here is where I am at so far:
- Deleted the power steering and that freed up a lot of space and no worries about leaks.
- used engine harness adapter from redline motorsports which took all the guess work out of the wiring and it comes with an obd2 port to scan for codes and view live data. It was pricey but worth it. You send them your dme to disable ews and anything else you want, all included in the price.
- Deleted the AC, but kept the condenser to use it as a mount for the electric fan. I used an e34 fan, larger diameter but it fits on the e30 condenser with a bit of bending and persuading the metal brackets. This thing creates a tornado on high speed.
- deleted the CCV system and just used a small breather filter at the valve cover and plugged all vacuum ports on the intake manifold.
- Used the bmw euro diesel mechanical fan. I have about 1/4 inch clearance at the bottom between fan and radiator core and about 1/2 inch at the top. Not sure why but it works, could be because of how the engine is sloped down slightly towards the firewall.
- Used a short cone filter and supported it with a 3 inch diameter C-shaped electrical conduit bracket and attached that to the Threaded hole on the oil filter housing where the PS reservoir used to be.
- Completed the e90 coolant tank install and put the hood back on the car. No interference at all with the hood closed and latched.
- Used e60 brake booster rotated 180 so the vacuum port does not interfere with the intake manifold. The port is Now on the lower left side by the frame rail. Even with that, I had to shave a couple of plastic brackets on the intake to get this setup to work.
-Got the front half of the driveshaft out of a 98 e46 328i with the zf manual trans and shortened it by about 2.25 inches and it fit perfect with the rear half of the e30 driveshaft (m42) and the CSB mounts like it would on the e30, not backwards.
- used the e46 fuel filter with built in regulator and mounted it to the frame rail. I might use the m3 rail with built in regulator later on when I can find one.
-Used a couple Hoses connected together with a 1 inch pvc coupler for the lower radiator hose to get the right bends
- Used a dodge neon turbo upper radiator hose and shortened it on both ends. It has the right bends and fits perfect.
-Last issue I have to tackle is the exhaust from the manifolds all the way to the back. Used Z3 manifolds and welded the air injection ports shut.
- swapped out the 4.10 small case diff for a 3.15 medium case from 1998 z3 2.8L. It’s a direct bolt on, did not even have to swap out the flanges
