Well I know that DX is DPFI and SI ar MPFI.

Si weighs 2,291 lbs
DX weighs 2,100 ????

how about brakes and HUB?
....... does BOTH hubs have 26spline count?

sway bar options?.... can i basically bolt on any EF sway bar or is it only that the SI model have the holes & bolts to install the front/rear sway bars?

What does the SI have the <U>most DX don't have? </U>
-sunroof
-rear windsheild wiper?
-cluster with tach ???
- what else?

 

Well i know that all STD came with 4spd vs dx and si came 5spd

also STD seats are plastic/vynle but DX/Si seats are cloth.

 

i have a 91 DX no sunroof has a cluster tach, rear windshield wiper/defroster, DPFI, i would grab the weight real quick but i'm pretty sure its 2100. If my car was here right now i would tell you about sway bars and all that. But from my expirience there's more work involved if you are going to be swapping into a DX... DPFI to MPFI + ECU. If its gonna be a daily driver the DPFI gives you better fuel milage supposedly i get a good 400 miles to the tank. Brakes: front have discs rear are drum. I've just got into the Honda world and actually into gearing the performance... don't know about the spline count...

 

-Well, the Si's have sport interiors with Recaro's.
-All of the 88-91 Si's have painted front and rear bumpers, but only the 90-91 DX's have painted front and rear bumpers.
-The Si's have front and rear sway bars and I believe the DX's don't have rear sway bars(not fully sure)
-The Si has a sunroof
-Some DX's don't have right side mirrors
-I believe the Si's have a different exhaust
-The Si's also have a different gearing in the transmission

I'm sure there are more things different between the two that I can't remember.

 

dx and si have the same splines on the hubs, standard ones are smaller at the hubs. but the splines for the trannies are the same.

 

Thanks guys!


Well I don't really care about seats, sunroof, oem exhaust ect.

All i really want to know is which would be a better canidate for suspension mods such as a small front sway bar, rear sway bar, and my tiens SS.

<U>Would it be accurate to say that:
* any suspension mods on a 88-91 civic hb SI would be a simple bolt on to the DX chassie (springs, shocks, camber kit, sway bars, LAC ect</U>

 

dx do have sway bars

 

bump

 

Si's have the suede in the glove box and coin box... .
I dont think DX's came with a REAR sway bar.

 

DX didnt come with a rear sway bar or the correct rear lower control arms with the sway bar mounting points.

all models however, regardless if they came with a front bar or not (STD, possibly HF) have the mounting holes in the front control arms.

 

I want to leanr more too
