New booster option for e30 - Bosch iBooster

[iman53]

Have you driven her yet with the new booster?

Unfortunately not yet, I bled the brakes this past weekend and that went well, I tested it on jack stands with the car on and off and there is for sure a difference when the booster is powered.
I won't be able to do much driving till I get a tune, so basically on and off a trailer.

I used the tesla booster but I removed the mounting flange from the rear. I assume you could do the same with the crv booster but because the crv flange is so thin I dont think youll need to. Heres some photos, I have custom mounts btw so your motor probably sits in a different place.

I also had to modify the brake pedal so that the pushrod wasnt at such a harsh angle, heres a bad photo of that.

Thanks! I'm actually getting ready to mount it tomorrow. I'll be making custom mounts and whatever parts I can. Looks like you've already been down that road. Looks good!

You used the crv booster? Do you have any pics of it installed? I'm totally ok with a bit of modification for the price. Mine was $360 cad with the connectors.

Has anyone figured out if this setup works with an ls swap? I rolled the dice on a crv booster. Hopefully it works out!

it’s not bolt in like on an I6 car, at least my car wasn’t. Modification was necessary, but yes it will work.

Any progress anywhere on being able to tune the boost through the CAN interface?

I made my own harness which looks pretty nice and wasn't at all difficult. the kit is pretty affordable, this is the one I used:

Anybody can do it if you have the crimpers and if you don't they aren't that expensive either. it looks better than a bunch of crimp connectors IMO. However, using a cut plug is undoubtedly cheaper.

I mean if you're offering a service since you have the know how and materials, it would save me the issue of dealing with scrap yards... Of course, nothing is free!

I can confirm that the only RHD piece I picked up was the master. The booster came from California.

The only wiring on the master is the fluid level switch, which just clips to the tank.

Reminder for anyone who is waiting for one with pigtails: call a yard that dismantles Teslas... when I did this they were happy to cut the wires on one when they took the booster out. The plugs are just scrapped.

yeah, the wiring is identical. Really, even the MCs are the same - they just drill/tap one side or the other depending on LHD or RHD. It's too bad there's no "realoem" for Tesla, because finding the RHD masters is basically impossible (or extremely expensive).

I watched for months before picking up an LHD setup with the pigtail harness. Partially because it was cheap, and partially because it had the harness. RHD ones were 5x as expensive or worse, looked like they were dredged from the bottom of the Atlantic Ocean, and none of them came with pigtails..

[iman53]

Looks pretty slick, happen to know if LHD wiring would fit the RHD set up? I've been asking around on ebay to source the wiring harness for the brake is pretty much impossible... I guess I can keep trying to get a RHD one.

I believe the booster unit is the same, so wiring would be the same. The only difference is the master cylinder. I think you’re better off calling auto recyclers off car-part if you want to buy an oem harness. But If you can just buy the kit and make the harness yourself it’s probably worth it. That’s what I am going to do

Here's the right-hand-drive master with some adapters that I believe will work. I haven't had the e30 lines connected, but I believe I have the fittings correct on either end.
