GRP Engineering's A90 B58 Supra "Test Mule"

A90 R&D Car


With the FT-1 Concept car released in 2014 we told ourselves that if Toyota actually brought something to the market that looked anything like the concept we would buy it without hesitation, and low and behold 5 years later the 2019 Supra landed in our garage.  

 We have a load of plans in the future for this car including a Stroker motor, 6 Port head swap and a large frame Turbo upgrade, but for now here's where we are at.
