  • ION turbo

    anyone know what kind of boost (super, or turbo) the ecotec can handle? the 2.4L specifically, but whatever knowledge you guys have, could you pass it on? thx

    should be safe around 5-7psi.

      the redline is boosted to 12 psi. is the engine block or manifolds reinforced to withstand this? it's still the same engine as the 2.2 or 2.4L right? how can it take so much boost? sorry if i'm being a retard

        i know the 2.0 is GMs 4cyl drag engine thats why,and they knew they were going to put a SC on the redline/SS

          so the 2.0 is a specified race engine? ok, that would explain it. so 5-7 psi is the highest anyone would reccomend? any opinions between SC or TC? it's my daily driver, but I want to have some fun with it too. Light to light racing mostly, but a bit on the highway and maybe the strip

            no the 2.0 just has some forged internails like pistons and maybe conectiong rods but thats it i think. if you prep the engine right you can throw what ever you want at it. its all in the preperation. the 2.0 and 2.2 are damn near identicle.

            Consider this: 800 hp is a lot on a 2.0L motor. With 750hp, three-quarters of a thousand you're basically dealing with 6.14 hp per cubic inch. Pressures and stresses of all kinds thermal and mechanical loading across the board escalate to extreme levels. A Chevrolet 5.7-liter LS1 V8 with this much specific power (horsepower per cubic inch) would be making 2,137 hp

              2.0 comes stock to handle boost and higher hp levels (i.e. forged rods and pistons, sodium valves, oil squirters, etc.)

              the 2.2 and 2.4 ARE NOT IN STOCK FORM GOING TO WITHSTAND HIGH HP LEVELS AND MAJOR ROTATING ASSEMBLY PARTS WILL FAIL AROUND 280-300HP. this has been discussed many times on different forums, I thought this one was included, so there it is in caps so it stands out if someone decides to search.

              I wouldn't go with more than 5-7, maybe 10 psi depending on the turbo and management for fuel and spark.

              honestly, if your'e more into light to light and some highway or strip once in a while, why are you not considering nitrous? I'm not trying to talk you out of turbo or superchargers, but I recommend weighing out all your options. research them all.

                no matter what, tuning will make or break your setup, what are you planning to do in terms of that?

                yeah I know, I didn't edit my post, damn nazi mods LOL

                  I'm not entirely sure of how/what I want to set up. I just know that there's only so far you can go with a naturally aspirated car. Want to prepare for that next step when it comes along.
                  as far as nitrous, i've looked at it a little bit, but I guess I just haven't researched it enough to know what it's good for or if it's worth the time and money.
                  I'm still learning with this whole car thing, until about a year ago, i didn't even know how to change my oil, so forgive me for being a little slow on the uptake man.
                  Still, any thanks for your thoughts, and any more you might have. I'd like for my brand new 2.4L QC to be kicking some major ass within the next year or so!

                    Ya nitrous is good if your safe about it.

                    Like buying all the safety stuff, like a rpm window.

                    I was going to do juice but I didn't want to refill every so often.

                    Right now i'm making myself a home made turbo project

                      I think the 2.4 head has the same bolt pattern as the 2.2/2.0. Atleast that is what I inffered from V-man.

                        i agree with the 5-7 thats your average for any stock engine. not enough to really start blowin shish up. not bad gains with 10:1 compression either...the 2.0 has the forged internals plus thick ass cyl walls since its the same ecotec just not bored out as in the 2.2 and the 2.4 which is obviously gonna have the thinest/weakest cyl walls. i don't know if gm sleeved them or not so i can't say...

                          they should all either have different sleeves to make up for bore changes, if there are any, but I think all GM did was change the stroke at the crank, espeically considering you can use 2.0 rods and pistons with the 2.2 (is recommended actually in the latest handbook on the ecotec).

                          as a matter of fact, aside from teh oil squirters on teh 2.0, all the blocks are the same.

                            just wanna verify i read correctly, the forged rods and pistons from the 2.0 will work with the 2.2?

                              the power limitations of the LSJ rods is still "fuzzy" as far as a definite answer. GM recommends them for those not going much over 300hp, but I have heard rumors in excess of 450hp.

                              for the cost of new 2.0 rods, I wouldn't use them unless they feel into my lap, since you can get forged goodies real cheap that will hold +500hp.
