Buckling under full throttle acceleration is the only concern with this method. I still need to sit down and do the math to see how much of a concern it would be and what could be done with material diameter and thickness to alleviate. However, any additional tube diameter increases the needed offset. Additionally, I need to decide if I just want to make it work with the current wheel/tire setup or if I want to make it with additional clearance for a future wheel width increase (that would also require other mods).

Interesting. I had not seen that thread before. That's exactly what I was thinking, but it sounds like you don't think its a good idea. Have you looked into other spindles or setups that could use the stock mounting loc? Kind of like how the Camaro/Firebird guys can put a 4 link rear into a space that was designed for a leafspring setup. I know the R&D would be expensive and time consuming, too bad we didn't have a larger customer base. I've wondered if another vehicles spindles would work and offer a brake and bolt pattern upgrade at the same time. Vette, Viper, GTO/Camaro, Cadillac......

I like the simplicity of the simple offset I just need to validate the math if I go that route.
As for adapting something else... anything is possible, with enough time, skill, and $$$. I have several ideas, but it is way, way down the priority list

The cap for the bandsaw table came in earlier this week and I finally got the on/off switch installed for the band saw and belt sander. Now I just need to buy a new 48x6 belt for the sander and I can start putting them both to work.

I'm finally starting to look for an engine and I was wondering if you would recommend a Gen III or Gen IV from an ECM standpoint. My understanding is that mechanically the engines are the same, but that with the Gen IV you have to do more conversions in the programming which can lead to less accuracy. Given the DoD didn't get working with you F40, I'll probably go with a DoD delete from the start and just rebuild the engine while I'm at it. Give all that, I'm thinking Gen III would be the way to go. Any thoughts? ------------------

The 05 and 06 engines (24x) with the e40 ecm are easier to integrate all the other systems w/o the BCM.

It has been a couple of months since my last update.
I have used the bandsaw and belt sander quite a bit and really like them!
That got me thinking about other handy tools that I should add to my garage. On Black Friday I added a 20 ton harbor freight press to the garage. I am not a fan of harbor freight bolts, so all the hardware was swapped out with higher rated and more reliable parts.
I made some room for the press next to the belt sander (did I mention I need a larger garage):
Now the reason I wanted/needed the 20 ton press was to get this:
The finger press hasn't arrived yet, but this is what it will look like once I get it and assemble it. With it I will be able to bend much thicker metal with minimal effort!
As you can see in the pics above, the LS4/F40 Fiero found a spot in the garage for the winter. The plan is to pull the drivetrain for the next round of upgrades. I took advantage of a black friday sale to get a hairdryer from borg warner for it! I can't wait for it to arrive and try to find room for it in the engine bay.

So this showed up today!
This was inside...
Borg Warner S369sx-e supercore. It is the latest generation turbo from BW and supports 950+ hp without the excessive size of the 400 series turbos, which will make it easier (but probably not "easy" to fit in my engine bay). For phase one, I am "only" looking for 600 whp on E85, but wanted good reliable turbo with room to grow.
Here are the specs
S300SX-E SuperCore Assembly 9180
69.00mm / 2.72'' Compressor Inducer Dia.
91.44mm / 3.60'' Compressor Wheel O.D.
73.37mm / 2.89'' Turbine Exducer Dia.
79.75mm / 3.14'' Turbine Wheel O.D.
Straight Compressor Outlet
Here is the compressor map:
The exhaust housing is a T4 80 mm twin volute with 1.0 AR designed specifically for the S300sx-e supercore series, but it hasn't arrived yet...
