Wouldn't really be practical the way the E34 is built. The ECU box is in the way, and the partition it sits behind is connected to the HVAC inlet plenum under the cowl. On the other side the fuse box gets in the way. The only way to vent out of the fender gap or a vent in the fender would be to run a hose or duct through the wheel well or modify the partitions that hold the ECU box and fuse box and run a duct through them, relocating the fuse box and ecu in the process. The E34's design really doesn't make this turbo stuff easy, I love how my E34 wagon looks, and the car is good in many ways, but I would not turbocharge one again, at least not with an engine that is slanted. It's a pain in the ass.

Little details moving along with smaller items.
Pro Meth Kit going in. This will be controlled progressively with the LINK ECU. Fabricated a quick bracket with riv-nuts to fasten both tanks in place. Front clear tank if for the distilled mist on the intercooler. Black tank is for the joooooce.
More to come soon.

Tucked some hoses in behind the liner. I want to keep as much trunk space as possible. Dont mind my home depot shims. I still have to brace the pump mount to the top of the trunk.
Street car vibes.

Solid state relay for the pump is mounted in the trunk under the carpet tray. About 69% of the wiring is done for the pump control as of today. Ill need to use the level sensor in the meth tank to trigger a boost cut when the level goes low.
More systems= More complicated, more shit to break so I am trying to do this as reliably as possible. Heat from the SSR should be relatively low on 20 to 30 hz. It should dissipate heat well through the chassis with a bit of paint removed at the mounting point.
Plans to test the system once I get the LEDs installed. To do this clean is very time consuming.
