A LOT OF QUESTIONS - M42 please, looking for new solutions

[Artem]

First of all, I am putting my new motor together, and I am doing a number of mods to it. I am leaving the newer pulleys on it, and adding on to the

One I am doing 100% is the COP mod, I already have the drawing and I can mill the thing asap - I will be getting the coils this weekend, so that will be that.

The next thing I need to do - the plastic waterpump pulley is sort of falling apart, so I would like to make another pulley on the lathe. In addition to that, I dont have the E36 power steering pump nor the pulley for that, so that will have to be machined as well.

This brings me to the first question: does anyone have any drawings/dimensions of a power steering pump pulley?

And has anyone tried to make mounts for the E30 power steering pump to the E36 motor alternator/PS pump mount? The drawings for that would also be VERY helpful.

Second question: Can I somehow swap the clutch from an E36/E34 AC compressor and fit it on an E30 compressor? cause my compressor is awesome, but the clutch will have to be off an E36 cause thats how the belts would work out.

And the final, so far -
I want to use a single mass flywheel, I want to keep the cost as low as possible and use the least amount of modifications possible - use the stock starter if possible. My budget is VERY low, I am cool with machining new stuff as that is free, but buying new things is a bit of a drag for me so far, as I wanted initially to just make this new engine work in my car and run well, but  I want to do it perfectly, so I have all new gaskets, new hoses, etc.


I will also do the elimination of the water hoses throughout the engine mod, it seems like a cool one.

In any

plastic water pump pulley?  The E30 has a steel pulley.  Are you referring to a different model?  The internal pump impellers could be plastic.

The E36 that I got the motor from uses a plastic waterpump puley.

I want to make the waterpump and the power steering pulleys. Does anyone know the dimensions for that?

I don't know if you will find dimensions for the parts online anywhere.  However, if you hit up an E36 forum and ask for some owners of E36's to help you by posting up the measurements you are seeking, they may be of better help since they have those specific parts on their engines.

I am assuming you need:

outer diameter of each pulley
inner diameter of each pulley (where the mounting bolt goes)
how many "ribs" each pulley has for the serpentine belt
the distance of space between each "rib" for proper belt contact
the width of the pulley (front to back)

Thanks a lot, Phil

I'll hit up some E36 forums, I have the water pump pulley and can measure it and stuff, but the power steering pump is a whole other story. I need to custom make pretty much everything that connects the motor to the pump - of course, I could delete the whole thing altogether, but I really want to avoid that, as I would like to have a completely working car for now.
