There is one main coupler inside the transmission that connects the clutch input shaft to the input gear shaft that needs replaced to really strengthen it, but otherwise it shouldn't be an issue.
he's using the original transmission and at dyno, he put down 400hp at the wheels using a 2JZ.
This is the shaft in question that will be made bigger on one end (one end has the coupler on it), and longer.

First, congrats...this will be a great build. Just read all 4 pages. Keep her under 88 MPH so we don't loose it to some other time, lol. Sorry, couldn't resist.
Be careful when comparing 400, 2JZ HP w/ LS1 torque. The 2JZ makes HP through higher engine speed where as the LS1 does it w/ torque. So, the torque that the transmission sees is higher in the LS1 @ any same (given) HP.
Make sure to calculate the section modulus & know the material used, just to be sure. Aftetr that, look @ the gears & for absolutely add a strengthening plate to keep the transmission housing from flexing. This is a real transmission killer & is why 944 Kits add the plate to the turbo transmissions used when moding for LS1 torque. Ref., Texas performance. Go there to see what I'm describing.
Don't want to see the finals project (thesus) fail 'cuz, the tranny ends up in pieces.
Subscribed & will be following w/ great interest. Thanks for posting.

Its already pretty light (700+ lbs less than an average 4th gen f-body).
That weight distribution is the concerning part though. What is the weight difference between the stock PRV engine in the Delorean and the LS1 + bracing being added?
From some digging it seems that the PRV weighs 331 lbs and the LS1 weights 390 lbs. So that's an increase of 59 lbs in the rear, which isn't that bad. You might want to weigh the two engines to get more accurate numbers. Don't forget to account for the weight of any adapters and bracing that needs to be added to mount the engine.
Some people have done some work to remove weight from the rear and add some to the front to even out the f/r distribution.
Check out the forums over at DMC Talk & DMC Help too.
Please keep this thread going. Good luck with the project.
