Don't give me your CRAP about 206 rwhp with a crimped exhaust. Maybe everybody should go crimping exhausts... TROLL!

There is a very noted difference in the length and routing of exhaust between a Fiero and a Cavalier. You also can't use the 3500 'header' like manifolds in that generation of J-body due to space constraints, so Weatherall's Auto was using the log front manifold and crossover, most likely from a 3500 van since that is where motor came from, and from the pictures he still had the full Cavalier exhaust installed.


Hello all 60*ers The WZ3500, yup I said it...
Why is the dyno sheet of a 3500 in an actual Fiero 'crap' and dyno video of a 3500 in a Cavalier more representative of a Fiero swap?[This message has been edited by carbon (edited 01-28-2014).]

If anything, that should tell you about how much variation there can be in swaps. We already discussed the variation in dynometers, that everyone keeps forgetting. Post dynos of 3500s in their original car with no mods then to get a baseline. If a modded 3.4 Fiero can match that power, which is a fact, why is he still being a no-life'd troll? His comparisons are useless because mods vary. It's crap because he keeps trolling like its the norm. His posts go in circles. All he does is repeat him self. He serves no constructive purpose in this thread. He had dedicated threads for his trollishness but in the end no one cared about them. It's like he's personally insulted that iron heads can be ported to 'hang' with aluminum heads. Poor baby.
This thread is about my car/engine not a motor that will never go in it.[This message has been edited by lou_dias (edited 01-28-2014).]

iron heads can be ported to 'hang' with STOCK aluminum heads.
At which point the Iron heads are maxed out and the Aluminum heads are just getting started.
Why can't you wrap your mind around that?------------------

I can get my head around it but AL trolls seem to be insulted by this.

As soon as I finish my move, I'm going to get back to working on my Fiero again which has been in storage for the past two and a half years. I'm seriously debating just going with a 3500 or 3400 block and doing this swap (with the iron heads) so I can keep the factory intake, and STILL make use of the roller cam.
Lou, do you have any videos on YouTube where I can actually hear what it sounds like? The race videos were cool, but it's hard to actually hear the engine?
If you have any where you're kind of doing a walk-around, or a simple cruise with maybe a WOT thrown in there, I'd love to see it. Thanks!

I have dyno videos posted on my loudfiero channel. I'm running a Flowmaster 55 series muffler. Here's one:

It seems I may be returning to my 250 ft*lbs ways... I found that my CPS and knock sensor wires were sitting against the block and transmission just underneath a header. The heat caused the loom to melt and the wires are brittle. I wire-tied the wires away from the block and now 80% of the time my engine runs like a champ again. I believe the signal was arcing out on the block...or atleast being interfered by it. The wires are very brittle and I still get some temporary timing issues but overall, it's a huge improvement.
After I finish moving into my new house this weekend, I'll be dropping the car off for maintenance, including new knock and CPS wires...then if that all works out, dyno to follow as I'm sure I'll need a new tune...

After some weeks... So some rerouting of sensor wires, the car was running better. Still had a weird skip. Slipped a belt so I had it towed to a mechanic and told him to investigate the skip.
Turns out my ignition module was bad and I was missing a cylinder or perhaps two. It wasn't the coil packs or wires. Should be running like a champ again. Looks like it will be back to the tuning drawing board.

I also added '88 cradle adapters because I though my body roll on hard turns was causing the spring to hit the tire in the back... well when the mechanic went to install the adapters, turns out I had 0 pressure on that strut. Well, that explains my twitchiness going into turn 3 a few times last year... Waiting on new coil over assembles from Arraut Motorsports now...
If it's not one thing it's another. :/

Zero pressure in a strut isn't a bad thing... zero pressure in just one would be weird, but you could have depressurized the other to match.
The Koni custom shop routinely ships depressurized shocks to autocrossers looking to keep a low ride height and not have their cars lifted slightly by the gas pressure in the damper.
