i cut the bottom of the trunk off today .i left the part in front of the rear bumper as this wont interfere with anything .there is lots of room for the turbo and exhaust now .i am going to put a cross brace at the back of the trunk and then put sheet metal across to make a flat floor .the cross brace will be 'l' channel steel .this will give a place to hang exhaust brackets from.
BTW, the guys that make the Solstice headers are less than a half hours drive from me. I'm going to check them out this weekend if I get time. From the pictures, the headers ( and the Solstice exh manifolds for that matter ) look like they would dump out just above the differential if installed on a FWD or Fiero with Ecotec.
i made a cardboard template of the turbo's exhaust inlet and then put it up against the the ecotecs exhaust manifold outlet to see if they can be mated without an adapter plate,and the answer is yes.all i have to do is drill and tap 3 holes and the subaru turbo will bolt right on to the eco stock exhaust manifold ,thanks to the subaru's small three bolt inlet pattern.so the only adapter plate i will have to make will be for the exhaust outlet side .pics later today hopefully .
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 .
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.
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?
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.
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.
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.
i took the power steering pump off and covered it with a piece of 3/16 plate steel i cut to match the flange on the pump .used rtv for a gasket and bolted it on .there is almost no oil pressure here ,it just bleeds out enough to lube the pump bearing so the rtv(hitemp black) works well.
i also got the blowoff valve i am going to use .in the sumitt website it is listed as a vortech part .but it is a bosch part .this was the cheapest blow off valve i could find .when the pressure gets to high when you snap the throttle shut ,this valve will open and the pressure will get recirculated back to the pre turbo intake tube .the pressure that it blows off at seems to be controlled by a vacuum line that goes in to the top of the valve .not sure yet how i will hook that up .
the engine is running again and i have boost now.how much i dont know as i dont have a boost guage yet .i have to relocate the valve cover vent to the vacuum side of the intake as the valve cover was getting presureized by the turbo .so some more tubes to run.the plumber's nightmare so far :
Watch that ICM. Those things are sensative little buggers. There's a recall on the 03 and older units. They like to short out on ya and leave you stranded. Bad ground in several places on them. Might be why GM uses a dist on thier turbo race engine.
tonight i had a magor setback on my turbo project .the seals on my brand new tubocharger are leaking oil ! i dont know if they were bad from the start or if i had a blockage on my return line .it is supposedly under warranty so i will wait and see what the dealer says .so now the turbo is off again and work is halted .i thought buying a new turbo would avoid these problems.
i got the turbo to stop leaking oil today .turns out i had an obstruction in the oil return line .once i opened up the hole and put a bigger fitting on , it stopped leaking .the people that sold it to me told me it is designed to leak if oil return flow gets restricted. so today i am going to put on the exhaust .i would like to take it for a ride , but the roads are covered with salt and sand and slush .we are getting a thaw now after 5 weeks of almost daily snow .
the turbo still leaks a littl ,but just while it warms up.hopefully this wont ruin my cat converter .next time i will buy a genuine name brand turbo instead of a cheap knock off . the exhaust system is now complete and it sounds great and everything is nicely tucked up where the bottom of the trunk used to be .i have covered the hole in the trunk with some sheet metal.
since it has been so cold working in the garage these days,we are going to cancun mexico for some warming up .then i am going golfing in florida with my brothers and some friends .back in two weeks .

What airline are you flying on? I fly 3 Detroit - Cancun - Detroit (Sun, Mon, Tue) with USA 3000 Airlines. I have not looked on a map to see exactly where you are located in Canada. We get many Canadians that fly with us from Windsor.
He must be gone already. Oh well. He lives about halfway between Toronto and Detroit so I might see him tomorrow and never know it.

He needs to come back since hes the only guy here that can help me! lol i guess im on my own till fieroturbo or he comes back
well i am back .we flew westjet out of hamilton ontario .great little airport ,no need for shuttles and we got there 3 hours early .an hour early would have been more than enough.went to gran bahia principe coba resort in the mayan riviera near cancun mexico.then home and off to orlando fl to golf with 2 of my brothers and a friend.great trips .i need to go back to work for a rest. the oil return line still points slightly uphill and this is why it still leaks on startup.i tried twisting the turbo(it is joined together with a u channel strap) but then the air outlet hits the frame .i think i can take the oil outlet tube off and cut it shorter and this will give me more of a downhill slope and the problem should be solved .
