I was up bright and early this morning to get down to Autoquip, I needed to buy a M42 spigot bearing which they didn't have in stock.
So I popped around Eko's to dump all my tools and conversion parts at his... Then drove the 40 miles there and back to our local branch of 'Euro car not so smarts' to pick up the bearing and a few other things, fluids etc.

Supplied me with the wrong bearing :roll: good job Tony suggested on taken the M42 gearbox with me :D

Popped literally around the corner to GSF and got one the right size (apparently they are all the same size, well on mateys computer anyway) :mad:

When I eventually got back after cooking the M40 completely it rattled more then ever and I'm surprised it actually made it back it was in the red the whole journey back 8O (as in the temperature gauge)

Anyway... I did take some more pic's of the engine on its way out etc but they are on my camera and the missus has fooked off to some 80's music Woodstock hippie gathering and nabbed me camera :roll:

Edit:

The M50 wanting to get in on the action

Image

Firstly we put the rattley waste of oily metal where it belongs, in the bin.

Image

Image

The engine bay was coated in some wax crap so that all had be cleaned off and then the whole bay was digressed and polished to make way for 24v's :wink:

After driving the 80 mile round trip last night to get an M20 clutch and fly wheel, Tony set about bolting the box etc to the engine, he had already modified the 'webbing' as required and cleaned it all ready to go, he's a good bloke... :D
(Thanks again Dave of the random kind for helping me out with said parts) :thumb:

Image

Next to go on was the Clio servo and a rather tasty Audi Quattro 23mm master cylinder, a rebuilt (well it will be) front sub frame including a E36 steering rack, Ive also added poly-sport arb bushes
and painted the 14mm spacers for the rack the same colour :o: and have new tca's, drop links and M3 eccentric lolly pop bushes etc to go back on.

Image

Image

I take absolute no credit for very much of this, I have tried my best to help but to be totally honest it all fazed me just a tad, Eko me son, my hat is fully off to you Sir :D

Last but not least 'shot of the day' I'm calling it ''In''

Image

The M50 is happily sat on E28 M5 engine mounts and all bolted up, I'll be up with the crack of Dawn tomorrow, I have no idea who Dawn is but I am in the process of getting a restraining order against her :squint:

Image

More pictures tomorrow :D

He he... No thats because I am currently playing with a front valance and was painting my bumpers :wink: (started the conversion Saturday!)
ricey46 wrote:Looking good guys, any more progress?? 8)
Well funny you say thats Ricey :D

Sunday: (I was fooked when I got in and couldn't get to the computer...)

Anywho - We got the prop on and bolted up to the M42 gear box, and also got the exhaust hanging on its mountings up to where the manifolds are going to meet the down pipes, Eko staggered the joins to allow enough room for the clamps, before fitting we had to modify the rear valance to allow for the standard 325i twin pipe system.

RandomSteve, Pete, Paul, Dave... Dave thats the one came down from Zummerset to cut and weld up the manifolds, help sort out the down pipes which just need finishing off and he also sorted out which wires go where on the loom side of things which saved us... Well I say us, Tony another 'little' job :D

Image

Before hand we ''mocked up'' a rather cunning E34 steering coupling combo, just to get the right measurement etc and to give the 'Exhaust team' something to work around :mad:

Image

The battery in the boot kit was also fitted and on went the rear strut brace, Tony has finished off the front sub frame which includes new TCA's, drop links, tie bars and M3 eccentric bushes.

The ecu is sat at home where the battery used to be, this will later get a fancy cover and an M3 backing plate to carry on from the M40 wiring cover :wink:

Image

Slight, well major snag with the Donner car
1. Not carrying a card to say what sort of organs it had up for grabs.
2. Being fitted with EWS means I cant go out and play :cry:

All the radiator is plumbed in and the Omega Air con fan is all bolted up, my camera has eaten the batteries so I couldn't take any pictures, Ive got loads of '80's throw back' pictures though :roll:

Image

I thinks thats about it?

Jaffro as Tony said it hasn't shown up... Damn the Royal Mail and EWS. :x

I'll post some more pictures of the progress tomorrow :D

Ive read about fitting the viscous but have never tried personally.
Is yours just the exhaust manifold to complete then?

Well It ran only on Carb cleaner when Dave came down :mad: and on a different ECU from either one of their cars ...

Tony's been pulling his hair out over it for the few weeks its taken, we popped over to get a fuel rail from the breakers today, got a red label ECU yesterday and we've just been out 'playing' and fitted the new rail now (in the p1ssing rain, again)

And................ Low and behold...

Its alive !! :banana:

What a great feeling, just a few things to finish off and Ill be able to road test it winkeye

Yea :P , Its was a complete ass :roll:

The Red label worked without any hassle and we didn't have to alter the loom at all...

The E34 that the engine came out of was fitted with about 5 fuel hoses and a gay after market pressure reg, this turned out to be the fuel problem, in hindsight it obvious why it was fitted now :mad:

But in between dodging all the sh!tty weather and locating the ECU etc it finely got done :D

As Andy said we finally got it running under its own steam :roll:
The fuel regulator had a 3rd fuel pipe connection actually coming out of the regulator which should obviouly have been a breather pipe to the manifold.
Looks like someone modified it when they fitted the aftermarket one.
Anyway picked up a replacement fuel rail and fitted it and fired up first time.

Enjoy it Andy :thumb:

Small pipe from the pressure regulator to the inlet manifold isn't a vent, it's the manifold pressure sensing pipe.
The fuel pressure needs to be constant across the injectors, whatever the position of the throttle, so the pressure regulator needs to know the pressure in the inlet manifold (where one end of the injectors are), so as to be able to adjust the fuel pressure to suit.
