Oh and I forgot to mention I was only launching at 1psi of boost. I tried launching at 3psi of boost once and blew off the tires!
Bottom line is this car will run 11's if I can hook well enough to launch at more boost. Problem is my GA GT rims are only 6.5" wide so a 225mm wide tire is about all they can take. I want wider tires but will need to go aftermarket rims and any more width in tire will require coil-overs as well. Time to start looking.

A-body HD hub carrier swap -> 5x115 bolt circle
Use '89-'94 Grand Prix wheels on the rear... 16x8 mesh style. I'm running 255/50-16's on mine.
One the front, use either '89-'91 LeBaron 16x6 mesh style wheels (virtually identical to GP wheels),
OR
Convert front to 5x115 and use '93-'99 Bonneville wheels, 16x7, also mesh style and identical to GP wheels.

a lot of them come in 5x100 in 8" widths - but you can get 16,17" rims up to 10" wide in 5x115's
so you can get a pair of 5x100 rims for the front and a matching pair of 5x115's in the rear with coilovers

Will, converting the rear to the 5x115 bolt pattern sounds like an easy task. Now the question is what does one have to do to convert the front to 5x115? (keep cheap fiero owner in mind here)The Dark Side of Will wrote:A-body HD hub carrier swap -> 5x115 bolt circle

if you have a spare set of front rotors and some 1/4" steel you can part off the rotor portion, weld a disk over the stock hub surface, drill through it and the hub and install new mounting studs.. its a little bit of work but makes for a quick strong cheap 5x115 hubThe Dark Side of Will wrote:Street Dreams knuckles with my hubs (not cheap).
Custom billet hubs for stock knuckles (Held may have some...). Can be cheap depending on your machine shop access.
That's about it.
it just spaces the wheel another 1/4" away from the knuckle + the thickness of a new rotor that slips ontop of the hub so about 1/2" total backspacing added

They always taught us that cast will weld, but it's fatigue resistance at the joint and the likelihood of cracks appearing later is very high. Without good preheating, it's also likely to crack as the part cools off from the weld, as the rate of expansion of the steel weld and cast part are different as well. They usually use a stick welder and some sorta special Nickel alloy rod (cuz it's ductile, I think?) to repair castings and such.Kohburn wrote:its really not that difficult (atleast with flux core and the amperage turned up to get the heat into it)The Dark Side of Will wrote:Aren't the stock front hubs cast? Welding to them will be fun...
I did MIG weld my steel pickup tube on my DOHC to the cast iron oil pump body - it was only in with Locktite! Maybe it's cast steel, or good iron. Wasn't a probelm when I tried it on my old pump and dropped it into a bucket of water. I put two beads down, we'll see.
