The Cat/exhaust is way too close the starters. Before you put that engine back in the car, cover the outer side of the starter with self-stick thermo shielding it will make it last longer.

I have used that exhaust wrap in the past. I didn't notice a temperature change, but I did not take any measurements. It stayed on well for about 2-3 years and then start to disintegrate. You should look into getting the exhaust ceramic coated.

Amazing thread man! You're inspiring me to pull apart my 2.8L and do some clean-up. It will be a while before I do any kind of engine swap in mine so it's nice to see a project I could work on in the mean time to breathe a little life into an old engine (227,000+ kms).

I don't think you need special valves for propane , i had a Chrysler that was working with gasoline and propane , don't think i had two sets of valves in there LOL, i could move to gasoline or propane and ( vice versa) just with a flip of a switch .
Also if it's cold over your place you will need a bypass on the heater hoses to get the coolant to heat the system or you gonna have problem with freezing .
When it is hot in summer it's ok but if you close the bypass in winter it will freeze the propane in the system leading to a stalled engine .
Don't ask me why , i decided to take the bypass and was trying to figure out why it was freezing .
Went to the place were they had installed the systemn and they found it right away .
At a garage they wanted to change the carburator , but was BO , Good thing cause the carb was modified to accept propane and gasoline .

as long as u stay in low RPM ranges its true that you can use propane on almost every gasolineengine.
Propane burns hotter than gasoline and in higher rpm there is not enough time for the valves to give the temperature to the valveseats.
Plus propane is much cleaner and burns much cleaner than normal fuel .
The lack of dirt in the mixture is also a problem. This dirt normally gets to the seats and the valves and fills the small holes there.
Here in germany we also drive a lil faster = higher rpm so its the safer way to use stainless steel valves and hardened valveseats ( ok i give a try without the hardenet seatrings first but i can upgrade later if nessecary ).

Chrysler for examply our 3.3l voyager minivan has already hardened seats + valves because this engine is bifuel ( E85 ( Bioethanol ) or gasoline ) ok now its trivalent .

Our Voyager is running on propane since 07 ( 60000km ) because of the pricedifference ( propane is less than half price here than regular fuel ) its a good way to drive big engines for less money.

ITS RUNNING
very smooth and on all cylinders.
Ive set the ignitiontiming it was ok .

but , my aftermarket instrument reads 0 oilpressure it started with 4-9 psi but after 1 min it went down to zero ....
tomorrow i guess ill swap in another pressure sensor and test with a akkudrill if the gauge is reading something.
I guess ill check the valvelash too .


hmmm

Looks like your tach filter is mounted on the wrong bolt... I belive it is supposed to go on the other coil bolt, away from the exhaust maniflod...

What is that hose attached to your crossover pipe shield?

Thought that old hose was some sort of cooling device for your exhaust

I am sure you can find ANY information needed from others in here (PFF). Some of these guys know the Fiero inside & out and could probably assemble one in the dark...

Update:

changed oil alrdy after first 100mls and engine is running very well.
I setup the timing for the first 1000mls conservative at exactly 10°

I still need to install the propanesystem , a new 200cell racing cat and an electrical coolant heater with 220v plug for cold nights.

Oilpressure is fine , i had a ground problem .
After adding some extra ground straps the gauge shows the exact pressure.

After the break in period and the install of the propanesystem ill guess ill go to 13°-14° ignition advance .

Iam planning an dynoday next year if i get enough ppl to join

I realize you have the Y pipe wrapped and installed, but, I just noticed the Y does not appear ported. Did I miss something?

If it isn't ported it's a real good idea. Just wondering

Engine has now 2000 miles on the clock and it runs great .
Next week i can install my new propane systeme , took longer till my dealer got the system.
Magnaflow 200 Cell Stainless steel cat is installed and i got no problems with it on emissions testing.

Have atm a lil problem with steering stability everything is now new on my suspension ( all poly + konis ) all new balljoints but still play in steering
Had also a computer 4 wheel allignment .
ok long talk short consequence : more then 100 mph is not good atm but car goes very quick to the 100

Very nice build I have done quite a few back yard builds and never had a failure. I just did the 4 cyl to 6 conversion and on the drivers side i cut the steel tube and double clamped the V6 hose to the tube. I was going to swap it for the correct tube till I realised the whole LF suspension has to come off what a pita. Did you assemble the motor in your apartment or basement? Some of the flamers are the start are your typical more is better people. They must not have had the satisfaction of handling every piece of metal that is in there motors tightening every bolt and putting some real love into a project. It took me 11 years to finally have a fiero i can drive after buying my first one ten years ago. Congrats on a great build sometimes its not the bragging rights when you blast everything away in sight but the smile on your face everytime you turn the key and it fires right up that makes it worth the time I know I am still smiling

If i remember correct that kit was from a local us car parts dealser here in germany www.kts.de or www.us-parts-online.de

I also refreshed an CS Type Alternator and had it documented
http://www.format-service.de/tips_20.htm

update on the car :

- 4200 miles now
- did a finetune 4 Wheel allignement myself using two laser equipped digital spirit levels
now car is stabil like a rock even at higher speeds .
hat it over 120 mph alrdy but regarding the bad and snowy weather here its not wise running faster atm.
- front exhaust manifold cracked now 3rd time so i guess ill start building me a new one
- iam with this engine at 26.5 mpg ( per us gallon ) / 31.33 mpg ( uk gallon )sometimes lil more
- german Tüv guy keeps telling me that the car is way to loud so i guess i refit the waterseperator / helmholzresonator i removed vs a straight pvc pipe

Yeah. Excellent writeup. You must be a teacher. I just browsed through your alternater link. Even though I do not know how to speak German, I was able to tell what you were doing by the detailed pics.

Nice to see that you are able to put a few miles on her. I know that you have put forth a lot of time and effort to get it to the stage she is in now. Very nice job.

my front manifold was after some weldings so out of line and cracked again so i decided to make a emergency manifold by cutting a rear manifold and weld it together to a front manifold.





too bad that my new welder has big problems with the wiretransport aaaaaand
my weldingskills in electrowelding suck very bad. in fact thats my 3rd time ever i welded electric.
So dont judge me









and it fits like a charm



ok still there is the missing bolt on cylinder 6 but ill fix it next weekend

there is my new sequential LPG system
its a lot more sophisticated than the old venturisystem i had before.
It has a lot of own Sensors even a own MAP Sensor that registers positive and negative pressure
then gas temp , coolant temp , air temp and and and .
With this system the fiero has now a real sequential injection and not the ugly batchfiring .
i take the signal of injector 1 and 2 then the system knows when to fire the other injectors .
That should get me a much better mpg



btw engine has now 5700 mls on the clock and its running strong
and it passed all technical inspections
