M30 E30 official roll call thread

[dishwab]

That's what I was afraid of... Way out of my budget for this swap but they look great!

I was lucky to get my hands on a used one.
They are true pieces of art.





The invoice from 2009 stated £750 ex vat for the headers. (indeed - that's not a dollar sign)

[dishwab]

What headers are these?

So the car is finally just about as done as it's going to be for a while...
Located in Speicher, Germany

Fully rebuilt Euro M30B34 ( 218hp non-cat)
Motronic 1.3
4.10 diff
Custom equal length headers
Full 2.25" SS exhaust

I still have to get my fan wired up and the correct thermostat installed to get her running just right. I hope to get a cam, injectors and chip by the end of the year before I move back to Atlanta. We are supposed to be having a car show in August with dyno; hopefully I will be able to see what she's putting out. I can tell you that it sure does move with that 4.10 diff...

Project Update: Finally got some dyno tuning done using the Miller WAR chip. I still have an intermittent misfire so I will have to recheck all ignition parts and also wiring. In any event; misfire aside the car is running good with 205.4 hp at about 5100 rpm's and peak torque of 240 ft/lbs at about 4050 rpm's on a Dyno Dynamics machine. I still have some exhaust restriction with the B35 manifolds as well as some pipe restriction before the y pipe so there is more power on the table. I haven't been able to find reasonably priced decent fitting headers yet...but in any event not too bad for an "agricultural engine".

Well it finally runs right, so I suppose it belongs here now.

Well since I'm nearly done I guess I can post something:

89 Royal Blau vert with custom engine harness
B35 with 10.50 C.R. lightened and balanced stock rods (removed the pads on the big end)
worked head/N21 grind cam (simply beautiful courtesy of Paul Burke)
92.5 mm forged pistons which weigh 435 grams compared to stock 522 g.(also from Paul Burke)
standard size Glyco main and rod bearings
E28 535i radiatori
Getrag 260/6 from e34 with 533i flywheel balanced to E28 clutch & pp, UUC dssr
87 Eta big guibo driveshaft fits with no modification
home ported port matched intake, Bavauto long tube headers into y pipe with 2 1/2" single outlet to resonator to single inlet/outlet Walker muffler
3.5 Bar FPR gives about 50.8 psi so the injectors flow a bit over their 24 lb. rating.
67 mm bored throttle body
wide band o2 sensor
LS "D585 " truck coils on valve cover for sequential
Bosch 24 lb "715" injectors
home brew cold air box/filter setup with flow stack and SB cone filter
Revshift m20 motor mounts
E21 "green" transmission mounts
Rogue Engineering oil cannister cap with oil temp and pressure senders
MS3X in progress...


Otis' mounts in position 2 (gives me 1" between fan coupling on water pump and the radiator)
80 degree t stat
VR-1 20W50 oil
NGK BPR6ES plugs at .032"

I'm excited because next week I'm finally going for some dyno tuning. I had to track down a couple issues: fully bleeding the cooling system and not having one of the injector terminals fully seated. Oil temp and pressure looks good and my Spal fan kicks on and off as it should. Im going to a shop near Boston that has a Dyno Dynamics machine. They are supposedly known for low numbers /they calculate a 25% drivetrain loss so I'm interested in what numbers I get. Before that I am waiting on a new TPS to arrive because the current one has no continuity between pins 3 and 18 at full throttle and so the computer isn't getting the signal which means the tune that's in my chip isn't working to potential and is likely lean. Idle is currently Ok at about 900 rpm but I expect that too will improve because it seems a bit rich. I think the base 10 to 1 tune I got from Miller is for 19 lb. injectors. Most likely going to run near 50 lbs. of fuel pressure. I would like to run 91 octane but most of the stations don't have that grade; they have 89 and then jump to 93 so I will probably tune for 93. I'm going to keep a conservative redline of about 6500 rpm.

How'd you get the m20 harness under the stock m30 injector harness plastic cover thingy? I thought it was attached to the m30 harness.

It is attached. I had to cut it all out then I just put the M20 harness in there and tried to make it all neat. I had to dremel out certain areas to allow plugs to fit. Here is what it is like underneath the box:
