Hey guys, so I know only a single nova that went with a 4.2 Vortec I6 and then turbo . I want to do this in my daily as I find complete swaps (all wiring, accessories, tranny, ecm etc) for about $1500.
With 275hp/275ftlbs and still the good gas mileage it seems like the ideal swap. heck with a few bolt ons and a cam I dont see why they wouldnt break 300whp 300ftlbs easy. I plan on boosting mine.
ive been doin more and more research and yes I have seen that it is indeed a bit tall. One other thing is that its a front sump setup. : /
On the other hand, the colorado I5 is rear sump.
I found this on another site
07-08 3.7 I5 242hp/242ftlbs . Makes me wonder what letting it breath better and a cam would do to it. Anyways, here are some pics for comparison. Im off to learn more about this I5...
4.2 I6
3.7 I5
more specs on I6
From the front of the water pump pulley to the front of the bell housing 32 inches
Widest part of the engine with the power steering pump 27 inches
Top of the front of the valve cover to the bottom of the crank pulley 24 inches
Top of the front of the valve cover to the bottom of the oil pan 30 inches.
For 2006, power was increased to 291 hp (217 kW) @ 6000 rpm and torque to 277 ft·lbf (376 N·m) @ 4800 rpm with the addition of a MAF and a complete internal redesign of the engine. The Atlas LL8 was on the Ward's 10 Best Engines list for 2002 through 2005. Engine redline is 6300 rpm.
makes me wanna go with the I6 . I mean, pretty much 300hp from a 4.3 litter I6!!!! Technology is crazy nowdays.
Since the colorado I5 has a nice 5 spd available I may go for that and turbo. Would be nicer mpg

so looks like the I5 would be an easier candidate for this. Plus theres a 5 spd readily available for it.
