Throttle pedal, done.

I'm using the Z4 manual pedal which is considerably more svelte than an E90 pedal or anything else. The usual route is to use an E46 pedal and make a bracket and some...

Now that I have it running, I'll switch my E90 injector harness for an X3 one. E90 is incredibly short and won't reach the glovebox

X3 could reach the passenger seat. Or the backseat

Finally, here's what my exhaust looks like. 2" secondaries into a Burns merge, 2" to 2.75". Why 2.75"? Because 2.5" is too small and 3" is too big....

There are two versions of the thermostat. The X5 and most others. They both work fine, but the X5 one (left) has a 90 in the outlet that results in more direct and cleaner hose routing.

What do spark plugs look like? wet at all?...

One other thing that has been absolutely priceless is the OBD2 port.

The Z4 uses K-line bus communications and the E90 that my harness came from doesn't, so I had one missing wire in the...

The driveshaft isn't actually fabricated yet, this is a dramatic re-enactment to show how it will look. I cut it to the correct length and dropped it at Drivelines NW hoping they could just weld my yoke...

It all fits.

The oil pan is very svelte and is equal in height to the subframe, plus with the bevel it probably has more clearance than an original M20. Plus, being fabricated from 14Ga steel...

Yes, I ran out of things to do with the engine hanging from my rafters so I took an hour to install it. Super easy.
The headers clear everything just fine and I probably would have had 1/4"...

I'll fess-up. I did it....
