After seeing a thread in the OT area I remembered my and a friend a few years ago talking about doing a project fiero....like can you drop in an LS1 crate engine in there and make it fuckin crazy? He knew alot more about the car but he moved away so I dont know to much about it except for its very small, light weight, and can take some V8's.

his kit allows any GM small block to fit in there :thumb:

northstar motors are popular swaps for them

I've seen many Fieros with V8 swaps, some even with GM 4.3 V6s. The link PRD provided will be your best bet for a plug-and-play kit, but if you want to be different (as though a V8 Fiero isn't already) then you cuold go with a Northstar 4.0 or 4.6 V8. They're real popular with the MR2s, Beetles and dune buggies.

That website says that a SBC will fit right in without cutting or losing your accessories (like A/C) so that's gotta be your best bet. You can worry about suspension/tires/frame stiffening later on.

Another new option could be the LS4/4T65 in the GXP Grand Prix and Impala SS. They are down to 5.3 liters, but otherwise the same as an LS1. They do have a single serpentine belt for better fitment, and also a revised intake manifold. They were redesigned to fit it in a transverse setup - perfect for a Fiero.

If you want real cheap, then a carb'd SBC is yuor best bet. Extremely cheap parts and no electronics to fuss with - just 3 wires. The 4.0 Northstar (from the Olds Aurora) wuold be your next cheapest option.

I will say what I always say. Swapping a V8 into a light car isn't anything new or interesting IMHO.

The small block is a pretty tight fit but will work. You can also drop in a H.O. W41 Quad 4, 3.1L McLaren intercooled turbo V6, 3400/3500/3900 OHV V6, 3.4L 24V DOHC V6, Caddy OHV 4.9L V8, S/C 3800 V6, or even a Northstar. Pick almost any FWD GM powertrain and it will interchange into a Fiero. You'd mainly be limited by transaxle choices unless you drop the whole powertrain in. For 5-speeds you're essentially limited to a Getrag 282 unless you can find a 284 in good shape, or stick with a slushbox (125c/3T40, THM440-T4/4T60/4T60E/4T65E, or maybe a 4T80E).

Best bet if you want a V8 is the new LS4/4T65E combo. 303 horsepower, 323 torque, and simple bolt in without bell housing adapter plates, custom fabricated mounts, etc.


http://www.srtcentral.com/webfiles/misc/automotive/X11/Cars_front.jpg
BTW, you can thank the silver car in center for the Fiero's rear engine/cradle/suspension. And all engines listed above will also bolt into it as well (with exception of the North* (if you want A/C) and the 4T80E).

Click here (http://www.geocities.com/citation_x11/) and go to history. I like them better than Fiero's, although an '88 GT fastback with the revised suspension wouldn't be too bad. :thumb:

HOLYSHIT.....I always knew you could make them fast but I didnt know you can make them look good too. Some of those are just outright sick from the website prd posted! Man that would be crazy to have like 400-500whp in a car that small.....hmmmm Im actually considering taking on this project at a later date.

Any guess as to what the 1/4 time would be on one of those cars on that webiste or one with like 400-500whp.....its got to be real good?

they aren't as light as you'd think... if i remember correctly they weigh in at about 2800, but i'm not sure...

i really like those re-bodies they have... and the choptops with the lip and side skirts are sick as hell too :thumb:

the fake exotics are kinda gay, but those exclusive re-bodies look nice

but yea, 400-500 should be enough for 10's with good traction and driving :thumb:

oh yea... some of those kits are VERY nicely done...

i actually saw one guy that lengthened his fiero to make the wheel base match the ferrari testrarossa, and used mostly ferrarri OEM parts to make it... it was FUCKIN INSANE!!!! he was making all kinds of custom suspension and engine stuff on it... he was basically trying to build his own ferarri in all aspects ie speed, handling, looks, etc... and he was WELL on his way... VERY nicely done

The Archie kit only accommodates an SBC (GenI/II). It doesn't explicitly list the LS motor (GenIII/IV) so you can't be sure. But, they make many SBC-to-GenIII motor mount adapters, so you could either use them or with a combination of the Archie adapters.

That Fiero/Lambo is pretty slick!

Well thats good news that a LS1 Crate engine could fit in there.

That Lambo kit is just completely jaw dropping!!!! If that car drove by me I probably wouldnt know the difference....other then the sound of the engine/exhasut....but then again you can make a car sound like anything with full exhaust mods.

04-19-2017, 08:22 PM
Some random notes. The stock tranaxles in the Fiero were the 4-speed Muncie and an Isuzu 5-speed on the four banger 2.5L Iron Duke cars. The Muncie is actually stronger, but not as strong as the Getrag 282 used on the '86+ V6 cars. It also came with a 3-speed 125c automatic. The Getrag, slushbox, and the Muncie to an extent will hold up behind some bigger engines... as long as you don't have a ton of traction and launch them hard. Street tires and you might be fine, launch hard on slicks and the lifespan will drop.

The best models are the '88s which had a completely revised and much better suspension for the last year of production. Then GM killed the car. As usual.

They're actually a pretty safe car, with a strong space frame. They did pretty well in NHTSA testing.

Weight is something like 2600-2700 lbs depending on engine. Adding a V8 increases weight about ~200 lbs if you also swap to an automatic. With some higher rated springs they still handle fairly well. The Caddy 4.9L OHV (not the Northstar) actually has an aluminum block and weighs the exact same as the stock 2.8L V6.

A price of $200 may be great, but if its been sitting for a long time and you're in SoCal check on the non-op and registration. There could be some hidden killer fees trying to bring it back into service.

I'm not too big into the body kits trying to make them look like imports and other cars, but I have seen a few very clean conversion that look similar to a Corvette, but not like they were making an identical copy. Very nice look to them.

My favorite combo would have to be the Turbo 3.4 dohc v6 with a 5 speed. It's a completely custom kit but I have seen it done. I used to have a 93 z34 with just an auto and that fat pig was fun and comfortable. Had just a standard 3.4 in it. Man I loved that car.

My very first car was an 88' fiero 4 banger with a 5 speed, and my friend had an 85' or 86' 4 banger with a 5 speed. Not very fast, but it was a blast to drive. Gm built them like a tank. There was this one road i would take it down and launch it off of a small hill. On a good day at about 80mph I could get it airborn for a good 30-40 feet. I did it every day after I dropped my girlfriend off at home. The car never broke from it. BUt after repeated 5K rpm launches the half shaft stripped out, I replaced it 3 times, but even babying it they would go out in a months time, so I got rid of it.

the SC 3800 is a solid engine, lots of go fast parts for it. That 308 kit in the ebay link is clean too. As for the busa engine, I think its cool. If 300 hp or so isn't enough, there are lots of turbo kits for them. I think the record on a busa is 800hp right now. . . most kits are right at 300, so 600 hp is easy.

HMMMMM,

There isn't much known about the Ecotec tranny's because no one is making any real power yet. The 4L65 that Erica Nocita uses can handle the power but she's also got a bunch of money wrapped up in it.

04-24-2017, 09:56 AM
x2, or whatever will bolt in or there is a kit for. If it were me though, I would lean towards a SR20DET. Light, tons of parts, and the FWD trannies are good for around 400hp, and thats about all I would need. For drag I would go with the Supercharged 3800 and auto ala Grand Prix GTP, again with tons of parts, and there are guys with lots of power pushing that big ass boat down the 1/4, so the tranny should wotk well . . .

The choices for using a GM transaxle will depend on the engine you decide on and the application it was originally used in as to how well it should up. Some of the older J-body (Cavalier/Sunfire) used a transaxle that internally is the same as the Neon's old A578/T-350. The Ecotec has quite a few manual transaxles available, including some that have been used behind high powered Saab's. Then there's the older 4 and 5-speed manuals that most of the Fiero swaps use and a few looking into the newer Getrag F40 6-speed.

Most of the newer GM automatics are going to be electronically controlled, so you'd more than likely want to get a whole powertrain from a donor vehicle to avoid incompatibilities. A newer 4T65-E HD from an LS4 car would be the strongest that will physically fit, and there quite a few other ones that will also work.

Building a high powered 4-banger is going to cost quite a bit of money whether it's a Quad 4, Ecotec, a Super Duty 2.5, or a non-GM powertrain like the 4G63. You can buy something cheap to start with but it may cost a lot more in the long haul to get the power out of it that you're looking for.

poorwboy
04-24-2017, 07:15 PM
I m trying to find more info on the quad 4. But there isnt much on them. I heard of a guy making 400 whp with a turbo quad. The nice thing about a quad is you can get them dirt cheap. But parts are another thing.
