My large turbo fiero has better response than my trailblazer thats for damn sure....

I agree with FFIEROFRED. I have a small block Fiero that was my first Fiero and I assembled myself. I recently bought a 3.8 sc Fiero that was nicely done by the PO. After checking things out and changing a few minor things , I finally tried WOT. Well, it goes pretty good, and has lots of SC whine, making it sound to me like what I would think an electric car could sound under acceleration. It may be deceptivley quick, but I,m pretty sure my V8 car will leave it behind. I certainly agree that it will make a better daily driver type car and it does get a little better fuel mileage (23/20). The V8 makes more noise, is harder to drive, but when it comes to wow power, it's all V8. Nevertheless, I'm lucky to be able to experience both.

I have 3800 SC Series II and III, 383 V8, and 3.4 turbo engines in my cars. My favorite is still the 3800 SC Series III engine for performance and economy (MPG).

so now I'm stuck between the audi S4 twin turbo v6 motor because of the face it doesn't need any adapter plates for an audi trans or any special fly wheels or clutches however wiring will be a ***** and so will getting it to run right as far as throwing codes.....

or the L67 its a great motor all of the wiring diagrams are out there theres adapters for the motor to trans its reliable and i know the motor.......


what do you guys think between the two as far as better and cost?

been there done this lol

So would you recommend the 4.3?

If you go 4.3L it uses the same bellhousing pattern as the SBC which has the potential for far more horsepower. .

if you want Longitudinal then 4.3 due to the length and i am one that is going the road of longitudinal and be prepared to spend some money . the problem with the Chevy V8 is mated to the 01e is length to get the axle to not have to much angle you will need to move the firewall forward about 3 to 4 inch's or at least a section of the firewall as wide and tall as the engine.

stretch doesn't bother me I'm looking at 11 inches of stretch at the most and 5 at about the least . so no matter what way I go I'll have more than enough lenght.

if you are going to stretch it then SBC or LS V8 . go to Kennedy engineering or Advanced automotion for adapter plates

Engine man your doing the Audi v8 how are you doing the wiring any ideas yet?

yes i will have help from EFI Express they work on Audi and have VEMS stand alone ecu so it's just a matter of what wire needs to go where he also has the mapping for the Audi V8

Is tht v8 a drive by wire or cable? Do you know anything about the s4 v6?

it has a provision for a cable but i think they come through drive by wire

you can always run a 2002 S8 Audi engine 360 HP @7000 RPM they can be had for about $1500 to $3000 on car-parts.com

but what transaxel will handle that and is it drive by wire or cable?

If you want to drive it in 2013, go with a 3800SC. Drive it until the wheels fall off.

the 01e or 01x are more then strong enough according to Scott at Advanced automotion and can be built to handle like 700 ftlbs of torque i think he said http://www.advancedautomotion.com/

[This message has been edited by engine man (edited 11-22-2012).]

they are very pricey built that tough though, how does the 914 do? I was looking at the 01E and 01x FWD transmissions from a TDI but that was also quite pricey, I would love to buy one from a FWD TDI Car but they don't seem to have any in the states

the 016 is cheap it came in mid 80 to early 90's Audi and is the same as a 944 trans but with out limited slip but they need a strengthening plate not a big deal. I am using the 012 trans out of a VW passat and i am told it is not a strong trans and the 016 is stronger but i don't see how the 012 has bigger input shaft and same width gears

I was looking around today And I think maybe a Passat V6 won't be that bad as well as the passat transmission, theres tons you can do with the motors turbo, twin turbo, supercharger.......

and I'm ashamed to say I was also looking at the 1.8T parts from the passat. I had an 02 Jetta 1.8T until its sad death into a ford (wife ) with a 3 inch Turbo back Exhaust and it was a pretty fun little car

well if your going to buy a passat V6 just buy it engine & tranny together no sense to split them up then put them back together and you will be able to line up the axles no problem with room to spare !

thats what I was hoping not to need adapter plates or funkey pricey flywheels anything like that. But I am still looking at the stretched rear cradle fiero that Dave Held has for sale in the Mall section......

Bull. Both a straight 6 and a V12 sound way better than a V8.

I'd have to agree the Jag XJS v12 is one of the best sounding motors I've ever heard.

quote Originally posted by BillS: Bull. Both a straight 6 and a V12 sound way better than a V8.

More bull. It's a matter of taste.

So I've decided on using a whole passat drive train weather it be the 1.8t or the V6 for the simplicity of not having to get any adapter plates or expensive flywheels or clutches made up and that way I can justify buying a whole parts car for everything I need, the transmission will be a manual again for ease this way I don't have to worrie about any more wiring, however if I can get a wrecked automatic for a huge price difference I may rethink that, it depends on the fiero I end up with as well. I was thinking of not stretching the car and using the v6 if the Dave held car sells before I get assigned and situated into my new base, what do you guys think?

you can do a Audi ABZ 4.2 V8 they are 300 HP and weigh 375 LBS all dressed and i know that i have enough room for turbos if I want and the pistons , crank & rods are forged. oh and you can pick 1 up for under a grand

how long is that audi v8? is the 1.8 T the same length?

20 inches from the front of the crank pulley to the bellhousing flange

did that ever come FWD with a Standard trans?

not in the USA but 034 motorsports makes a flywheel insert $375 it is what i used and i used a 012 trans from a VW passat and the early Porsche boxster used this same transmission so you can use cable shift i bought my cables with linkage and brackets for under $100 all shipped to me

Lame, theres more money haha, I know this is going to be an expensive swap but I'm trying to keep costs as low as possible, I was hoping to get the Dave Held car with the 11 inch stretch and crazy tubular cradle, But if that doesn't happen I think I'm just going to get the regualr V6 5 speed passat and try to retrofit it on the stock fiero cradle maybe a few small suspension mods for a 84-87 cars and probably none for 88's. engine man Did you have to do anything crazy to get the v8 to fit or just make your own engine mounts? and dropped the fiero back ontop of it?

had to do new cross members on the cradle and engine mounts no big deal there

Ok guys I've been doing more thinking, and I'm still at a cross roads with either the 2.8 VW motor just because it seems like it will be easier to use a motor trans combo out of a wrecked vw passat so i don't have to get any special adapter plates or expensive work done to the flywheel, or to go with a 3.8 with an 01E out of an audi 5000.. its drive by cable, many many people have done 3.8 swaps so wiring diagrams can be had as well as help with running issues due to fuel lines/ delivery problems and things of that nature.


what do you guys think?

the vw/audi motor I could always turbo/twin turbo after I get it to run right.. the 2.8 is almost the same motor as the S4 twin turbo 2.7 v6 just less built up and better flowing heads/more aggressive cams
