Nissan VQ35DE 3.5 L V6 engine 250 to 270hp

My understanding is that this engine is a FWD transverse style platform.

What are the Pro's and Cons of using it in an exoskeleton car? I believe that Fran Hall with RCR said that the engine would probalby fit an SL-R.

My questions:
Does anyone know the reputation for reliability on these motors?
What are the six speed manual transmissions like? Smooth high rpm shifters?
Most important, what tuning software and companies are available?
Can the ECU be flashed and modified easily to accomodate aftermarket modifications?
If you get an automatic engine, will it bolt directly to a manual transmission with the appropriate flywheel selected etc.? Is there any difference between teh automatic and manual engine?

Ultimately, why or why not.. would the be a candidate for an exoskeleton car?

Discussion and comments welcome.

Quote from wikipedia:

"This engine is widely considered to be the world's benchmark V6 engine for its combination of smoothness, reliability and high power output. It was on the Ward's 10 Best Engines list for 2002 through 2006, the only engine to be on Ward's list every year since it's inception."

Other quotes:
"Just found out about the weight of this engine. Just so you know it's only a liggle (40lbs) lighter than the 5.7L Corvette engine. Work that one out."

My thought is for the extra weight of the 6 cyl and similar hp from a other 4 cylinder motors I would stay with the 4.

not to mention it's Top-heaviness..... I'm now in the midst of designing a system for running rotary (RX8) engines on a FWD gearbox.... these engines are so small and compact that I managed to lower my drivetrain CG by about 200mm...basically smack dab right on the rear axle.

Not to mention losing almost 50Kg on overall weight...

With a v6 you are going to have almost all the weight of the engine, above the axle...

The problem I see with the VQ35DE engine is the low rev range and the high torque for such a light car. The fitment is a challenge that will make it harder to work on, and the higher CG weight is also problematic. The tunability of the Acura RSX motor seems likely and the motor is relatively inexpensive.
