Just got finished pulling the engine and trans out of the SA <1 1/2 hours. I need to do a little cleaning, sandblasting after I get the V6 squared away.

Just though I'd raise some blood pressures.

V6?

Why not another V8? Other than a GN V6, or an SHO V6.

*under my breath* economy, LOL. They get 30+ MPG in a 3300lbs+ camaro, buick, etc... so I'm hoping for a little better. I want this one to be a DD.

That GM 3800 motor is a good little unit. I used to get up to 30 mpg in my 90 toronado Trofreo, not a light car and pretty much maintenance free. The rotary is still more fun though.

more power and ALLOT more cost. My complete drivetrain cost about 10% of a complete LS-1 package.

The GN engine is good, but lets not forget the SC versions of the 3800. Not anything to write home about in stock form but let's say you can get the same power as a GN.

Keep in mind that this is just the start.

Only V6 I would swap out is the one you find in an NSX Would be hella expensive, but damn cool

Then again, I have no plans of doing a swap anytime soon

Yay for the V-6!
I love rotaries,but I have a soft spot for V-6's.They are so unloved,but they are just about the most utilized engine design over the last 20 years.Compact,powerful and theres a million ways to make one with regard to drivetrain and valvetrain.Probably the only downside of a V-6 is the warbley exhaust note.Headers help,but its still a little funky,not like a smooth straight six.

My fav. aspect is the size.They fit in anything as I proved with my 87 2.8L TBI Chevy S10 engine.Originally in my high school GLC,I recently moved it into my new 87 Samurai.Probably one of the most cramped engine bays out there,I still had room for headers and a PS pump.And I can still change the plugs and get my hands down to the frame rails.....

Nope.
Extra throttle control cable runs to a fingertip throttle mounted on the shifter.Theres also a starter button on the shifter(T-handle Hurst).
Both are common rock crawling mods designed for throttle and re-start ability,without having to move your hands/feet from the other controls.

So what are your plans for getting the engine RPM down so you actually see the economy of the Camaro/Firebird? Steepest gears those cars came with were 3.42 and had taller tires.

I've seen VG30DE's in 1st gens but not TwinTurbo versions, I don't think there is enough room. 302 swaps are the easiest out of all the swaps. Grannys bolt-in kit works exactly as they say. I'm about to go out and rip the 12a out of mine to start my under $1000 5.0efi swap.
