ecotec swap (Page 32/98) wftb MAR 11, 07:12 PM finished the wiring today and made a bracket to hold the ecotec fuse blocks .the inline fuel pump is now run off of a relaywhose coil is fed by the water meth controller .the fuel pump should kick in at about 5 psi of boost and drop back out at about 4 psi .this is because it will take about 9 volts to pull in the coil and at 8 volts the coil will not hold the contacts in .the point of all this extra stuff is so i can safelyrun at 12 lbs of boost . i ran at 8 lbs last summer with just the water meth and bigger injectors .this gave me an estimated 200 whp .i am hoping to pull around 250 whp this summer .the timing is stock and will probably stay that way . wftb MAR 12, 04:28 PM i got tired of trying to stuff everything under the old fiero centre glovebox so i built a new housing.gives me a place to mount the boost controller and boost guage . wftb MAR 16, 05:11 PM i tested my new auxilliary fuel pump controls by sending some air pressure in to the boost referance line for the water meth cotroller and the pump came on .works great.i couldnt test it by just running the revs up because my setup will not build boost unless it is under load .the roads are slowly getting better around here but i have some more front end work to do before a test drive.hoping april 2 after i get back from my florida golf trip . wftb MAR 20, 10:48 PM i was hoping to spend the whole day cleaning up some odd suspension jobs , but i crawled under the car to find that the turbo seals are leaking again .funny it just showed up now , i have been idling the car and checking for leaks of all kinds for the last 2 weeks and nothing at all till this morning .the culprit seems to be my expensive gear drive oil pump .there were 2 sizes to pick from and i picked the smaller one and that was a mistake .this pump just does not move enough oil .so i put the shurflo pump back on and even holding at a steady 3000 rpm , no oil past the seals .i dont really trust this pump , but everything i have read about it says they are reliable , so i guess i am stuck with it . i got around to the drivers side suspension .i needed to make sure that the poly bushings moved with the arms and not have the arms rotate around the poly bushings .this causes excesive wear onthe poly .i had to drill and tap some holes in the control arms and add some small bolts to get this the way i wanted .here are some pics: i also notched the poly to let the grease flow to the sleeve that the poly is supposed to rotate around .i wanted to get this all done before i go golfing in florida but i still have the passenger side to do .i hope to drop in on the daytona show while i am down thre but i will be sans fiero .and i have some friends to look up so who knows . wftb APR 07, 10:46 PM got back from florida (never made daytona ,no time this year ) and put the car on the road .tried out my HP tuners scanner and it revealed a big problem : thats my intake air temperature .when it wasnt in the red , it was between 35 to 42 * c .not good , even with water meth coolling .so i relocated my charge and intake pipes to below the car and found a spot where the filter could get outside air without getting wet (behind the passenger door ) .the result : now it is running at about 20* c and only spikes into the red under full boost .no more pipes over the engine : i used the hp tuners system to change my injector constant , calibrate my speedometer ,raise my redline and raise the speed governor .i am still getting the hang of hp tuners and have a lot to learn but so far i am impressed by this system . wftb APR 22, 11:51 PM the car has been running pretty good but every once in a while it runs like a 3 cylinder diesel that got into some bad fuel .this only lasts until you get on the highway and give it a good rev ving and then it goes back to normal .not knowing where to look , i thought it was the O2 sensors .replaced them , car ran the best it ever had .for about 40 minutes .then the the same thing .new o2 sensors are not cheap , especially when there is nothing wrong with your old ones .the real culprit seems to be my idle air control valve .this is not a cheap item either (200.00) .my engine and tranny cost me 1000 bucks .my two new sensors and one IAC valve cost almost 500 .00 .ouch ! performance improvements has a big sale on now so i bought an intercooler .sits where the fiero cat used to be : put some scoops on to lower intake and engine bay temps wftb APR 29, 05:02 PM in my quest to end my intermittent rough running , i figured the culprit might be my jury rigged injector harness .so i went to the wreckers and picked up a harness that had the right ends on it .it was from a v8 of some kind so now i have enough to make anothr harness .while i was there i picked up a working rt side headlight assembly to fix that problem .Huron Auto wreckers near Ripley Ont (519 395 2827) has an 84 4 speed that is mostly intact .body and mouldings look pretty good .it is red with grey interiour with striped seats .good centre consule and it has a sunroof ,drivers seat ripped but passenger side looks good .my harness: seems to have solved the problem but i only drove about 15 miles and sometimes i could go over 90 miles without a problem .either way ,it is a big improvement over the old harness .these connectors are nice in that they dont use the wire clips like the fiero injector connectors .they have built in plastic lockers on the side . wftb MAY 01, 02:02 PM my new injector harness has now officially solved my intermittant rough running problems .i put another 100 trouble free miles and there was no sign of problems and my hp tuners scan looks good .i should have fixed the harness first , would have saved some coin . i did some more tuning changing a few things to help lower my KR and improve driveability .got the data from a thread on the hp tuners forum .works really well , one more small change and all my KR will be gone .its amazing how little has to be changed to run a turbo with the stock VCM .if you ran a max of 5psi boost , you could probably just put 30 lb injectors in and carry on .the computer will lower your timing as the boost comes up and make other needed adjustments automatically. my car now runs like a stocker , except when i stomp on it .i didnt think i was ever going to be able to say that . wftb MAY 11, 09:49 PM the car is still running great and i drive it every day .hoping to get to the dragstrip in a couple of weeks .any one know of any dynoes in London , ontario ? wftb MAY 19, 08:39 PM i am waiting on a AEM guage type boost controller to take my car to the next level .a week from next friday i should be down at grand bend dragway to finally get an official time slip .(as long as test and tune is on that night ).
