Would be good to get a detailed write up of the ibooster install

BUMP

We need some updates

2mAn Nothing major in terms of updates, and I feel as thought I would not do the updates justice, as the guys over at Highline Motorsports are really the ones doing the hard work right now.

It's definitely getting close. The booster install did prove to be relatively challenging on the wiring front, but more so just finding the actual connectors, as we didn't want to hardwire it.

I received an update from them about 2 days ago, the harness for the car is mostly complete.

Bosch iBooster Gen 2 is currently installed in the car.
The ECU side / harness side is complete, I believe, and they are currently working on finishing up the chassis side of the booster, with things like the pedal position sensor.

I should have a bigger post coming soon, but we haven't really had a time to go into the fine details of what's been done. Had a few hiccups finding all of the pieces to make the booster work.

But, here is a temporary photo of where we're at!

i wanna see some videos of this s14 killer! i hope you get it back in due time.

The guys at Highline Motorsports finished up the harness in it's entirety and shared some photos.

We're on the final stretch of everything just getting buttoned back up and then I should have the car home before spring to finish up a few more things on my list before the fun season.

Fully hand wired from the ground up with this engine in mind. Couldn't be happier with the results.

Looks great, cannot wait to see this on the dyno

she running yet?!

What inspired you to go to Highline? Did you move up to NY? I live ~10 minutes from them and I always love driving by and seeing the fleet of E30s

Damn that harness looks nice. Ecumaster EMU Black is a good ECU for sure - Hell of an upgrade from a Tec3

+1 for install info (clevis? wiring?) on the iBooster.

[eternal24k]

any updates?

[McGyver]

Wow, I remember helping you with the m42 in Berkeley. I wondered what happened to you.

Glad you made it to VT safe and finally get to live your dream of a high performance m42!

I received many great referrals to them, and eventually, Dave, the owner, reached out to me while I was having issues with the ECU and Wiring, and offered to assist, as I couldn't find any shops locally to me willing knowledgable about tuning an engine from scratch. And those that were, only worked on cars with "1,000hp or more on LS platforms" or Nascar engines. Dave and team does amazing work, and they're very knowledgeable. Not to mention, he's willing to attempt crazy projects for the first time before anyone else (iBooster Install).

I can get better photos soon. Turns out, it's plug and play for the most part. Some fab was needed at the pedal for the clevis, but according to the shop, you just wire it up and it works. This is also what we read online, but I'm sure there's more that went into it. It was made a bit more difficult because I'm using the RHD ITBs which are unfortunately made for E36s, so we still had to relocate the booster to fit without modifying the airbox.

any updates?

Lots, and not a lot!
Everything is installed into the car and working. However, the injectors will not fire under command of the ECU. They will fire with Key On, Engine Off position only. Dave is in touch with ECUMasters to find out what the issue may be, but this has been narrowed down to being an ECU issue, or something that was just set up wrong in the EMUBlack. This is the last thing left to diagnose. Everything else is working well.

We did swap my radiator for a Mishimoto radiator, expansion tank, and fan (the e36 kit), but had to make some modifications to the loop due to deleting the engine coolant pipe on the drivers side, so we had to add a reservoir loop somewhere.

Just moved back to VT after my last startup was acquired. Still working in startups, just out east now where I don't have to deal with SMOG. ;)
Definitely miss the Bay, and I'm sure I'll be back there eventually, but I've been grateful to be in VT during Covid, as the state handled it very well and we're 100%. back to normal here.
Hope you're doing well! I'm planning a road trip with my E30 either this fall if we get everything handled, or next spring where I'll be on the west coast.

[McGyver]

Yeah, I remember you talking about doing a built m42 or a turbo and I was trying to talk you into a swap if you wanted more power. All because of smog problems, so that's cool that moving allowed you to do the thing you originally wanted!

I'm good. The green car and convertible both got totaled (other driver's fault both times), so now I'm DDing an f30 335i 6mt and have am '89 325iA sedan for fun. I think I'm going to move east around March 2022, so hit me up if you're in the bay before then!

Depending on where you are in Vermont, come October is a great Vintage Car show in Saratoga Springs at the car museum. Put on by Frank Greppo and his crew It's a good way to meet BMW nuts on the east coast. Good luck with your build.

My car is in Saratoga Springs right now.

It's a decent drive, I'm in Burlington. But I'll definitely be there. I'm trying to be optimistic that there's a chance it can be done for Wolfsgart in 3 weeks. It's literally down to the final push.
