ecotec swap (Page 45/98) wftb DEC 12, 11:21 PM thanks for the bump , fos .i have finally put the car away for the winter .the driving season this year was the longest ever for my fiero , first time ever driving in december .too bad it was such a cold summer around here .hardly ever got the boat out .great weather for golf ,except for the rain .got the car up on its dollies now .hope to start the roger thelin shift conversion soon and clean up the engine bay .have a great mod season and merry christmas everyone ! Austrian Import JAN 15, 04:21 PM Will you do a build thread update over the winter? wftb JAN 16, 11:33 PM i have not done much to the fiero so far , the car ran great all summer .i hope to clean up a few things .but i have decided to not do anything major this year .in the spring i am going to get it painted,and that will take up all my spare cash .i had plans to change my centre console and shift linkage and i have all the parts to do this, but i decided i like my cupholders better .i will try to get some pics up of thelins parts but i need to organize my photos first .in other words , the car is running so good that i no longer have that urge to try to constantly improve it . Neolithic Shadow JAN 17, 03:52 AM ive gone through your whole thread before and youve done awsome job, but i cant remember, are you running a wideband o2? wftb JAN 18, 12:30 AM i dont have a wideband O2 .i would like one , but since i have the HP tuners setup , i mostly tune based on the scans i take with it .there are limited changes you can make to the A/F ratio on the various tables .mostly i have tuned to avoid knock while keeping the timing as high as i can get away with .the water meth takes care of a lot of the knock and the ECM does the rest .i have a lot to learn about tuning but the car runs well as it sits now . coppertop_01 JAN 21, 01:05 PM Just read this whole thread, nice job on the Ecotec.....I actually just picked up a 2.0 Turbo ecotec before xmas and have been getting it ready to fab into the fiero subframe, but I am swapping the pistons and head to a supercharged 2.0 engine so I don't have to run the direct fuel injection system. I would suggest getting a wideband O2 system because tuning with HPtuners and the wideband works so much better, if you ever need a hand with tuning my friend tunes many cobalt SS's with lots of mods (he tuned my 2.0 SC meth injected 2.6" pulley ecotec DD). What temp difference are you noticing between your intake before and after the turbo? What temps are you hitting at WOT? Unlike you, I am going to run a air to air intercooler, not a water to air, I hope that I can get enough airflow to the intercooler to cool the charged air enough. Like you my car isn't going to have much of a trunk with the turbo, and since my chassis was rusty I already completely removed the whole thing, going to make things so much easier.

Keep up the awesome work Jer Where did you get your ecotec engine? I'd like to get an LSJ myself but can't seem to find anything for under $3k. Is that really the going rate - $3k? coppertop_01 JAN 22, 06:49 AM I bought my 2.0 turbo LNF for $350 as a parts motor with 17k on it, transmission came in at $500, and so far misc pieces/brackets/fuel rail/coil packs have cost another $500, they aren't cheap especailly the LSJ's and LNF's, but you can get a 2.2L base ecotec for significantly cheaper than the 2.0 variants........the only problems you run into is like wtfb when trying to boost an engine that was never wired for boost. Check the local cobalt/ion/pontiac boards (ontariocobaltclub.com, OPG, and to a lesser extent our6thplanet.com <-more into the S-series saturns than the ION's) , you can sometimes catch a break with locating an ecotec. Also check out the more national boards like IONforums.net or CobaltSS.net Jer wftb JAN 22, 07:37 PM hopefully , GM will put the 2.0 turbo into more cars and they will be plentiful one day .i have toyed with the idea of buying a cobalt ss , they are dropping in price but are not down to donor car status yet .when i can pick one up for 4000.00 or so i probably will . wftb JAN 22, 07:56 PM my intake temp at the charge pipe before the throttle body max out at 36* C .thats on a warm day . with air to air i was hitting over 42*C .the only thing i dont like with the water cooler is there seems to be a bit of a dead spot in 4TH gear when you hold the throttle wide open after downshifting from 5TH at hwy speeds .running up through the gears, WOT works fine .this is one of the things i need to look at in the spring .
