Bit of a different post- It is built but is being "repowered" so let's do a thread...

Image
A bit about the swap and such-

The engine is a 2016 Chevrolet Camaro LTG Engine (2.0T) that is advertised at 275HP and 295 LB of TQ stock.
Transmission is from a 2015 Cadillac ATS with the 2.0 . It is the 6 speed Tremec.

Clutch- Factory Clutch- The car wont put down enough weight to resist the wheel spin.
Flywheel- Fidanza Flywheel- Would not recommend. Several defects and issues.

FAQ's I usually get:

Q.Why didn't I turbo my Miata engine?
A. I didnt believe the engine would be an affordable way to make 450HP and stay together.

Q. What is my power goal?
A. I will see once its together and I can drive it. I suspect anything over 300 will be mental!

Q. Did I look at the standard Ecotec swap?
A. Yes, but the Miata Trans was something I wanted to get away from

Q. Do I think it will fit?
A. I expect it to be taller than the Miata engine but it would fit in the Miata engine bay without any issues. The trans shifter location is within 1/4" of where the miata trans exited.

Q. Will I be swapping in a new rear end?
A. I don't think I will off the bat. My expectation is even with slicks I wont be able to keep the tires from breaking loose off the line. Besides- The rear end swap appears to be a $2k dealio in most cases. I will most likely go to a 3.63 ratio

More details to come. Blog should be kept updated on www.exportedafrican.com or on Youtube @ https://youtu.be/IajZ-zl0AzY. Feel free to ask questions

Tell me about that Transmission.

I have been told the CTS/ATS trans is the best for a small car (more evenly spaced gearing with higher speed 1st & 2nd so a better launch (they purposefully gear the Camaro down so the teenagers will feel it's more powerful than it is.

BUT in looking for one the only manual trans I can find in the Cadillacs are V8s

BTW great choice!

EDIT: With double overdrives a 5 speed would be a better choice, but I haven't found a 5 speed that shifts like the Aisin - oh wait, you said that was a Tremec! I've been looking for the Aisin off the V6 engine.

Oddly enough the trans is a Tremec 3160(I think..) which is the same transmission used in the GT350
Mustangs. So far it seems like a good compact size. I really would like a BMW ear end for the crazy ratios (2.9 etc) but we will start with the Miata unit that exists today.

My hope is highway cruising at 2500 rpm at 60 but not with a 4.10 rear

That trans looks huge! What size frame/tunnel are you using?

It is a book chassis with a custom frame for the Miata trans. It was literally built around the trans so we will see if it fits.
