ecotec swap (Page 33/98) wftb JUN 30, 06:30 PM the plastic pipe i am holding in my hand is the old elbow that connectected to my throttle body .it was a busy place and seemed a little restricted .so i bought a new silicone T fitting and a cast aluminum elbow and cleaned things up a bit .i also got my AEM guage type boost controller and hope to have it working this week .still have not made it down to the strip yet , work keeps getting in the way . wftb JUL 22, 10:28 PM all packed and ready for waterford hills track day on thursday : i painted my front scoop silver so it would blend in better : i hope to meet some of you at the 25th .i am only there thursday for the track day and overnight at the host hotel .leaving about noon on friday .have to work nights all weekend . wftb SEP 15, 06:38 PM i ordered a bunch of parts the other day .this winter i hope to ;relocate the turbo and use my solstice cat ,build a new centre console and new stereo , and a general cleanup of the wiring and engine bay plumbing .i will post some pics when the parts come in . Eau_Rouge OCT 05, 09:01 PM Wftb, I love everything about the ecotec and would love to put one in my car...preferably a 2.0 turbo (HHR, Solstice, Cobalt) but I don't want to run water/meth injection. I just want to run the engine and an intercooler - an air/water intercooler since an air to air just doesn't work too well in a fiero...I don't want to hack up my car. My question is, can an good air to water intercooler cool down the intake charge sufficiently such that the turbo can run it's 18 p.s.i - correct me if I'm wrong but the 2.0 litre turbo ecotec's produce 18 p.s.i. So is it possible to do this with an air/water or am I just dreaming? wftb OCT 05, 09:25 PM it is very much do able .but you will need hp tuners to set up the power enrichment tables to make up for the extra cooling the water meth provides .other things i have is a vortech 6:1 FMU , an air to air intercooler and bigger injectors .water meth injection is pretty easy to install and the tank can be mounted any where you have room .HPT is probably the easiest way to tune for a turbo ,especially with the wealth of info on their website . Eau_Rouge OCT 05, 10:18 PM What about running a small air to air where the cat sits on a v6 fiero in addition to the air to water...assuming that air can be pulled from under the car and into the intercooler? Is this possible, benefecial in any way? That being said, what about a second water to air in the place of the cat with a high volume water pump. Provided that enough air can be directed through the second intercooler, this should help reduce inlet temps. Any opinions? ...very nice build. I've enjoyed your write up and have learned a lot from it so keep up with the updates. For myself, my first choice is also the ecotec due to its low weight and power potential. Regarding yours, is tuned to your liking? How much hp is it producing? How's the power band? Is it linear? Does it produce a lot of lag...the last performance turbo car I drove was an 86 porsche 944 turbo and this thing was worse off the line than a bone stock 90's civic but at 3500 rpm the turbo spooled up and it put you into the back of the seat. Wasn't the greatest for a daily driver but sure was fun at the track...turbo cars are a lot of fun! Cheers! wftb OCT 05, 11:38 PM one air to water intercooler would be plenty .my air to air sits where the v6 cat used to be .an air to water intercooler is more efficient than an air to air , with less pressure drop .i dont have access to a dyno .rough estmates using my G tech indicate about 200 WHP running 8 psi boost .lag is only a problem if you are too lazy to downshift out of 5th gear at less than 60 mph .boost builds at 1800 rpm . thanks for checking out my thread . wftb OCT 20, 02:23 PM i have started my winter projects for this year .the first thing i decided to do was eliminate the cavalier ignition assembly .i no longer need it since i adapted the fiero ignition switch to turn on the engine and i useed HP tuners to disable the vats .to verify the vats was indeed no longer working , i disconnected the connector that joins the key assembly to the BCM .then i tried to start the car .engine started right up and runs normally so all is good there .next i took the cavalier ignition switch and disconnected it from the harness .then i checked with my ohmeter what wires need to be tied together to bypass the switch assembly .i found that with the switch on , all the large connector blades are common except the one for the starter solenoid .i made a harness to check my theory and hooked it up to the connectors and the car started up without the cavvy switch in the circuit .i now can get rid of two of the relays i have in place to allow me to leave the cavvy switch in the run position so i dont drain the battery .one was for the vats ,the other one turned out to be not needed any way as it enabled the key left in switch buzzer that i dont have .the other relay will stay in the circuit to disablepower to the ecotec circuitry when the key is off .as soon as i complete the wiring chages ,i will move on to this years turbo mods and interiour changes .i needed to finish the wiring first because i needed the engine operational to test everything . goodies just received from summit for turbo and exhaust mods . wftb OCT 20, 03:08 PM no more cavalier ignition switch and extra relays done away with : less stuff to hide under the centre console Fosgatecavy98 OCT 20, 07:58 PM How'd it run at Waterford? I got down to the 25th just on sat tho . Im still workin on the LE5/L61 hybrid issues. If I can get it tuned before snow flys, it WILL be running on E85 by april.
