Too late at this point but I wonder if this place has any adapters for that engine..

https://www.rx8gearboxadapters.com/

Adapters don't really help in this case.  The transmission is part of the problem.

 

One of the reason to use this engine is because it bolts right to the camaro t5 and has a .72 5th gear.  That means I can turn just over 3k rpm at 80mph.  The stock gearbox would be over 4k at 80mph.

exhaust hackery to see if I can make stock manifolds kinda fit....

not sure how these pics are gonna show up...  one of them shows the manifold in the car.  Not sure I like it well enough to keep.

Gah....  post deleted...

 

I've decided that home made headers are the way to go...  Should be much better in the long run.

 

I took a chance on an ND miata steering joint for the rx8.  I moved the rack and the column was no longer long enough.  This makes the column about 3 inches longer AND gives it about 2 inches of adjustability. 

You can see the difference between rx8 and ND miata in the pic.

This still exists...

 

I got the engine and Trans mated for hopefully the last time.

I also got the subframe clearanced for the steering knuckle.

I got the oil cooler lines removed and made a lot of space to get the engine in and out.  Good stuff. 

 

I also got the exhaust manifold flanges installed and the motor mount plates all figured out with CAD.

I'd like to have the drivetrain mounted and be able to order a drives haft around Thanksgiving.  I still need to work on the racecar for barber in December.

Offset about 1.5 inches towards passenger side.  Helps exhaust routing and shifter positioning.

Looks great! I've always thought the 3900's intake looked so cool. It's even better pointing the correct direction.

It is rather phallic.....   still, reminds me of the grand national symbol. 

 

Let's see how long 240 hp keeps me engaged.   Maybe I paint one side like the GN symbol when I add a rotary muffler to it!

I feel like this has been a good week of progress.   I know what I'm doing for engine mounts.   I have the material.   Just need time to do it instead of drinking celebration beers and watching Australian supercars....

So engine is in and sitting on its mounts.  Pics tomorrow.

 

The Trans is connected to the stock, but heavily modified power plant frame.  

 

I'm not sure I am in love with it.  I might add a Trans crossmember as well and tie it to the ppf.  We shall see...

I am gonna have tight clearance for the driveshaft....  might need further modification once a shift gets here.
