Difference between an S model and an Si?

Hi,
It's me again. I'm probably going to sound stupid asking this question, but I am curious as to what is the difference between the 2? I mostly see Si models


Thanks,
MizzRobin

^no you're right.

The 2.0S model is stripped down basically. The 2.0S isn't as equipped as the high-end Si, Si ALB or Si 4ws. They dont come with fog lights, Si seats, power anything, no alloy wheels, non-si side mirrors, fuel injected motor, etc. etc. What all Preludes come with is the signature moonroof. That's found on every trim level since 1978.

Here is the models from bottom(frugal) to fully loaded(US):

1988-1989:
2.0S
2.0Si
2.0Si 4ws

1990-1991
2.0S(1990 only)
2.0Si
Si
Si ALB
Si 4WS

oic...that's good to know. The one I bought has everything, but pwr door locks... Would an alarm work with manual locks? or would I have to install pwr door lock motors? Btw...my mechanics were so happy when I brought it in. They started tinkering with it as soon as I got out of the car...lol. They told me it passed smog easily and is running well. They decided to keep it another day. I guess they still want to "play" with it. So cute!



Thanks,

Yah, that i'm confused why Honda did that. Only the ALB or 4ws models came equipped with power door locks on 90-91 models.

The 2.0Si 4ws (1988-1989) came with it as well...

as for adding power door locks, ebay sells those kits. I can do without them ...we only got 2 doors

It'd be cheaper and easier to just find a 'lude with them at a wrecking yard, and steal the solonoids and stuff.

Haha! I know we only have 2 doors, but I have short arms and legs! It's a hassle to have to reach over and unlock the other door. Maybe, I'm just too lazy though! While I was looking around for a 2nd car, I also was surprised that the civic si's of the same yrs didn't come with pw,pwdl, but just the moonroof. I was initially looking at obtaining one of those before I came across my sexy prelude...

I'll need your opinions on this part though. My mechanic took my car for a test drive, and it didn't overheat. The previous owner's mechanic had diagnosed the radiator as being "clogged". Should I change the radiator
anyways, or should I drive it around, and just watch the temp gauge?

Thanks,
MizzRobin

I'd just watch the temp gauge. If it hasn't been overheating for you, who cares what the previous mechanic says, especially if there are no symptoms whatsoever.

better to be safe than sorry, if you see it start to over heat go ahead and change out the radiator, 130$ for a Koyo replacement is a lot cheaper than a head gasket job, plus the radiator is a pretty simple to replace, i did mine in about 10 miniutes

Sure, but by that rational might as well replace everything. I say just watch it. If it ever starts to overheat, go for it, but there's no sense in replacing something that shows no symptoms of failure unless you just feel like spending money.

Yeah, my guys aren't recommending to me to replace it just yet. They had it running in idle that first day I brought it in for a good 45min, and I didn't see the temp gauge go past half. The fans kicked in when they were suppose to also. I live in a city with alot of hills and stop and go traffic. He said that the temp gauge stayed under the halfway pt the whole time. It would cost me about $200-$225 to have it replaced by them, so it's not much. That other mechanic said it would be dbl that when I asked him. No wonder his client wanted to sell her car! I'm glad she did though because I can't keep my eyes off it!

You have checked you thermostate before you go and change out the Radiator?

As for some more differences for the S and Si, some of the Interior panels have carpet for the kick panels on the Si models but that might also apply to which year it might be. Also, fuel pumps are different for the S verses the Si. Lower pressure for the S and higher pressure for the Si.

You turn your steering wheel from lock-to-lock, meaning all the way left or right and look at the rear tires...if they move...you've got it.



you can tell us what year and model your Prelude is though

Also, on the steering wheel you will have a 4ws badge and on the rear of the car you will see a 4ws badge. Plus when you climb up under the rear of the car, you will see a gearbox at the rear end. here's a picture


Hope this helps

Staying on topic, so I've read that the difference between the S and Si are the heads, fi vs carb, but the blocks are the same. So my questions is can I then use performance headers for a Si on the base carburated S model?

OK, mine is a 1991 model with fuel injection, central locking,RH drive, etc. On the rear it reads "2.0i-16".

What engine in there, Kw etc?

Icon6 Re: Difference between an S model and an Si?

well if you all would like I have a S Model an SI model and an SI4ws model prelude. here is the deal I will start with the S model and show some pics ^_^ I am currently driving the S model since the SI model is basically a parts car and my father has my SI 4WS model but I do have some pics of each one.
----------
S model
Basic model and yes it is Carbed

This is your Base model S prelude and this is how it was when I first bought the car. I have actually owned 2 of these the first one was a manual and this one is an automatic, I prefer the Manual this is an 89 and I have done a lot of work to it, Yes I'm a girl and I love wrking on my cars ^_^
anyways there are no power locks, power windows, or power mirrors on this version in fact mine dosen't even have power steering right now HAHA! the line has a leak so bad power steering not to mention it dosent have much Acceleration power with only 106 HP and twin carbed Try getting onto the Highway with this, it takes for ever to get it going but once it gets up there it travels nice its basically a grocery getter of the Preludes or the old lady car.

This is how it looked after I have done some work to it and have cleaned it up Kool hu! I do love the looks of it but its still slow as a snail baught the Wheels from the Junk yard for 160 dollars. Black paint I did myself and yes its the same car as above. now currently all black though.

Here is the most recent pic of it and yes I did the red stripe down it too I have to finish. I had a bad tire on my rear and still had the old rims and tires, same size so put it on the rear as my spare XD till I get more money to replace it.

So thats the S model and yes the Mirrors are different as well as the stock wheels are Steel wheels, most can be changed fairly easily. Im working on changing out the mirrors and hopefully soon swap out the carbed engine for the FI engine in the next car Im going to show you.
Also I will have to get pics of the S engine tomarrow since its already dark outside but I will get one and put it on here

For the SI
Im sure you all know what this one looks like and what features it has and Im sure you all have had a great amount of fun in yours. I have purchased both the SI and the SI 4WS from the same guy and the SI had been in an accident and not really drivable even though it can move under its own power
Heres some pics of it.

the suspension braces ad supports for this wheel got messed up in the accident so it wabbles and clicks as well as I had to totally adjust the allignment so it wouldent just drag this wheel

The interior looks very similar on all the models so I was just going to exclude those pics unless someone is interested, the only difference is seats are not as sporty and lack the lumbar and side tightener knobs and levers since its a basic seat, there is just a blank cover where the mirror switch gose, and below the vents is solid black with no switches. Other than that all the radios are the same the bland climate control is the same along with the digital dash clock is the same, Mind you the SI and the SI 4WS that I have are 88's and the S model is an 89. one difference between the 2 is the Front amber marker lights the 88s have a reflector look thruout the whole thing and the 89 has a clean amber lense with 3 lines running hoizontaly on them. also for the 4WS one some of the logos that someone described above are not on the 88 and 89 versions.
Alright so now for the 88 SI 2.04WS I will show most the pics of this one and another 4ws, the blue one is mine and can't wait to get it back here in about 2-3 weeks so I can start working on it and taking parts off my S model to put on it. anyways here we go.

This is the first 4WS prelude I saw the all black one, The black and pink one is my first prelude and it was given to me. Originally colored Gold Not a fan of gold so Painted it Black and pink ^_^ but thats a story for another place.

The inside door panel with the Power locks switch, Mine has it too just haven't taken a good pic of it yet.

The Steering wheel Not really a good indication of 4WS in this year model, you can lightly see that it says it below the H but in mine I think the horn button has been replaced cause it dosen't say it.

The trunk lid, no indication of it saying 4WS and its the same on my 4WS prelude but I have the Honda badge on the left side as well lol.

But if all else fails this I think is the best place to find out if you have 4WS without turning the car on.
Heres my 4WS prelude to compare a little.

lol my S model in the background beside it

You can just barely see the 4WS logo on the door beam. Its on the black car up above as well, but hard to see. I will take a better pic of it once I get my car back.

The engine, as stock as they come XD
sorry a little Blurry it was a windy day when I took these pics.

The interior. If you look on the door panel you can just lightly see the Door lock switch ^_^ its there.

One thing Im sure noone really notices between the models, mainly the S model compaied to the rest is that the S model dosent have the illuminated ring around the Key holes, theres a ring there but it dose not light up. mainly the ignition key hole on both the SI and 4WS versions it dose light up.

well hope you all enjoy this I am hopping to bring more life into the 4WS prelude and really work on fixing it up.
Heres my main problem I get to deal with on the 4WS car once I get it back.

Dose anyone know of a good welder in Denver area that might weld on this part for next to nothing if I cut it off of the parts car I have?
