i swapped to ix booster with wilwoods up front and with new fluid those feel great. The benefit was the part didnt have to be modified to work

... I just never got the wow with any oem setup I’ve been in.

Outstanding reply and feedback. I feel the same way about stock e30 brakes. They do the job, but I don't get a performance feel out of them like I do the rest of the car. They work and don't fade in the moderately hard driving I do. But I want more.

I've been considering a brake master & booster retrofit for a while and I think your post just convinced me to do it.

How do you like the boost level of the new booster? Does it give more assist or how is the feel?

So not everyone is going to like this answer. It feels stock, not like an e30. I’ve never driven an E90 that’s like 300lbs lighter and with some aggressive pads and rotors, but...um I expect this is how it feels.

It will stop the car. I always heard solid quality on oem e30 brakes was supposed to be able to make it skirt skirt really easily, but that wasn’t where I was. I’ve driven a couple e30s and I’ve never been super impressed with the brakes...like they weren’t ever bad. Idk if it was just wrong pads or something but I just never got the wow with any oem setup I’ve been in. I also didn’t want the it just slams to a halt 4 pot willwood setup I’ve been in a few times. I remember this Miata where it would brake in a violent fashion like at a touch. I understand why, but that’s not an enjoyable experience for a street car...and I know like at that point it can be adjusted.

the e90 booster feels natural with a normal car onset. It will stop when you press the pedal, and it will do it quickly. I don’t feel a huge bias in any direction. I wouldn’t be scared to let someone drive it and have a fear that the brakes would be tricky or odd. It natural. Now I don’t track it, and it’s only ever been stomped down a handful of times, but I have zero complaints about stopping ability. The only thing I would have done differently is have gotten e46 m3 calipers and rotors up front...and that’s more just for the bling factor. I’m sure it would be excellent for a track setup with a really linear onset a definitive “bite point”.

I will add the caveat that I also have ABS still. I’m not sure how it would go without it. I don’t think it would be to much different minus knowing it’s your fault for that flat spot.

Now I don’t know how it would feel on a 4 lug setup. I would be interested in that for anyone using one of these boosters for a swap.

I used an e90 euro booster...

Cool to see the torch stay lit, keep it up!

I used an e90 euro booster, and these adapters. Here’s pics of the part number, and it compared to the e30 booster. I leave no mysteries.

Here’s how the brake booster turned out. I flipped the master cylinder on the booster so the vacuum line popped right in. I used the e90 clevis pin and tossed the spring. Pictures show you all the extra clearance. Just had to bend the lines a little. Super easy swap. Now I just have to hunt down an engine.

Here’s how it’s looking.

Few more cause it’s been a bit.

So....pfffft I’ve made some progress, but not enough. Here’s where we are. Waiting on parts still.

[onlyindef]

So I got a new ecu, along with a turner chip, and some green top injectors. I’m pretty sure I have a leak in one of my new injectors though. Little bit of a rough start if it’s been sitting, but I’ll get some replacements in. So once that’s done it will be sitting real pretty.

[onlyindef]

Oh I’ll include some on this as well when I put it in. It’s an e90 euro brake booster.

So I suppose it’s update time. Let’s see since last time I got some sports seats back in it. I cleared up a number of small things as well. I fixed the vacuum leaks last time, and I got some new ones! The side valve came out of my tb, rtv back in. Got better, but wasn’t fixed! Cleaned the tb, icv, tested the tps, all the hoses have been replaced. New blue sensor, and replaced some relays that didn’t pass the test. I chased it down to either the intake manifold, or injectors with smoke test/can of throttle body cleaner.

my solution? Green top injectors, and a new gasket. I thought a little go fast would be nice to so a tuned chip is going in as well.

let’s see, I’ve hunted down the vast majority of parts for the 5 lug, so hopefully that’ll be happening this spring.

[onlyindef]

Replaced all the hoses, and added a catch can. I’ll empty it in a few weeks to see how full it is. I have a new o2 sensor to put in, but I ran out of time.

So some interesting thoughts on this car. I received the car in much poorer shape in the beginning of 2018 from a person in Santa Fe. Some of the parts being taken makes sense. The seats, and wheels...yeah I get. Some things I don’t, most the vacuum lines were torn up, the intake boot, you get the idea.

so issues to address
Front shocks pretty sure are torn up.
Gona try an amazon o2 sensor to see if it can help with it running rich
theres no check engine light. I see it light up on key position 2 when all the lights come on. This can’t be right.
the obc screens cracked, and the light just went out.
ummm...not much left on my suspension round up.

maybe I’ll get lucky find some seats in this god forsaken desert.
