do a search on ccfiero350 .he is doing a build with the 2.0 supercharged ,f35 with LSD .he figured out how to make the cobalt axles work .i gotta admit though ,now that i have a turbo ,i wouldnt go with NA again .the spool up and the blow off , the fact that unless i want the boost the turbo just idles along is amazing to me . what i like the best is the third gear power .drop it down and hang on ! .
i have yet to own a supercharged car so i dont know whether they would be as much fun ,but how could 205 RWHP not be a blast?

i picked up a set of street dreams 1.25" drop spindles .i was going to wait till winter to put them on but i am on holidays and its too windy out to go boating so i decided to put them on .pretty simple install , but it does change you toe setting .i was hoping all the holes would correspond to the stock spindle but after i got it installed i had a total toe in of almost 2" .i was going to drive about 20 miles to check it out but quit afer 1/2 mile because it was real darty .thats the trouble with a gt body ,they are so curved i did not notice the excess toe in .after measuring ,i cranked out the tie rod ends 1/4" and now it works great .with the lowering spindles , i was able to raise the coilovers and get more travel .no more bottoming out on bumps and the shocks perform better since they are closer to mid travel .

just a bump to stay out of the archives .i was going to put the rest of my high performance goodies on before winter but i havent had time .i am going to put the parts (boost controller etc ) on over the winter now .i never made it down to the drag strip and that is disapointing to me but work (and the problems at the grand bend track with the new pavement ) got in the way of that .i leave the insurance on the car all winter so that i can do testing on days when there is no snow so at least i will be ready in the spring .things i hope to do : boost controller
install gear drive turbo oil scavenger pump
front tie rod replacement and whatever i need to fix on the steering rack
fix one axle boot
air to water intercooler install
hp tuners
swap out my drvers side seat fabric with the good ones i have had for two years now
figure out how to make the cavalier instrument lights work
and whatever else i can think of

thanks to everybody who has posted here . i will be back here as soon as the weather turns bad .

this is my favorite ecotec swap thread. I'm glad your setup continues to work for you. Keep up the good work man!

How much did you spend on your car to add the turbo to your eco? How much do you plan on spending for the H20 to air intercooler?

i think i added up to around 1400 as it sits on the car now .the air to water IC runs about 150.00 on ebay and i already have a pump so i will just need a small rad and a tank .i am hoping about 300.00 total .like most pay as you go fix ups ,i have lost control of my spending !

Cool man,
So are you going to keep your meth water injection as well as your new intercooler? So you can up the boost? *goes back though the thread to find out what kind of turbo and maniflold you used*

Where are you going to run your new coolant lines for the I/C?

Only $150? CDN or USD? Seems pretty inexpensive!

i was surprised how cheap they are .thats us money but the loonie is now worth more than a us dollar anyway ,i am going to use a tranny cooler for a rad.not sure where i am going to mount it but my ac does not work so i may put it where the condenser is .or i might just use the condenser and its lines , if i finally give up the idea of working ac .i also want a tank big enogh to put ice in at the drag strip . i am going to use both the IC and meth injection to try to crank the boost up to 14 psi or so .

So in theory, if you had just the A/W I/C, is it a question of how big your heat exchangers are at the intake and at the front of the car that determines how much boost you can crank into there? Will premium petrol help with the detonation? What about Ethanol? Ethanol technically is alcohol and alky is really high octane, isn't it? Wouldn't that make it more resistant to detonation? I guess availability is an issue there... plus longevity of the fuel system. Aren't some GM engines designed to run on E85 though? Can't wait to see your progress.

the boost is mostly limited by the actual strength of the engine components.on a stock 2.2 you have the rod issue ,head gasket ,and i found out recently that the stock piston ring land is another weak point .so i think 14 psi is max .
raising boost levels means more air is getting into the engine .this leans out the fuel mix and causes detonation .water meth and an intercooler help by lowering the air temp and by adding fuel .but at 8 psi with just the water meth i needed bigger injectors to completely eliminate detonation.to get up to14 psi boost the IC is going to help but more air =more fuel needed and thats where the 100 psi in line fuel pump and 6:1 vortech FMU come in .i already have everything i need except the IC .
i have not mentioned timing because the big plus with water meth is you dont have to retard the timing to prevent detonation .retarding the timing to control detonation also reduces HP and results in less complete combustion .
i would like the HP Tuners package to change a few things .lowering the injector duty cycle on start up to get rid of the occasional hot start flooding problem ,raise the the rev limit to 6800 so it wont be so easy to hit the rev limiter in 1st gear,and get more consistency in the AFR through out the rev range .

forgot to add : i only run premium .if the water meth runs out , then detonation is minimized .we dont have much choice in fuels around here .i like the 10 % ethanol blends because they dont have the manganese additive(nasty stuff ) ,but the only station that has it is ockward to get in and out of .
