Default swapping 5.3 chevy into colorado questions

Is it fairly plug and play to put a 5.3 into a 2005 colorado? I know at some point the 5.3 was an option, just wondering how big of a wiring hassle it would be to put the 5.3 into a i-5 truck?

if you were able to find a 2009 or newer donor for the parts it would be plug and play.

I knew they put the 5.3 in, didn't know what electrical differences between the two, or what needs to be pulled from the donor vehicle.

I'm not 100% on this, but you may also need a front diff as the I-5 mounts it with and thru the oil pan. I had a 5.3 Colorado in for a little lift and the diff in those mount similar to the 1/2 tons and others, nowhere near the pan.

The truck had power. I liked it.

Other than this, I have no advice.

Good luck with yours.

This would foil any ideas of cheaply putting together a colorado with a 5.3, I imagine the front diff isn't free.

Not to mention any frame mods needed for it. Could always straight axle it.

The thing will be a money pit in no time.

Yeah it sounds that way.

My f350 is way more truck than I need, or really even want. Looking for a slightly better fuel mileage, smaller 4 person camping, biking, snowboarding, fishing, log hauling vehicle.

Frame mods and different front diffs and otherwise starts to sound expensive. Maybe I'll look into if I can find an i-5 cheap

I bet you can. Otherwise I like the turbo 5.3 swap.

Let me know if you pass on it.

Curb weight of 4070 vs 6300lbs and a smaller front cross section with the same 5.3L................I like where your head is at. I'm able to pull 18mpg highway with a 1/2 ton crew cab consistently, you should be able to get low to mid 20's out of the Colorado I would think.

I just dont understand, I remember reading that your wife didnt want an extended cab half ton because there was not enough room in the back? The half ton would have much more room than the crew cab Colorado's. Them bitches are small.

I do understand the marginally better gas mileage, but I hear the I-5 is under powered and not that much of a gas sipper.

Sometimes the wife doesn't always get what she wants

I have seen a few colorado's with blown motors, crew cab 4x4's, for around 5k or less. Add a $1500 5.3 and some elbow grease and you have a 20+ mpg crew cab truck to take the family camping, snowboarding, bike riding, etc. Sure you're giving up some space, but considering I don't do much towing it works.

The i-5 h3 I had pulled down a consistent 19.5 mpg (mine was a stick)

A half ton crew cab with the 5.3 is still a 12-15k truck.

I'm not worried about the mileage savings, more with initial purchase price at this point, trying to consolidate and cut some costs.
