Real Fiero Tech

I got everything put together and got the timing done, and tomorrow it goes to the exhaust shop.

Oh, and I'm pulling off that red vac hose on the end of the two canisters. Putting the black one back on.

Just finished timing my '85 Fiero with 3.4L v6 and this is the first time playing with the new setup.

I guess once I get this thing all finished up I'm going to upgrade the fuel system. New pump and 42lb injectors and a chip burnt.

After that I will get the ported LIM and the Falconer heads on it. But by that time it will be this time next year.

42 lb injectors? why so big on a 3.4? you wouldnt' need anything more then 21's Hell even 19's would prob be too much.

because next year I would like to turbocharge the car and I don't want to have to buy 2 sets of injectors and everything...

what size injectors you have in it now? Stock 2.8 injectors should provide enough fuel for your 3.4.

I would look for 24 lb injectors if you go to turbo. Thts what I am running, and I am not maxed out yet on 11 psi and also using nitrous. I doubt I will ever get around to useing the 42 lb injectors I have.

Well, here's my temporary air filter setup until I get some pipes made:

Here's an update on my 3.4 '85:
I installed the headers and new intake but put the old factory intake manifold back on.



I have a ported lower intake manifold to put on the car, a new Cardone distributor, pushrods, springs, lifters, H-272 camshaft, and the ported heads to put on the car after the transmission gets rebuilt in the next couple of weeks.

Here are some pictures of my mess of stuff awaiting assembly:

Here are some comparison shots of the Falconer Racing ported heads, and a stock head I have laying around:

These heads will be re-machined for hardened seats, new seals, radius-angle valve job, and all new parts installed (springs, retainers, keepers, etc...) along with the 1.52 Roller rockers that God gave me.

I will be pressure testing the heads and then after the machining is complete I'm going to try and get them flow benched and post more numbers then.

We did some more work on the heads tonight.

First the bad news, we found that 3 of the 6 Titanium exhaust valves were pitted from corrosion caused from the previous racing application and we can not use them. it would be about the same as running a rat-tail file in the valve guides all day long:



So we ordered a set of 6 stock replacement stainless steel valves.

We will still be using the Titanium intake valves however.

Here are the intake valves with their brand new 30* back cut:

A friend of mine was around so he helped me pressure test the heads while my dad installed new hard seats for the exhaust valves:



We magnafluxed the heads right after I first got them, and they tested good. There were no leaks after this pressure testing either!

Hard seats going in:

Once we get the new exhaust valves in we will finish the intake side and assemble the heads. We may have to do some new porting, and we'll definitely be doing a valve job.

When all of the machining is done we will be CC'ing the heads.

A couple weeks ago I ordered a DIY HID kit for my Fiero. I'm using H1 style bulbs at 6,000K color.

Since my Fiero doesn't even have the factory head light assemblies, I just had to try and make it work. Well, so far it has worked:

Old head light comparison:


So far I only have the drivers side installed:



Here they are side by side. This would be the "dim" setting of the headlight control. You can see how obscenely bright they are compared to the old bulbs.


This is with the brights on (All 4 bulbs lit up):


When I get a chance I will attempt to upgrade the other 2 bulbs in the headlight assembly also.

I will post more pictures when it's all done.

Here's the install:

The whole thing:



Here is what my head lamps look like:



Here they are turned on. This is on the bright headlights setting:

Low headlight setting:



High headlight setting:



And like I said earlier, I am still planning on upgrading the second set of lights in there just don't got the money for that project right now.

I ordered a new Cardone distributor from here:
Auto Parts Giant Distributor Link

It is a completely rebuilt/refurbished OEM distributor. Brand new electronics, new O-Ring, incredible quality! I was so impressed that I just had to sqwak about it here...

Here is my old 20+ year old dizzy:


It had hearly a 1/8" of side-to-side shaft play and the new one has ZERO side to side play.

Also, of course the old one is all rusty and gross and I'm sure it doesn't work very good any more.

Here is the new one:




I put it in the car and noticed a huge improvement on startup and idle. I'm very impressed and very happy with my purchase. The cost of this piece, which I'm sure will serve me well for a long time was $140 shipped to my door.

If you are still using the original distributor in your 2.8 or 3.4 I HIGHLY suggest replacing it with one of these.

Why not just go to the 7730 ECU and run DIS? Cheaper, and even better startup/idle.

Exactly how cheap would it be to fully convert over to DIS?

1. Buy a dist. plug
2. Buy a 7730 ECM
3. Buy all DIS ignition components

Um, probably WAY more than $140 and this works just fine.

Go to the junkyard, you'll spend $40 at most on perfectly great components.
