no indicator with old sensor, haven't bothered replacing the sensor yet.

What you could do is plug the DME's inlet cam sensor back and you'll have RPM's on the dash, or are you controlling the vanos ?

Ive always piggybacked onto the stock ecu, so it sees all the position sensors. I could easily fix this, i am just being lazy as I have the x3 coming.

I control vanos, yes.

I used to have rpm. Then I drove to jersey, parked for an hour, and there was no more rpm. Just like my it sensor died randomly one night.

Mysteries.

sure, i can give an update.

car is sitting in the garage now. i got home one night as it was overheating because the fan didn't want to turn on, ripped out all the wiring harness and threw it on the floor.

i'm going to concentrate on the supra for now, but while ordering parts for the supra, i got some extra 1000 cc injectors i will be using on the bmw along with the fuel pump that will come out of the supra.

supra is running AEM EMS v2 now, so that should free up a bunch of my time not screwing around with that to screw around with the bmw.

i have a 5 speed manual XI transmission sitting in the closet for the bmw to go in place of the automatic garbage. i need a flywheel, clutch, pedals, various hardware to attach all this stuff together which i will figure out when i get there.

i will also be getting a proper aluminum radiator and electric fan.

supra is getting a 72mm turbo, bugatti veyron fuel pump-based fuel system, 1000 cc injector dynamics a few other supporting mods here and there.

thanks for the offer. as i said, i've got a bunch of boxes coming for the supra, and i'm going to get that in a spot where it scares me shitless, then move onto the bmw, to once again, be scared shitless, albeit with a bit more leather and fake wood around me.

I'm moving to SEA/TAC area, if you need anything. LMK just pay shipping. Anything that doesn't fit in the car is going in the trash! 989 666 6469 Jay

little update.

I'm running out of reasonable **** to buy for the supra at this point, just have clutch driveshaft and suspension, so i was looking at the stuff i need for the bmw to get that back up and running, and it turned out to be stupid cheap - radiator, clutch/flywheel kit, pedals, new engine harness, new ecu.

my plan is to hack up one of the ecus so i don't have to ever cut up the harness anymore as that turns into a huge mess from what I've seen, have connectors on the stock ecu to connect megasquirt to it and take over the injector pins, ignition drivers, etc.

was going through some pictures of the hardware i set up for the bmw, and i'm not sure i've shown this pic before, shows the two extensions sitting on the inverted T4 e36 manifold, it's a pretty freaking tight fit there, so vband has to be used. that oil return flange is getting replaced once the supra is done-ish, so is a bunch of other stuff that got hacked up due to me not having a proper car to drive while i was building this.









so yeah, i still plan to get this thing back on the road, it just has to wait for the other toy to be finished:

the MILES of room that are available for turbo:





72mm turbo


the supra is donating a fuel pump to the bmw for the future along with some rather large injectors.

Hey Gennady,

I have a spare MS43 I was going to make my own harness for Vi-Pec, but ended up going with Pro-EFI. I'll give it to you for 50 bucks

what's the deal with proefi these days ? Is there a non-m offering that's plug and play-ish ? i actually got an AEM EMS v2 for the supra, cause i didn't want to screw around with megasquirt for that car.

They have a complete plug N play harness for the ms43, comes with Bosch igniters, boost solenoid, fuel pressure sensor, 5 bar MAP, and their wide band. can be installed in a like two hours It does have great engine safety features, traction control and much more that other ECUs cannot match.

I'll be writing a review for my pro 128 shortly, once I get everything setup.

i somehow lost the pictures... i'll be taking new ones.


i want to sell this project, i don't have the mental bandwidth to take care of this thing anymore. it was fun, but i'm somewhat done working on cars.

gonna revive this thread. i've more or less finished my supra (for the time being, until the bmw runs).

i've received a bunch of PMs since i've posted this thread about stuff. unfortunately, I lost all the original build pictures with the bottom mount, and the struggle for topmount.

i'll post some pictures here with progress, and update the first post for those interested.

i have no idea what's written in the thread anymore, so i'll simply repeat it:

I picked up the car sometime in 2007, 2004 325xi automatic.



it was comfy, but kind of gutless.

the automatic trans really didn't help either:



fastforward a few years ago, i decided to turbo it.

first attempt was with a straight forward bottom mount turbo on an ebay cast manifold, but who cares, bottom mount was a pain in the ass. the oil scavenge pump made me super nervous, and it just sucked to work on.
intake plumbing was also a massive pain due to the crazy stock intake maifold with the throttle body being hidden away below runner 3-4. the only neat thing about that manifold was how easy it was to get to the injectors. i ended up managing the engine with megasquirt3 and terribly hacked up stock harness. the automatic transmission was slightly modified to hold a bit more pressure, but i really didn't push it that much, only about 9 psi was all it ever saw.

the automatic transmission was managed with MegaShift, another megasquirt project that handles the auto transmissions, that was a massive pain as well, code was buggy and just a bad driving experience, so the decision to swap to a manual was made. then i let it sit for 3 years in the garage, or so.

here's all the juicy bits that people will likely want to see:

top mount turbo:



some of the downpipe pieces, the exhaust is vband from a pipe that's attached to the turbo (it's an ebay 5 bolt flange), vband was the only way to make this work. it's 2.5" due to space.





the manifold is a TCD unit made for m50 or m52 engine, mounted upside down, The manifold has a T4 flange, and one of the standard wastegate flanges. To get the turbo up to where it is, there are 2 extenders, a T4 to T3, and T3 to T3



it was the most straightforward way i could get it to mount, and it fits quite nicely.

naturally, with top mount, oil feed is easy:




and oil return is also, easy, as it's gravity powered.


the transmission is a 5 speed ZF (i think), bonus transfer case (non X-drive) bolted to the transmission already (on the top)



when i got it, 5th would not engage, it turned out that the 5th notch piston was completely frozen, perhaps cause it was cold, so i pulled them out, and now waiting for that mechanism replacement to ship from pelican.

clutch disk, cover, and flywheel are some sort of M3 items:





there's obviously other manual swap bits, new pedals, master/hydraulic lines, shifter, new bushings for everything. etc, i won't bother with those as you all have seen that stuff.

now, one of my annoyances when working on the old setup was the intake manifold, so i looked around and got one of those thai M50/M52/M54 manifolds, and it actually fits !
here are some pictures of the new intake manifold, fuel rail bracket, and cable throttle holder bracket:





and mounted on the car, for test fitting:



it is a stock deadhead (returnless-ish) fuel rail with some 660cc MSD injectors with the right connectors to use with stock harness. mount points have been changed, and i made that nifty fuel rail bracket to hold it all down. but a different fuel rail fits (with entry and exit). using the stock fuel pressure regulator/filter that comes with e46 and mounts under the car (boost-referenced)

now, for the management.

originally, when the car ran on megasquirt3, i had rushed the installation, and tapped all the wires under the hood at the harness, soldered to them, cut them, made it look gross, and basically had a really shitty mess of wires that was a pain to diagnose. ms3 worked perfectly fine, however, even ran both VANOS solenoids with tuning for that. I had J&S ultrasafeguard that managed knock, stock coils were ignited using some sort of toyota camry igniter, that megasquirt ran. as far as tuning the engine to run well, megasquirt was amazing, the wiring I created was not.

this time around, i'm doing it slightly different, i'm taking a stock ecu, tracing where stuff goes inside of it on the connector, and putting connectors on the outside that megasquirt will plug into

here is the ignition transistors taken over and wires soldered to the current-limiting transistors.



there is a small surface mount resistor near each transistor that the stock CPU controls these transistors via that has been desoldered.

the same thing has been done to the injector drivers here:


there are two automotive driver ICs with 20 legs each, that control 3 injectors each. legs have been lifted, and i soldered to the bottom of the connector.

same will be done to the vanos solenoid drivers, fan driver, fuel pump driver, idle controller, knock sensors, and whatever else comes up.

the whole point of this is to use a stock engine wiring harness without having to modify it.

i likely missed a thing here or there, if you have questions, let me know, and i'll go take pictures of what i've done, or explain what the plan is.

woh gurov,

way to revamp the thread! Thanks for the manifold idea, I want! I was going to get a TIG welder just to make a intake mani, but this may win me over depending on the price.

After running bottom mount for 20k miles, I'm getting worried of when the scavenge pump will fail, now I'm toying with the idea of going back to top-mount. I don't know how you managed the heat build up, Last time I was top-mount, and was street tuning (with lots of retarded timing) my coil pack distributor caught on fire! luckily I had a fire extinguisher with me.
