Not got any pictorial updates at the moment but progress has been great recently.
Most of the wiring is done, need to do the fuel pump still, got a few questions that need answering but I'm getting there.
Airbox is on, with brackets made. Expansion bottle is fitted, brackets made. Radiator is fitted. Ignition coil is fitted. Wiring loom is in place, and just needs a cut making in the firewall for the ECU to be mounted. Oil pressure switch is wired in. Exhaust downpipes are fitted.
Need to order some bits ready for some work on Friday, hopefully will be turning it over soon.

Got a load of work done today, lots of jobs that needed doing.
Radiator mounted:
Coolant bottle mounted:

Airbox mounted, just need some jubilee clips for the rubber boot:
[url=https://flic.kr/p/n1hoy1]
The loom leading to the ECU needs to pass through the firewall somewhere. I've decided to house the ECU in the space under the scuttle panel. It'll be stored in a waterproof case to protect it from moisture. So the I cut a notch in the firewall in front of the heater fans:
Then with the modified scuttle panel fitted:
E30 coil is mounted in the OEM E21 position:
The standard E30 oil lines don't fit on the E21, so I cut them and I will fit rubber oil hoses between the hard ends:
Fitted on the car:
Oil cooler fitted on the car, sat in front of the radiator, I'm hoping the space between the cooler and the radiator will be sufficient to allow for the electric rad fan.
Also got the adapter fitted for the radiator fan temperature switch, put it in the top hose so as to get the correct temperature reading. For some reason the top house mounting point is in such a place that there is no way that it could be done in one single bit of hose, so it has to bend away from the 'stat housing and then back around. As a note, that hideous blue anodized adapter will be painted black. I can't stand for colours like that!
Engine bay is looking very full now. I've got a few bits on order, including the somewhat vital part that is the ignition coil main wire to the distributor. On back order from BMW, so I can only hope that it turns up soon.
I'm "hoping" to start it over Easter weekend, but it all depends if the parts I need arrive in time. Fingers crossed.

Question...The metal you cut from the front panel to move the rad forward...would it be for sale ?

If I've still got it, you can have it for nothing mate. I'll have a look tomorrow if I get chance.

That would be great ! If you are not looking for any money for it would cold beers suit you better?

Beers are always good, but honestly, it's going in the bin, it's scrap to me so you're more than welcome to it. I'll dig it out and drop you a message.

Remember to flare the ends of the oil pipes before fitting the hoses, double ear o-crimps always look better than jubilee clamps for a better OEM finish. Dont want them popping off and loosing all your oil.
Looks great BTW.

Eddie,
Looks like you may have mounted the radiator hoses the wrong way round.
Radiator top inlet pipe needs to go to the top of the thermostat housing, not the side.
For the rad you are using it could be worth getting a metal pipe like on late 325i's which runs across the front of the engine diagonally from the thermostat side outlet to the bottom outlet on the radiator.

why are you using an extra temp sensor? you could use the standard m20 one.

standard is rubbish, atleast mine was...did the same thing, now it's ok.
I'd try to find the PFL airbox, its metal and more retroish looking.

Really?
Do you have any diagrams anywhere of the layout? RealOEM doesn't seem too clear.

Ease of access mainly, the mounting points for them are at the bottom of my rad and a PITA to get to.
