KA24DE

I have looked on google and zilvia and I don't see anyone talking about the eBay 4-1 longtube headers.

I want responses from people who have used the eBay longtube headers that merge under the fire wall, 4-1 longtubes, not the 4-1 shorty headers.

I have used the eBay 4-2-1 headers before and I love the sound of a KA with those but it has always seemed like my cars made more mid-range torque with the stock manifold and not a big enough gain of power on top end.

I have always ran my KA's at 24-25* BTDC with 93 octane, and this is a noticeable power gain as well.

I'm trying to decide if I should use the stock s13 manifold or eBay headers.

All info is appreciated.

I got some feedback on Facebook in the KA24DE/KA24DET Facebok Group and 100% of people said the longtubes are incredibly bad and they threw them away and bought the 4-2-1- headers instead.
