any help would be appreciated. what would be needed besides the base tranny? i'm assuming base axles, intermediate shaft,ecu?

any input?

will there be any ecu issues if this was done in a 2001 model?

 

take out atts.. put on 3rd brake light... base model rimS? why would u want to turn an SH to base?

 

i know wtf? atts kicks *** doesn't it? **** i want a SH instead of my base -_-)b but i heard the SH weighs a bit more... but **** and the SH rims look better thats why i got em on my base

 

Other than a boatload of parts (=money too) there is a lot of time you will invest. The suspensions up front are not the same and you will need to redo other things as well. It is not worth the price and you could easily devalue the car as the Serial Number does tell what the car came with originally.
My advice is to consider doing nothing or finding a Base to trade for. The ATTS is a very technical component and works when it needs too. Personally, I'd trade and put a Quaife in the car, but that is my view.

You'd need to get base cams too. AND ARE YOU STUPID?

 

i didn't buy an SH b/c i knew i could accomplish the same thing with a quiafe and save weight

 

I have a 99 SH and wish I had gotten a base. The ATTS is heavy and can't handle high horsepower. Bad for drag racing. So wanting a base over an SH isn't necessarily stupid.

i dont think his idea is to make it just like the base/ i think he just wants to get rid of atts, due to higher hp levels.

ive heard rumors of the sh and base block being different, but i dont beleave it.

 

RAB, yes I'm stupid. Thanks for your overwhelmingly helpful post.

Now back to the point. I realize it would cost money to purchase all these parts and etc. I realize the ecu would need to be changed, the hub sizes may be different but I know the dimensions of the care are identical. Meaning, the geometry and location of the base/sh motor and tranny.

I'd really appreciate any information that can be given.

I'm in the market and looking at an sh shell currently. Now since all of you are curious as to why Iwould want to do this, this is why. Please keep the opinions to yourselves and just take a minute every once and a while and truly wonder why someone might pose a question like this.

Thanks.

 

just to clarify, i'm more interested in what it takes to convert the car to base tranny specs. concerned with the atts ecu and it's location, immobilizer issues, hub and axle spline count, intermediate shaft, etc., etc.

thanks.

 

why in the hell would you change a sh to a base you might lose a hole 200 lbs but so what..why dont you just sell your car and buy a base?

 

The difference in weight is only 88lbs, and alot of that is not even ATTS but other suspension bits, sensors, etc. The blocks are also different, on the SH the oil filter is accessed from the top (PITA ) and not from the bottom like on a base. The header is also different.

Yes the blocks are different, but only slightly and only because ATTS would get in the way of the oil filter on the base block.

Anyhow, I have heard of a few others trying to do this (swap out the SH tranny for a base) and I think at least one person has accomplished this. Unfortunatly it was several years ago when I heard about this and I can't remember who it was.

I have an h23 tranny in my '01 SH...I posted about this on preludeonline awhile back. You need a "normal" transmission and intermediate shaft and then you can fab up an adapter plate out of 1/4" plate. Easier than I thought it was going to be...you can find pics here: http://ian.clendaniel.net/gallery/noatts

How does the car drive with the taller gearing? Just curious, but are you FI?

Gearing's not too much different, the FD and 1st are the same with a little more spacing between the rest ending with a taller 5th...I actually like it a little better than the stock tranny, I always got caught reaching for a 6th on the freeway even while NA. As to being FI...yes, it is.
