#1 of 18 Will GM ever drop the I5 and go with a V6? by rocketman67 Dec 18, 2006 (10:06 am)
When it came time for me to think about replacing my '95 GMC Sonoma KC 4x4 5speed with a Canyon/Colorado I quickly changed my mind when I heard they were going to use an I5. Now I see for '07 you can't even get a manual with the I5. What is GM thinking about? I don't understand why they just didn't stick with the tried and true 4.3. They obviously still like the 4.3 because it is being offered in the '07 Silverado. Replies to this message: dmathews3 (Dec 18, 2006 1:14 pm) rocketman67 (Dec 18, 2006 1:35 pm)

Replying to: rocketman67 (Dec 18, 2006 10:06 am) There is nothing wrong with the I5 as I've had mine for over 2 years now without a problem. Runs great. As far as a manual with the I5, my guess is if they had it before than the reason they don't have it now is either the increase in displacement and power is to much for it or most likely not enough interest in it to go to the hassle of messing with it. I can remember when I worked at GM one the N cars (Grand Am type) air conditioning was an option. We ran 60 cars an hour off 2 lines on 2 shifts. Thats close to 2000 cars a day and if 10 of them came without air it was luck. After 2 years air was standard and you couldn't buy one without it. I'm thinking the same here.

I see even Volvo dropped their I5 in favor of 4 or 6. There is no mpg advantages in the I5(gas) if you compare it to a v6.
#4 of 18 I5 vs. 4300 by th3_d3v1l Dec 27, 2006 (10:27 pm)
Why would they drop it? They have made no improvements on the 4.3, I just got rid of my 05 Silverado in favor of an 06 Colorado with the I5, the I5 has noticable increases in horsepower. they could give that 4.3 more power than Toyotas 4.0, which boasts 260, and nissan which I believe is 275. If they really got to the nitty gritty with that 4.3, it could be the most powerful 6 on the road. But in all reality, I like my colorado more than my old silverado.

#5 of 18 I-5 by fordenvy Mar 05, 2007 (9:05 pm)
I-5 are more reliable because there is less wear and tear on the engine. the pistons move up and down and not on an angle, plus they are more balanced giving less vibration Replies to this message: jpf (Mar 06, 2007 7:35 am) rocketman67 (Mar 06, 2007 8:13 am)

Replying to: th3_d3v1l (Dec 27, 2006 10:27 pm) IF the I5 is better than the 4.3 then why is GM not unsing it in the '07 Full Size trucks? They are still sticking with the 4.3. Check it out if ya doubt my word. The 4.3 from GM and the 4.0 from Toyota is being outclassed by Nissans 4.0. Look at the HP and Torque specs.

Replying to: rocketman67 (Mar 06, 2007 2:41 am) A plant can only build so many engines a year and my guess is they are near max on the I5. Why would GM spend a few hundred million dollars to tool up a new plant to gain more I5's when there is nothing wrong with a 4.3?

Replying to: dmathews3 (Mar 06, 2007 3:33 am) If ya look at the torque and hp specs comparing the I5 and the 4.3 you will see that the 4.3 is a better truck engine because of more torque at a lower rpm. The 4.3 is in need of some serious make over but I don't think GM has the bucks to spend of updating the engine. Either that or they just too pig headed .......the later I'm more apt to believe.

Replying to: fordenvy (Mar 05, 2007 9:05 pm) The 4.3 is a proven design. I know of many contractors that really worked their 4.3's to the tune of 250,000 to 300,000 miles without major problems. The I5, with its valve and head problems is breaking down in less than 100,00 miles. At this point, the 4.3 is a more reliable engine. Until GM fixes the problems with the I5, I would stay clear away from this engine. Just my 2 cents. Replies to this message: rocketman67 (Mar 06, 2007 8:13 am)

Replying to: jpf (Mar 06, 2007 7:35 am) Everybody knows the I5 is a bad design even GM but they are just 'Whistling Past The Grave Yard' full of dead I5's.
