The TB'* aren't 58-70mm. My 93 SSEi has a 77mm bore, with an 81mm outer diameter. Jseabert'* 93 SSE is identical.
The original question asked the difference between a 92 and 94 SSEi. The exhausts between all SSEi/SSE from 92-94 (and the 95 SSEi) are all identical. All the SSEi'* had the same final drive ratio in those years, too.

1994 SLE: 3.06 ratio option FW2
1994 SSE: 3.06 ratio option FW2
1994 SSEi: 2.93 ratio option ???

That may be true. My measurements are for intake pipe fitting. I know I've seen the 92/93 TB side by side with the 94/95, (SC end) and there is very little difference. From 3-5 feet away, you can't tell which is which.

Makes me wonder what the 93 is. I don't recall it being that small. And with the valvetrain difference between 92 and 93, why did the performance numbers not change?

You might be right. Since the day I bought this car, I knew there were more than subtle differences between it and the 92. For some time, I thought it was a late-production 93, that got the 225hp motor. Don and I had several offline discussions about this a year or so ago.
I've driven stock 92 and 93 SSEi'*, and there is a perceivable difference in performance.

Was the 94 SE a Loaded with everything bonneville? Or just the bare bones Bonneville?
You could be right on the 2.97 ratio as I couldn't find that one in the RPO'*, was going off a cloudy memory from when I was considering putting a 4T60E-HD in my SLE.

I thought i might have an early 94 a few times, but I know better now.
The engine changes are just how the rockers work, they wouldn't give better flow, or longer throw with the valves.
Maybe it was for reliability in rollers over the 92 ones.
