ecotec swap (Page 14/98) wftb JAN 16, 04:12 PM wftb JAN 16, 04:37 PM now that the turbo is bolted up ,the real work begins .and a lot of decisions .i found a lot of threads on turbocharging ecotecs on www. ecotecforum.com .the confusing part is what system to go with .i just spent two hours reading about the hptuners system.it sounds like the best bet ,but i am worried that i may still need other things to make it work properly.alternately ,i can go with a relatively simple mechanical fuel management system like an aeromotive #0271313107 (supposedly a bolt on)or similar vortech mechanical fmu .i am planning on controlling detonation with a water/methanol injection system .again a lot of choices and prices depending on method of control .i was looking at the snow units sold by sumitt racing.i am planning on running bigger injectors ,but a lot of posts tell me about problems with too big injectors , so i am going to try the stock injectors first and see how they work and then decide on upgrade size .this turbo will support 370 hp but my stock connecting rods have an upper limit of about 300 hp . so i am planning about a 10 psi max boost. hopefully that will yield about 200 hp and not too many driveability problems or the need for another fuel pump. anyway , back to figuring out the plumbing . wftb JAN 28, 10:00 PM everything is going fairly smoothly but the whole job is being held back while i wait for more parts to arrive.i want to fire this thing up but i still have not got the fitting to feed the oil to the turbo .apparently it will not be shipped til the 2nd of feb.lots of plumbing on turbo i have relocated the maf and vacuum signal to the fuel pressure regulator to the non boosted part of the intake system .i will need to add a check valve in between the valve coer and the airbox on the 5/8 tube that joins them so that i wont be pushing boost in to the valve cover. Fosgatecavy98 JAN 28, 10:24 PM Good luck with the turbo! Im MS stuff should be here this week, hopefully I can get started on that. Sometime I would like to get a count of us Ecotec swap guys. I know you fieroturbo, the guy that has a website (name escapes me right now) and me that are doing a swap. Is there anyone else you know of? BTW thanks for answering my q's! wftb JAN 28, 11:47 PM there is dejayee (i dont think i spelled it right) ,rodo with a really nice automatic and myself have running cars .there is another pff member besides fiero turbo who is also doing a turbo but he hasnt posted in a while .he is in the U.S. navy like fiero turbo and is away for long stretches.there is also kmunson's friend who is going to make and sell kits .there is a thread about it in the chat section .some really nice looking work ,and his car must be close to running. Fosgatecavy98 JAN 29, 03:41 PM Well I hope I can make the top ten at least. I got word that I ***should*** have my ecm stuff this week. I will be putting the adapter to the motor and mounting it in the car attached to the tranny but no flywheel or clutch. This way I can line it up and make the mounts for it. I hope I can have the motor running this by this time next month. To keep it on topic, is the MAP the sensor that the wires run with the fuel injector wires, just behind the TB? I found my airbox too, since I dont want to use that, do you think I will be ok with just putting a hole in the intake tube I am using ( its a CAI off my old cavailer)? Also do you still have the powersteering pump attached? I took mine off and need some sort of cover for it, I made one but its light sheet metal that I doubt would hold. Thanks WrenchingPilot JAN 30, 06:30 AM Hey Wtfb, Did the Cavalier axles swap right into the Fiero hubs?

I believe he used the fiero axles w/ the cavailer transmission, the axles are interchangeable from what I know wftb JAN 30, 05:15 PM the plug for themaf sensor comes out of the group of wires that goes to the ingnition module on the valve cover. wftb JAN 30, 05:32 PM i coudnt get a good picture of the sensor itself ,but all i did was take the grommett from the air box that holds the sensor in place and drilled a 5/8 hole in my new intake tube and the gromett will fit in the hole and the sensor pushes right in . the axles from any manual tranny fiero will fit right in to the cavalier 5 speed transmission.you just have to get the tranny located properly in the cradle and they are the right length .i used the cavalier rubber mounts and fabbed my own mounting steel that was welded to the fiero cradle .i found there is much less drivetrain shake compared to the fiero muonting system .the cavalier mounts seem to brace against each other better.there are pics at the start of the thread.
