big horsepower?

[rcolt75]

Just wanted to see if anybody has beefed up a cavalier yet and gotten some real hp out of it. I have 2003 2 door and i'm thinking about either turbo charging it or supercharging it and doing some major internal work to it plus upgrading the brakes and possibly puttings some 18 or 19 inch wheels on it. My cavalier has about 145hp right now, i was just wondering if anybody was up close to 300 or maybe more.

Unfortunately most people are going for looks, spending all of the money on bodykits etc. If you put larger brakes (although they will be needed with that kind of grunt) and 18s or 19s you will lose some of the power. Is this all for the street or are you planning to Autocross it? You haven't said what motor ou have but I would say 300 is possible. It may not be 100% reliable though. If you have a 2.2 then you would probably need to port and polish the head, fit harder valve springs and say Stainless steel Valves, Some Lower compression pystons and forged rods possibly oversized just for a little more displacement. I'm not sure how tha crank would hold out but would probably be worth investing in a Nitrided unit. You would need the exhaust manifold and intake. a mediun sized turbo a boost controller and a good Blow Off Valve and not just for the sound.
Check http://www.importperformanceparts.net/ for their Turbo Kit It can run up to 18 pounds of boost with the Garret T28BB upgrade. A large Turbo which will give a fair amount of 'lag'. Although you will need to run this kind of boost or most probably higher for 300hp Or their Kit with the T25BB, a slightly smaller unit that they claim will give 280hp without further improvements so 300hp should be possible with this kit, Usually the T28 is used by Rally teams but they have sofisticated Anti-lag systems that greatly reduce the life of the turbo. These work by controlling the ignition. When the driver eases off the throttle pedal instead of the throttle butterfly closing completely it remains open meaning that air is still entering and exiting the engine and the ignition cut the spark so that the power output is lowered to simulate lower revs, this keeps the Turbo spooled up and then when you hit the throttle pedal again the boost is there waiting for you and then instant power with no lag. What this does though is cause unburnt fuel to enter the exhaust and this results in flames being spouted from the tailpipe with a bang or pop. You would also need some kind of LSD as this much power through the front wheels without one will just mean that you don't go anywhere and just go through tiresa set a week!!!

Good Luck though $$$$$$!!!!!!! Would forecast near $10,000 in engine mods when you're done (tax & hidden costs included)

Oh my God where do you get all of your information? man im gonna have to start taking notes every time you post lol or start printing pages because this is stuff a lot of people would probably want to klnow... oh and by the way, whats the max power concieveaby done to a 2001 Z24?

[-Jayson-]

a stock Z24 can handle around 250 HP before you need to start replacing things like transmissions, driveshafts, pistons, and all the other things that go along with big power. As far as how many HP you can get, well that depends on how deep your wallet goes. Speed cost money and thats the bottom line. With enough money im sure you can make your Z24 have 1,000 HP.

I don't really realise what I know until I get started on something. Concieveably you could run over 1000hp out of a 2.4litre engine but for the kind of money that would cost you may as well put your name down for a Lamborghini Gallardo. You see most people want 300hp from 'bolt-on' parts. If you really want High Outputs then you have to go to specialists in order to squezze every last hp out of a motor. If you wanted to see 1000 + hp out of a 2.4 four cylinder it wouln't really be anythin but the block and head casings that would even resmble the original. You would probably have to bore it out and then put a treated sleeve in there to keep you pystons from coming through the block you would have to search high and low for someone to build you a crank to handle it and then you need to consider, clutch, trans and driveshafts. It would be possible but not worth the bother. Not unless you had shares in a transmission company!! Some drag racers can run 1000+hp out of 1.8 Honda units. Nobody say anything about V-Tec. It makes me laugh when Honda drinving dipshits put graphics on the side Saying V-Tec Powered! That's like saying 'My car makes good power but I have a specail system that allows my to save gas when I drive to work at McDonalds' As after-all this is all it does, along with any variable valve lift or timing system. It allows for good power numbers while maintaining good economy!! That's it! VVTi (Toyota) Valvetronic (BMW) etc etc

You must have posted that while i was typing as the hotmail flashed up.

Also about the 250hp, it depens on how you drive it!! I'm not talking about Driving miss daiy as opposed to like you stole it but you skill level with feeding power and clutch control!!!

Finnese is the name of the game not just Fast and Furious style rinsing the car for all it's worth!! I f**king hate thoise stupid movies! I'm all for car movies but not when it may as well have been written by the top columnists at cosmopolitan, it's complete bollox!!!!

OMG... thats one of the best things i've heard in a while

[noshun]

I aim to amuse! you put my typo's in your sig dude. If I weren't do tired I'd be laughing! Thanks for that complement though!

[big dude1]

Cool thanks... my wallet aint deep enough to make a 1000 hp and if i DID want that much id go buy something like a viper or a corvette... but thanks for the info...

Thanks for the info. The 18's or 19's will be part of the look so I guess I'm going to have to sacrafice some speed unless they make some really lightweight rim in those sizes. My cavy is a 2003 with a 2.2 eco, probably going to be all for the streets. So you think I should go with a turbo instead of a supercharger? I've been doing some homework and it seems the turbo kits are going for around $4k and the chargers around $5.4K. What do you think about upgrading the cams? Right now I'm just getting some ideas of where to start, I'm think of going with the turbo or charger first and leaving it set at between 6-8psi until I beef up the internal parts, which I think is safe for the factory parts on my engine. thanks again.

well if your going for big HP numbers id say go with a turbo. Just alot easier to fine tune and get more boost out of.

Cams Would mainly benefit a car that it tuned for NA performane. They rarely are worth their money on a Turbo application unless it is a cam that is profiled for Turbo specific applications which are rare to say the least

What kind of wear and tear would a turbo do to an engine not designed to handle one, such as a cavi?

It's not so much wear as just damage. You are fine on a low pressure system (around 6 psi) but you wont want it to stay there for too long! Detonation is a pretty big on where the mixture leans out and this car damage just about everything in the combustion chamber. Weaks ring can be damaged causing blow-by and if the oil isn't changed regularly enough then catastropic turbo failure resulting in peaices of compressor turbing and turbo casing entering the combustion chamber. This usally is a junk the whole engine kind of deal! But this is only if you run the boost too high! There isn't a line to say,' You can't run above ***PSI with whatever motor' as it depends on mileage, they way the car has been driven etc! If I was going to boost a motor over 5 years old even low miler I'd do all the pistons rods and rings. Also you could snap a weak crank or lose the big end from a rod! Not good either way!!
