NJHK, GM did a P&P head and spent some damn good money on it. They only got 5whp in return for a couple grand in work. The only real power you would see from that would be around 400+whp where the stock head starts to become a restriction. Sure the rev limiter being raised would be nice to make some more power, but the blower can onlt spin so fast. I'm sure camshafts and an upgraded valvetrain would give about 20whp or so, but were looking for 350whp here and a bigger blower will be necessary. However, I don't think the M90 is a good upgrade. A twinscrew is where it is at.

 

Porting is one thing but camshaft changes and actual computer tuning is another thing. Swapping onto a ported head isn't going to give you instant power without making changes in other places.

 

Another thing, the reason I say this as far as your valvetrain being the key to making good power is cause I can give you an example of someone who has an automatic cavalier, 2.2 ecotec, besides bolt ons, he upgraded the whole valvetrain system, running nice comp cams n/a and making big power...and he's automatic. That's not the full thing though...he's running a standalone unit. Tuning is key.

If you want to know who I'm talking about, it's Fred from SMG Motoring.



If you don't believe me, he'll tell you how a good valvetrain system and tuning can go a long way.

 

i talked to whipple is well they are not going to make a twin screw kit for our cars, which sucks. And yes twin screw is the way to go.

 

Has anyone looked into using one of these units? I know that someone said the 1.3L isn't sold outside of the kit, but sometimes finding a used one is possible....

 

Good luck with that one. It's like finding a needle in a haystack. Trust me!

 

ok so why dont we us as a community get something going on it then? I mean seriously why dont we the people who are actually serious on doing a swap put money together or something to get this going? Granted this probably me talking out my ass, but also its been known for people to say yea now, but later when they produce something poeple will say no cause of price.

 

well lets seriously THINK and DECIDE what would be the best route to go with this thing i mean cams and all are nice but im not doing that to my car haha you know anyone in texas that knows whats going on with a cam on an ecotec HAHAHA youd be lucky to find 5 ss/sc with mods much less people with experience working on ecotecs id be the cam guinipig and its already happened and it ended up with me at the dealer out of a 3.8 L s/c engine that luckily i got warranteed not an option im not doing valvetrain end of story!!!!!!!!!!!!!

 

I've been working on it myself, but having trouble finding time to work on it and vendors willing to work with me. It's coming close though. I'm hoping in the next few months I'll have a prototype of some sort. Looking at spending about $4k-$5k for my prototype, but after that I hope to be able to sell something around $3k-$4k. That's assuming nothing bad happens. A blown engine would raise the proto type cost.

 

well what i was thinking, as i conglomerate maybe the vendors would take us at least some what more serious. I mean they would be some what stupid not to create something for x,xxx amount of people if everyone and i mean everyone that is serious and willing to put 100% behind this effort. I dunno guess just everyone will do there own thing, but id definetly be intrested in stuffing a whipple under my hood.

 

No offense but if a good mechanic can't do the job, than evidentally he's not a good mechanic. When I had my sunfire, I used to go to all types of "performance" shops who mainly worked on import cars and they called themselves "pros" but wouldn't even touch my car cause they said "we need a certain tool that GM has". I found an Engine Rebuilder shop in my town that only rebuilds motors of all kinds...I brought my car there, did the job no problems no questions. The ECOTEC motor isn't some far out concepted motor that has a mystical valvetrain unit, it's an 4 cylinder economy motor. Working on them has been said to be a bit more tedious but that's it.

Don't keep from doing the right thing cause you had one bad experience. Find someone who knows what they are doing.

Like most of the guys here have said, changing to another supercharger isn't going to help much and lowering to the smallest pulley isn't going to get you that far...if you want real power, you're either going to have to take off that supercharger or start working on that motor.

 

sounds like the grand prix all over again

does this look like a fitter?

 

Drkknight, I'm a bit confussed as to what you're trying to rally up...

Are you trying to rally up someone to develop a supercharger for your car or for you to somehow use another supercharger? I'm sorry, just confussed.

 

No i was just browsing ebay now and wondering if it could be a good fit for my car. that link above shows one. As for my previous posts, i was just giving an idea out. I mean if people want to get a new blower to put on, why not rally together? dunno just an idea thats all.

 

Well I'm just trying to get to the point of there isn't an ECOTEC Performance shop you're ever going to find. Sorry but it's just not that popular.

Also, if you're not satisfied with the supercharger you guys have, this is something you should have anticipated before hand of buying your cars. It's one thing to buy your car and say "I plan on doing this and this" and another to buy it and say "I want another supercharger cause this isn't getting me anywhere".

That's my take on it anyways.

 

As much as rallying together can help, this might be a lost cause for a couple reasons...

1. There is a small amount of you who would actually care enough to do so
2. There is such a small aftermarket as far as Cobalts go, especially cause there is a small amount of people who own the SS/SC models.
3. It's one thing to rally and get Injen to make an intake for you guys (just an example) and another to have a company that doesn't deal with your motor specifically to develop something as complicated as a supercharger.

Not saying rallying together doesn't work, i've seen it happen w/HP Tuners and the J-Body forums but just saying this is another league. A company would really have to see a huge aftermarket as far as guys who want a better supercharger to spend money on R & D to do so. Demand is what drives companies, when there is no demand, there are no products.

 

i know i wanted an srt4 but srt4's were discontinued i needed to buy a NEW car not a used one **** there is this guy selling a yellow srt with 25,000 miles it has at least 4,000 worth of mods on it including rims (black) and he only wants 13,000 i just couldnt get the loan thats a steal if ive ever heard of one he was getting deployed and didnt want the payment , is there ANY chance of a turbo swap and how hard im not searching for this either

 

Ive seen it happen time and time again. I remember back in the day when i had my accord, and all the v6r's were bitcing and whining that they dindt chips out for their car, then finally one day superchips or some company comes out with one, and barely anyone that wanted one bought it.

 

EXACTLY!

I mean seriously, how many people you know with an SS/SC who is even willing to buy another supercharger and put it on their car in disregard of their warranty and money? Very very few.

Not trying to start anything but it's the same situation with everyone on here complaining how there is no turbo kits available and having to wait for Hahn...how many of these people are seriously going to spend $4,000 straight up for a Turbo kit for their Cobalt? It's going to be far and few in between.

People like having stuff available for them but in reality, they are more than likely not going to buy even half the parts that are available. I've been on forums a long time and I don't know how many times I see the people who say "yeah I just bought my (enter car) and I plan on doing a turbo setup with full forged internals, cams, head port job and looking for 400+ HP" and then we never hear about these people ever again. Why? Cause it's all talk, no show. It's easy to sit back and say I'm gonna do this and do this than it is to actually dish out the money and have a plan to do something.

 

You can always go custom.

And no offense but not having any motivation to look things up won't get you anywhere. There is plenty of information to learn out there, it's not always going to come to you.

 

yea but every turbo thread is a laughing stock ive done my research at least on this site and its not taking me anywhere but the begining if i were to do a custom turbo swap how much total do you think all that would cost

 

Yeah, you definitely pulled it out of your ass like you said unless you're meaning twinscrews only:
1. A larger displacement supercharger obviously offers more HP potential.Not true...it is ONLY when it can offer more cfm...M90s don't but maybe maybe 50 more cfm...MAYBE
2. It runs cooler because it spins slower. Not true...it is based off of how much boost is there...for it to run cooler and spin slower, you have to make it put out an equal cfm or larger at a lower level of boost...M90s don't.
3. Bearing speed friction and oil temperature are reduced.Refer back to #2 for the blower speed and the oil temp doesn't matter except for how often you have to change it (50k miles) since it is a self contained oil system...if it was pulling oil out of the crank case, that would be different.
4. Cooler air charge temperature. Only if you're looking at a twin screw because the M90 doesn't put out more cfm at equal boost levels where it would be worth while.
5. Lower parasitic loss (less engine HP to spin). M90 requires 20hp more at top end than M62.
6. Larger pulleys have more surface area for less belt slippage and wear.That is only viable info if you are using a large rib belt, like an 8 or 10 rib which is very costly because you would have to change all the other pulleys on the engine to hold that large of a rib belt...ours are only for 6 rib...we have a decent tensioner, along with the ability to purchase a larger idler pulley and idler pulley adjustable tensioners so with what we have available, belt slippage isn't an issue...

 

I've done a write up of what you need for a custom setup. What questions do you want answered? Prices, no one can answer that, it depends on what you buy, what parts you use, where you get it from...the list goes on.

 

You know you can just use the exhaust manifold off of a SAAB 9-3 2.0t?
