Between me and you I just need to know a few things, when I make this header, theres a good chance that its not going to match up to your exhaust right now because my header isnt the same as the pace setter obviously. Second of all, the header that im selling isnt going to be a direct bolt on for people who just want to upgrade the header without doing any work to the rest of the exhaust. This is quite obvious, but the stock exhaust will be too restrictive to see any performance gains from the header im building. To get maximum performance you will need a good Catylitic Converter, and 2 1/2" smooth bend exhaust, preferably with a good flow through muffler. As soon as spring comes around you may see me sell full mandrel bent exhaust kits for these cars in the neighbour hood of 600 or 800 including the header.
Ive done the research and looked into the design of a good header for our cars, short runners, smooth bends, and a good collector after about 12" of tubing will give the maximum performance. Other designs that would work good are a 4 - 2 - 1 but in order to do so the header would have to be longer and from that you may loose some performance. In larger series headers for motors such as the 2.2, the best headers are 4 - 2 - 1 but are long, they go from 1.5" then to 2" then to 2.5" then to 3" exhaust. In our case we dont need anything that flows nearly that much.
For you guys that are building race motors with the 1.5 si, its going to be hard to get 150 hp, the header built by me will more than suffice to your needs. Anything more than that you are looking at a turbo and in that case, my header cant be used. Turbo headers are typicaly ram horn style and there wont be that much of a market for a 1.5 turbo car because time spend can be spent on a b series swap.
The idea for this header is for guys with the 1.5 that are still looking for some performance gains. There is no market for performance stuff for these cars so for me to spend hundreds of dollars on dyno runs is rediculas. In the long run i may sell a wopping 15 headers in 5 years, now where does that get me when i have to spend *x* amount of dollars on research for the "perfect" length of header. So in order for this to be worth my time at all and maybe make a tiny bit of money im going to essentially copy the best design from other honda motors to build a good header for these cars. The have done the research, they know that these headers work, and infact il know it will work just as well. I really hope i can get this header for sale as soon as possible so you guys can get these little cars to go just a little faster, because thats what its all about. I work for you guys because i love all the guys on this site and ive always loved these cars. I have alot of passion for this site and these cars, i hope that i can always offer you my services aslong as this community is still alive.
Im gonna throw out a number for the header and I hope i can do them for $200 but we will have to wait and see.
