What do you have? The i-4, the i-5?

[dvineyard]

What kind of mods can be done to the I-5. Have done the throttle body and cold air intake. Haven't seen much else except for headers and exhaust. :roll:

[NokRado]

I have the 2006 Chevy colorado I4 with a intake. It moves me along just fine. The dealer ships are being ass's about me wanting to lower it and put a muffler on it.

Well, when you start to do mods, they're going to start to point to stuff in the warranty and how you may void sections of the warranty when you change stuff around.

What are you talking about? There are a lot of mod's for the inline 5:

- A company called "Wheel 2 Wheel Power train" is has a supercharger (not available to the public, yet. They need some test vehicles. Google the name if you want more information).
- RK Sport sells a supercharger kit (a bit steep in price, but it could be worth the shot).
- "PCM 4 Less" can make a custom tune for your pickup, or a pre-made tune for your pickup.
- If your good enough with Nitrous, you could make up a Dry system for your pickup (if you look hard enough, others have done this).


That all was just off the top of my head. I am sure if you look around, you will find a lot more than what I said.

[Steve]

I think that over the past year or so a lot of companies have started making mods for these engines.

[SSgtJinx]

Calm down now!!! Colorado's haven't been out all that long. R&D takes alittle time to come out with proven modification. I would hold off as long as you can before jumping into any kinda big modification to such a new engine.

Very good advice!

[doug]

I Called Edelbrock To Ask About A Header,intake Manifold,and Head The R&d Guy Told Me There Was Nothing In The Works For The I-5. What Is Up With That? Anybody Got A Line On This?

[Coloradical]

JTR already has a header for the I-5

[doug]

yes ,but not for the 4x4

[thehkp7m13]

A CHEVY mechanic said a vortec 5300 could fit in the bay, but GM just doesn't want to do it. Is that true?

Well, the 2008 H3 will have a 5.3 in it. I don't see why the Colorado/Canyon shouldn't.

That's going to be a lot of engine for a little truck!
I wouldn't complain though.:biggrin::biggrin:

... bumping this old thread....

[brucertl]

I'm a new member to this forum and would like to ask a question about my wife's 2004 Colorado with an inline 5 (2 wheel drive automatic, z71 with 26,000 miles). She keeps getting the check engine light. We have taken it in to the dealer and they always give us a lame excuse. At first I figured she's simply not tightening the gas cap enough but I'm beginning to think it's something else now. We live in the Phoenix area so it has never been exposed to snow. I read somewhere where the Colorado has a chronic problem with the exhaust valve springs causing the check engine light to appear. Is that true? She's stopping at AutoZone on the way home work today to have them check the diagnostic code. Any help will be appreciated.

Thanks

Yes, the 3.5L is known to have valve and head issues. It occurs in a few trucks. GM has increased the valvetrain warranty on the heads and valves to 100,000 miles.Typical code is P0300 engine misfire.

Thanks Dan. I'm taking it back to the dealer tomorrow night. They'll check it out on Saturday. I'll ask them what the code is. My wife took it to Checker auto after work and they wanted to charge her $220 dollar deposit to use the code checker over night. (code checker? what do you call these things anyway)

:lol:

Code scanner or OBDII scanner

I hope it's not the dreaded head/valve issue.I know of some trucks that have surpassed the 100k mile marker and have not had any issues.

"Code scanner"! That makes since (yea I know - I suck)

Now she's telling me (my wife) that the truck seems to rev up when she starts it - no she doesn't press the gas pedal - yes the check engine light is still on. I noticed last summer when we would turn the key to start and then release the key once it was started, the starter would stay engaged as though the ignition system was screwed up. Took it to the dealer and they replaced the ignition switch. She seems to think some of this is still happening. I think it's all interrelated and the computer is simply getting confused. Hopefully it's nothing to serious, I really like the I5 engine. Fortunately it's still under extended warranty!
I had the I6 in my Trailblazer (which I traded 3 months ago). That was a great vehicle but I wanted to trade it while it still had value.

Thanks for your help!

[brucertl]

I got my wife's Colorado back on Saturday. Chevy said the code indicated a vacuum leak. They filled the system with smoke and found the smoke escaping from the gas cap. Apparently Chevy had a recall on that cap and they replaced it for nothing. They reset everything and so far all is good. I'll keep my fingers crossed this time. Thanks for everyone's help.

Was visiting relatives in Las Vegas a couple weeks ago and they have a 2007 H3 with the I-5. The H3 is kind of heavy and it seemed to be struggling to run it up some of the hills. What are they rated at? GM calls it's "code scanner" a Tech2

[Pete95Sierra]

those 3.5L I-5's are rated at 220 horse 220 torque....not very much to move a big car like the H3... although GM just came out with the new 3.7L I-5 which gives it 20 more horse I think that is going in the colorados and H3's.... finally they got smart tho and put the 5.3L V8 in the H-3 Alpha which gets 305 horse

[goleee33]

I really can't wait til they come out with the V8 colorado, thats gonna be very nice truck and update the interior a bit.

[Steve]

The V-6 and I-6s that have been developed in the last 5-10 years are just as powerful as the V-8s were a generation ago.

[Big G]

From what I've heard, the I-5 in the Hummer is going to be replaced by the 3.6 V6 in 2009. This will mean the eventual loss of these engines in the Colorado/Canyon. The V6 is supposedly the same one that's in the CTS but less horsepower.

[Aeropagus]

That's a good question. Engines are so much better built these days that I'm not sure it's going to make all that much difference.

[Steve]

reviving this old thread. :great:

[05Xtreme]

Hey guys, I have the 2005 Colorado Xtreme with the I-5 engine, I was planning on putting a cold air intake, and a throttle body spacer on. But besides that, does anyone know if high compression pistons will help me quite a bit, or should i just wait for the supercharger, and build from that?

:sign0016:


CAI is good. There are offerings from AEM, K&N, Volant and a few others
TB spacer is just a paper weight on these trucks unless you plan on tapping threads into it for a nitrous injector. They don't really offer any neasurable gains
The 3.5L has 10.5:1 compression already. I don't think anyone has come out with performance internal parts for these trucks
Supercharger, well, RKSport had a kit, Wheel-2-Wheel (W2W) made a kit for the 3.5L/3.7L Hummer H3 that also fit on these trucks but have since gone out of business. Vortech lists a superchager kit for the 3.7L if you are willing to pony up the $5500
