Lifted E30 V2

[GunMetalGrey]

I want to lower the front subframe a good bit (1" or more) but am sitting here debating what to do about the control arm bushing brackets, do I bring those down with? I don't enjoy the idea of that too much as their positioning is key to other geometry things, but I don't know if leaving them in the stock spot would be a good idea either...
Opinions?
Pic for reference (looks like they modified theirs to accept the e46 bushings)

In attempt to not disappoint

I finally have a fully functional blower motor! Replaced the resistor for it last night and now I have all fan speeds!

Got a cheap intercooler

Tried to track down my coolant leak, but I had waited too long so everything appeared to be dry. Judging by where it had drained I am kind of wondering if the heater core itself is leaking. Going to spend a bit more time on that one. 

I had been getting a fair bit of oil leaking when parked, from weird areas, and yesterday realized why. 
The crankcase vent has some sort of oil separator and I underestimated how much oil that would move. The stock setup has the oil drain line going into the oil pan below oil level, and I think I'm going to take that hose and feed it into the dipstick tube (add a tube) or see if there is somewhere on the e30 pan I can plumb it into. 

Large hose feeds over to the air filter as there is plenty of smoke that comes off that. 

I don't know if this has been seen in any of my pictures before. It's an Factory Five cobra rep. It's been amusing watching it go from a bare frame to where it is now.

That Cobra looks fun!

[stealthbimmer]

Get that cobra out on the ice and see what she can do.

That Cobra is cool. IDK if that would be my choice if I was going to build a F5 car, but all those kits are sweet no matter what they are. Its so temping too as you can build one for roughly$10K starting. 

I was able to clean that fan switch on my car. But I am cheap so im sure it will fail again.

I'm leaking fluids like they are going out of style.....

It looks like the heater core is leaking, and it is leaking enough to drain the expansion tank in a day or two. Gotta replace that.

I increased the fuel amount, and now the low pressure return on injector 6 is leaking a lot more than before. Gotta fix that.

I'm leaking oil out of the crankcase breather/separator. Gonna tap the return from that into the pan (like OE setup)

Adding more fuel was very amusing. Simple turn of a screw and now it is substantially faster. It also makes me want a different/new/bigger turbo knowing that the current one has compressor wheel wear and is likely less efficient than it should be.  
I took it out for a hot second last night, and I have more torque than traction down low, which is kind of a fun problem to have.

I wish it was always that easy.

Tried removing the #6 injector. 
27mm deep 1/2 drive with a 2.5 foot breaker bar. 
I got concerned as to what was going to give due to the amount of force I was applying, and nothing was moving. 

Yay stuck things!

those oversized vintage-styled wheels on the cobra are fricken amazing.

Soaked with PB blaster for a few days? The injectors on my truck take a 30mm socket and had a 3ft pipe on a 1/2in Craftsman breaker bar and it still took force to break 'em all loose.

Try to take it out when the engine is at operating temp.

Yeah I hit it with PB. Steel injector bodies in an aluminum head, should be a fun one.

Yeah that may be my next attempt.

I wish I would have thought of that before

It takes a while to realize the possibilities you have once you own a temp gun

But does it?

[GunMetalGrey]

I had my wheaties for breakfast yesterday. 

I really leaned on the breaker bar and it turned about 1/8th of a turn and then got super tight. I rocked it back and forth then pressed on. Eventually it got to the point where I could unscrew the injector by hand. 
Caked full of crap, it came out.

What the low pressure return should look like

What the low pressure return did look like

Now to find a "new" injector, or at least the back half.
I took it apart for fun.

Now I need to figure out how/why this engine is leaking so much oil/fluid. This is nuts...

[GunMetalGrey]

Super low RPM "pull" that I forgot to post. This was after turning up the fuel amount, and before adjusting the low boost fuel, smoke that black is going to drive my EGT's up too high! But it looks cool, and that's what it's all about right?

[Jdesign]

OH MAN that injector is junk. LOL

Check this out its filled with info.....

Quoted from a Bosch technical document then quotes from MyE28.com: 

These nozzles are known as Delay Pintle Nozzles, and are nearly always used with the Indirect Injection Engine, and have part numbers like, DN0S"D"299A.--The "D" in inverted commas, refers to Delay type nozzle.

"DN" "0" "S" D "299A"

"DN" referrs to Pintle type nozzle

"0" referrs to the spray angle, whether its defined as a number of degrees or not.

"S" refers to the size of nozzle body.

and "299A" refers to specific characteristics of that particular nozzle ( apart from this number its not possible to find the charaterictics of the nozzle from the makers)

Any letters before the "DN" refer to the maker, eg. B, C, K, R, V are all Lucas / Delphi maker codes, Bosch generally use just the basic number.

There is one in Bulgaria on Ebay for $40 if you cant find one. LOL

I've been eyeing the one in bulgaria up for awhile now.
I have spent plenty of time on the diesel section of myE28, and that chart is useful for nozzles, but doesn't have any info on the bodies. Which appears to be a common thing. 

Going to try the junkyard for some VW injector bodies, they look the exact same.

[Jdesign]

Good call. I would just go pocket some from a salvage yard and compare. They cant be far off, if not the same!
