The RWHP range for a stock 89-91 13B RX-7 should be around 115 - 125 peaking at about 6500-7000 RPM. After 7000 RPM, the power should fall off. Some cars just seem to be stronger than others and the automatic transmission saps some power compared to a manual.

My 89 GTUs dynoed 124.1 rwhp in bone stock form. Then I did a cone intake and got 125.1 rwhp, but with the torque curve shifted up in the RPM range. Most recenlty, I replaced the cats with a Racing Beat Downpipe and Presilencer (stock manifold and cat back), which got me to 147.3 rwhp. Torque curve is perfectly flat from 3K and up, which makes for a very lively and tractable NA.
