Intake Manifold
I was thinking, and theoretically, could it be possible to put the aces Mid-Rise, Single Plane, Carb Style, Cast, 4150 Style LS Intake Manifold on an '09 lacrosse super, and then throw on an aces kill shot fusion lite, and then use a T42 TCM for my tcm? -

The Super would have the Northstar V8 and while the engine was mostly sorted out by then they are higher maintenance and are a Premium Fuel recommended car, so you have to be willing to be spending $5+ per gallon. The 3900 V6 isn’t as exciting but it’s dependable and reasonably fuel efficient for such a large car- 1

Took a look at the details in the recommended setup from PSE (Puget Sound Energy) and they say the typical house uses 20 to 40 kW over night and then having a battery pack equal too plus 10% for EV charging.

Roadster 2.0 with huge deposits and still no car. Tesla promised a Roadster with 0 - 60mph in 2.4 seconds. BYD, sexy as hell as they deliver this roadster sexy monster! 0-60mph under 2 seconds.

What would you do?
The 2009 Buick Lucerne is an absolute SLEEPER car, but $18,000 is a bit much. A better price for one of those bad boys is about $3,500-$9,000. The super is also a MUCH better package as it has everything a cxl has, but with a 290 hp v8 -

It sounds like it all depends how big the storage is and how much you need to charge. It is possible you wouldn't have to pull from the grid though.- 1

Starter Car?
I'm 14 and looking for a good year round car to drive that still has potential to go sideways when I floor it. I'm thinking something like a 2009 Buick lucerne super that I can turn into my own little project car. Does that sound like a good starter car? If not, any suggestions? -

I guess I'm going to have to look into this. I do know my city gets its power from somewhere (likely Ameren), but it isn't an Ameren bill. It is a bill straight form the city. our Ameren bill is just for gas.
