Howdy guys

I might have an opprotunity to get a Red 98 SH, but ive heard that the ATTS unit complicates modding certain parts of the car. But what i dont know are the specifics. Such as clutch/flywheel, exhaust, engine mods, stuff like that. Any and all help on this is greatly appreciated. Thanks in advance.

 

Type SH disadvantages:

weighs about 50 lbs more than base
aftermarket front suspension is difficult to find
ECU can't be reprogrammed (as far as I know)
ATTS unit won't handle high horsepower levels

But I'm still glad I got one instead of a SportShift

 

Obd2 is also a complication.

 

the biggest problem is that its not a 4th gen...jk

So, if thats a problem, is there a way to disable the atts unit? Will i/h/e/p/cams be pushin it for the atts? If not, what wheel horsepower will the unit be able to handle? Thanks in advance again guys!

 

I've read the ATTS starts to fail at around 325-350 horsepower so you should be fine unless you plan on running high boost or nitrous and boost. I assume you could disable the ATTS unit but you would still be stuck with the weight.

 

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 ****, 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 . . . .

more like 240whp or over 7psi.
