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.

RE: Re: I-5 engine mods

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

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.

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?

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.
