New booster option for e30 - Bosch iBooster

Yeah, I saw that one yesterday, but it seems pretty crusty. Wish we could read the part numbers on it - I doubt it's very expensive new.
Really thinking about one of those CRV boosters though. Could always swap out to the Tesla RHD MC later on. What I like is I could get this put in long before doing a swap... keeping my E30 operable is one of the reasons I've been able to hang onto it through marriage and two kids. :p

You know honestly, the flange isn't that much different on the Model-3 booster. It seems like it would be relatively trivial to move the bolt centerlines less than 3mm over:
I think the pictures are deceiving too. It looks like the connector sticks out to the side, but I think it goes pretty much straight down. Should easily fit within the huge envelope of the original E30 booster, no?

I want to say I found a RHD photo showing the part number and it was the same as the LHD... it might just be a casting number and it gets a part number when it gets cut one side or the other and assembled with a booster.
...a Tesla part number doesn’t do us much good because we can’t order from Tesla.
I think the model 3 (ibooster gen 2) would absolutely fit anywhere a normal booster would fit. The challenge I have with the n52 intake is extreme, and I don’t think it would fit with that constraint.

I'm pretty sure in reality it's no wider than the gen-1 booster. It's possibly shorter?
I have a line on a Honda booster for a song. I'm having a hard time not buying it on a whim.. there's a Model 3 MC for pretty cheap too. for a RHD booster, you're looking at least $500, plus the connectors. I feel like moving some bolts around at less than half that cost could be worth it?
Looking at it again, the ix is kind of oddball, everything is in a different position relative to the RWD E30. I think for sure, the Gen 1 will fit easily. I'm not certain about Gen 2. I think it's a "maybe".Last edited by nando; 10-02-2020, 03:37 PM.

Holy cow! FredK in da house!
To give some color to my discussion with hubcapboy - the N52 three stage manifold takes up a shit ton of room. Basically, if the Model S booster clears that by a finger width, it's going to clear pretty much everything else by a mile. IMO, it makes swaps of all kinds a much simpler and cheaper proposition.
I'm still not sure about the model 3 / honda booster. It probably clears a lot of typical swaps (certainly M5X). It could clear the S54. Clearing the N52 is a bigger hurdle.

I just got to try it. Compared to my current brakes, it feels much smoother. No delay.
it feels like when you're riding a nice e-bike, it doesn't feel like the motor is helping but you just have a lot of wind at your back.
The true test will be if it feels uncommunicative or overboosted on the road

It looks like the Honda just has a steel flange instead of aluminum.
The Gen2 doesn’t seem to have swappable flanges

Well, the flange *does* unbolt, it's just a much larger stamped piece, and there are more bolts. But I'll bet the Honda Accord and Model 3 bolt patterns are the same, potentially a cheaper option for other E30 swaps.
Funny enough, there are about as many Model 3s sold a year now as Accords. So really, choices should be plentiful. Who knew the EV revolution would benefit our old car hobby..
