The setup looks real nice! I need to do a front facing intake once my car's 100% again. Since you're auto how does it drive without the stock throttle body?
It hasn’t started yet needs tune which is supposed to be Tomorrow!

She is good now but the ECU needs to be wired as off now ac and Trans control aren’t working… car is running now, coils were flooded had to be cleaned one by one.

I believe you have to use the stock throttle body along with stock TPS and APPS for the trans to work. I tried wiring my standalone to do the DBW and it worked, but the trans didn't work properly. I've seen someone mount it remotely in the engine bay and the car works fine, while having a cable driven throttle for the engine.
Y85 of a 86 has been ordered for $450 and will be installed this coming week.

So the car is with me 1st and 5th gear aren’t shifting so she will go to Adam at JEMs so he can wire in the trans control into the HALTECH he’s the man for it. Stock ecu can no longer do the job too many mods.
More mods have been added and first post updated.
