Love the idea of putting the LS1 in the fiero. LSX in my personal opinion maybe not everyone elses is the best motor off the line I know there are arguments there but pls no post arguing otherwise b/c I know everyone has there own reasons and opinions. Been looking at putting a 5.3 in my v6 fbody (not tryign to hijack or anything) I'm new at the whole engine swap thing and don't know where to start. if anyone has any info msg me pls don't clutter up this guys post w/ replys to anything i have said just PM lol but like I said love the LS swap into the fiero

I got an answer about DOD and 5.3's
My motors are from a 2003 Avalanche (LM7), and two 2005 Silverado/Sierra pickups (L33). It looks like DOD came on a select few trucks according to the article below.
I found this on the Super Chevy website:
What GM Powertrain came up with--the 5.3L LH6--is almost identical to the outgoing LM7 on the surface, but technologically advanced on the inside. That technology enables cylinder deactivation (called displacement-on-demand or "DOD" by GM insiders) during periods of low load demand and is the source of the increased efficiency mentioned earlier. "We know that there are a couple of areas that we can attack to make an internal combustion engine more efficient," says Meagher. "These areas are mechanical efficiency, pumping losses, and unused heat energy. We knew that we could attack the area of pumping losses relatively easily with our displacement-on-demand system. That's the area this system addresses."
To an engineer, eight percent is a huge improvement. At the gas pump or on the dyno, it's also a huge improvement. "Displacement-on-demand is a win-win for drivers who rely on the power of the small-block V-8 and are conscious about fuel economy. The implications of this technology are tremendous," says Meagher. For now at least, those implications will be exclusive to three vehicles, the 2005 Chevy TrailBlazer EXT, the GMC Envoy XL and Envoy XUV. But before moving on to the nuts and bolts of DOD, we'd like to point out that it has far-reaching possibilities for performance enthusiasts. Had GM elected to apply DOD technology to performance vehicles such as the Corvette, GTO or a future Camaro, there would be far less pressure from corporate average fuel economy (CAFE) to import sub-compacts from outside GM as is the case now.

In my experience, the best values for 5.3L motors are the third generation LM7 iron and L33 aluminum blocks.

I actually do need a haircut , thanks for tip.
Ok back on topic :
What cylinder heads are the L33's running? What heads are you planning on running? GM castings or aftermarket? Are you going to leave the motor stock?

I think its funny you try to be clever, but can only cite 2 examples of v8 fieros that you think made/make more power then my old setup on a measly 4 cylinders. And its only 2 cars over a span of 20 years!!!! Bwahahahahha. **** bitch I was making more on 4 cylidners then you ever will with your 8. Not to mention more then the majority of pincocks members. So talk all the smack you want, but I called out 6-7 sbc v8 fiero owners here in the central florida area, and they all declined to run. BWahahahahaha. Typical big talk from teh v8 crowd, with absolutely no ***** to back it up.
Hey if im am totally done with the car in three years that would be a fine idea. I'm not making any definant finish date. Rushing things only leads to failure, but of course you already know that don't you. By the time i get done you will have gone through 3 or 4 engines and will not have learned a thing except what mid 13's feel like. Unless you actually use your little brain and ditch the 3.4-2.8 garbage.
Yea I might be out blowing up motor after motor, but at least I am driving it and having fun. What are you doing? Making throaty exhaust noises with your *** filled throat all while daydreaming of the day years down the road when you might get to fire up that sorry motor?
Yet I do know you have had your motor for 9 months or more, and don't have **** done to it yet. Hell it took you months just to get the pistons out of it. Not rushing things? You got that right. You have no money to budget for your build because you are a broke *** bitch. Took me 8 months from conception to reality to have it up and running, and 6 months of beating the hell out of a old crappy motor before she blew after making 300+ whp.
Yea it made more then 233 whp. Is it a record? No but its more then 99% of the members on pincocks poop palace with the almighty SBC v8 motor. Not to mention way more torque then cletus' famed 377 cubic inch torque monster witha whopping 280 whtq!! Explain that. Cletus has a hard time doing that with his 377 cubic inch iron bucket. Yet I am the moron for making way more then that, with less displacement and less cylinders?
I think its funny, you are carbing your ls4 motor. My god man what a waste. You really are a moron Dirt. I can see it now, you asking the morons on poopcocks how to tune your demon 650 carb, because you are puking black smoke, and don't want to have it dyno tuned, or get a wideband for it to do it yourself, because your fatass wife won't let you budget for it because she needs that extra box of King Dons tonight. She keeps complaining that her FUPA is getting smaller, and needs more honey bbq Slims Jims to puff it back up.
Go away Link, you have nothing more to say here. I hate it when Trolls try to think they can hang with me.

On another side-note, why the L67? They're quite heavy. As for your sig... there's a couple FWD W-bodies in the 9's with a transverse mount. With proper, and intelligent work on reinforcement, a RWD transverse can see faster times. But clearly, we're all here for max RWHP and nothing else matters.

LOL, youre saying Im trolling the thread when someone is carb bashing AS USUAL? L67s arent heavier than any other common swaps into fieros.
Yeah there are plenty of transverse set ups doing awesome numbers. Those trannys have to be rebuilt again and again. IIRC the fastest isnt a transverse set up. It does not matter because its a POS fiero. I wish I knew this many thousands of dollars ago.
Youre right, nothing else matters except WHP.

But all iron is a bad thing when you're trying to keep a car light. Iron, by its very nature, is heavy. The L67 is heavier than an LS1, it's heavier than the Ecotecs, it's heavier than a turbo 3400, and it's heavier than now even the LS2. And as anyone will tell you, the key to fast is not overall power output, but a power to weight ratio. You can have 1,000 horsepower, but if you weigh 20,000 pounds, you're not going to accelerate quickly in the least bit.
Example: Two 4th-generation Monte Carlos. One with an iron-block 350, one with an LS2. Both tuned to 500 wheel horsepower, and similar powerbands. The one with the LS2 will run roughly 1/10th of a second quicker down the 1/4 by nature of being almost 100 pounds lighter.
As for the transverse cars needing to be rebuilt constantly, they need not be rebuilt any more often than similar longitudinal setups. The Grand Prix that's running a TT3800 and in the low-9's, almost 8's (traction limited) needs to only rebuild after every season, and that's not a necessity, that's a preference on the owner's part. The T65HD is a much stronger transaxle than most people give it credit for, when in the hands of skilled builders. If the builder knows not what they're doing, then the transmission will fall apart like any other, by lack of knowledge and ability on the builder's part.
You're one of those people who live life 1/4 mile at a time, aren't you?
Man, I'm glad you weren't on the C6 Z06 development team.

Never said carb'd engines were bad. They're great for maximum power output on any application except turbocharged applications. But an all-iron engine with a carb in a car you're trying to build to be light for handling purposes is a bit counterproductive. There's a reason GM went away from iron construction and towards the aluminum LS1/2/3/6 and 7. But clearly, you know better than a whole team of engineers who have spent years perfecting this aluminum engine platform. They should just toss all that aluminum, fuel-injected crap out and go back to the carb'd, 500-pound iron engines once more. ![Icon Rolleyes](https://ls1tech.com/forums/images/smilies2/icon_rolleyes.gif)

Brutal...
your sig is soooo true...
20 yr old suspension ..hahah don't say that in certian fiero circles..the motor is in the middle ,it handles corners liek crazy!!! hahaha nevermind it's a citation rear end being fucked by a Chevette..
I love my Fiero , but damm some of the people who own them are mongoloids...
for all the money you spend modifying a fiero to be fast (and I am guilty of this)
you could buy a nice C5.. that was designed by real engineers...
Still have love for the Fiero...no love for the community though. (except realfierotech)
