I have a 92 prelude si. I’m tryna to currently mate my mu24 5 speed atts transmission to my 92 h23a1 dohc motor. My clutch fits right up to my spline but I still have a couple inches of room and it won’t go on, can anyone help me so I can be able to use this trans?
Right I know that, I can’t afford to buy another atts block. This is my second motor. That’s why I’m wondering how I could make it work. It’s possible.

Come on OP... "I'm Broke" is not an answer. Panic is not a solution, and if you take a moment to consider a few pertinent details, I think you will see the error in your thinking.
First, the clutch and flywheel are the same as a base H22A4 or your 4G H23A1, so if you cannot get the clutch to mate up, you are simply doing something wrong.
Second, how do you intend to bolt the ATTS drive/control system to the back of the H23A1 block ? A conventional intermediate shaft does NOT work with this transmission, so you MUST use the ATTS drive/control system.
Get past these issues... and you might be good to go.
I suggest you listen to the other posters here and find a ATTS block... or the cheaper route would be to install a base H22A4 transmission and ECU in your SH Chassis.
Thank you, I appreciate that. The splines fit together fine. I think that maybe the spline of the trans is too long going into the engine so that’s why I still have about an inch of room. If I could figure out how to just mate the trans and engine together perfectly then I could worry about after that. Here are two pictures from tonight.

if you can change the output shaft from a LS trans. Maybe that would work. Also check to make sure the pilot bearing fits correctly. Or trim off some of the tip of the output shaft

No and no. This is an ATTS transmission to an non ATTS block. It is not feasible as the block does not have the mounting points for the ATTS unit. This is a lost cause.

OK, just so you are clear about my previous post: The BASE car (Standard 5-Speed transmission) and the Type S car (ATTS 5-Speed transmission) utilize the SAME OE flywheel, clutch disc and pressure plate part numbers. This means that there is NO reason from a parts standpoint why the transmission will not bolt up to your H23A block. Again, you are doing something wrong during installation. Please check your work.

How is it that you are providing completely FALSE information on your very first post here... and typed it in bold for emphasis ???
Atts mu24 trans to 92 h23a1
