ive looked for a turbo for some time for my 2.2l and i cant seem to find one. now im not gonna pretend to know anything about turbos so if anyone has any hints or suggestions on how and what would be the best parts to piece together to make this work id appreciate it. i know the connecting rods arent that great for this car so if anyone knows anything about where to get better rods thatd be awesome. ive always owned trucks so owning this cavi is a new experience for me
thanks!!
read the sticky at the top of the boost forum, will tell you basically everything you need.
u said its a 02 z24, then u said 2.2l, typically the z24 would have the 2.4l, and if its not a z24 you would have the 2.2 ohv or the eco.
yeah everyones told me it should be a 2.4l. ive checked the vin numbers. it is actually a z24 and the motor vin number matches the car. its stumped me too. its an all aluminum ecotec so it cant be a regular cavi. i did some research and the 2002 and up have used the 2.2l as the base z24 motor. thanks for the reply im trying to get as much help as possible with this car as im new to the car world. thank you
Some canadian Z24s had the eco in 02 I've heard.
i got it at a used car lot so idk what the hell they did to it i just know it is actually a z24 according to the numbers. its definently faster than a stock cavi. it has the independent suspension and racing wheels and tires. the guy who sold it to me said the previous owner kept it stock and all the parts on it are original. ive been fooling around with it myself. ive already installed a motor monitor from jet performance and a chip from pcd. i cut the exhaust off behind the catalytic converter and ive been checking the oil pressure and oil temps to make sure it stays nice and cool even though theres no back pressure. i just replaced the oil filter and im looking for a good intercooler and radiator setup right now. im just dont know where to get connecting rods for it cause i read the sticky where it said gm didnt make the rods to go above 250 hp and ive already got it at 230 right now. im kinda worried about going further with performance until i replace those rods. if anyone could give me some advice on where to get rods at id appreciate it. thanks for the help.

So you riced it out. Congrats on ruining a perfectly good car. Your car does not have 230whp, it's actually alot closer to 130whp. The Jet thing and "chip" dont do jack @!#$ for making power.
Canadian Z/24s came with the 2.2L Ecotec. Also us eco guys snap wrist pins and ringlands before the rods. The best thing you can do is put the car back to stock, stop posting, and read everything you can on this site. After that then you can have the knowledge to reach 300-400hp and have a fun weekend economy car.

180hp in 1989 or 260hp in 2008, you decide. Quad < Ecotec

possibly an ohv powered car, but as for any other DOHC powered car (be it eco or ld9...) no it isn't.

it has the independent suspension
in the front it does, sure. but in the back, NO J BODY EVER had IRS unless it was swapped in from another car.

and racing wheels and tires. the guy who sold it to me said the previous owner kept it stock and all the parts on it are original.
j bodies also never came with "racing wheels and tires". so is it stock, or no?

ive been fooling around with it myself. ive already installed a motor monitor from jet performance
lol jet performance. do a search mate.

and a chip from pcd.
there is no such thing as a "chip" for an OBD-II j-car. sorry, you wasted your money on a resistor.

first off, why? second, backpressure is the enemy. you want as little of it as possible. you're confusing backpressure with scavenging effect. it's ok, people who don't know how internal combustion engines work often do this.

i just replaced the oil filter
just the filter? not the oil?

stock rad is pretty good piece of kit, handles fairly decent numbers.

allecotec.com, talk to Karo. highly respected member here. also, no way in hell are you running 230hp on a stock engine, naturally aspirated, with just a "chip" and a cut off exhaust. sorry, not gonna happen.

the specs on my car are stock 170 hp and 220 pounds on the front wheel. idk why everyone tries to argue this point. ill post a pic of the car and the motor just to prove people wrong. i got on here hoping for some good advice and 2 out of 4 people who replied to my post have denied what the car is. i know for a fact the car has more than 130 hp. and yes they did make a chip. pcd made it and they also make an oxygen sensor chip for my car too which i purchased but it fell off my car due to poor connections and not enough electrical tape. i also said i cut the exhaust off to get rid of my back pressure. so right now there is no back pressure on the motor. and yes the motor monitor is from jet performance it says so right on the edge of the screen and every time it turns on. all it does is monitor my manifold air pressure, oil temp and fuel mileage along with throttle position and other goodies. i appreciate the help but i dont need people with negativity replying to my posts. thank yall for all yalls help
from their website:
PCD Performance Chip Stage 1
The PCD Performance module simply wires into the factory harness of the IAT sensor.
The module will work with the sensor to provide a new signal to your vehicles ECU. The ECU then adjusts your air/fuel and timing advance curves to new performance settings. Our PCD Performance module eliminates costly parts and installation of ECU components, and still safely and legally provides the same end results.
you paid $70 for a $0.35 resistor that does pretty much nothing except make you DUMP MORE FUEL. these cars run rich as @!#$ stock, so all this does is lower you gas mileage and potentially burn up your cat. also, what manner of ecotec do you have that makes 170/220 stock? because gm never released such an engine. it's not negativity, its providing you with the information that you got wrong.

Ok your car is a 02 Z24 with a 2.2 Ecotec. We know this happened in some cars. Regardless your car does not have 170hp at the crank, or at the wheels.

then i stand corrected. sorry about that i just went off of what i was told. i dont have a dyno so i cant test the power on it. i pretty much spent that money for nothing then thinking it was a chip. i looked for a chip or programmer for a while and i couldnt find one so i appreciate someone telling me what the hell is up with that. i appreciate the help and constructive criticism yall have given me. like i said this is my first time in car world. oh btw its a 4dr z24. i just read 3 articles that said they dropped the 2.4ls in 2002 for the 2.2ls so the motor is correct on it.
yall were right about the horsepower. the articles said it generates 140 hp @ 5600 rpms

Reflashing the stock computer with a tuning program(HPTuners) is the only way to get a gain, but the only problem is that you wont see larger gains with your stock car.
2002 was the transitional year were the introduced the 2.2l L61 Ecotec(DOHC) and got ready to drop the 2.2L OHV LN2 and 2.4L LD9(DOHC).
Boost > N/A
180hp in 1989 or 260hp in 2008, you decide. Quad < Ecotec
how much of a gain should i expect to see from a reflashing of the stock computer? im not even sure what a reflashing is. im sure theres a sticky somewhere but since i have some people with knowledge givin me tips where can i get a reflashing done and how much could i expect it to cost?
HPTuners is a program you can run from a laptop to change setting in the computer to get more power. First you have to have the program which runs $600-750. Then you have to know what to do with it, which come with knowledge and experience. A lot of performance shops have HPTuners and will tune a car for a fee. Usually $300-600. Also many org members have HPT and will tune your car for a fee as well.
For tuning to be done properly it needs to be done with a wideband O2 sensor. Either you need to have your own, or the tuner needs to have one.
As for how much can be gained, well it depends on the motor and mods already done to it. I have seen 8 whp gained on a bone stock Ecotec. That is actually a good amount.

where can i find people who live in the east texas area? namely tyler or somewhere near that. i know eagle motorsports is right around the corner. that reflashing sounds like a lot of money for just a little gain. is it hazardous for the car in any way?
