Semi-mobile, it was off to PF Supercars, where Ray Wilson met the task of getting the rotary running. Needing a rebuild, the 13b motor was pulled apart and the seals were replaced with fresh stock units and the housings ported to a mild street spec before being reassembled. A GT35R turbo kit from A-Spec Tuning, complete with A-Spec Tuning manifold and downpipe, TiAL 44mm wastegate, hkS Super-Sequential blow-off valve and Rotary Extreme v-mount intercooler replaced the overly complicated oE sequential setup. bye-bye rat's nest. with the motor and turbo system in place, wilson focused on the details; installing items like a freer-flowing GReddy throttle-body elbow, k&N filter, kakimoto Racing midpipe and Racing beat dual-tip exhaust, and spark-amplifying hkS Twin Power ignition, Magnecor spark plug wires, odyssey PC680 battery and NGk Iridium plugs. Fuel delivery was increased with kGParts Fuel System injectors (1,600/550cc), a secondary fuel rail, stainless lines, an Aeromotive fuel pressure regulator and two fuel pumps off a Toyota Supra. with the rotary firing, Wilson dropped in an Exedy clutch and tuned the buffed 13b with an APEx'i PowerFC squeezing 423 hp and 309 lb-ft of torque out of the tiny 1.3L; good for a 11.9 second run at 119 mph on the quarter-mile. Not too shabby for an old girl, eh?

"In the past I've built many hardcore vehicles for mountain/track driving. with the Fd, wanted to showcase something beautiful and unique while retaining comfort and daily drive-ability with such amenities like A/C, heat and comfy seats." Reliable and more importantly, actually driven on the streets, Terry's rotary is a purring MILF, one we'd take home over a haggard pop princess any day. Gimme more, in this case means one with more age.
