hey guess, this has been bothering me for the longest time. why hasn't GM made an ls version of the 4.3? if they did, i am pretty sure it would be about as strong as the 4.2 straight six(horsepower wise) but would be a torque monster engine. don't get me wrong, i love my 4.3 in my truck, it just seems alittle strange that GM wouldn't make an ls version. it would have been a better choice than the silly I5 in the colorado. what do yall think?

 

why ?

 

i heard the I5 in the colorado was supposed to be hella good on gas.....maybe thats why.....

 

EPA 2WD = 16/22
EPA 4WD = 15/21

Nothing great there.

 

just wonder what you quys would think if gm came out with ls version. the I5 is a nice engine(for a base model), yeah it has more hp than our 4.3s but where it falls is in the torque range. i have been in a few colorados(extended and crew cab models) with the I5 and it just seems gutless.

and for the epa gas numbers for the colorado, i get better than that on a bad day. i average 21 mpg mix driving and i will generally get 19 in the city and 23-25 on the highway(depending on the wind speed, number of time the truck downshifts, and how much faster i am going over 70mph.)

 

Since the 4.3 is a dead duck for GM, I can't imagine why they would do such a thing now. It is, after all, a V6. If GM wanted that type performance in a S10, they would have simply stuck a V8 in them.

 

Should have!

 

The colorado and canyon can be purchased with a V8 in them already

 

True, it's the 5.3L, but not the Active Fuel Management version like in the full-size trucks.

 

i just think its alittle over kill on the V8 part. the 4.8 V8 would have been a better choice. but then again, the 4.8 5.3 and 6.0 use the same block. anywayz, what i am trying to get at is that i think gm should have put a v6 in the colorado and canyon. yeah, it might as well be called an s-10, but atleast it would have power and have more of a competitive in the mid-size truck market.

so why are they killing off the 4.3?
