I have a 99 civic si........ I just got done replacing my tranny. With the new tranny I also installed a act HD street/strip clutsh, Fidanza 7.5lb flywheel, Skunk2 short shifter and shift knob, Energy Suspension shifter stabalizer bushings, and a DC 4-1 ceramic header. Now it is time for tune up stuff (i.e. timing belt, serpentiene belt, plug wires, ect.) I have been looking at the unortodox underdrive pulley kit that comes with the lightened crank, alternator, ac, and one other pulley. Now I was wondering are these pulleys worth putting on my car. I figured that if im going to be in their anyway for the belts, I should do these also, but was wondering if it is a good investment. I havent really heard anything bad about them and that is why I ask your opinions. Any help you could give me would be great
the pulleys are un balanced and will cause additional vibration in the engine causing additional stress and basicly fucking it up underdriving components greatly reduces their life and reliability... basicly fucking it up its really not worth the 3 hp you might gain.... find that power elsewhere
just for your info a serpantine belt means one single belt runs all accessories such as alternator, Ac, ps, crank, water pump. Honda don't run this. Don't bother with the crank pulley, and dump the DC header kid. Milan
if you want something a little better than stock... nothing if you want to put out some real power they just suck
the design isnt that great they dont flow that great like i said they are fine for an entry level part for the person looking for something a little better than stock but if you want MAX power you really should go with something else
what do you want to spend what do you want to achieve good --- JDM ITR is about $350 - $400 best --- SMSP is about $1000 - $1200 the others i listed fall in there somewhere
Now, what does one use when the JDM ITR doesn't fit without removing a chassis brace and one does not have $1000 to spend on a custom header?
im not too sure on what does and doesnt fit for LS/VTEC setups..... but the Comptech piece is very good.... goes for about $400 the Toda piece is very good but its about $900 HyTech is in the same price range as SMSP but its supposed to be just as good
It's not the motor that is the problem, any 1.8L B series heard fits fine (not sure about a B16 header), it's the chassis. I have a brace that runs from front to rear right next to the header. So I cannot run a 4-1 without collapsing that brace (bad idea IMO) or removing it (worse idea).
the comptech and toda ones are 4-2-1 the only 4-1 listed was the JDM ITR but the SMSP and HyTech are rediculously long so they will end up taking up the same room as a 4-1 JDMilan posted up a link to a new header that looked very promising ill try to find it *** here it is http://www.an-r.com/headers/b-series.html
I saw that link. The header looks awesome, but I would have to move my radiator forward and run slim fans to make room . I didn't know that the Comptech and Toda headers were 4-2-1, I will look into those. Thanks.
the second one looks like it wouldnt take up nearly as much space kinda hard to tell where its routed though... looks way over to the right side ... not sure if it will meet up to the rest of the exhaust well
I am pretty impressed with the reported numbers on the TODA header. It looks like a quality unit unfortunately it costs almost as much as an SMSP or Hytech unit. Pics: http://godspeed.hack.net/todaheader.html
