Okay, quick and dirty, what is the difference between the 93-95 3.4 V6's and the 180-hp 3.4 liter that comes in the base model Impala circa 2003?

Thanks!! :thumbup:

Wrong. Impalas didn't have DOHCs.
the 180hp 3.4 is actually a 3400. Aluminum heads iron block.
Camarobird 3.4 is iron heads and block

Both are pushrod engines. Neither of them is DOHC.

Impala:
Better flowing lighter weight aluminium heads
Roller lifters
Correct starter location

Camaro
Same inferior iron heads as Fiero, making this more of a bolt-on affair
Flat tappets
Starter mounting holes must be drilled for Fiero application

the 3.4 in the newer cars is refered to as a 3400,

you can swap one into a fiero if that is what your asking, but they are alot more "modern" of an engine, as stated before, alum heads, better flowing intake, they also do not allow the use of a distributor due to the intake systems.

people have ran obd1 on them, but obd2 is the ecu of choice for most swappers..

60degreev6 has much much info on these.

the 3.4 pushrod(93-95 camaro/firebird) is a direct swap, only difference is the starter location which has to be drilled on other side of block. Uses fiero 2.8 acsesories, heads, intake,etc, and canrun on 2.8 fiero ecm. 3400 v6 is DOHC-swappable but much more work. Requires new ecm/harness, fabricated/altered mounts, custom exhaust, and it weighs around 600lbs and no fiero parts will bolt on except transmission.

Ahh ok so that makes sense, question #2 are these easy to turbo charge and how much harder is the swap if compared to the 93-95 Iron block V6's?

easyer then the 3800, they "bolt" right in, can use a 88 neutral balanced flywheel, and the stock fiero clutch, all the mounts can stay the same you may need to modify the front L mount bracket tho (just cut a small notch out to clear the diffret designed oilpan, takes 2min w/ a cutter, and no skill needed)

now the wiring is a bit more involved, depends on what ecu you wanted to go with... if you stick with obd2, you just need to flash it to get rid of things like passkey, then tie it into the fiero.. if your going obd1, youll need a custom chip...

then ofcourse theres exhaust and cooling lines...

oh, and to your turbo question, yes they love boost, how much is debateable.... but 300+hp is common on stock boosted 3400's.
