Did all of the JDM/UKDM Prelude Type S's have the ATTS system? I'm debating putting an H22 in my Civic, and I want to do the Type S swap, but the Atts thing would obviously not work in my civic. . .

Thanks in advance

Yes. All TypeS Preludes had ATTS.

In addition, there was a Prelude model called the "S-Spec" that had the 220hp version of the H22a and a 5spd manual with a normal LSD instead of the ATTS. This version had different wheel, no front lip spoiler, and added amenities like a stereo that had been removed from the TypeS model. There are two problems with the elusive S-Spec swap however...
1) Good luck finding one. The Prelude was an unpopular car in Japan. The S-Spec was the rarest version only produced in MY 99 and 00 I belive.
2) If you find someone who claims to be selling an "S-spec" changeover swap, How will you identify it to be sure you are not getting ripped off with a normal 200HP H22A with LSD? The S-Spec, like the TypeS, had a red valve cover, but that is simple enough to change... And the block stamping is just "H22A" like all other "regular" H22As...

He's right. If you have a reliable source of aquiring a real S-spec engine, more power to you. If I were you I'd just get a USDM engine and avoid the hassle of importing for an extra 20hp. Besides, you can always make that power up with some engine work. Good Luck.

 

im pretty sure that the S-Spec had a blue valve cover like the f20b and h23a vtec, didnt it? i may be wrong but i was pretty sure the type-s had a red one and a sir s-spec had a blue one.

 

No, they were red. I wouldn't waste my money with a type S motor, just get a regular H22A and go off on it! You can make a regular one insane for the amount of money you spend on a type-s.

Does the '01 usdm Type SH have atts by chance?

 

yes

 

NM answered my own quesion...thx.

 

Well, since this is back up from the dead, I thought I'd correct myself... I had always thought that the 220ps SiR S-Spec Prelude had a red valve cover like the Prelude TypeS has. However, I recently saw pics of a wrecked SiR S-Spec engine bay, and it turns out that the Prelude SiR S-spec valve cover is actually BLACK...
