The 2.8 Saab engine came with manual transmission also.
However, that's a Bosch rather than Delphi ECM and will be different to adapt than the Camaro unit.

It gets more complicated as more donor vehicle parts are mixed and matched. Then add on top of that aftermarket or custom parts AND a custom tune. It could be a lot of work getting all the bugs worked out. I am not against mixing and matching, I just think that my skills limit me to keep as many factory assemblies as possible. For example, I want a High Feature V6 with a manual transmission, that means I look for a HF V6 that came from the factory with a manual. That just seems the easiest way to do it, and fewer issues. BUT, I want to convert my automatic transmission to a manual in my Fiero that already has an LS4 that never had a manual option, so I am forced to mix and match to get what I want.
In the end it depends on how much time, money and effort you want to spend but more importantly is the goal you want to achieve. Knowing exactly what you want is just as important because that will guide your research.[This message has been edited by Rickady88GT (edited 01-08-2019).]

Rickady88GT, not as bad as you are making it out to be. 2012 Camaro had an LFX with a manual transmission. The clutch is a bolt in from the Saab 9-3 Aero. I am almost done with the wiring changes and have had few problems. Guess I won't know for certain until I get to the point where the key is turned, but I am an optimist.

Cool. I look forward to seeing video and pictures.

The 2.8 *IS* a high feature V6.
I've been musing for years that it would be fun to bolt the Saab turbo system up to an LLT... although with a bigger turbo, of course.

If you want to go turbo, do twin turbos from another high feature. Also, the Saab high feature was port injected. The LLT and later are direct injected. [This message has been edited by Daryl M (edited 01-09-2019).]

The later twin turbo V6's use integrated exhaust manifolds and the turbos bolt directly to the cylinder heads. Just use the whole pullout engine in that case.
The Saab manifolds should bolt right up to the LLT and the crossover pipe will most likely work too... just needs a bigger turbo. Although I don't know where the HPFP is on an LLT right off and how it would relate to the crossover pipe.[This message has been edited by Will (edited 01-09-2019).]

Do twins Will, that's what I'm planning for the CTS. I'm collecting hardware for the build now and sizing things up with the intent to mount the the turbos up high for gravity oil return instead of the scavenge pump most of the turbo Camaros are using along with low mounted turbos, as well as leaving room for catalytic converters.
The turbos are pretty compact next to one exhaust manifold, GT2860s with .86 turbines and ~330 hp rating. Not expecting to have it done by the end of the year but would at least like to have it completed on the engine stand. The aftermarket supercharged camaros are achieving 400+ hp at the wheels, the turbocharged versions are doing even more except with a lot more torque and using less boost pressure, best dyno sheet I've seen was 500 hp and 475 ft-lbs at 11 psi. I'm not aiming that high but, would like to reel in the 0-60 times from 6 sec to the 4 sec range with the 6 speed auto. It already has 11.3:1 compression so no engine modifications are necessary to increase it.

That's the drivetrain that bmwguru installed in his car. He ended up using the AEM(?) PCM. Couldn't get the stocker to do what he wanted.

Sorry in advance Steve... this just reminded me of a phrase that is a applicable to that comment. "just another Saab story"
On a more serious note, that was 6 years ago and there are now more mainstream high feature applications and with that comes more tuning support - especially from the Camaro platform.
