They rebuild aluminum race heads all the time when something lets go. Try contacting a good race engine builder in your area and see if you can get a referral to a good head re-builder.

i didnt do anything to the car all winter .got lazy cause the car was running great and i have another project on the go .but now that i am driving the car again , some problems have come along that i had to fix .first i developed a leak between the turbo and the exhaust manifold .this was minor but caused the turbo to spool up slower than normal and was noisy till it warmed up .i did not use a gasket between these surfaces and that worked fine all last summer but some corrosion developed over the winter to cause the leak .so i made a steel adapter plate so i could use gaskets in between .seems to work well so far .the other thing that happened was that the bolt holding my homemade dogbone broke off at the thread line inside the threaded hole . so i welded up a new mount that now sits under the drive pully at the front of the motor .i incorporated an dogbone from my old 85 4 cyl .the rubber is too old and sloppy though , i am going to get a poly dog bone soon .but this mount incrporates a double shear mount so it wont have all the stress on one side of one bolt .after i tried it out , i added an angle brace to it to avoid flexing at the base of the post .i did not get a pic of the brace .pics:

the leak :

the fix:

what my exhaust system looks like out of the car:

i am planning on buying a proper turbo manifold but i want to get through this summer with this setup .i havent decided on the mfr yet so hopefully this fix will last for this season .

here is Roger Thelin's conversion kit for using the stock fiero shifter .i decided not to use it because i like my consule as is now and i was a little leary of doing the transaxle stuff .but the instructions are well written and it does look like a fairly straight foreward install .all the brackets and adapters are really well made :

i replaced my plastic BOV with a much better aluminum model by turbo xs .the old bosche was errattic and seemed to leak and was causing surging .cured the flat spot in my 4th gear downshift to pass scenario .looks better too .

Did you just hook the eyelet over the end and not actually secure it any way?
wftb AUG 07, 11:05 PM
that is the way i did it , the eyelet hooks on the throttle body wheel and has never come loose .this is a v6 throttle cable .4 cylinder cables will not work on an ecotec throttle body .

i went for a drive today .filled up the tank and bought a 2.5 gallon plastic gas can and filled it up and put it in the trunk .the object was to drive the car till it ran out of gas so i know how far i can get away with .i dont have a working gas gauge still , so i time my fill ups with my trip odometer .it seemed like a good plan but here it is 406 Km later and i still havent run out of gas yet .i have to work tomorrow and friday so my little experiment will end for now .dont want to have to jerry can it on the way to work, the comments would be never ending from everyone that sees me on the side of the road .

I did a calculation based on the reported fuel consumption for a cobalt ss taking into consideration the size of the fiero's fuel tank. If I recall correclty, you should see something north of 500km from a full tank of gas.
When you run out, please update...cheers.

havent been able to drive it enough this weekend to run out yet but i am at 450 km and still no signs of running out of gas......
