Busy Busy here👍 , AJ brought his car in couple weeks ago to get some work done. Over the last 5 years we built a motor for the car and a transmission, along with fuel system and more. These cars don’t fair well generally in storage for long time . They definitely tend to wake back up from the slumber with a thing or two to address.
We decided to replace the 40 year old ac system with everything in the engine compartment. Then going in after and replacing the evaporator and heater core & heater valve too. Cleaned everything up and turned out great . Shop was 97 and at idle was in the 58* range .
Also did a new ignition on the car. Coil had corrosion on the coil towers.
Headliner was sagging bad . Got a new one installed / map light. Came out in pieces.
Trans service / inspection and small leak at pan
Car has an aftermarket antenna on the car that didn’t work so we found a nos . To start over and installed. Antenna works great now.
Oil leak by drivers valve cover . Drilled out breather. For more flow etc foam removal
Great car , now off for some paint work .

Jon from east Texas brought his 87 GN to me to start work to rebuild his car mechanically .
Theme fast street car: 500-700rwhp
The start of the project. The engine will be built soon so the surrounding components should match.
He opted to -

Full fuel system :

Jose’s under chassis work
Turning Jose’s car around in a big way!
08/10/2026
Alright, things are rolling at the shop again after vacation. Jose had brought his car in at the beginning of the year for a 5 hour check out . Car didn’t want to run. After check out , I discovered a bent valve . So I got that fixed and Jose decided to do some solid work on the car. It had an old grey box fast ecu from 25 years ago and he wanted something up to date and keep a stock type theme for the car.
Great results!!
