pre s/c or nitrous

Rebelli0n · #1 07-03-2005, 07:44 PM

Alright, you guys are probably going to laugh at me for asking this but oh well im a newb. Anyways, i was thinking about getting a supercharger or nitrous. My question is what should i do to my engine (2.2L ecotech DOHC) before i get this kind of hardware. Because from what i am hearing its pretty bad to put those kind of things on a stock engine, and i can see the logic in that but what would i need to do to prep for those kind of upgrades?

I never will understand why some people want to get right down to it and skip all the fore play. The way I see it just jumping right to either N20, super charged or turbo takes all the fun out of things really. Im going to dump everything I can on building my engine N/A with everything I can think of and even the things that frankly make no sense. By the time Im done with all that maybe Ill go to being boosted or shots. Who knows, you may be able to come up with enough N/A equipment to make up the difference between boost or shot but you never know til you try. Even then once all the fun of that is all done at least if youve done things the smart way all your internals should be built up enough that you shouldnt even have to ask this question you can just do it.

Speed without the adventure of trial and error as well as the little hardships that come from trying to get good speed out of an N/A engine frankly to me is just a waste.

Thats just my 2 cents anyways.

Not everyone can afford "all the little hardships". Though to counter my own statement, if you can't afford to, don't.

so what are you trying to say? its better to spend 2 grand on minor bolts ons, IE Intake, Exhaust, Header, Mounts, Pulleys, TB, and such and get like 20 more HP If that. Or spend 2 grand on a supercharger, get about 50 MOre HP, then start adding all your little extras if you feel like it.

FOr the most part, NA tuning on cavaliers is a waste of money. Unless your doing internals, why bother? Its better just to jump right into forced induction than play around with all that ebay crap.

I never will believe that going n/a is a waste of time. Ok the only time I see on your cardomain is a 14.7 with the s/c on it. My buddy dan with the same z24 and he is n/a with not alot of mods has his time listed at around 15.2. So either n/a can work if done right, his slip listing is a lie, or you need to learn how to drive that sucker better. And no Im not saying you dont know how to drive your car Im just saying that doesnt sound right running at 7psi with a z24 and only hitting 14.7.

And for the record. You didnt get any attitude so why try and give one?

uhh that was 14.7 with 4.5 PSI and just the supercharger added. Before when i was NA my best was a 16.1. And its not very hard to drive an automatic. Further more, half a second is alot of time to make up. Also you dont know this, but the faster you go in the 1/4 mile, the more HP it takes to improve just as much as before. Lets say you need 5 HP to go from a 16.0 to a 15.8. Well if you want to drop your time from a 15.0 to a 14.8, its gonna require more like 10 HP. If you want to go from like a 14.0 to a 13.8 is gonna require around 15 more HP. The faster you are, the harder it is to go even faster.

Also why bolt ons are mostly a waste for a NA 4 cylinder car is because 4 cylinder cars are already very good at breathing. Intake, exhaust, headers, all done on a stock car dont do much at all. Now if you port and polish the head thats a different story, but thats not a bolt on. BUt even that has its limits. You can do alotmore to a car with 2500 invested in forced induction that you can do with 2500 invested into a NA tune.

PsychoJJ · #7 07-06-2005, 12:03 AM

Well considering this is not only my daily driver but my familys only car that means I cant affored to take the chance on running it boosted so to me, no, going n/a and doing all the little bs isnt pointless. Also I wasnt talking about just bolt ons. I plan on doing everything you can n/a from port and polish, head work, bigger throttle body and things off other ecotec engines that are not on the cavi eco that will help as well such as a certain intake mani that will remain nameless.

wow...why would you even race your family's car?? and nitrous oxide is more dangerous than a supercharger or turbo....

I guess it just depends on what you want to do to the car. Meaning what end result you want.

Can you get a charger for 2grand for an ecotec? Because that's what the poster has, and I've looked and can't find one near that cheap.

-Jayson- · #11 07-06-2005, 12:24 PM

when the GM charger comes out for the ecotec, which should be very soon. It will cost between 2300-2600. The price isnt finial but somewhere in that range.

You can if you know some people. Or if you know some people that know some people that walk the dog of a person that knows this one guy that can get the number of a guy and all the while it turns out its the guy next door.

EDIT: Jason, did they put out final numbers that it will produce? Ive seen everything from 170 to damn 230 but I have yet to see concrete numbers.

-Jayson- · #13 07-06-2005, 02:57 PM

nope, but honestly i think 175 is about right. The M62 supercharger is designed for med-large displacement V6 engines. The supercharger is way oversized for that engine, so it prolly drains a ton of HP from the engine.

Rebelli0n · #14 07-06-2005, 10:11 PM

sorry i am a new person at this... what all do you mean when you say "internals"

175 at the front wheels or at the crank? If it's at the crank, I definately am not going to justify 3,000+ after install for 35 horses.
