1990 Mazda Rx-7 - Ls1 Conversion - 6 Speed - 49k Miles - Convertible on 2040-cars

Just purchased this vehicle a few weeks back from a private seller in Maryland. I've been trying to get the vehicle registered in California, however due to the LS1 Conversion and California's emission laws I've run into some obstacles. Unfortunately I don't have the time or patience to deal with the headache. The previous owner had no problem registering the car in Maryland so I am optimistic it can be registered in another state, or perhaps here in California if your willing to jump through hoops. Due to my limited knowledge on the subject, the vehicle is being sold as-is with no guarantees regarding emission or registration compliance.

With that aside let me tell you more about this Uniquely Astounding RX-7.

This is a 1990 RX7 Roadster which has been professionally transplanted with an LS1 engine and T56 Six Speed manual transmission. The transplant was done in January 2009 by KDR Performance in New Tripoli, PA. The shop was later renamed ‘Speed One’. The chassis currently has 49,980 original miles on it while the Engine and Transmission have just under 40,000 miles. The engine, transmission and ECU are from a 2004 Pontiac GTO / 5.7L. As you will see from the photos no expense was spared on this conversion. Receipts have been passed down from the previous owner and will be included with the sale.

All factory gauges including the tachometer, speedometer and odometer have been integrated as part of the conversion and fully calibrated. The air conditioner and heater work flawlessly. The soft-top is in excellent condition and features a true rear-glass panel with defroster. All windows on the vehicle have been professionally tinted and show no signs of fading or fogging. The stereo has been upgraded with a Single-Din Pioneer CD Player along with upgraded speakers throughout. The stereo system runs off an auxiliary amplifier which is concealed under the rear cargo divider along with a red-top OPTIMA Battery. The factory head-rest speakers have also been integrated into the stereo system. Please note that the headrest volume controller built into the center console has been disconnected as everything is controlled from the head-unit. The power widows, stereo antenna and side mirrors all work flawlessly. The interior of the vehicle is in impeccable shape with only minor signs of wear on the driver’s seat. The carpets are in great shape and show little signs of wear.

The exterior of the vehicle is in excellent condition. The paint shines bright and shows no signs of swirl marks or fading. From my understanding the paint is all original with the exception of the trunk-lid which was repainted by the previous owner when it was de-badged. The vehicle has 17” Polished BBS wheels which have ZERO curb-rash. The tires are Bridgestone Potenzas and are practically new. The Brake Rotors and Pads have been upgraded to Brembo’s however the calipers are original.

Under the hood it has the LS1 Engine equipped with Hinson HSC headers, HSC Cold air intake and Fuel regulator. The exhaust system has been completely upgraded with 3” stainless steel pipes, Magnaflow catalytic converter and Dual Racing Beat exhaust Mufflers with Stainless Steel tips. Not sure if it was ever put on the dyno, but the previous owner estimates around 375rwhp.

The car is equipped with a Viper ESP-800 alarm system. When activated the alarm will lock the doors and roll up the driver and passenger window. The car is turn-key and ready for a new home. I will be including two sets of keys, two alarm remotes, factory manual, car cover and battery tender. The only think not working is the cruise control.

Please note that the vehicle is being sold as-is with no warranties expressed or implied. I am still planning to drive the vehicle on occassion so the actual mileage will be slightly higher than noted in the auction description. I will do my best to answer questions and will reach out to the past owner if I don’t have the answers. If you wish to have the vehicle inspected I will gladly assist in bringing the vehicle to a mechanic within a 15-mile radius from San Diego CA 92110.

Good luck bidding!
