Additional FeaturesHad adapter plate and coupler and mounted the warp 9 at ecosmotors in Missouri. They did a good job, but they are WAY too busy to get done in a timely fasion. The controller box was done in Utah (EVequipmentsupply.com) thank you to Spencer and Mike. Working on a budget. Batteries are Walmart brand, 125ah for $75, 18 month warranty. Thanks to my friend John Cimuca for the batteries racks.


Cleaned up the wiring alot and "everything" on the car works now, soon i will probaly install the air conditioning (getting hot this summer) and seeing about some power steering
Allstate covers my car, but as a REGULAR supra, glad I converted a GE instead of the Turbo. I really love the car and am about to get it painted soon. I want to start a business converting for people. I am almost ready to sell this one and do another... This is fun... I want to sell this for $12,000 or so
