM R 4-1 vs. Toda 4-2-1..?

Some choices I have found..

- AN-R header [one that looks like a turbo manifold, can clear fullsize radiators
- JG 4-2-1 w. custom 2.5in collector

 

Check out: Header-Tech

 

try to find a used TODA

Yea I wish - they come along once awhile, but I cant wait around for that...

Ill try Header-Tech - gotta search y0!

 

For new look at AN-R and HeaderTech

If you go used you cant go wrong with SMS or Toda

 

i'd go toda or smsp.. just get the best header available, don't save money cause header makes the most out of 3 basic bolt ons - I/H/E..

if you plan to keep your stuff all motor, you'll regret not getting a better header, or you might spend more money in the long run upgrading..

 

When you look at the averages instead of the peak hp, a $1000 header only makes between 1hp and 1.7hp more than a $350 JDM header.

George Knighton and Austin can attest to the benefits of a high-quality header and proper tuning.

I'm sure they know their peak hp number, but do they know their 3,000-8,400rpm average hp, or their 6,000-8,400rpm average hp? Thats really whats important.

 

You may just be putting too much stock in that old header test.
