Do you think my car will perform well?

ET for a stock '92 T-5 would be in the mid-to-high 14's.

With the heads, intake and gears you should see high 13's but yeah, get headers, ASAP.
You can launch hard with that drag suspension; slicks would help and really drop the et. I agree with a 260 HP estimate but it's et that counts and good suspension, traction and driving skill can lower that more than HP numbers might suggest.

Good luck at the track.
