Im in the market for a nice header for my b16 but not quite willing to cash out 500 for s.p.'s toda replica yet just in case I go to a 2.0l motor down the road were Ill just get a hytech rep for cheap.

what are some of my other options for a decent header, Im running blox B's with a itr intake mani and 70mm t.b. with 2.5" exhaust. currently have a 4-1 header with a small collector.

post up what you've used before and had good luck with on a 1.6

 

up I know b16 all motor setups are for weomen and children but it also makes a great daily motor for my car


I really think my tiny collector is holding me up.

 

The DC JDM 4-1 header is what I used with good success on my old B16a. The old Edelbrock with the 2.5" collector mod if you can find one anywhere is good as well. A 4-1 header is ideal on a B16a or something similar to Toda.

 

ok, well the header im running is just one of the ebay b16 headers that go 4-1 and the colector on the bottom has the runners going in side by side kind of like a itr header. I just modded it today to have a 2.5" collector and felt a pretty nice difference over what it was. had to retune it because it went from 13.2afr at wot to about 13.8-14.0

 

Im also thinking about doing a 2.5" cut out on the car because with out the exhaust hooked up it seemed to pull a good amount harder.

 

That AFR change is a good sign.

 

ya thats what Im thinkin. it def seemed like it opened up quite a bit. Im still used to having a 350whp 300ftlb turbo car so its really hard for my butt dyno to tell me if its fast or not, just beat a h22 prelude from a roll by about 6 cars so Im thinking its doing Ok.

 

I just put a stock itr map on my s300 and OMG its soo much faster, I don't understand I tuned it with a wideband and everyhing and this map just pulls soo much harder.
