Love the Fiero content! I've got an '85 that is waiting to get the Duke pulled out. I'd like to start with a full rebuild just to honor it, *should* be good for ~130hp... end goal is the 3800 SC. Your videos do such a great job explaining your setup, and I'm sure I'll have to rewatch in a few years! Thanks!
I loved my Fiero back in the day …I bought it brand new in 85 …. But now I guess you could say that my Corvette C8 is the modern version of it and I love it ❤️ …. Your knowledge and attention to detail is wonderful to watch . Keep up with the great content 👍🏻
Depending on your 'daring' level (IF it's street driven!), if you want an easy weight saving, take your door skins off and remove the crash bars. They're about 50-60% the total of the door! Not kidding. It's incredible how heavy they are.
Oh, and pull all the carpets. And sound deadening material from under the dash, under the carpets, and up behind the seat. Coupled with the above post, there's your 200lbs right there!
9:22 lol @ pop the headlights out to slow down. i have a 2007 grand prix gt with a built ~400hp 3800s/c and i'm always keeping my eyes open for a fiero project. nice job.
I'm in the process of building a turbocharged version... 👍🏽 Your videos have been very helpful thank you! Ever check out Richard Holdener's series on the 3800? Very informative.
I had a GT & always wanted to put a V8 or SC 3800 in it! Now you’re giving me motivation to buy another & race my brother in his. C8😂 Also how much do you charge to install the SC 3800? Nice race too with the C8..! Just a few more tweaks and you’ll beat the next one.
You have done what I always wanted to do.There is a 88 GT that I put away over 15 years ago.Been thinking about reviving it.Would like to pick your brain on the swap to 3800 huffer power.
Everything you need is well documented on pennocksfieroforum.com. Search their archives - this is a swap that has a lot of good writeups so you can do what fits your preference the best.
@Toys4Life Thanks man got the gears grinding on it.Almost time for a new project I've got my 65 Dart GT 273 4bbl on the road and have room in the shop.I like a broad spectrum of vehicles.
I would not because you will be tempted to boost it to higher HP/Torque levels than the transmission can handle. Many of the 4t65e-hd trans performance hard parts are not longer available or cost $$$$$ used. Just my opinon.
In retrospect I think I should have done a 3.8 SC automatic. I love the SC sound, it’s fantastic but I love the V8 sound more so that’s the way I went many years ago. The A/C compressor setup ain’t great on mine with very little wrap (not that it matters, I haven’t fixed the Freon leak behind the compressor in many years.) if I had the time and the money I think I’d swap it back to the 3.8 SC just for its much more simple setup. Oh well, maybe when I retire in a long time 😂 or my kids get older. I bet I could at least break even on the swap with my V8 being a hopped up ZZ4 with full roller rockers and LT4 HOT cam…I could probably get decent money for it.
@@Toys4Life for sure. They were a pretty decent amount when I was in college in the late 90’s, but nowadays months ago by and I don’t see one. I will tell you one thing, the V8 sound turns A LOT heads and gets a lot of questions whenever I stop for gas or anywhere for that matter.
90s Fieros V8 swap was king. 10's Fieros 38SC was king. Will definitely be 4 bangers going forward as the top engines are all 4s now. Heck even some exotics are 4 bangers. Light turbo 4s are taking the crown for fuel and power and handling
Try working on a freaking Subaru, I've worked on both. I'll take the fiero any day. No the Tahoe made in 2008 has a ton of room, but it's also got about 13 modules.. I hear Lamborghinis are easy. My point is not to be a jerk, I think it's all kind of relative don't you think?
Find that hard to believe. I frequently go junkyard hunting (mainly Fieros but like to walk the yard and pull other similar era parts at times. Compared to others 80/90s cars, there is a ton more room in the engine compartment. Heck some of the GM V8slike the vette required half the spark plugs be removed from under the car.
4t65e-hd with just a basic rebuild of known weak parts. It has held up for 8 years now and hundreds and hundreds of pulls. I am surprised 1-2 isn't going out actually!
OK it's finally been answered.. I thought it was the 3.8L V6 which was a lot more powerful than the 2.8L they were putting in them.. There was a guy local to me back in the day who had a turbo'ed 2.8L GT Fiero and that thing really moved out.. In 1989 he was beating all the Vetts around tracks with no problem once he turbo'ed it.. I think it was a 5 speed manual.. But it was fast..
You have a very interesting, well thought out Fiero. Well done. How hard was it so shoehorn the Buick 3.8 litre engine into a Fiero? What kind of brand, type and viscosity of oil and transmission fluid are you using in it?
Since the 2.8 V6 that came with these as well had such a wide intake manifold, the 3.8 actually fits better IMO and all 6 spark plugs are even easier to change!
Hi, I’m a big fan of the channel. I’m having some problems with my 3800. I don’t know where one day it just started.Hunting at idle I’ve thrown the parts canon at it and changed all sensors with no luck. My efr looks like a pendulum. Have you had any issues like this?
No codes. I feel like I hear a lot of chatter on the top of the motor. I put a new sc coupler in when I did the motor. I would love to send you a video
I'm not sure but the turbo guys break them often and a lot of times all they can get are aftermarket replacements which aren't as strong as the original GM stuff was so it probably depends on if you've got an original GM axle components or aftermarket Chinese junk. Mine have lasted for years but I'm underneath there fracture limits apparently.
The atmosphere supplies about 14.7 psi of air pressure. It's not boost technically, but it's still pressure and that's why cars are a lot slower in Denver than they are and Florida at the same temperature of course.
@@Toys4Life atmospheric pressure doesn’t register on a gauge though. What your talking about is O2 air density that’s the reason why you need boost to make same power at higher elevations. Just like how it’s harder for us to breath the higher you go the less O2 is in the ambient air so it requires more total volume to get same O2.
@Thumper68 I believe atmospheric pressure and barometric pressure are the same thing., barometric pressure measures your air pressure and You can convert it to PSI if you want. Denver is at like 12.4 #psi and Florida's like 14.7 so the air is denser with the higher pressure as they're directly related and therefore every breath of air in Florida contains more oxygen. I'm not sure what you're getting at.
@@Toys4Life I’m just saying that oxygen density in the air changes with the elevation and that’s why it’s harder to make power at elevation. We like to think of our engines needing air,fuel,spark to run but it’s really oxygen in the air that’s important. For open fire to burn you need like 16% O2 minimum obviously not the same as combustion in an engine but just for reference. The air we normally breath is around 21% at sea level the effective amount of O2 in aspen colorado is 15.4%. So the get the same amount of O2 in the engine that’s why we need boost. I mean technically the same amount of O2 is in the air it’s just not as dense or as you said as much pressure. I just hate referring to it as pressure because to our engines it’s not measurable as pressure so using density is better terminology imo.
