Real Fiero Tech

Seriously....

Any elaboration? Just trying to get a little hint...

its sitting? WHY?
ill PM him about this, i want this car

this thing sold?

My aesthetic is different than most people's I guess. It's not that I don't care, it's that I don't think "so clean it's vacant" looks good. I don't like VW wire-tuck jobs, for example. So where/how are these E/PCM's mounted stock? Inside a box in the engine bay? Under a splashguard? The ...

You're a fountain of part numbers aren't you? The Northstar reluctor wheel is in the middle of the engine, so it's less likely to be removable than the one for the LS series... However, there's a possibility that the 58x Northstar crank has a removable reluctor, which may make it possible to swap i...

How will you be constructing the button? There are factors here that make a home-brew fatigue test less effective than simpler methods. First, the material (fatigue) properties of 6061 and 7075 are already well known (just an assumption of your primary material). If you're using steel construction ...

I figured you would have the foresight to cut deeper valve pocket reliefs. Get the heads ported and flowed and take advantage of some more lift! I know how much of a pain of an ass it is to take the valve covers off these engines, even in big Deville/Seville engine compartments but I think it would ...

I figured you wouldn't be worried!:)
Better I am sure it will be. The nose drop is quite annoying when you stand on the brakes and with any kind of upgrade to the braking system I am sure it is a chin dragger for sure!

By looking at the head flow sheet posted, you are all out of flow by about .350-.4" lift. Increasing lift probably will give you some gains but I am betting you will be limited on piston to valve clearance since those valves want to kiss the piston in stock form already. Duration increase on th...

My favorite story from the turbocharging days of F1 was when Cosworth found a way around the boost reduction blow off valves during their first year by running such a large compressor that even when the valve was open that was supposed to regulate boost pressure across all engines, the turbocharger ...

Ah I understand now. I haven't really done any calculations on what % of pro/anti dive the Fiero has, any idea and how much you will change it after the sub frame rotate and lift? I guess this would be the easiest way with the least modification, if you messed around with the upper control arm mount...

So you are lifting the body up an inch and using washers that are convex to center the bolts in the subframe? Am I completely off?

What a drama fest... I have read that the earlier LSx blocks are less desirable than the newer the blocks for various reasons, the improved lifter galley oil feed passages being one of them, but this isn't gospel. At higher RPMs I can see increased and equal flow of oil to both lifter galleys helpin...

I am on the eastside. I havent been to any JCF meetings in almost a year and a half, You know how life gets in the way of fiero projects but I will probably be more active in the future. Ya that intake should be fine, I am just used to seeing things on those intakes fall apart after 100k plus of Cad...

I have no real number data as far as how much boost you can push into a Northstar plastic intake but I have seen other similarly constructed GM nylon intake manifolds take almost 20psi BUT it seems all of GM's factory 100k warranty turbocharged engines have always switched to a non composite intake ...

You do not want them. I am a Cadillac tech and I replace those things about every 50-70k miles on any FWD Northstar setup. Since they are close to the exhaust manifold they get hot, the rubber weakens, and along with all the torque the Northstar and the 4t80 make they tear and separate leaking all t...

Get 4 tubes of Lubriplate 105, squirt them all into a big mason jar.
add two heaping teaspoons of moly powder, preferably from dow corning
add about 1/4 qt of straight 30w oil, brand dont matter
mix as well as u can
thats what i use to do any motor at work since gm disc. their EOS

I have one apart right now actually. It is a Saab transmission, has an avaiable LSD(torsen) option. Comes out of the 9-5. The diff is large, seems beefy. Quaff is the LSD supplier i believe. Shift forks are a brass alloy, first and second gear use triple cone all brass syncros. There is a 6spd conve...

I wonder how they keep the cats from cooling off....interesting.
