From my introduction I said I was a BMW guy and almost every different cars shift lever can be taken out and put back into another car...Meaning: I have a 2005 Z4's shift lever in my 1991 318i.
So I'm a "driver" kind of guy, don't care really how fast I go just like to feel connected to the car.
I talked to the dealership and I dont think he knew what I was talking about so he gave a bad answer.
I'm assuming that the Mugen and the SI have a shorter throw lever then the LX. Putting how many gears you have a side, Can I put a Mugen's/Si's lever in my LX? Does anyone have the numbers on the different levers such as the possible decrease from going to the LX to the Mugen or SI?
And Please let me know if I'm looking or posting in the wrong place but I see a ton of stuff for the older Honda's and some good stuff about the SI's in this subforum (2006-current) but not much about just our regular civics. I know mine isn't an SI but I still want mine be a well performing car.
Also is there a website that shows the inner workings of our car? EX:

they already make short throw shifters for the LX/EX/etc.

Thanks and sorry for the dumb question.
So what about that website? Is there one that breaks down our car?
EDIT: thanks for the website, I hadn't found a quality one like that yet.

i think the op was trying to put a mugen si/ si shift lever into an lx.
Yes it can be. The Mugen one (if you can get your hands on it) is around $185. The Si one is around $45, and the LX is around $45 also. I noticed they both had different part numbers and the LX one had a different part number then them all.
LX: 2318617
Si: 2600249
Mugen Si: 4890855
LX: 2318617
Si: 2600249
Mugen Si: 4890855

Well I was thinking that our cars had a lever w/ a fulcrum attached but the piece that RICO has let me know about looks like an entirely different setup. (also means I have to learn how are cars selector rods mechanisms work)
Would it be a big difference if I went to the SI or Mugen lever compared to the piece RICO showed?

IMO I wouldn't use anything but a OEM Honda shifter. Aftermarket shifters aren't the quality or built by Honda. I know on the d-series and b-series trans, short shifters would eventually lead to broken syncros and grinding gears.
Actually I think he was just trying to get a shorter shifter in his car than the one he has stock. He probably preferred to stay with Honda...which is fine....but there ARE other alternatives....hence my post. And I'm pretty sure the aftermarket SS kits provide a shorter throw than even the Si shifter does. I don't know how the Mugen shifter compares to the Si shifter though.

I'd like to stay with Honda stuff..so if any warranty things came up I'd be alright.
Here is a picture that might help clear some stuff up. Do our shift levers look like this?
If so it should be just an easy process to put the Mugen's or SI's into my LX..I guess thats were an exploded picture of the shifting mechanism would help.

i think there might be some confusion here.
first of all, for pictures...try majestic hondas website. they are also a really solid source for parts, averaging 25% back from retail.
i got this pic of the LX shifter and associated parts from there. incidently, the pic for the Si, and the parts list...is the same!

OP, the OE shift throw is dictated by the little nub on part #1. if you make that nub longer, the throw will shorten up. the actual lever doesn't have anything to do with anything except height. you could take some material out of the stick to shorten it, but i don't suggest that. no need in having the shifter further from the wheel!
so, yeah, the shifter in our car is typical of cable-actuated transmissions. it's a lever, attached to a consolidated rotating pivot point, and from that pivot point there is a nub to which a cable attaches. it's not the traditional stick/pivot ball/exchange rod attachment.
so, the question is compatibility between the models....as far as i know, you could ideally take the entire mechanism (part #1) from the sportier models and change it, but, the only option that makes sense to me is just getting a comptech type adapter, like the corsport. in all honesty, i seriously doubt anyone would know (in terms of honda service) that you added that piece. i had my wife's 3rd gear issues solved as per the TSB and they would have never guessed that i had the comptech piece in there. it's just so minor, even if they did, it would be crazy for them to think anything of it.
good luck!

Alright thanks for clearing that up. Its a VERY different setup and I agree with your post.
I'm a DIY'r but like to have all the info I can before I perform something I'm new at and am glad I posted. Thanks again guys for the help.

no sweat. i agree and am the same way. typically, when i get a car, i like to procure the factory service manual. ideally, in hard copy version, but if worse comes to worse, a scanned PDF version. we are not allowed to discuss sources for scanned service manuals. but, i can say that parts breakdowns such as the one you showed for the bimmer, and the one i showed for the civic, can give you a basic idea for things such as what you were looking for.

2008 Si
http://www.hondaautomotiveparts.com/...y5=SHIFT+LEVER
2008 LX
http://www.hondaautomotiveparts.com/...y5=SHIFT+LEVER
if the parts are in the same generation, different part numbers would definately mean different parts. if talking about two different part numbers from two different generations, the part itself might very well be the same, however the part number would potentially be different. a prime example of that would be parts between 92-95 EX/Si and 96-00 EX, esp in the drivetrain department.
also, speaking of the numbers, the part numbers on the majestic honda site, and most other sites of it's kind, are not actual honda part numbers. they do this for obvious reasons. i know you know this gourley, but the OP might not ; )
i believe he could, though i can't say 100%. Either way, it'd cost more than the little adapter and involve quite a bit more labor, unless of course he was doing bushings too. in that case i believe he'd have to remove the level ***'y anyway. OP, check out TWM's unit too...they make very nice stuff http://www.twmperformance.com/shorts...rtshifters.htm
but i agree with rico that an adapter would definately outperform a stock si assembly change in an LX (assuming that change is even possible) i have the comptech piece, which i believe is what the corsport is modeled after, and there is a definite difference between it with and without the adapter. i think it's pretty much a necessary mod...just like shifter base bushings and rear engine mount inserts in my mazdaspeed3.
my question is...
i looked on king motorsports page, and i didn't see a mugen shifter assembly for the Si. does anyone know the actual differences, physically, between what comes in a mugen Si shifter assembly and a standard issue Si? Or, a less scientific question would be, how much shorter is the throw in an Mugen Si vs. a standard Si? Just curious why Honda didn't use an adapter considering how adept they are now at cutting corners and saving money. Atleast in this case, if they did use an adapter, the consumer wouldn't get screwed like most of their cost-cutting moves ; )

Yes I know what the guy said....I don't need it BOLDED and slapped in front of my face again thank you. 
Sometimes you have to look a little deeper than what's in front of you. He preferred to stay with Honda, but in the event that they are not compatible with each other I offered him a better alternative. And even if they are compatible, aftermarket is still the better alternative anyway. He's going to spend ALOT more money doing that type of switch than by just going with an aftermarket SS setup...and for what? Just because he's switching levers between model types doesn't mean he's getting a true short shifter...which I believe is what he's really after. It might be a hair shorter in the overall throw, but only Corsport/TWM's short shifters are gonna give you a significant improvement in shifting distance.
