All is done just gotta wire the trans control into the Haltech, install the A340e and then tune.

Final look!

Love the build, but i am struggling with the need for a billet flexiplate, maybe you can explain what s so special about it?

I see the ring gear outer is welded on so not part of the billet, is it just to have the hub and plate made of one piece for extra strength? Do the OEM ones let go? :unsure:
If you go better Box and bigger converter you will need a stronger flex or OEM will snap.

2 Questions. What ECU or TCU are you shifting with? Do you have e-shift still and how did you get to work?
Haltech elite 2000 with Doomslang harness. Since I’m going with the Aristo TT A340e I’m also installing MV A340e Shifter. The A340e is Not installed yet but should be done next week. For now I’m using a Shimmed A650 without auto control thus I’m using it manually. I had to get it wired for the time being but after the new box goes in, for now MV shifter will do.
I believe he is a BALLER and has so much money that he should give me some lol. I think he is using a Haltech.
I wish man, Ive worked my ass off for this car and the built cost me an arm and leg, 12months of constant saving up not going out helped! paying for the mods as I moved along. I don’t drink or party and shit so kind of helped me save up more.

I got advised by MV automotive to ditch the A650 and go with the A340e out of a TT Supra or Aristo….

Oil cooler with Mishimoto sandwich plate installed. The stock bar has no room once you do intercooler and Trans cooler as well. TRD how ever you can install it on the left or right side behind the foggies.
