thanks for the link dennis .i like roger's stuff .my next eco swap will use his shifter kit.i prefer to make my own mounts though .fosgatecavy is making a megasquirt based engine management complete harness and is taking orders now for this product .so , really all the hard stuff can already be bought rather than made up like i did .so i dont think this is that difficult a swap any more .and when i did mine it just didnt seem that hard .i had it running in 6 weeks .i like to think of the fiero as more of a rolling chassis than a complete car .so when i got the entire wiring harness from the cavalier and saw how plug and play everything was , it was a piece of cake to get the car running .i dont believe in getting everything done at once .i like to make the improvements as i go so that the car can be driven more often than not .in the summer i dont do any job that i cant complete in less than a weekend .
it would be nice if roger thelin would do a build thread .i would like to see what he did for wiring . |

My idea of a Ecotec swap would be one that utilized the stock PCM. I'm not sure how that PCM functions or what the magic is to solving the interface issues but there is aftermarket support for it. I'm sure that you can use a Megasquirt for engine management but you'd have to build all the tables like the VE, AE, MAF, PE from scratch. GM has already done this so if the GM PCM could be suitably trimmed to disable all of the un-necessary functions it should work fine. Don't know if anyone has done this as yet. How is your powertrain management working out? ------------------

i use the ecm and bcm and all the wiring from the cavalier that my engine and tranny came from .i also have the cavvy fuel pump assembly .i just got rid of the light harness and anything i figured i wouldnt need .i have HP tuners to setup my turbo and get rid of vats .my car runs like it came from the factory , because the electronics running it did come from the factory .but with megasquirt , it would be easier to utilize the stock fiero guages .i use a cavalier guage cluster .

now that i have my changes to the interiour all finished for this year , i am moving on to the front end .the bearing cap fell off of my drivers side front wheel hub sometime during the summer .it caused a slight rattle that i couldnt figure out till i took the wheel off and found the cap sitting in the centre of the wheel .it looked like the wheel sealed everything enough to keep water and crap out but i took it apart to be sure .nothing got inside so i just added a bit of grease and put it back together .but it got me thinking about nicer rotors .there was a thread started about using evo rotors but i am not having much luck finding it .but i took some measurements of my street dreams spindle and hub setup :
centre of hub diameter : 2.40 " stock : 2.28 "
hub overall diameter : 5.25 " 5.48 " with ridge cut off , mine still have a ridge
spindle to hub face : 3.16 " 3.34 "
stock cut down firo spindles :
i dont want bigger rotors (currently 11") . i can stop like a porsche already and i dont want to add unsprung weight .i might try to adapt some wilwood 4 piston calipers .making a mounting braket looks pretty simple .in the meantime if any one knows of any modern cars that use the 5X100 bolt pattern let me know so i can see if they will fit .

A bunch of German cars. Ask BMWguru. 
Few I know of: Audi TT, VW Jetta, VW Golf, VW Eos (BMWguru would know the rest of them, and the various rotor/caliper sizes)
I think either the Subaru, or the Mitsu Evolution have a 5x100 bolt pattern as well.
Scion Tc I think has a 5x100 bolt pattern as well.

i have found quite a few that have the right bolt pattern ,but most of the sites dont list the specs i need before i order .so i found some EBC lebaron rotors (early 90's ) at summit racing part # GD 7217 .these look to be the same as what i have but they are plated and dimpled and slotted .so a big improvement .153.00 for the pair .also for a nice caliper upgrade stainless steel brakes SSB A181 for 409.95 with pads and new bolts .also even nicer powder coated for 519.95 .sot of waffling on this purchase , as what i have now works great .thanks for all the replies .

i went and bought a stock 93 lebaron rotor and the specs listed on the summit part # do not match the actual rotor .the stock rotor is only 10.25 dia and has 1/4" less offset .other than that it fits perfect ,but i dont want a smaller rotor and i dont want to shim my caliper .so back to the web i go .EBC GD 7217 will not work .

after investigating further , i found out that chrysler put up to three different sizes of discs on the same vehicle , depending on stock rim size .so i think i have found some that will work.the discs i have now are 11" vented rear discs off one of the lebaron models .i found a part #but no demensions .i am going to adapt a front rotor , wrong offset but i have room to move the bracket .

found these wagner rotors at canadian tire :
they have 1/4" less offset so i had to do some more shimming .but they fit far better than my old roters and because they dont have the parking brake drum they weigh 1.5 lbs less .the centre hole only had to be honed out .003" . my hone that i made from an old cylinder hone:
i painted the new rotors with black high heat paint .the swept area wears off in about a hundred feet of driving and the rest then stays rust free .
i am going to stick with my old calipers for now .here is the old rotor :
the new rotors have much better runout and the pads are centred better on the disc .with the old rotors the pads have developed a ridge .i am getting new pads tomorrow .

just wanted to warn everybody that the wagner discs in my post above do not fit the cut down fiero hubs .the centre hole on the disc is too big .they fit my street dreams spindles just right .got the other side on and installed new pads today .
