Ben Pls

Glad to see this has caught on

Toe actually increases under droop (i know because I've measured it) so you really messed up here.

-10 internets, and please don't ban me.

But I think @snap is referring to when its actually planted on the ground.

Not sure what you mean, but here's the data from the e21 (if photodumpster works...):

Assuming that the e30 is similar, and that the lowest toe number is roughly ride-height, toe will increase as the vehicle is lifted.

These aren't the results I was expecting before I measured it. I had assumed the toe went negative under droop...

Jdesign

Ahhhhh I follow you now. That chart helps!

How the beep does camber change linearly, but toe is parabolic?!?!

Very interesting data though! Thanks for sharing

GunMetalGrey

Mike coming in with the high quality data!
I forgot that you had measured that stuff (E21) but it should be very similar to an E30 setup.

In other news, I still have no idea if/when this thing will ever run with an M21 again! Woo!

GunMetalGrey

What the heck. I decided to amuse myself at the fact that there are no M21 fuel pumps on ebay but searched anyway...

I'm going to call the shop that has my pump tomorrow and ask them for the numbers on the side to see if one of these will work.

Seriously dubyah teeaaa EEEEFFFFF. I guess if they are rare and hard to come by that makes sense for such a high value.

At this point I would start to question other means of diesel injection if you cant find a pump. Thats something I know very little about. Isnt the pump timed with the motor?

If it makes you guys feel any better, a high pressure fuel pump for the N54 isn't cheap either. And they do go bad.

N54 injectors commonly go bad, and they aren't cheap either!

Something that has eased my mind is the simplicity of the system, and the equivalent to what is being replacing.
Say I end up spending $1300 on the injectors and pump.

That is like replacing the following things on a gas m20: Fuel pump (high and low pressure if applicable), fuel pressure regulator, fuel injectors, ignition coil, plug wires, spark plugs, cap and rotor, crank sensor (kinda), idle control valve, ECU, and all associated hoses.

The pump and injectors are the only things that run this engine, and given how low the production numbers are it's hard to be mad at the cost.
I knew what I was getting myself into when I bought the engine, and unfortunately I have had to dive in further than desired, but that's how anything seems to go.

At the end of the day I'm excited about it, how many people do you know that have an M21 E30?
It's worth the cost for the cool factor.

I like your optimism

This pump right here is the only one on the internet that I can find right now that would work.
I contacted him to see if he would be willing to flex on price or verify condition.

GunMetalGrey

^lol at me for thinking it would work.
I looked at my pump and I have ver. 118-1. wtf does that even mean? Googling the bottom number on the pump yields just about nothing, and the top number just confirms that it is indeed a fuel pump. The hunt continues.

I picked up the pump from the shop (as seen above) and was given a slight tour of it by the guy.
Cam plate - Pitted

Cam Followers - Pitted

Shafty thingy - Rusted

Pump housing - rusted
Gear thingy - rusted and pitted

Pump housing - rusted

I ran up to the shop because the injector nozzles finally got delivered, and they were just in time for me to bring them there!

Very shiny, much precise!

I didn't really accomplish anything on the car this weekend, other than determining what I need to order for material to make motor mounts.

Yikes, so what are the downsides of just cleaning the pump as best you can and giviner? Is the pitting what was causing the external leak? The shop says it's hopeless?

They told me they wouldn't rebuild it, largely due to the fact that he said it would just cause larger issues down the road with the rust flaking off and getting stuck places.
There is a large O-ring that seals the back half (ish) of the pump and I'm willing to bet that's what gave out.

Not worth installing $600 worth of injectors and plugging one up two weeks later after rust keeps coming off.

Idk if you explained this already but why can't you just switch over to a different pump?

I have no clue if I can or not.
It's not worth $600 to buy a pump that may not work and then be stuck with a pump no one buys.

I've got a message out to see if I can use that rebuilt one on ebay that I posted.
There is just about zero info out there about these fuel pumps lol.

I would be interested in this too given how rare these pumps are. I'm not sure if it's useful since they are european pump specs but here is some detailed info about the various pumps on m21 d and td models.
