I have heard it said by some people not to put in any engine bigger then a V-6 because there is no room for an efficient exhaust system. you won't realize any horsepower improvement anyway. The Internet can be very misleading - - -
Fits just fine. Exhaust dumps down and out the sides.
Super fun to drive. Very noticeable increase in performance. Going around corners is still better than a first gen mr2 but getting worse due to my aging suspension components - not the extra weight.
I love the 350 swap but a supercharged 3800 is still my favorite.

Those people just don't know what the hell they are talking about. And that' all I've got to say about that.

LOL!
I like your user name. I'd like to see pics of your Fiero that matches it.
Yeah, people and the internet can be soooooooo funny.

I am currently building a try-wy exhaust that I am hoping will look as nice as that last photo. I am about halfway finished and my pipes have no dents, in fact I even pounded a 1 3/4" steel ball through each pipe as I completed each portion.

Take everything you read on the idiotnet with a grain of salt, the size of my suburban !
People on the Idiotnet think they know everything, and then there are some who think they know everything about cars or things they have never even worked on like a Fiero. it's like those idiotnet reviews of products, they never bought themselves. I only listen to reviews from verified people who are shown to be verified purchasers.

I do not wish to open up the argument of which engine is best. That is a matter of personal choice and budget.. If you are looking for power and the best performance to date, all I can tell you is that the fastest Fiero on record is that of forum member Scott (Darkhorizon) and he runs the 1/4 mile in the nines. Scott runs a 3800 V6 with a single turbo and an auto trans. His video on the record breaking run is in a post on this forum. What is most remarkable is that the car is his daily driver!!!!

Welcome to the forum. Seems you have a lot to read. The best thing about the Fiero is that you can install a lot of different motors from GM or any other manufacturer. It all depends on how much $$ you want to spend and skills. Search in here and you will find them. From V8s to diesel, rotary, electric all have been done. Personally I think the most enjoyable are those in the 300hp/300lbs range for daily driver. But I have changed and no longer care for a 600hp or 9sec track cars. Pick your poison and if you can afford it then enjoy it
What transmission is dark horizon using? I imagine that his build must be quite expensive, maybe not. I personally enjoy having a lot of bottom end torque and I also use my car as a daily driver. My build is extremely reliable and inexpensive however I have broken three chains in my transmission in part because of the horse power delivery through my switch pitch torque converter.

First the Fiero was designed to put a V8 in when they designed it, they just never got the OK from the upper management to put one in so it will fit, quite nicely as seen by many of the 350 engines we have on here. they fit just fine.
now working on that engine after you put it in may be a problem but hey it will fit and will work just fine.
When I was a kid in the 60s we used to pull 6 Cylinders out of old Pontiacs, Fords and Chryslers and drop in whatever the biggest engine was we could find and they all ran just fine. Again the Fiero was designed from day one to put a V8 in.

He has a built 4t65e-HD. The 1" chain isn't available new any more though, but if you aren't running the 7/8" chain, I'd suggest upgrading to that if you're with the 4t65 as well.

My chain is like 3 inches wide, the 1 inch chain would be a downgrade.

I guess you have the 4t40 then? But there's more to strength than size. If you have the 4t40, then you should probably upgrade to a 4t65 or 4t80.
The 1" chain for the 4t65 was a GM Racing part, and was used 1000+ HP Ecotec drag cars on slicks. They were almost certainly making more torque than you are, and with greater shock loading on the parts.
Anyway, you asked what DH is running, and he has a 4t65e-HD that's been built to handle drag racing a Fiero with a 3800 making 900+ lbs-ft. If you want to make big torque and get it to the ground without breaking things, then you need the right parts, and you need to get out of the mentality of "it looks bigger so it must be stronger," because it is not not true.

So now I have done some digging around in these forums. The thread "from fiero to umbrella" The fastest Fiero is not dark horizon but rather fog from Finland He ran a 9.7 but has enough power to be well into the 8's. He has never broken this chain, same as mine. So do you think that fog and I should switch to a 1 inch chain? Like the 4t65 has???

What transmission are you using? Are you using the Tornado 325/425 trans? Or are you using the 4t60? So far, all I know is that you have a chain that you claim you break a lot. The stresses on the 325/425 which is longitudinal are very different from the stresses on a transverse setup like the 4t60/4t65/etc…
You asked what DH was running. I told you. The 1" chain isn't even available new any more. If you have the Tornado trans and keep breaking chains, then I guess you need to buy hardened chains or a different torque converter, or find out why else you are breaking chains. If Fog isn't breaking chains, I guess ask why he isn't. I don't know. I'm just telling you what DH is using, because I know, and you asked.

I am fairly confident "bigblockfieropacecar" is previous member "big block fiero" who had a 500 caddy with 425 longitudinal FWD transmission in an 84 pace car and lived in Minneapolis, MN. https://www.fiero.nl/forum/A...090219-1-062869.html
Before his departure, he was working on a low tech cylinder deactivation (his avatar pic), I would be curious how that ended up.

That was very successful, I won the Internet challenge that had been in five different forums since the early 1980s. (The first to complete a cylinder deactivation system on the 500 caddy.) That subject many thought easy to achieve but mine was the only one that ever succeeded. The secret was the relief bumps on the Cam base circles. That progressed into a Bolt on kit for the small block Chevy but died out for lack of interest.
Over the last 10 years I have never stopped designing, building, and wrenching as I'm sure most of you haven't either.
It's built for drag racing, not road racing. If you drag race a car all the time, an auto really is the better option.
I suppose you are right. But I never understood the appeal of drag racing either. Given enough power any level of acceleration is possible. By the time I finished 12 grade physics I was sufficiently convinced that F = Ma was correct and I didn't feel the need to prove it on a drag strip, but that's just my opinion.

And there in lies the problem.
2 cars "drag" racing each other was the first form of racing and will always be king.

You don't need to have sex to know how babies are made, but it doesn't mean the act itself can't be pleasurable.
Yes, we all know F=Ma well. But there's a whole lot more to the act than that simple formula, just like there is a lot more to having a baby, than simply having sex.

It's funny how people think the handling is terrible having a big motor in the back. I typically have been leaving my trunk lid removed which takes some weight off the back however I recently I was chasing a newish Camaro around several cloverleaves and turns and at considerable Speed. The guy found it useless to try to get away from me, I was easily glued to the back of his Bumper the whole time. I don't know how good of a driver he was but the point is the handling is better Than a regular car.
I'd like to see pics of your Fiero that matches it.
