I just finished this swap on my EV-converted 8. I used a gen 2 iBooster supposedly out of a '21-23 Tesla Model S. I took measurements of the booster mounting studs and the firewall mounting holes and worked up simple brackets in CAD and sent them off to SendCutSend. The pushrod threads on the booster are metric of course (I removed the factory clevis) so I got a metric-to-imperial female adapter nut from McMaster and attached my existing pedal connector so there's some adjustability. The brake line ports on the booster are also metric so I got a pair of adapters for that too. Wiring was simple using the harness mentioned in a previous post. It's dead silent, pulls near zero power when idle and under 10A with normal braking. I can lock up the brakes but the pedal feel is softer than I was anticipating. With it off the pedal is very firm. From my online research this seems to be the nature of these things and may actually be vehicle-specific CAN-programmed. There are folks out there working on CAN controllers for these so maybe there will be something available soon that allows for easy adjustability. I did bleed the snot out of it and the bore on these is 26mm so right at 1". I'm going to take it to a local brake shop next week and have them look everything over, test the pressure at the calipers, etc, just to make sure it's optimal and safe.
One thing to note is that the I did it doesn't include a relief cutout for the pushrod boot area. I had one in the design but SendCutSend would do the bends because it would apparently deform it. So I removed the relief, had them cut and bent without it, then cut that area out myself.
