<![CDATA[1990 e30]]>It's been awhile, some might remember me from the fall colors cruise a couple years ago. Now that I'm bored with the LS1, it's time to put a turbo on it. I honestly just miss the violent nature of the turbocharged m20. I'm mostly interested in driving the streets. I like turbo systems that spool fast/early and hit hard. So i chose a Borgwarner S369  (69/72) with a T4 0.91 A/R turbine housing. This is probably the smallest you would want to run on a 346. It certainly will choke at full RPM, this is fine for me, I wan't quick spool for the streets. The rest of the system will be designed to be capable of the sub 1,000 hp level with my fuel pump being the limiting factor and obviously the SBE LS1 the weakest link here. I'll start sharing some pictures now and explain some things on the way. I'd love to hear suggestions if you have.

I have factory upper strut mounts and IE3 springs. Once I get it in for an alignment this spring I can certainly come back and post a number for you if you would like. 

Ah gotcha, for some reason I thought you were running coils/camber plates. Thanks! Good to know you can fit a decent tire without leaning them way in

Any idea how much camber you're running in the front? I'm debating switching to this setup at some point for a number of reasons.

Plenty of room, just need the right offset!

Good info. I didn't want to risk the wheels not fitting with the 330i brakes. 

For some reason I get no notifications of posts even though I have the notifications turned on. Is this a common issue with the forum?

Finally got the car on the ground. I approve. NO POKE!

I stand corrected! Always thought they were just too big, good to know

There are some 16's that will clear e36m brakes, but not the majority. As far as I know, no 16 will clear e46 330 brakes as they are slightly larger than e36m.

Well if having the spring removed and the shock completely compressed counts as “under load” then yes. Lol

Finally got around to installing the remote brake bias adjuster.

I got some new front wheels and tires. The tires rubbed on the factory wheel well liner so I made some new ones from hdpe. They clear with about a 1/4" to spare! Don't mind the socket spacer, I have some proper spacers on the way from McMaster along with some button head screws to replace those hex heads.

Yes, transmission jack...the spring is removed.

What’s the idea with das loopinator? 

KaiserRolls said:

My guess is heat, helps protect the sensor probably 

Correct, the loop serves to dissipate heat from the exhaust gasses passing through before reaching the pressure sensor. It also dampens the exhaust pulses as they pass through the tubing and absorbs vibrations. I also installed a 0.04" restrictor/damper just prior to the sensor just to make sure the readings are stable.

It was able to pump 1 gallon of fuel to the other side of the tank in 36 seconds with fuel pressure holding solid at 43psi. There was a fu*king tornado in the tank lmao. Very impressed. 

I've added a turbine back pressure sensor and a 3 port boost control solenoid. All plumbed and wired in...
