The f22 tranny and H22 are all the same, and will bolt up. the only difference is the gearing inside. If you decided to do a complete swap though, you don't need to worry about this.

The F22 transmission is the same transmission with different gearing. I dont believe that the relability is different between the transmission. But the gears are very very long which makes your 1/8 slower, at least with NA.

One guy did a swap from F22trans to the SI trans, his 1/8 time was 1 second faster, thats a big difference.
