91 is an ef and si wheels are beautiful. My rims are ls mesh rims off a integra painted. I plan on a b18c1 swap later when money is right as for now it sits with a d16y7 with a vtec head lightened flywheel stage two racing clutch full 2 1/2 exhaust and a p28 computer... Anywho as of now the peak fs is 28 hrz and its doing a 140.1 at it sealed up. This is off around 700 watts so its not bad in my op digs down so low and stays flat My buddy just bought a 95 prelude. I think it has the H22a. (Jdawg22) He wants to do a lot with it, but he doesn't have the money right now. He needs a lot of body work done to it, well not a lot more cosmetic than anything, and paint. He just bought some 18" motegi's that look real nice on it. About 2 years ago I almost bought a 89 supra. I wanted it real bad, and had the money for it ($1200), but I was afraid of the turbo going out and other little shit.
