One of the items to replace for this update was the steering shaft. There was nothing wrong with it, but I never liked that it was a solid shaft.

This is a collapsable shaft and new u-joints from Borgeson. I will also be replacing my 20 year old AGR steering box with one from Borgeson.
In this picture the shaft is is already trimmed to fit.



This is the bushing that supports the steering shaft inside the column. Whenever I would drive the car on a hot summer day, I would notice that the steering would get a little sticky. I suspect that this nylon bushing swell up from the heat and causes the steering to bind a little. The holes are from the screws that I installed to pull the bushing with a slide hammer.



The bushing on the left is one that Vic made on his lathe. It is made out of Delrin, which I hope will be more stable with temperature changes.



Here it is tapped into the steering column.

Nice work Andrew...

What is your power goal for the car? What turbo?

It's a custom BW based turbo built by Work Turbo in Alabama. It has a 72mm compressor wheel and a Tial turbine housing. I'll Max out that compressor at about 20psi, which will be about 900hp at the crank.

Plenty for fun...

Today we decided to take a little break from turbo stuff and figure out how to upgrade the brakes. Over the last year or so I have been seeing electronically assisted brakes on various cars and on a couple of YouTube channels that I watch. The technology seems really cool and by all accounts they work great.

I started by removing the manual MC and the old mount for the clutch MC. There is a little rust here and there, but remember, this car was "done" 20 years ago. That area will definitely get cleaned up.



I figured a good place to start to be these brackets that I got them I was planning on doing vacuum power brakes. These are from DSE and it is their reduced angle bracket.







The is the Gen 1 Bosch iBooster unit that I got. It is from a 2010ish Tesla Model S with the adaptive cruise control. Bosch has a Gen 2 model of the iBooster available, but I don't like the looks of them and I am sure that none of the features of the new unit are even applicable to what we are doing here.



After a little welding, milling and hole sawing, we had the bracket modified to fit the iBooster.



It is bolted to the firewall here, but there is still a lot to sort out.



I am not really happy with how the pushrod alignment is looking at the moment. The unit might actually need to be tilted up at the front a little more, but I am already concerned about hood clearance. We will sort out the details the next time.



I really like the way these look. They add a little high-tech touch to the engine compartment.
