The Type SH(Super Handling) has ATTS (Active Torque transfer system) or something like that...
It sends torque to slipping wheels; to the outer portion of the wheel that is - in a nutshell, it's extremelly fun in the twisties compared to a base 5th gen.

Also Type Sh is the top of the line...you'll get the SH spoiler and other goodies not found in the base.

You may notice SH has been applied to other Honda vehicles such as the Acura RL, MDX and RDX.

The ATTS is in esssence an LSD. Though rather than being torque sensitive, it reads what you're doing with the steering wheel and loud peddle, then guesses as to where it should send the torque.

Having not driven one, I can't really say accuratly, but most people I've spoken to say that if you're only driving your car on the street, then ATTS is a good thing, but if you plan on tracking your car then get a proper LSD.

Yeaaah buy why?
I'd rather just change to an LSD equiped tranny.
ATTS when it malfunctions, you're in your own world...much like when the ALB system fails on 3rd gens :sick:


Here's just how the two cars came out in the US:





and the base...


The main exterior difference(because you can get the spoiler and skirts as options) are the wheels.


...i think SH's have slightly different interior some help me out...

That would be a waste of money although it is possible and I think has been done. The SH also comes with way sexier wheels. But other than that they are about the same.

The word on the street is that an SH is harder to do engine and suspension mods to because of the ATTS system.

Lol beat by a minute.

As for the interior... I believe you could get leather wrapped steering wheel and shift knob with the SH as well as leather seats only came in the SH or SE up here in canuck land. As for an SH with clothe seats the pattern might be different cause my friend does have a SH and the pattern on the seats is different however his is a 99 and mine is a 98 so that could be it.

Oh and a SH also came with painted side skirts and rear lip. Where as on a base model they are just black.

W00t w00t this thread made me a Gold Member. Suck on that... Why am I just a gold now I have been around since Prelude-Tech days.

both the base model and the SH have about 200hp to the flywheel. Although when dyno'd and powered measured to the wheels the base model puts out a couple of more horses because the SH looses a bit more power due to the ATTS system robbing some ponies.


The SH prelude ATTS problem with high horsepower is that it shuts off in the range of 220-250 horsepower and becomes useless. The base and the SH have the same engine albeit the SH block is a little different with the oil filter being in a different location than the base prelude to accomodate ATTS.


if you want a drag car, get the base.

if you want a car for auto-xing, track, road courses...etc, get the SH.

you'll find parts easier for the base, for the SH you'll have to hunt.

if you want to go turbo with an SH, you can always disconnect the ATTS unit.

LSD not compatible with ATTS.

ATTS: Active Torque Transfer System.
It basically sends more power to the outside wheel when cornering making it spin 15% faster than the inside wheel.


both base and SH models are identical when it comes to the engines power at the flywheel. The SH has some accessories that the base model does not have such as a leather shift knob, spoiler, different rims, and some others

front suspension is different on the SH (biggest thing people dont realize). the geometry is different (specially designed to reduce torque steer) and the exhaust routing is slightly different to accomodate the ATTS.

The SH has a different block, it's a fact. That's why the SH and Base trannies is not a bolt on swap. Internally they are the same, but the block design on the outside is differnt. Intermediate shaft and tranny mounting, oil filter and a bunch of other stuff.

There is a thread on PO.com that details how to do a SH tranny swap to a base, it's not easy and involves fabrication.


The swap to a base tranny is NOT DIFFICULT. Trust me, I've done it...they are my pictures on preludeonline. The _only_ difference is the SH block has mounting points for the ATTS unit instead of an intermediate shaft. The modification to bolt an intermediate shaft up only takes a little bit of work to the bearing carrier of the shaft as well as the fabrication of an adapter plate (which is simply a drilled piece of 1/4" plate). You can retain your SH axles and nothing else changes...you only need a base tranny and intermediate shaft. My pics are here:

http://ian.clendaniel.net/gallery/noatts

Yeah, the front suspension difference shouldn't be a deterrant - it's really not a big deal. Just replace the springs & shocks together.
There is a small difference in the exhaust manifold - the SH collector ends a few inches farther downstream than the base.

The oil filter is in a different location on the block, but all that means is if you get a JRSC kit, it needs to be relocated.

All the other issues all revolve around the ATTS system. Like has been mentioned already, in high powered applications (turbo, supercharger, or extreme n/a), it will have trouble handling the power. If you just want nitrous, you might be alright since you're not spraying all the time. And you're not likely to spray around too many corners where the ATTS would actually be operating.

You also won't be able to install a limited slip differential at the same time as the ATTS - if you decide you want one, a tranny swap & mild custom fabbing will be in order. And if you decide to go to a stand-alone management system like Hondata or AEM, you'll lose the ATTS functions.

And then there's those few extra pounds up front. **shrug**

All of that said, there are definitely advantages to the SH model - little things like the courtesy lights on the doors, leather wrapped shift knob, the spoiler & brakelight-less rear deck, stuff like that is nice. And of course, within it's boundaries, the ATTS works very well at getting rid of understeer. It's extremely fun on highway on-ramps . . .

-SH does not have more power. auto preludes (5G) all have 190hp, Manuals have 195hp (1997, 1998) and 200hp (1999-2001). SH come ONLY in manual

-the difference in hp was never quite accounted for, some say the 97-98 were underrated, some say it was just ecu tuning, either way it's not a big difference

-SH and base lude differ mainly because the SH has ATTS, which essentially makes the front wheels turn like a tank when you turn hard (more torque to the outside wheel)

-other than that, the suspension differs in that the upper and lower control arm designs were changed to reduce torque steer. it is slightly stiffer too.

There are actually quite a few differences between the base and the Type SH suspension, The springs are not the same. The type SH springs are a little taller. The struts are different as well, the base where the spring is perched sits lower on the Type SH, hence the taller spring. It results in a little firmer spring rate than the base. Lets not forget to mention the front knuckles are different, the raius rods, the front trailing arms, and the roll bars are a couple of millimeters thicker than the base front and rear. In the rear the springs and struts are different on the SH, it has the same condition as the front where the perch that the spring sits on is slightly lower than the base model, and the spring is slightly taller than the base model, It is not as big of a difference between the SH and Base rears as the fronts are though, the rear trailing arms are a little thicker as well but not much. The only problems with aftermarket struts would be modifying the dust gaurds on the struts with stock springs, however if you go aftermarket springs and struts that are replaced in tandem you will not run into any issues..


Here is a brief synapse of what ATTS is and what it does. under straight line acceleration the system operates like an open diff meaning that only one wheel will spin on a slick surface (eg.. like ice), also at the track it only spin one tire just like an open diff. There for ATTS is not an lsd. ATTS is located on the left axle, it is essentailly a smaller tranmission, it hydraulically activates gears in the unit to route the power.When you are traveling at speed and you corner there are senors measuring the cornering force, speed, and throttle input and can send as much as 80% torque to the outside wheel when cornering. There is a standalone unit that controls the ATTS unit itself, it is also connected to the ECU. So if there is any imminent danger to the ATTS it will tell the ECU to cut power.

Honda redesigned its sport coupe for 1997. Again front-wheel drive with a 4-cylinder engine, Prelude rode a 1.4-inch longer wheelbase than before, and measured 3.2 inches longer overall. Curb weight rose by 145 pounds. Interior dimensions changed only slightly, but trunk space expanded by nearly one cubic foot. Basic 2-door notchback styling continued from the 1992-96 generation, but traditional analog gauges replaced vacuum-fluorescent instruments. Only base and SH editions went on sale, each equipped with a 2.2-liter 4-cylinder that employed Honda's variable-valve-timing technology. Running on premium fuel, the engine developed 195 horsepower with 5-speed manual shift, but only 190 horses when equipped with an automatic transmission. Offered only on base Preludes, the automatic transmission gained a new manual-shift feature, called Sequential SportShift. The gear selector lever could be left in Drive for regular automatic shifting, or tipped forward or backward to permit manual gear selection.The SH model went on sale first, equipped with a new Honda-developed system designed to combat the tendency of front-drive cars to plow, or understeer, when accelerating through a turn. Called the Active Torque Transfer System, it automatically distributed more of the engine's power to outside front wheels when accelerating in a turn. That forced the outside front wheel to rotate up to 15 percent faster than the inside front wheel. The system could direct up to 80 percent of engine torque to a single wheel. Dual airbags and four-wheel disc brakes were standard on both models, incorporating antilocking. Each model rode 16-inch tires.
Year-to-Year Changes

1998: New paint colors were the only change for 1998.

1999: More new colors became available, but only one interior hue: black. The Prelude's engine gained 5 horsepower, and did not require a tune-up until 100,00 miles. Remote locking now was a standard feature.

2000: Preludes entered the 2000 model year without change.

2001: Standard floormats, rear child-seat tethers, an emergency trunk release were the main changes for 2001. Prelude would not continue for 2002.



thats just some of the interestin stuff i had come upon...search around...hope that helps..
i see conflict only when discussing the motors..they differ a bit..

simple little difference sh:

Courtesy door lights
leather shift knob
same painted side skirts and rear lip
straight blade wheels that weigh roughly a pound more than the base saw blades.
rear spoiler with third break light
the infamous ATTS.
The car weighs about 100 pounds more than the base model.

And yeah... what everybody else said.

Serious? Like little lights down in the door somewhere or where are they? I know my dome light turns on when the doors are opened but I don't think that would be called a courtesy door light. I need to install these lights.
