Have your existing cams welded up and then reground. This will spare you the expense of machining your carriers and can give you better cam profiles than just grinding your stock cams. The price is a little more than grinding your stock cams, but actually is more affordable for what you get.
I had a company here in California weld up my intake cam and then reshape it. Works great, no complaints.

Whats the conclusion of the M64B44 valves??

Hi Thats very nice project you have there. May I know where did you get the throttle bodies and the gasket from (looks like from thick gasket with heat insulation).

Cause I am looking for 1 set of it as well. Thanks!!

I found a place that sells supertech valves that are direct fit to M42 in reasonable prices, so M62B44 valves might not be as attractivec choice as they seemed.

Here's the place: http://www.flatlander-ipp.co.uk/supertech/supertvalves-bmw.shtml

ITB's are from S50B30 (E36 M3) and so are the thick yellow ceramic insulators.

Mega II PCB 3.0 has been built, I still need to modify it to use COP ignition and to read second trigger (VR cam position sensor).

Old / New:

Next I need adapter between MS and OEM engine cable tree.

Hi! May I know where did you managed to source the ITBs and the Ceramic insulators from? Any contact of website of the vendor?

Thanks!

German ebay, whole lot cost about 250� if I recall right :cool:

Mega is almost ready! Uploaded SW and it seems to work but I haven't tested it thoroughly because I do not have stim board. Sensor conditioning circuits are ready too, still must build COP modification.

I also got S50B32 air filter + housing, should flow sooooooooooooo much better than wheezy stock housing while looking something that has been under the bonnet from factory :eek:

What's the diameter for the throttle plate for the ITB?

Boyracer · « **Reply #69 on:** March 20, 2009, 07:47:17 AM »

50 mm.

Boyracer · « **Reply #70 on:** June 25, 2009, 04:11:17 PM »

Long time and no updates so here comes one

Reground camshafts:

Spec sheet they were ground to:

So its:

intake 285 degrees / 11.95 mm
exhaust 280 degrees / 11.30 mm

Should be bit more lively than OEM or even Shrick copies I have now

Megasquirt II PCB 3.0 and Motronic adapter:

Three stage shift lights for mega:

Coil-on-Plug ignition drivers and idle control valve control transistor mounted on PCB:

Great Progress Boyracer. I also have a MSII PCB v3 setup that i intend on using....As far as i know though it is just a standard build.

Would you mind detailing the modifications you have made for the COP control or atleast pointing me to the information you used. Will you be using the extra software or just the latest release of MSII?

I'm not worried about the shift light because i have an AIMsports Mychron3 coming

But if you wouldn't mind throwing the details up I'm sure other people would be interested.

Thanks Chris

Very interesting thread!!!

I'm curently building a more or less stock M42 with about 150-160bhp or maybe a 2.1 stroker if I get bored:p

When all that is done and I have some money to spend, I'll be building a 2.0L using the M47 crank and S50B30 ITBs with hot cams and solid lifters etc so will be keeping an eye on this thread to see how yours is turning out:)

Neato! I'm interested to follow how it goes together and how the MSII PCB 3.0 works out.

Nice work and next the lame ass question: any timetable, do we see your racer during this summer on track?
