Cool engine swap. :cool2:
Its an Invasion 4.9, 5spd Stick Fiero
OK quick intro.
Pics and short video's can be found at http://www.captfiero.com/cadero
Car is an 85GT with a 5spd Stick, Centerforce Clutch, 4.9 from a 93 Elderodo dual O2 setup. Using a custom Chip with the "Fast Chips" fuel and timing maps.
Car setup is like I said an 85GT Fiero.:bouncy:
Mid Engine, transverse mount rear wheel drive, 4 wheel disk brakes, 4 wheel independent suspension, 245/50/16's in the back and 225/50/16's in the front.
I have got a bunch of rather unique issues that hopefully ya all can help me sort out.
First off The old stock O2 sensors were old so I bought a pair of brand new NTK O2 sensors with the correct plugs. Well as soon as I got them in I noticed that on the scan tool, the voltage on the O2's are pretty much flat at 444mv the cross counts are down to like 2-6. They are located about 5" from the manifolds so location should not be a problem. The exhaust on my car is rather short. It is approximately 36"s yes 3ft from the down pipe to the Tip where it exits. The car will drop back into open loop at idle which is strange but I am told it is not un-common. What do you guys recomend for good O2 sensors.:thumbsup:
I have had a hell of an issue with the idle down procedure. It does not want to drop to idle until I am below 5-10mph. Which is really annoying especially when I am out cruising along in 5th and the car wants to cruise along without me touching the gas. Anyone got any good tips.
It looks like many of you guys swap out the OEM injectors for the Mustang ones. Which I just happen to have because it is also a common swap in the Fiero's. I have a set of perfect 19# orange top injectors kicking around. Is there any real benefit to using them.
Oh I could go on for a while with other odd questions about swapping the Allante intake and the Delta Hot Cam for the 4.9 but I think I need to get the car running right before I hit up all the mods.:bouncy:
And before anyone asks, yep the car runs like a raped ape with a firecracker up his butt scaring all the Ricerized Hondas and other Imports every day of the week.:cloud9:

That's actually pretty common. The car I was going to get before the Cadillac (probably should've from all the expenses so far), was my cousins 1986 Fiero GT. This thing was rediculous. 16k miles. Really. The original owner lived a few houses up from him, he drove it like 4 times, then sold it to him a year or so back. So I joined alot of Fiero forums becasue I was going to buy it. In the "engine swaps" area, there's actually "aluminum Cadillac engine" somewhere near the top of the swaps. Then I asked them about it becasue I'm a valet, and I drove a 4.9 Coupe DeVille that night. I liked it. But to make a long story short, those things get that relatively frequently. A guy around me (attends many local shows) has an '85 style (like pictured) with a 350 in the back.
??? lol.
Here's the Fiero I was gonna get...

Yeah...a little dirty...but you get the idea.

The O2 sensor (my car has 1) for my 4.9 was a Bosch, and it was $20. Not a problem with it since.
I just did the Ford injector swap... I gotta say, definitly do it! far better idle, noticeable more power, seems to be better fuel mileage, it was more involved then I thought, but very much worth it.
The Allante intake manifold *does* flow better, I am not sure about the Fiero, but atleast on the Caddy's, it would be in the way of the master brake cylinder, that would have to be relocated... alot more trouble then it is worth.
My father has an '88 Fiero Formula, 2.8 V6 w/ 3spd auto, it was his daily driver for a really long time, it has 167k miles on it and runs great. It hasn't been on the road this season, but he had it out of the garage today.... I never used to like it, as I love huge cars.... but there is a certain thing to it that I do like, very neat little car, and with a nice powerful Caddy engine, and a 5spd, I could just imagine how good it must be.
It seems like over here, us Caddy guys have our own thoughts on what to do with the 4.9, and you Fiero guys have the same... we should combine and use all the knowladge to get both the Caddy's and the Fiero's that much better.
my '93 Coupe is my baby.... but I do have a complete Northstar...in pieces.... and my plan with that is to rebuild it, and if I want an easy swap, buy a '95 Eldorado ETC with a blown engine..... or if I want a much more difficult swap, buy a Fiero
Though my next vehicle is going to be a Jeep, I need the change

Here is my fathers '88 Formula, from what I know, the Formula is basically a GT with the SE body, and in '88, it was the best year as they have the Lotus-tuned suspension and stuff. 2.8 V6 HO and TH125, it actually has a really nice sound to it... of course it idles rough... to me... bounces back in RPM, which my father said all Fiero's do that.
The car is not perfect though, 167k miles, it shows in some ways, but my father takes excelent care of his cars, and it is solid.
He wants to repaint it all in Cadillac Pearl White... no more two-tone, and I tell him to swap in a 4.9, but he says if he dosn't to a 2.8-3.4 conversion (then build up the 3.4) he would want a Northstar... even after I told him, he really dosn't understand just how hard it is to swap a N* into anything... all the computer stuff..... a 4.9 with a carburator, very easy, and very fast.
This is the car my father had all when I was growing up, my mother had a Chevette, a very neat little car for it's time, did what it was made to do.He has had this car since 1990 or 1991 and bought it with 70k miles or so for like $3,500.
Very cool little cars... just like the Lotus Elise at the track tonight... but I dunno..... little engines in little cars don't do much for me... even big engines in little cars.... I like huge engines in even bigger cars that is what makes me all happy inside

I'm sorry if you thought I meant that was an '85. I meant that another one around me had a 350 in it. That one was an '85. The silver one pictured is an '86 GT with 16k on the clock.Capt Fiero said:
BTW: The yellow one I mentioned... I was in traffic the other day. When I was pulling in to get gas, I see the yellow 350'd Fiero. It looked so funny to see a sorta 80's technology car that sounded like a Chevelle. lol.
:alchi:
I know when we replaced the cat on the '93 Coupe, I fired her up....damn, did it sound pretty nice.... had a gurgle at idle, and when I raced it up... it was just crazy.
I always thought on the '93 Coupe, a sweet exhaust would be a dual setup (not true obviosuly) with side pipes exiting behind the rear wheels, under the quarter panel... I just think that is cool
