Re: project silver - 1987 fiero coupe street car
Looking good! Are those Konig Countergrams? What size(s)? I would be interested in buying them from you if you do go to a different wheel and tire combo.

Re: Lz9 + 4 spd manual trans in 86 GT swap
FWIW when I did a deep dive into research for the LZ9, I recall the tuning for the VVT was not straight forwards and it was advanced and retarded all over the board vs having a crossover point. I think it is a good call to delete it if not running the stock ECU, unless someone can find the tables fr...

Re: 1988 Fiero track car
That looks like a good solution with minor fab. I have been considering using an oem shifter and cables from another car for my LZ9 F23, VW shifters are another good option as the shifter has a ball pivot, and I have been considering a Honda shifter and cables as well. I will need to modify the tran...

Re: Lz9 + 4 spd manual trans in 86 GT swap
The Lucerne water manifold and alternator location may be the best for a low fab 3900 install. Think the hinge box just needs a trimming, and maybe an idler bolted to one of the PS pump mounting holes, but also maybe not. https://i.imgur.com/aX58kyt.jpg AC or and idler down there needed: https://i.i...

Re: 1988 Fiero track car
It is the tight bends that do it, and I am having a hard time imagining how you will avoid some tight bends with the strut tower there. If you do end up modifying things (on the trans side of things), since there is no exhaust on the firewall side of the motor and looks like plenty of space with the...

Re: 1988 Fiero track car
Very cool, Honda makes some great motors and transmissions. Are you planning to modify the shifting linkage on the trans to reverse everything?

Re: progress on the banshee...
Nice simple solution on the line lock. Car is looking nice, maybe I am biased as a bumper pad owner but I just think the bumper pad Fieros are the best looking of all the Fieros when they are at a nice ride height with a good wheel/tire combo. They just really capture the 80s Italian sports car vibe.

Re: The Mule rides again (sort of) - pics.
I have used black silicone vacuum line for protecting harnesses and other tubing from rub areas, I just split it with a razor and zip tie it around the offending harness or hose. It is very flexible, durable, heat resistant, and can be found thin walled and in a large range of sizes and wall thickne...

Re: rear sway bar?
If nothing else, the way you can tune the rear of the car to behave how you want is worth having a rear swaybar. I have messed with rear sway bars on a bunch of different vehicles to dial out factory understeer, and my friend who races spec Miata does a lot of adjusting of his rear sway bar dependin...

Re: Installing 3500, LZ4, for the time being
Bummer about the rear main seal, one of the few seals I always replace on a used motor for any car since it is requires pulling the engine or trans (or both) to replace. Worth the <$20 and 10 min to replace. Especially when motors get pressure washed by the pullers and sometimes it is very hard to t...

Re: Extremely Good Thread on Camshaft Design and Valve Events
A good thread from LS1 Tech on people running reverse split cams, the common one being the TR230. With the LS1, it takes significantly better flowing heads and intake before a traditional split can be fully taken advantage of. A traditional split cam without the supporting mods sacrifices a lot of t...

Patrick are you using the Seville calipers with Grand Am rotors? If so would you be willing to share your CAD files (or dxf) (or even just a drawing with dimensions) for the brackets used? Currently have Grand Am stuff on all 4 corners and a Blazer MC, no ebrake. I have some Wilwood spot calipers I ...

Re: Steering rack boot clamps
I would say a spring clamp in that spot never hurts, I am used to seeing them on other cars, I a$$ume the techs would slide them off before adjusting tie rods, but you could always do that yourself prior to bringing it to the alignment shop if you were concerned they wouldn't do it. I run zip ties o...
