first of all, hello guys, i've been reading the articles from this site and i must say that they are pretty impressive and helpful.
i own a civic si 1998 with a b16a engine
i currently changed the intake/filter and the exaust. also removed the cat but with stock pipes. well, i must say that i am pretty satisfied with it's performance since i am holding on pretty well against an fto 2.0 v6 mivec.
first and second gear i am in front of him, on the third gear he comes next to me and on forth gear i am loosing ground.
i am planning to do another upgrade on my car. at first i was thinking of changing the cam gears or the flywheel or get a vtec controller. but now i might go for headers which i think it's the best thing to do.
i did a small research on headers and i am between 5zigen and vibrant ( http://www.verociousmotorsports.com/Shop-by-Category/Honda_Headers-and-Manifolds ) headers. i can't go for spoon/mugen/jun... due to low budget
and they told me that those are the best headers for the money i am planning to spend.
but i can't decide whether to get a 4-1 or a 4-2-1.
from the articles i read the 4-1 gives you more power at high revs and 4-2-1 at low revs and the 4-2-1 is more appropreat for street racing instead of the 4-1 which is for drag.
well... i need more torgue... but i don't know which one to get.... at a race it's logical to have a low gear so that my revs will be high, close to vtec, so the 4-2-1 will not help me that much (i think) and when i change gear my revs are still high (example: if i change from first to second my revs will be at least at 6k with the second gear)
so i don't know what to choose. the thing is that i heard too many good things about the 4-2-1 that i convinced myself to get one of those... but since i don't want to regret it, i thought it would be better to ask for advice.
by the way, i heard that the 4-1 is not that good at low revs... but will the performance of the car be worse than the stock ones on low revs?
also since i am gonna change headers, i'm thinking of changing the pipes to a 2.5 inch. the headers are 2 inches but i can also get a 2.5 convertor but i don't know if this is wisable to do it.
(by the way, i am not planning to turn my car into a rocket since i am planning to keep this car. that is why i don't wanna change things on the engine, since it lowers the longevity of the car, for now)
thanks in advance
