Replica Header Test
« on: December 06, 2011, 09:26:21 pm »
Here's a header test that was performed on H-T. Ground clearance rating for each header was given also. The motor used was a stock ITR motor, and the chassis was a CRX. Props to MikeySpec for doing this test.

Quote from: MikeySpec
We were given an opportuni ty to test out the lastest popular budget headers for the Bseries recently. All but the Skunk2 Alpha are designs that are replicas of the real deal.
 
 
 
Our test subject is a sexy 91 CRX SI with a stock 98 Spec JDM ITR Swap. Big thanks to Mickey G for letting us use his car.(Green CRX)

 
 
Mods include a Hondata S300 and an intake. We baselined using the OEM 4-1 header and used our 3 inch exhaust dump for every header.
Our test subjects are
OEM 4-1
RMF narrow
Hytech Small Tube
Skunk2 Alpha
Toda Replica
SMSP replica
 

 
 
To make the exhaust install and make everythin g easier we went ahead and hooked our 3 inch dump to the car. Each header is tuned for consisten cy.

 
Here is our baseline using the OEM 4-1 98 Spec Header

181/132 Pretty much what a stock ITR puts out.
 
Next up was the SMSP replica. Ground clearance is sweet, the design looks smaller and construct ed much different from the real deal B19

Red Line is SMSP Replica / Blue Line is JDM ITR
 
Next up is RMF Narrow Replica. Fits nice, ground clearance is decent.

Red Line is RMF Narrow Replica / Blue Line is JDM ITR
 
Next up is Hytech Replica. Fitment is good, ground clearance is rough.

Blue Line is Hytech Replica / Green Line is JDM ITR
 
 
Next up is Skunk2 Alpha. Fitment is good, Ground clearance isnt the best, construct ion is great for the price.

Red Line is Skunk2 Alpha / Blue Line is JDM ITR
 
 
Next up is Toda Replica. Great Fitment, Good ground clearance - Simple and works.

Red Line is Toda Rep / Blue Line is JDM ITR
 
Here are some compariso ns.....fo r the sake of compariso ns
 
Hytech Replica vs. Skunk2 Alpha(The big header pairing debate!)

Blue Line is Hytech Replica / Red Line is Skunk2 Alpha - Midrange character istic was similar when i threw the Skunk Alpha on a big 2.0L
 
Toda Fakie vs. Skunk2 Alpha

Red Line is Toda Fakie / Blue Line is Skunk2 Alpha
 
Toda Fakie vs. SMSP Replica

Red Line is Toda Fakie / Blue Line is SMSP Replica
 
RMF Narrow Replica vs Toda Fakie

Red Line is Toda Fakie / Green Line is RMF Narrow Replica
 
Toda Fakie vs. Hytech Replica

Red Line is Toda Fakie / Blue Line is Hytech Replica
 
 
Here is a cluster of all of them overlayed

 
Each header was individua lly tuned on the same day in a 3 hour window. Results will vary once modificat ions are done to the engine.
 
 
Any questions or suggestio ns on what might work for you please feel free to PM me. Also it'd be cool if you bought your header from someone who knows whats going to work instead of some kid selling parts out of his moms basement.
 
If there is a header needed for a specific setup there are a handful of really good header designers around here. Randy (NAH2B), SSR, ASP, SMSP, Hytech..e tc..etc. If you're spending a ton of money on a nice built engine... ...compli ment it with a custom header.

There was another test on H-T where the Toda (real) beat out everythin g on a 85mm b20v build. That Toda header is no joke.

I had a Toda header on my itr back in '01 and sold it bc I had the opportuni ty to buy a hytech header.

I really regret it bc IMO the Toda was better!  It made more power!  :(
