M42 build for E36 Compact

[MrPhatBob]

I measured the lifters from the M42
Diameter: 34.99mm
Height: 26.00mm
Foot depth: 13.97mm

They show the same lifter specs for the 8V

So that looks to be the same, what I don't know about is the lash caps that sit between the lifter and the top of the valve.

Oh, and I went to buy ACL bearings today - ACL have gone out of business so no joy there.

VAC sells lash caps, but of course its never the cheapest option.

Also make sure to determine if you have 6mm or 7mm valve stems

[MrPhatBob]

6mm

Nice one Colin, I'll give that some reading tomorrow at work.

ACL Bearings have arrived

The next blight on my horizon are the oil squirters, I managed to loose a few of them in the hot wash (yeah I know, but they looked like they were press fit and that turned out not to be the case )

[wazzu70]

At least you realized you lost them. There have been MANY BMWengines put back together and run with a few missing squirters....and 0 oil pressure because of it!

[MrPhatBob]

It was only because I was washing the block and admiring the jet of cleaning solution that was squirting into the cylinder, I mused for a while on what method of controlling oil pressure they'd employed - and that's when it hit me.

Its the cost of the bloody things that I find upsetting.

[wazzu70]

I can understand frustration at parts cost!!

Im very excited to see how your engine turns out!

[MrPhatBob]

There are issues around feature creep with it... I'm drawing up a water pump blanking plate after colin86325's post. 
The water jet cutters http://www.h2oprofiling.co.uk/ have just texted me to say that my ITB to M42 head plate has been finished, so I'll have that to play with tomorrow.

[MrPhatBob]

I got my hands on the adaptor plate from H2O Profiling so I was able to start mounting the S50 bodies.

Cut three pockets to allow the M7 bolts to recess below the mating surface of the plate.
Cut four pockets 9.5mm dia 4mm deep, then tapped an M6x1mm thread to locate the ITBs on the plate.

[thebrelon]

is it the definitive intake runner length?
because all I could read on the subjet calls for longer intake runner to be able to tune the engine properly.

[MrPhatBob]

As I understand it the runner length is dictated by the length of the inlet trumpet, these ITBs normally bolt directly onto the head, in this case they're 16mm further from the ports than normal.  I will consider my options for trumpets once the engine starts coming together better.

[wazzu70]

Yeah, runner length includes the ITB assembly and trumpets. The trumpets are not shown in the picture.

[MrPhatBob]

Currently I have some velocity stacks from some Weber 45 carbs, they'll not be long enough to make much torque, there are options around, but the standard M3 ones should be plenty good enough

[thebrelon]

I learned something. thanks guys!
