Thanks for your post!  Yeah I'm biased but I think the price is a deal and a half.  

I have someone local who's strongly interested in the car as-is with the turbo setup.   I'll of course update the thread if the car is sold.

There's been fairly good interest in the setup/kit but no closed deals.  Seems like there are 2 types of folks out there:
- want to take the plunge but just don't have the funds (obviously I can't do anything about that)

- seriously interested but want to go straight to stage 2+ setups.  

not sure what to tell these guys other than to point out things like engine management, head gaskets etc are really up to them.  the kit does come with a brand new kinugawa wastegate actuator with multiple springs..  nothing stopping someone from getting an MS setup.  If you're really serious about stage2+ then this probably isn't the way to go, since that probably means buying a much more expensive turbo and possibly a different manifold too, maybe larger exhaust..

my conclusion here: this is probably best for someone with "stage 1" goals.

yeah tuning is stable car runs slightly lean off throttle and idle, a bit rich on throttle and on boost.  car makes about 6 psi per the boost gauge, pulls great.  all cooling issues resolved too.  the only nagging issue was around the oil return line.  details are in the threads posted above.

EDIT/UPDATE:  I have found what I believe to be a crack in the block.  Engine's being pulled and rebuilt.  more details here on e30tech.  doesn't affect any of the turbo stuff.

I was about to install the ostrich but have parked the car for now.  again, reason I'm selling is I have too many projects going on.  I plan to sell 2 of my 4 E30s in the next couple of months, along with these turbo bits.

As soon as I've pulled the parts off the car I'll post additional pics.  Most of the parts have < 200 miles on them (CHRA, new downpipe, cat, muffler, exhaust pipes and hardware, gauge setup etc), the rest appear to be in good shape.

I really don't want to part things out, but I am willing to sell off the full turbo exhaust system separate from the rest of the turbo bits.   I will not part out beyond that.  The price I'm asking for all this stuff is more than fair, and definitely less than what I've got into the car by a long shot.

UPDATE: I have a strong lead for the car including the turbo, so this may be gone soon.

UPDATE2:  I found an oil leak above the lower oil pan today and can not in good conscience sell the car in this condition because it's possible I have a cracked block or something based on what I'm seeing..  so the turbo bits are still available while I assess doing an engine rebuild.  The local buyer is still strongly interested - we agreed to get back in touch after the engine work's completed.  I need to decide whether to take this kit off the market or continue with the plan to put the engine back to stock

ADDED SOME PICS AND VIDEO

Also posted on m42club and e30tech

I have a troubleshooting thread for my 91 318is turbo setup over on e30tech. Since I have 3 other E30s I don't have the patience to keep working on this project, so I've decided to take the car back to stock condition and probably sell it.

I am selling the whole turbo package including the BEGI, intercooler, piping, BOV, M42 AFM with additional pigtail, turbo and mani, custom made down pipe and exhaust including cat and muffler for $900. I will make arrangements with the buyer on the shipping, which is probably about $100 in the continental US. If you have done any research at all you know this is a VERY good deal.

A bit of history: I bought this car last summer as a project car without an exhaust system. There was already a BEGI RRFPR, intercooler, BOV, Greddy TD04H-15G turbo and cut down turbo mani on the car when I bought it. Here's the new stuff I've added or bought since then, all with less than 200 miles on it or never used:

- M42 oil pan with turbo oil return tap in proper location

- brand new intercooler pipe kit with high quality clamps (never used)

- custom 2.5" 3 piece exhaust setup including hand welded down pipe with brand new magnaflow cat and muffler. the guy that did the work does show and collector cars and is highly sought after. Alot of pro labor went into this exhaust, which uses all factory hardware and mount points. it fits perfectly.

- brand new CHRA assembly for the Greddy TD04H-15G

- Kinugawa wastegate actuator with several springs from 0.5 to 1.5 bar (never used)

- 3 gauge ashtray area cluster pod (parker performance vinyl covered 3 hole bracket, VDO 15 psi boost, VDO oil pressure, Innovate G5 AFR

I am selling the whole package including the BEGI, intercooler, M42 AFM with additional pigtail, turbo and mani for $900. I will make arrangements with the buyer on the shipping, which is probably about $100 in the continental US.

Will be posting pics shortly. Please PM with offer. More info on the turbo setup at E30tech, 2 threads:

Not turbo related, but it looks like your a/c belt is not tight enough (post 1, pic 3)

yes car came that way.  started working on the a/c last summer but not done yet.  leaving it that way til the tune is stable.

as to the overheating, i found a crack and steam leak in the bleed screw hole on top of the radiator.  jb welded it.  also topped off coolant and bled the system.  temp seems to be ok now

I have been told by the guys over at Metric Mechanic that the stock 19# injectors are good for ~205HP with stock fuel pressure.

.... assuming that your stock engine was making ~140BHP, at 8PSI you should be making around 216BHP with an ideal tune.

.... You could try using stock injectors and then using an ARRFPR to set the max pressure to around 48 or 50PSI. That should really help the AFR under no boost, and hopefully get things leaned out a little better under boost.

good to know!!!  Given the experience so far, this is a strong argument to just put stock injectors back in.

good M42 fuel injector info here that backs up bmwman91's comments

EDIT:   It turns out the car came with stock injectors after all, contrary to what the PO said.  I rebuilt and reinstalled them.

Hi bradnic,

Your fuel mixture issues are somewhat the result of trying to tune everything by messing with the AFM. It will cause an offset at all readings, meaning that if you tweak it to run rich to make up for more air coming in under boost, it will also be reporting more air flow at idle. My advice is to return it to its original position since it will at least be giving accurate readings then.

I'm leaning your way on this (no pun intended).  with the initial setting the LC-1 was reading way lean at idle though.  how do I reconcile this lean LC-1 reading, especially when the PO told me they messed with the AFM (see below)?  I have to believe what I'm seeing there right?

Most people that do turbo fuel tuning without a custom chip or stand-alone ECU seem to do it with a mix of larger injectors and an adjustable rising-rate fuel pressure regulator (ARRFPR).

that seems to be exactly what the PO did here.  He also told me he'd used a wideband O2 sensor to tune the AFM.

With the stock chip in there, the only way to get a good mixture when not under boost (idle & cruising) is to leave the stock injectors in there since it is mapped for those.

conversely, since my injectors have been swapped and I'm using the factory ECU, if the AFM's adjusted back to its original position It'll run rich at idle right?

If you have an ARRFPR in there, you should be able to set it so that it will keep increasing the fuel pressure as the intake manifold pressure goes above atmospheric.

yup that's my understanding.  I pulled the signal vacuum on the BEGI at idle and adjusted it to 45psi fuel pressure.  I then have been trying to tweak the needle valve to adjust the rising rate under boost.  Hasn't been working very well.

Although the stock FPR is a rising-rate one, I think that it maxes out when the manifold pressure is at atmospheric (14.7PSIA).

hence the BEGI..

I have been told by the guys over at Metric Mechanic that the stock 19# injectors are good for ~205HP with stock fuel pressure.

good to know!!!  Given the experience so far, this is a strong argument to just put stock injectors back in.

I am running 24# ones on my Rally 2100 engine now, but those also came with a custom chip. Anyway, assuming that your stock engine was making ~140BHP, at 8PSI you should be making around 216BHP with an ideal tune. You could try using stock injectors and then using an ARRFPR to set the max pressure to around 48 or 50PSI. That should really help the AFR under no boost, and hopefully get things leaned out a little better under boost.

Sold.

How did things run before you messed with the AFM? Generally, you never want to mess with that.

it never idled worth a damn.  there were lots of problems to sort through though including the charge piping, oil return leak, fried CHRA...  it's been an exercise in patience to sort through all this.

definitely going back to stock injectors and starting the tuning over from scratch.

hey guys  thanks for the posts!!  lost track of the thread as I had some other stuff going on on e30tech.
will definitely replace the rubber fuel lines based on this feedback

current situation:

LC-1 installed
BEGi adjusted to 45psi with signal vacuum off
AFM tuned for 14.5 or so idle AFR
runs rich on accel (9-11 or so)
overheating on idle if you let the car sit still too long
check engine light now on steadily.
stomp test shows 1222 error, which I've read is probably related to a vacuum leak

I'm also still dealing with an oil return line leak too (PO tapped the pan too low - see 1st post).  
i have a replacement pan but need to be clear on what the fix needs to be - just higher?  
or - as I read somewhere but can't find now - a 2nd return through the oil sensor?)

Hi everyone

I bought a 91 318is M42 this summer that came with a Greddy TD04H-15G turbo, BEGI and 24# mustang injectors on it.  Using the stock ECU and hope to keep it that way.  I don't plan to exceed 6-8# of boost, so no stage 2/3, no large exhaust, no ARP studs etc.

I've taken it most of the way now to the point where it idle's well, pulls well, doesn't stall or overheat.  so great progress. Here's what I've done to the motor so far

- new CHRA as the old one was fried documented here
- LC-1 installed and O2 relay bridged per this install guide
- still pending is an oil pan swap as the PO welded in the return line tap too low in the pan.  car leaks oil constantly as a result.  new pan's already ordered.
- installed an LC-1 and fuel pressure gauge for the BEGI.  A basic AFR tune has been done by adjusting the AFM
- installed a custom 2.5" downpipe with magnaflow cat and muffler.  

Still using the integral wastegate+actuator that came with the turbo. I do have a kinugawa wastegate actuator with 5 springs, but have not installed it yet as i want the base tuning done first






Here's the present status
- idle fuel pressure is 45PSI
- AFM adjusted to 14.5 AFR
- car is idling at 800-900 RPM, but with vibration.  car stalled constantly before the AFM adjustment.  turned out per the LC-1 that it was set way lean.

Here's what the LC-1's reporting now when under load
- steady speed an RPM, no boost: 8-9 (very rich)
- boosted, accelerating: 18-22 (way lean)
- return to idle (like at a stop light):  goes lean 18-22, then settles back to 14.7 after 10-15 seconds
- LC-1 goes 'off line' when you take your foot off the gas (like it's maxed lean), then starts displaying readings again if you step on the pedal

Based on these readings I draw the following conclusions so far, but need advice from more experienced folks here

1) since the car's going rich off boost, I'm tempted to lean the AFM out
2) hopefully the idle will respond to the leaned out AFM setting and adjust back to stoich/14.7
3) for on boost the only thing I can do is mess with the needle valve on the BEGI

If (3) doesn't work then I will either increase fuel pressure at idle past 45 PSI or look into getting new fuel injectors.  I really don't know the condition of the mustang injectors as PO installed them and I haven't pulled or cleaned them myself.

Any/all advice sincerely appreciated
