Vehicle Description

A labor of love for the past 13 years the car has been gone over and modified bolt by bolt.

The latest upgrades encompass a full engine overhaul with major parts including ported heads, Texas Speed cam and LS7 clutch kit with all new supporting components along with a full AC install (outlined in mod list below).

The initial LS engine swap was done at 52,814 chassis miles with a donor LS6 engine/T56 Tremec transmission with only 33k documented miles. As the car sits with the new upgrades it has 53,330 original chassis miles (this may go up a bit since the listing, but nothing major). The car has been professionally tuned with HP Tuners by HP Logic in West Palm Beach and professionally ‘street’ aligned by Bello Motorsports.

Driving this car is an experience with the power to weight ratio and zero ‘nanny’ devices to keep your right foot in check. This is a car you have to actually drive.

The interior is in fantastic condition for being a nearly 30 year old car but the exterior could use a refresh. The bumpers, rear deck lid, wing and hood all have fresh paint and clear. There are small dents throughout and some dents that a PDR guy should be able to pull out without issue with how thin Mazda sheetmetal is.

This car turns heads wherever it goes so be prepared to answer lots of questions when you park.
Full documentation on all work done to the car along with hundreds of build pictures available.
