Turbo Turbo...Im craving Turbo!

[Lefix]

Hmm dont know if you know this guy, but NJHK from the org told me that our 4t4oe auto tranny, or whatever the model number is, it is pretty strong, usually, heat is what kills the tranny, so im gonna buy a good tranny cooler, and it should last over 400-500 hp...

i didnt want to sound like a ass or whatever, but you've been dumping cold water on top of me ever since the second week after you helped me, so i dont know why you keep doing that...

Im not saying anything like "oh sucks for you guys cuz you guys are poor, college students, or you guys have to pay bills and shit like that"
Im lucky that my car is paid for, and im lucky that im still in highschool, and im lucky that i make over $1000 a month from working part time, so im not trying to say anything offensive, im here to turbocharge my car and all im looking for is help...thats all...

[Dr.Mambo666]

he was right on saying the 4t40e is a strong tranny but if u leave it stock its not gunna last u no matter how good of a tranny it is. U cant just slap a turbo on a car and expect nothing to happen.Somewhere down the road ur gunna blow something unless u build u car up to actually handle the excess pressure ur putitng on ur engine and tranny. Think thing through before you do this.If $4000 isnt cheap to you than i suggest getting your internals done b4 hand.

[Lefix]

This is my plan:

Complete my turbo setup for now, run my turbo setup at 7 PSI (which is SET by the internal wastegate), I have stainless steel IC pipings, they are stronger and lesser boost leak then typical aluminum pipings... Im going to have a 3" downpipe all the way back to my dual magnaflow exhausts...If im not satisfied with 7 PSI, which i dont think i will be... Then I'll save up another $1500, which would be quick, maybe around a month, then i will build up my engine with pistons, rods, rings, studs, etc...

I've already purchased a set of BRAND NEW Diamond Racing Pistons at 8.5:1 compression... Bought it for $200 for the set brand new... i bought it only cuz it was a GREAT deal...

Then im planning on getting a boost controller and turn the boost up to about 15 PSI, then if im still not satisfied with the result after 15-18 PSI, then im going to invest about $1500 in a GT Ball-bearing turbo and upgrade the injectors and do some hardcore tranny build...

But i think i should be pretty satisfied with 15 PSI of boost, that should push me about 320whp... and i think thats good for me...

wow, if you think $4000 is cheap, why dont you take that money, along with the rest of the money your gonna put in your car, sell your car, take ALL that money and buy a car thats actualy designed to go fast, instead of one thats desinged for economy, you'll get more respect too since, ya know, you wont be driving a sunfire (as opposed to a sports car)

[Schister66]

Think of this all as tough love...most people dont get my point or heed my advice until i literally beat it into their heads. Felix, you seem to finally be catching on. Your goals have become more realistic and concrete. On thing i will warn you about is the misunderstanding about the GT-R (BB CHRA) turbos. Most people think they are the "magic bullet" if you will. Your setup does not require one in order to make that kind of power. The ball bearing center housing has its place, but it is more important to match the flow of the engine to the turbo than it is to have a turbo with quick transient response.

Your auto tranny will last longer with the tranny cooler, but your torque converter is going to slip. They are a viscous coupler which doesnt actually attach directly at any point from engine to tranny. It simply isn't designed to handle the stresses of more power. If you were to eventually change out the torque converter, you'd be able to put more power to the ground without worry of failure. Heat is what will kill the tranny and when the TC starts slipping, substantially more heat will be produced. Another thing that your tranny will encounter is gear to gear shock. When your tranny shifts, it does it at a predetermined speed; whereas, i can somewhat slip the clutch if needed. That MAY be another thing to keep in mind.

Once you were to switch out the torque converter, you simply move the problem down the line. An auto tranny has 5-7 individual clutches that ease shifts like a manual. When those clutches are put under 200% more load, they're going to start slipping. It may not happen right away, but you can bet that they will eventually.

[Lefix]

Yes, thank you for your postive feedback..

I will see how Derk's turbonetic's internal gated turbo does, if it seems good, then i will just turn up the boost, but i know that there will be boost spikes and thats why i wanna get an external gated turbo.. But after i get my setup completed, which should be around the first week of october, when i have my first quarter break, then it should be completed within that week...

Im going to buy a wideband and HPTuner and i will tune the car with my mechanic's help... He has a 11 second ek and a 9 second crx, so he will know what to do.. he recommended me to get larger injectors, he said 550 should be good, i told him i should stay with 440cc and he was like okay whatever..

So, after i get my 7PSI boost setup complete with a good tune, i will drive my car, feel it, and see what i want to do with it... i will have enough money to build up the engine very soon... then im going to build up the tranny, yes i understand about the torque converter and also gear slipping, and i will ask this guy on the org, he has a 420+ whp sunfire, so i will ask him what kind of build he did and have him point me to some good tranny builds..

But for now, 7PSI is gonna be good enough for me...

My car was brand new, it costed $15000 brand new with 20 miles on it... i know that i can make it into a 12 second car, so i have absolutely no plan on selling it and getting another car... i have already put ALOT of time and hard work in it and i love my car... It can be as good and as fast as any other 4-cyl car out there...

[Schister66]

I'm glad you like your car, but it is going to take a lot to make it an 11 sec car. I'm finally getting into that range (on the stock engine) and it has taken a lot to get there....you have to remember suspension and all that good stuff too...

[Lefix]

Yup, i gotta do suspension like complete coil-over system, sway bars, strut and shocks, rear disc brake conversion...

I will probably be in college and dont have time to work on my car by the time i finish the 15+ PSI project, thats after the engine build, i dont know if im going to bring to car with me to college or not...

Meh, a 12 second sunfire, cavalier just doesn't sound right. I'm not sure what you mean by "as good and as fast as any other 4-cyl car out there." The Mazda RX-8(not a fan but still) is a 1.3L 4cyl and puts out 230hp. Your car is a 2.4L 4cyl and puts out 140. (stock). Blah i just don't know what to say, reading your very often changing plans, it looks like you're going to spend a lot of money especially if you plan to rebuild/rework everything.

Senior year coming up yeah? I'm in the same boat, but no job as you. But in my opinion i would rather use the money i recieve for having fun the last year. Saving for stuff during college, hell my friend went to University of Washington last year. Left his car at home (300 miles away) and took a bike just to save money. I can't see how a 12 second car will last you through college as a daily driver etc. Buying a car half way through college would put you far into debt, and that just isn't the right way to start off your left when you get out of it. Unless you're lucky and parents support you fully.

See i'm babying my cavalier because it's a 97, 175,000 miles? close to it? Parents used it to commute to the closest college for their masters, at seperate times, so it got miles chunked onto it fast. I'm not sure how far these go because anybody i know have many miles less then it, or have wrecked their cavaliers. I need this car to last me through college or until i can buy something else. I would love more power into the car, because when i look at my (not going to happen) dream car list, they're all HP monsters. Z06, M3 CSL, Fairlady Z, 911 Turbo. However i just think this is my first car and it needs to be just that, my first car.

Sorry for this wall of text, but i just can't quite understand why you really really want to go through with this.

[Lefix]

You are not a car enthusiast. You are someone who just wanna buy a fast car and done. You are not the type of person that like working on cars as a hobby, you want a fast car to go fast, your hobby is driving, not modding the car...

I am 17 and i currently have a part time job that pays over $1000 a month, my car has only 5000 miles on it and it is perfect for turbo... and i have a 4.0 GPA cumalative throughout highschool, i am in not worry to get a scholarship or aid's to get into college... I might end up going to NY and leaving my car in Hawaii, but i might end up going to the university in honolulu, in hawaii, and keep driving the car and have fun with it...

To make a ecotec a 12 second car isnt hard... a good T3/T4 turbo with a build up engine that is running about 15-20 PSI will get you about 350+whp no problem, and that will make it a 12 second car... When i said that i can make my car as fast as any other car is based on GM's 1200 HP 2.2L ecotec.

Now if you wanna buy a z06 and have 500 horses then fine, i will have my 350 hp I-4 car that cost 1/4 of what your car cost.

And you said that i've been changing my plans. I HAVEN'T, i had this turbocharging plan LONG time ago, i dont see how you came up with the idea of me having changing plans, but the plan is turbo, and that is like the ONLY plan i had.

Actually an Rx-8 has a 1.3L Rotary Engine, not a 4cyl the engine has 2 rotors n works way different. also his car would have a 2.2 not a 2.4

In a sense i agree, but i'm sure people say the same thing about me. I have put a lot of money into my GSR...it is a far better platform w/ a lot larger aftermarket following, but money is money. Its all about having a passion for something and putting your heart and soul into it.

Also the RX8 analogy was terrible. Not only are they not a 4cyl like previously stated, they also suck balls. RX8s are the biggest dissapointment out there...closely followed by most of Chevy's new SS badged cars

Yup I agree the Rx-8 should have been Turboed the cobalt SS looks pretty sweet tho

[Lefix]

When you are 17 and your mother bought you a 15000 brand new that is FULLY CASH PAID FOR, then im pretty sure you wont sell it and get another yet you wanna make it look aggressive and go fast, that is me, i have a sunfire and i wanna make it look anything but a sunfire and i want it fast so i can smoke imports, no offense to imports, and i do like them, but everyone here where i live on the island has imports, they dont like domestic...
