V6 Engine Rebuild -mild performance- maniac way (Page 17/18)

Hey, Fieromaniac!

This has been a great thread.

Are you going with liquid propane injection? That ought to give you a really cold and dense air/fuel charge to the cylinders. It'll be interesting to see how you tune for that high octane fuel and how the performance of the engine changes.

Cheers

Edit to add I own page 5!

because of several glitches i decided , that this engine will get a normal sequential propane system and not the LPI system.
1. there is no datasheet for emissionvalues for the Fiero and without it i could drop in emmissionclass to a more expensive level (taxes )
2. LPI Injectors have to be very next to the intake valves with the normal injectors i have a hose coming of the injectorblock that goes to a small port i can drill into the lower manifold for each cylinder.
with standard fiero intakemanifolds there is simply not enough space .

3. LPI systems require an propane pump that pumps the liquid propane to the injectors and ive a lil "spaceissue " in the Fiero trunk.

our propane buthane mixture is rated at 116 octane so i guess ill set my ignition timing to 14degree for first testing.
I also add a exhaust temperature gauge to see what "window" is possible .

my buddys formula will get an 3800 na engine and i guess that is a very good candidate for the lpi system.
I guess ill start a 3800 rebuild thread soon

started with the install of the new LPG System.
of course i checked the valvelash too .



drilled the LPG ports in the middle manifold













good place for the evaporator and the ECU





setting the injectors to the engine size



injectorrails attached



injectorharness needs some extra cables







further installs







LPG Hoses + Filters



LPG systems MAP Sensor is attached

Your engine is beautiful. But with all that detail, why didn't you paint the block and heads?

New Project :

3800 N/A out of an 90-92 Transsport L27 i guess.
a friend of mine bought it with 2* 4T60E for 150 Euros

plans : several variants possible
- staying with a stock N/A
- turbo it .
- supercharge it
- stay as an N/A but with 9.5 piston 1.8 Rockers , perf. crank and some more goodies

here it comes







opened it up and it looks surprisingly well , in fact the heads , lifters and rockers look brand new





waterpump looks new to me too



buuuut heres the 1st thing : no gaskets unter the lower intakemanifold to the heads and keep tight on ur seats they mounted the Head without
a Headgasket . And for sure this engine was running for a while .



several years water in the cylinders cant be good



cleaned it a lil





rust



new freezeplugs and take a look to the teeth of the flexplate its also brand new



opened the bottom to pull the pistons and check the bearings











crank is very good but all bearings have to be new .


stay tuned . soon to be more

Update :

the 3.2 V6 engine from the begin of this thread has now 12000mls on the clock and its running very well on LPG.
Iam installing an Oilcooler atm .

Update II :

got a used 3800SC from the canadian PFF member 1fastlatino
now ill start making a engine out of both because several parts of the N/A are in better shape .
Ill post some pics later.

@fierosound :

i could use a GM Powerbook for the 3800 90° engines if there is one .
