Insite suggested the same, looks like they are expensive new, ill just keep looking for one in the meantime. Hopefully one pops up for sale around spring. This, is a way better solution.

You do not need the vin from the car that the motor was removed from. It has nothing to do with the ecu that the car already came with. I may be wrong about all this but I have an egas motor in my car and all i did was swap the throttle body. Same motor otherwise. Contact Pedro for real technical questions. I can help with the swap otherwise if you have other questions.

I spoke to Pedro, he was very helpful, but he was the one who told me all of the above (with the exception of the manifold) Ive already drilled one side for the 2.7 manifold, and one side to go for now.

Negative on both Jaay. The mechanical throttle mounting points are not symmetrical like the egas. Also, I tried using the center section as well. Its identical, however the 2.7 is about 15mm smaller in diameter than the 3.4. Ive thought about bolting in the center section from an egas 996, which brings me back to problem #1.

I went to school to become a mechanical engineer, and there is no doubt in my mind this would help lower the cg, but I believe this is a solution with far more negative side effects than positive.
Its not only lowering the engine that bothers me, its the shear force being applied to the mounting bolts at the front engine mounts as well. Of course, during acceleration its not an issue, as the engine will be applying clockwise force on the four bolts, effectively pulling 2 straight down, and pushing the other 2 straight up.
However, during braking and cornering has a tendency to push forward, or to the sides as well. At the very least, you guys should have 1.5"
metal spacer plate made, and not trust those poor bolts and thicker hardware store washers to do all the work.
Guys, so here is what I have been up to after work. Please keep in mind that between 8am and 6:30pm, I am working on clients cars. This is strictly after work, so progress is slower than what I would like it to be...
By the way, I removed both cylinder heads from the 3.4 for the following reasons
#1. I never just install and engine and throw it in the car (clients or my own) You can never trust the previous owners claims of maintenance or mileage.
#2. Drilling the heads is much safer, and there is no worry of metal shavings going into the engine
#3. I wanted to do a mild port and polish job (more like a clean up with a mirror finish on the intake ports)
#4. Im going to change the valve seals, check the valve guides, and lap the valves. Also, new chain tensioners and chain rails are going in.
And believe me guys, the engine is filthy now, but it will be looking brand new before it goes in the car.
