Hello everyone, I am Marc and I live in Orlando. I am currently shopping for a new car. I decided to go for a 1998-2001 Prelude. I was wondering what was the difference between the SH model and the other one. Is it just Vtec? Anyways I'll most likely get it in 2 or so months. I am looking to get a 5spd Pear White.. I am only planning on doing basic mods. INtake, exhaust, short shift, and posibly carbon hood and new front bumper.... Anyways thanks for the info and also if you guys know of any good online place to buy stuff from please post them for me.
Thank you,

Marc

 

well sh has leather, spoiler, and atts (searchforinfoonatts) and all sh are manual. Nice color choice, but do get sideskirts and rear to line up right if your get front bumper, the lude looks alot better dropped as well. You can try mmrusa.com, nopionline.com, visracing.com, kingmotorsports.com to name a few....... welcome

 

thank you.

no prelude was offered leather... but yeah main difference is sh had a spoiler and atts. all preludes came with the 2.2l vtec..

btw how much you looking to spend? I have a mint condition 2001 pearl white prelude for sale:
5sp
no door dings
factory lip kit all the way around
23k mile
syn oil every 3k
19,200 stock with factory lip kit.
virgin motor NEVER modded, I just put on a k&n drop in filter though...

yes there is, the Canadian model. but not in the states, definitely not in a SH.

also, the SH shift ***** are different from the base model. and on the SH, the factory side skirt and rear lip are color matched to the rest of the car. oh yeah, SH rims are different also.

not in the united states...The guys from florida i doubt he's buying a canadian model. Lets not get into the whole leather debate..

 

as petroguyx said....they do come in leather, my SH is leather as well as my friends SH is leather.

 

the engine is basically the same regardless of whether you get an SH

unless handling ability is very important to you, i wouldn't bother getting an SH... on average they are 2-3 thousand $$ more. unless leather is worth it to you, don't bother (anything else such as spoiler you can get installed for less anyways).

 

I probably could aford the 19,200 but I think I'm looking to spend less than $15,000. So I'm probably looking more at 98-2000. Id like some cash for lil mods. BTW what does a stock prelude run in the 1/4?

 

stock lude runs 15.4 1/4 mile. +- a few tenths.

i will tell you that if you decide that you could get into more serious mods, that if you get an SH it will be much harder to do things like turbo, SH, etc with because of the ATTS unit.

stock and close to stock, the SH handles better. once you get beyond that, a base with an LSD will handle better than an SH. it all depends on how much you want to modify your car.

 

although not related to topic, but
SweepeR 7...your car looks mean from the front, i can wait for my cf and jdm fogs and lower it a bit.

Keep it up.

 

I have a 1997. I was told there was no leather option. If there was I would have bought it. Maybee it was added as an option to later years.

 

Besides the basic ATTS, leather shift know, Door panel lights, painted lower body pieces, wing, wheels. There are many more differences, the front knuckles are thicker and the ball joints are located in different areas, shocks and struts have a negliablely higher spring rate,front trailing arms are thicker, the transmission casing is a little smaller than the the base, the SH block is a little different which is just a couple of 'coolant hoses' going through the engine oil cooler and location of oil filter. The transmission bolt pattern is the same as the base model and any F/H series transmission and will bolt up to the SH block, regardless of people saying they do not, just do a search under the name 'clendaniel' or go to this fantastic write up- http://ian.clendaniel.net/gallery/noatts-
SH respond just as well as the base to forced induction, The ATTS goes into protection mode once 240-250 hp has been made or exceeded. The SH has a different ECU than the base which includes an ATTS control unit that is interfaced with the ECU. The rear suspension is for the most part the same, Front and rear roll bars are a little thicker. Basemodels will not outhandle an SH, you have to spend a at least a G or two just to get to the level of an SH. SH suspension can be moded just as easily. Hope this helps.

 

Just one more thing Prelude's only got leather from aftermarket sources, or are canadian models. As leather seats were not an option on US preludes due to cost issues.

 

You must be a complete idiot to say usdm preludes do not come with leather, there was three stock shs at my dealership last time I Went, and every one of them had leather.... and so do alot of peoples on here that didnt get it aftermarket.......

 

"Basemodels will not outhandle an SH, you have to spend a at least a G or two just to get to the level of an Sh"

doesnt atts not work after a certain speed?

base models will win the 1/4 as well. I do love sh, just saying there not everything some people say they are.

 

you must be a complete idiot to say SH's came with leather when all SH's did not. If it was an option or something that's fine, some SH's have leather, but someone listed leather seats as a defining characteristic of an SH.

Which, of course, is not true.

about $1000 is right, if you get a quaife and do your own install, but once you've got an LSD equipped base, you've already eclipsed the SH's handling. the marginal suspension improvements on the SH are nice, but chances are you're going to replace most of them with aftermarket parts (coils, sways, etc). i think you can find a honda OEM LSD for less if you're lucky, because they're kinda rare, but i haven't heard glowing opinions about the JDM LSD...

i'm not trying to **** on SH's, i like SH's, but at this point the digital hasn't eclipsed the analog (ATTS vs LSD)

 

not all SH's have leather. i dont.

you do however have

ATTS
spoiler with LED
Door Lights
no rear deck brake light
always a 5 speed
and a few other things i cant think of right now.

 

I dont think all of them do, I was just stating I know they do becaues I just saw three that did.

 

I have actually seen a few with leather.... so I dunno, they were not in canada, I saw maybe 1 out of 5 so far. But why are they so few Preludes for sale out there? There is NO DEALERSHIPS in my area that has them? I did the search and I still can't find what atts is?? From what I read it has something to do with the transmision??? The only thing I found using search was people talking about removing it.
Anyways, I found a little dealership place who carry pretty much any car and they go at auctions and such so I asked them to fish out a Pear White 5spd prelude for me, and they said they'd keep me posted... I'll probably be ready to buy in a month or two. I am starting a new job so I want to get "settled" in first.

How ATTS works, as I understand it
Now, I have to say first off, that I have not had the opportunity to tear apart an SH tranny, so I might be off on my explanation, but if anyone in the Texas area has an SH, and doesn't mind me popping the axles out of the tranny to take pictures, I would be happy to change your ATTS and tranny fluid for you!

Okay, first off, as most of you know, the SH uses a unit called ATTS to actively transfer torque from one wheel to the other. Of course, torque is transferred to the outside tire during cornering. When the steering wheel is pointed straight ahead, ATTS does not function (the computer knows because there is a steering angle sensor).

If you have read your Helms, you will see that the ATTS unit sits to the left (as you are sitting in the car) side of the transmission. It transfers torque by the operation of two clutches. These clutches engage the planetary gear assembly, or the left central gear (depending on which direction you turn). I will try to explain as best I can, how these things work, but there's no way to understand without the Helm's in front of you.

There are three central gears that engage with three planetary pinion gears. There is a left, center, and right gear for each assembly. The three planetary pinion gear assembly rotates around the center gear assembly. From what I understand, the center central gear is fixed to the center shaft, and the right cental gear is fixed to the right central joint. The left central gear is free floating, and can rotate about the center shaft until it is engaged by the clutch.

Now, the clutches engage different parts. The right clutch engages the 3-series planetary gear assembly, and the left clutch engages the left central gear.

Straight: Both left and right clutches are off, and the 3-series planetary gear assembly, left central gear, center central gear, and right central gear all rotate as an assembly, so there is no difference in the acceleration between the left and right wheels (i.e. no torque is being transferred).

Turning Right: The right clutch turns on and engages (fixes) the 3-series planetary gear assembly. This causes the center central gear to turn roughly 15% faster than the right central gear.

Turning left: The left clucth fixes the left central gear. Now the planetary pinion gear rotates around the central gears while it rotates about its own axis. Now the right central gear turns rougly 15% faster than the center central gear. Or said differently, the center central gear turns roughly 15% slower than the right central gear.

It seems to me that the center central gear is fixed to the center shaft, and the right central gear is fixed to the right central joint.

If you look at the diagrams of the ATTS unit, you will notice that the left side actually has two output shafts; the center shaft and the right central joint. The left side has just the center shaft output that couples directly with the drive shaft. The right side couples with the differential in the transmission.

Now the hard part is to figure out how the differential works. It's obviously not a run of the mill differential, as the left side of the differential must have two outputs to couple with the two shafts on the ATTS unit. I would think that one of the shafts would be fixed to the output of the engine (i.e. it's a direct connection with the final drive gear), and the other would be the output that can vary (i.e. like a regular differential).

I believe that the right central joint (the outer of the two shafts) is directly coupled to the final drive, and the center shaft is the coupled to the "regular" output of the differential.

The question really is whether or not this differential is a limited slip differential. It's entirely possible that it is, but not very probable, IMO. I don't see why Honda would go through this much trouble, not to mention that the ATTS system might interfer with any type of LSD action (therefore actually increasing torque steer).

One way to answer the question would be to disable ATTS and see if there is any LSD action. I suppose the easiest way to do it, might be to pull the ATTS fuse (which should disengage both clutches), and put one tire on slippery surface, while one is on a surface with good traction. An open diff should spin the tire on the slippery surface without a problem. A LSD should transfer some of the torque to the wheel with traction (also causing torque steer).

 

No leather for USDM SH. you can get it from the dealer though as an add on which is probably the case.

 

there are no option for leather on the USDM SH. as stated, they were add on. they do not come from the factory with leather. someone call the dealer and talk to someone who knows their ****.

as for ATTS, it's been covered many times. just type "ATTS" using the search function.
