EspritGT1 Congrats on your project and for finally starting a GT1 building thread!
It also makes me want to finish mine as soon as possible.
I just wish I had more free time for it; but I will find it. Needless to say it I'm a huge fan of the GT1 Champion cars for as long as i can remember and of course that includes our beloved Esprit GT1. Being 35 years old means I've also just like you and Travis have grown to love 80's and especially 90's super cars.
I'm really liking your new wheels very much, but I will advise you to go wider on the front wheels to avoid understeering, and no worries as power steering goes, you can just use an electric pump from a Ford, Volvo (same) or anything like it. It's actually very popular to find electric power steering in new production cars. You can do a bit of research and also find a suitable steering rack with similar dimentions and ratios. That's the way I'm going about it. I will be using a Ferrari F355 rack that was left over of a car I parted out years ago... Since the F355 has almost identical dimentions as the Esprit I sould be ok and the electric pump will be mounted inside the front compartment.
There are also fully electric steering rack systems available off the shelf, but I would stay away from those. Hydraulic steering racks have 50+ years of development and their performance generally speaking it's seamless. Electric racks are barely starting to be half way decent when compared to hydraulic ones. If you want to read more about it:
But like I said anything with similar ratios should do the Job! Aside from being extremelly convinient for us Esprit owners; from the easy installation point avoiding the engineering of adding a mechanical pump to the engine belt system and the more obvious HP savings
The best part of these electric power pumps is that they have an input for speed which it's then used to adjust for power steering assist at lower speeds, and accordingly, in higher speeds more of a hard feeling to it for best handling/stability. Although you can just power the thing (- & +) and just use it as a reg steering pump, if you don't want to get fancy with it?? I hope this helps you!
