turbos

[kane322]

what are the different types of turbo's you can get?

[Mouse]

Depends on your wheels.

[Dr.Dan]

By 'types' of turbos, do you mean brand names like Garrett or KKK? or size (has nothing to do with 'type' though) ??

Sizing of the turbine and the compressor are totall dependant on the needs and application.

So, please explain just what it is that you want to know...

[kane322]

well, I wanna get a turbo for my cavaliar but I don't know what turbo to get.

[Dr.Dan]

Well, what are you doing to the engine? What's your budget?

Even the most basic system on a stock engine with low boost is going to set you back $4000 to $5000 once you get your ECU reprogrammed, all the plumbing, turbo, exhaust, etc, etc...

If you want lots of boost to make some real power and you're going to do up the engine to handle it, then you're looking at $8000+++

It's not just as simple as bolting on a turbo and away you go.

If you have an older (pre 95) Cav, you could find a 2 litre turbo engine (with harness and ECU) and you'd have a good start... then you can tweek that one a bit ;)

Too many options... not enough info...

If you really want to know all the info you need for *your* car, I'd search out a good board that all they deal with is modding Cavilier / Sunbirds.

And your windshield too, leaving only two eye holes to see out to the road! :eri:

[kane322]

wow I thought it would only cost a couple hundred not a few grand.

[Dr.Dan]

Hahaaaaaaaaaa..... :eri:

You can buy a blown turbo for a couple hundred... and pay another $2-300 to rebuild it.
Again, that's just the turbine/ compressor... you still need allot of other parts too... and many many hours of 'making things fit'

Heh, yeah, the general rule of thumb with a DIY turbo is to figure out how much it'll cost you and how long it'll take and then double it. A friend of mine is turboing his Miata by himself. He's about half done and has spent about $4000 US so far. That's still about $1000 US less then a complete off the shelf kit though.

[Steve]

it wont cost 8g's to turbo ur cav, but it will still cost about 5. there are a few companies making turbo kits for cavs, also, rsm and gm have a supercharger for a cav. might wanna check that out before jumping to a turbo.

[Dr.Dan]

It will if you want to make allot of power... which is what I had said...
You'd have to build up the engine to handle the higher boost
Not to mention the larger injectors and high volume fuel pump needed for a high HP application.

None the less, he's not going to turbo it for a couple hundred $$$ :D

[Steve]

no not a couple hundred. but ya, it wont be 8g's. if he can settle for low psi, then its not that bad and most of the internals can be stock, which the exception of fi, pump, and all the other essential parts that need to be changed to handle it. but if he does go to high psi and expect a lot of power then yes itll be up there by the time you upgrade all ur internals. i suggest a supercharger. the gm can be run with a bone stock engine and has a warranty. cant go wrong. ud look at about a little less the 200hp/200tq with the sc.

If you go back to post #5 you'll that is what I said :ght:

I don't think you're going to stuff a 3.8 SC under the hood of a Cavilier :mbx:

[Mouse]

Hood, he don't need no stinkin' hood. ;)

[Steve]

I don't think you're going to stuff a 3.8 SC under the hood of a Cavilier :mbx:

actually, yes you can; but i wasnt talking about the 3800 s/c, i meant the gm charger.

heres a 98 cav with the 3800 s/c engine

In case hot linking is prevented again on the second picture. :)

Hmmm... interesting... but we don't know what era he's got to start with ... it could be a pre-95 Cav.

And what is the price tag that goes along with one of those SC for the newer Cav and Sunfire? I'm sure they aren't cheap....

[Dr.Dan]

It doesn't cover too many years... and I'm yet to find the pricing on this kit... but this is what I've found from http://www.gmgoodwrench.com/perfpartsjsp/partlist.jsp?cat=14253&section=ep so far.

12498287 2.4L Twin Cam Supercharger
Application:
2000 - 2002 Chevrolet Cavalier 2.4 L (RPO - LD9) with Manual Transaxle (RPO- M86)
2000 - 2002 Chevrolet Cavalier 2.4L (RPO - LD9) with Manual Transaxle (RPO - M94)

2000 - 2002 Pontiac Sunfire 2.4L (RPO - LD9) with Manual Transaxle (RPO - M94)
This integral "roots-type" supercharger and manifold design was developed to maximize both engine horsepower and torque without sacrificing durability. Vehicle Control Module (VCM) calibration is a key factor in both performance and driveability. This supercharger has its own unique calibration designed specifically for 2000 to 2002 model year 2.4L Twin Cam engines. Being an integral design gives the supercharger a "clean" factory look and more importantly, it's GM factory engineered. The GM Performance Part kit is the only supercharger that has met GM Engineering standards. The 2.4L Twin Cam Supercharger has undergone more extensive testing and tuning than any other power-adding device. If your goal is to make a reliable 190 HP and add over 40 lb/ft of torque with your 2.4 Twin Cam, this is the only way to go. The end result is a reliable, compact powertrain that has more power than many V6 engines.


The kit includes:
- All mounting brackets and all mounting fasteners required for installation.
- All air ducts and adapters including new PCV hoses, baffle and tubes required for installation.
- Gen II Map Sensor, four spark plugs, accessory drive belt required for installation.
- Recalibration of the Vehicle Control Module (VCM) is also included in the kit.


Easy Installation:
Normal technician's hand tools are all that's required to install this supercharger kit (recalibration of the on-board vehicle control module must be done at an authorized GM dealership). Skilled technicians can easily complete a full installation in a single day.


The 2.4L Twin Cam Supercharger Kit carries a warranty covering the complete kit for defects in material and workmanship for a period of 12 months or 12,000 miles from date of installation. In addition to the product warranty, this supercharger kit will cover the powertrain (internally lubricated engine and transmission components) for the length of the original factory powertrain warranty. For specific details contact your local GM Performance Parts dealer.

[Steve]

the gm kit can be purchased from anywhere from 2800 (if you know the right people) to 5 grand. there are a couple alternatives, rsm makes a s/c kit aswell which is as good if not better then the gm one.

www.rsmracing.com
www.highrevmotorsports.com

that s/c for the 00-02 does fit the 95-99 aswell, as they are both the same 2.4l engine. and a 2.2 ecotec s/c is currently being developed.

[kane322]

well, I really don't have that kind of money so, sc and turbo kits are out of the question for me now. :( . how much of a performance difference do headers make?

[Steve]

cavaliers only have one header, not headers. it will give you some gains, but as far as air flow, its only as weak as its restrictive point. to see some real gains, youd have to upgrade all aspects of the airflow system. which means intake, header, and full exaust. this way ull see the most gains.

[Dr.Dan]

Yep, exactly as steve said... you gotta do the whole thing to see (feel) any improvements.
But if you do it all, you could see up to a 10% improvment :)

good write up on j-body performance mods

[kane322]

Well I already have a warm air intake system, plus a performance and very loud exaust.

[Mr. Apollo]

OK, honestly, you have a Cavalier. Just save up any money you want to dump into the Cavalier making it a faster car for your next car. I realize you want to make it cool and everything, hell I was the same way when I was younger, but I qucikly realized that it was better to save the money I had until I got a car that was capable of going fast and handling well.

Besides making a lot of noise your exhaust system probably isn't doing much else. As stated above you'll need a proper intake, a header, FULL exhaust (not cat back), maybe proted and polished heads and a proper tune to see a slight difference.

[Steve]

whats the diff wether he had a cavalier or a civic? im guessing a civic would be acceptable to mod, yet a cav, hell no.

[Mr. Apollo]

What? No, they're both as silly to mod.

[Jackthemeangiant]

If you want something faster and more fun, buy a motorcycle, you won't regret it :)

[Steve]

if you like ur car and enjoy it, mod it, dont listen to others, its ur car.

[Mr. Apollo]

You're absolutely right. In the end it is his car and money. I'm just saying that economy cars aren't the greatest platform to start with. If you're just interested in appearance mods then fine go crazy. Just please don't be one of those people that believes that each sticker they put on their car adds 15 horsepower.

[Mouse]

Like the stickers that say I have anti-theft devices installed??? ;)

[Mr. Apollo]

Like the stickers that say I have anti-theft devices installed??? ;)
No, those only add 5 horsepower.
