An HKS single would demolish a T2 Rotary with 89,000 miles. Buying anything rotary powered for cheap is usually pretty risky. in terms of power I have a friend that has an FC with a T62 Turbo (among other things) thats putting 325 to the wheels. but from what ive heard has still been owned by SR20s with Bolt ons (Intake/Exhaust/DP/IC)
2.0L inline making 202HP > 2.6L Rotary making 205HP
Im all about HP/Liter... do whatever you want but i cast my vote for the 240 with SR or CA
