Does anyone know if there is a difference between these two headers? I want to be sure of the one that is on my car; is there a way to tell the two apart?

 

anybody?

 

Don't quote me on this...but isn't the ITR collector bigger than the CTR.

 

if this is the case, then I am safe, I measured the collector before I installed the header. It was 2.5 inches.

 

CTR didnt come with a 4-1 header. But just a reference, ctr and itr use the same block, but the ctr is destroked to 1.6.

 

Ok, today, I went to get dynoed. I put down 183 whp. I am running the following:

cai/jdm4-1/greddy evo
toda b's
cam gears set at +5,+2
jdm itr pistons
mugen program
field sfc vtec at 6800 rpm
honda 280 cc fuel injectors

my power output is low for the set up. I should be putting out around 190. When I first installed the pistons, my mechanic set the fuel pressure really high to guard agains detonation, I was running really rich for about 6 months. The dude tuning my car knew this and suggested that my cat could be clogged up form running that rich. Today at WOT, the motec was reading around 13.5. What do you guys think? No, I don't want a turbo.

 

anybody have any ideas why I am not putting out more power? I am really baffled. any help would be appreciated.
