Awesome write-up! I'd give you a plus but I don't have enough posts yet
For parts cleaning, have you just been using gasoline or have you been using any other commercial cleaners? I have NEVER seen a motor that NASTY on the inside before but you're getting it all nice and shiny again
Edit: And is there where I say something about owning this page? :P

ok i was unhappy with the heads i alrdy did because of the "old" valves and too much play in the valveguides so i decided to order the stainless valve kit from TFS and startoverwith a fresh ugly head set
the new valves and roller tip rockers
my 2nd head set
summary :
still to do : - porting the 2.nd head set - refreshing the engine wiring harness - building me a set of vacuum lines - overhaul a EGR Solenoid - building or buying a egr tube - lil cosmetic work for the upper intake - getting fresh engine mounts - rebuilding the alternator - and of course put all the stuff together in correct order
I hate to admit but i've worked with motors that looked as bad as this did when you started. Now that i'm older, i look at this 2.8 and think, I would rather have stuffed bamboo under my nails then to redo this. My hat's off to you for your drive and enthusiasm in making it all work and work corecctly. very nice writeup and i'm def giving a plus to you for outstanding photography. I hope when you put that puppy in it runs like a well oiled machine. keep us posted and keep the pics coming.
we did the .030 over speed pro pistons, 3.1 crank and a crane cam. the car runs great, my son gets an avg. 24mpg city /hiway. it has only run a 15.40@88mph in the quarter. it runs really strong in the 2000- 4500 rpm range but dies out after. i am starting to think that most of the people on this forum are right about the intake possibly restricting this engine. we have done the y - pipe mod, no cat and an ocelot exhaust. like i said the car runs fantastic to a point, but it feels like it has so much more potential. it is a 5 spd.it has been my son's daily driver for the last 5 yrs, relatively maintenance free. he has raced at the track against other cars and it will stay with a lot of other cars until it gets into the higher revs. it is an absolute rocket in the mid range kind of like the old tuned port injected v-8s in the 80's camaros and firebirds. not sure what else to do to improve the performance without spending a ton of money. at least until we finish his 3800 88 formula/5spd.
and a wooden testcylinder with the wanted size for the exhaust channel to test if the size of the exhaust channel is the same all the way down to the valve
then a absolute must have is safety glasses + dust mask i already hat a metalpiece in my eye when i forgot to wear the glasses , it took almost a week till the infection was gone ..... and without dustmask u get all the fine dust in your lungs which is also no pleasure.
porting with cleaning and polishing took me 2 days per head but i think its possible in 1 day with more time per day and better tools
Please continue to post I really like what you are doing, One of my dreams is to one day rebuild an engine, seeing what your doing gives me motivation.
mounted a new harmonic balancer from the Fierostore , but 2 of its holes has another thread than the others .... i dont want to use only 2 bolts to mount the pulley ....... strange
started with the upper intake , polishing it a lil
(I think I may go 3.1 with my Fiero one day - same problem in France as you have in Germany --> engine swaps are a big no no, except if you swap in the very same type of engine !)
could you tell me what diameter and type of pipe you used for the vacuum lines? I am not near my car at the moment but i am preparing to change out old parts and this would help me no end.
Just one thing fieromaniac, why didn't you use gaskets for the upper manifolds?? The blue silocon could of been prevented.
Nice rebuild though...
I need to take down upper and middle intake again when iam installing the Propane Injectors with the silicon iam not wasting a gasket . The Propane system will be installed after the swap because i want to minimize possible sources for errors.

thanks in advance

3 or 4 mm in diameter for the small tubes ( dunno what i took , i had an old vaccumline with me and compared the size in the shop ) then a 6 mm line and a big 10mm
Standard copper pipes , i guess for gas installations i saw them in hospitals for oxigen .
Timingcover,heads and all bigger parts went in my bathroom . I tanked the parts and used some bathroomcleaners to get rid of the oil. (tried also pipe cleaners but they are to agressive for aluminium)
smaller parts like the throttlebody went in a bath with bioethanol(E85) + lil mechanical cleaning with a brush
