    Looking at the wiring diagram for a 76, there should be a green/white striped wire coming off fuse 12 that was for the emissions stuff.
  2. xr4tic
    Not if the coil has a resistor wire running to it. What year is your car? If it's a later year and had emissions wiring that was removed, there should be a wire you could use off of that.

    All you need to do is disconnect the battery wire to terminal 87 and run an ignition powered wire to it, then it will only come on when the ignition is on.

    Depends on how you wired it up, I run ground through the thermal switch to trigger the relay (pin 85), then ignition power to the relay (pin 86), battery to pin 87, then the fan to pin 30

    you have the plate upside down in your pics, the short bolts go through the top strut mount (pointing down), the long bolts go up into the engine bay They should be long enough for a strut bar.

    If you think the injectors are too big, have you considered dropping the fuel pressure to reduce the amount of fuel injected? I think you said it's set for ~60psi which seems crazy high to me. Lowering it from 60psi to 45 psi would be ~25% reduction in flow.

    Got the trans mount in, almost looks like I know what I'm doing. I'll probably add another bolt further up the bend, possibly overkill? The IE downpipe is hitting the floorpan though, so it will be hammer time tomorrow.

    You can turbo a carb, but carbs are hard enough to tune without a turbo. I suspect you'll have to make some driveability compromises with a carb+turbo. EFI has so many benefits that I personally think it's almost mandatory for a turbo application. Just google it and I'm sure you'll come up with a lot of info - https://lmgtfy.com/?q=turbo+weber+38

    That will strictly depend on what parts you choose and who is doing the work. I would suggest two stages: 1st: Convert to EFI, get it running well 2nd: Add turbo, get it running well I suspect parts only cost for a budget EFI conversion would be in the $1500 - $2000 range (Megasquirt + used E30 EFI bits) Adding a turbo would be an additional $2000 - $3000 depending on which turbo you choose (GT28RS "disco potato" is what I've been eyeballing lately) That's assuming you're starting with a healthy M10

    Made a trans cross member for my Getrag 240 5 speed swap. It has the dual mount setup and the IE downpipe interferes with one of them. 1/4" flat bar that I bent using the HF "compact" bender (3 foot tall, has to be bolted to the floor, with a 4 foot handle) All welded up: \ I need to notch the brace for exhaust clearance still. Here's where it needs to fit, you can see the right mount is hitting the exhaust, so it's a tight fit through there.

    Sounds like fuel slosh, have you tried a full tank of gas? What is your fuel pump setup? Stock pickup?
  12. xr4tic
    Maybe stuck open injectors on 3 and 4? If it's pouring in fuel, it may foul the plugs before they can ignite it. Does the M42 use a wasted spark coil setup? I would double check the coil wiring, if two cylinder wires were swapped, the plug will spark, but it will be at the wrong time and not ignite
  13. xr4tic
    There's no fuel bowl to agitate, but maybe it would help with the sensors or the TPS setting, if it's adjustable, if some of the vibrations aren't transferred to the ITBs
  14. xr4tic
    Not just you. It's like the quoted pics aren't showing up and some are showing over the reply text

    I'm a big believer in MAF setups, it measures TRUE airflow, not a guesstimate made up by the ECU based on what you think the VE table is. I had issues with my ITB setup as well (motorcycle ITBs with MS1 Extra) I ran Alpha-N, couldn't get a good MAP signal. I did try hybrid-AlphaN which was slightly better. Also Issues with cold tuning - rough idle. I tried to plumb in an idle valve, but couldn't get it dialed in with the MS. The ITBs pointed into the grill, so airflow changed based on speed. 3000 RPM in 2nd was completely different than 3000 RPM in 4th (not a problem with a longitudinal motor) My vacuum log/idle valve attempt: I used a Carb-Tune to sync the throttle bodies.

    If you're looking for easy/tuneable, then ITBs probably isn't the way to go. The E30? EFI conversion has been done by multiple people and is well documented. Doesn't look as cool as ITBs, but is cheaper/easier to implement. That being said, I'm personally thinking about an ITB setup, just not sure which one. The RHD looks nice, but I doubt it fits with the stock brake booster. There are a few guys that have done a dbilas setup with good results (search the FAQ) https://dbilas-shop.com/en/intake-tract/throttle-body-kit/street-version/bmw/m10/5035/mutli-throttle-intake-system-for-bmw-e21-e30-1-5-2-0-8v-m10 The cheap ITB option is motorcycle ITBs, but it's a lot of custom work (I did it on a 16V VW Jetta before, I think I had ~$250 into it)

    How do the valves look? If there's no damage to the valve, you should be fine. I'm guessing the piston smacked a valve which lead to the engine being rebuilt. They probably just re-used the original pistons.

    Here's what I've bought so far: Bussmann 15303-4: Will hold 5 relays and 10 fuses Littelfuse HWB18: Wild hold 3 relays and 3 fuses Lots of Delphi Weatherpak connectors 800+ ft of TXL wire (12,14,18 GA in 11 colors) The Bussmann will be relocated under the dash. The HWB18 will replace the 2 relays for the lights + my electric fan relay in the engine compartment. I'm going to hide it in the headlight area. The horn relay will be moved inside. 3 of the 12 original fuses are for the headlights which I'm moving to the engine bay (fused off the battery) There's also one for the rear defrost that I don't have on my car, so that's 4 of the 12 that can go. I think for relays on the Bussmann, it will be: 2 for ignition, 1 for fuel pump, 2 for extra. I might remove one relay to add two more fuses, then I could have 1 relay and a couple fuses for an EFI system later on. I'm still trying to figure out where to put the 22-pin Delphi bulkhead connector though, it's way bigger than I thought.

    IIRC, the nuts are an odd size, 12mm wrench? Make sure you're using the right size socket. Bloody knuckles are just part of the experience. Removing the manifold is definitely the best. While it's off, you need to check the coolant ports for corrosion. When I cleaned mine up, I found several holes in the hose nipple and had to get another manifold. Plus, you need to remove a lot of material: More pics/details in my blog: https://www.bmw2002faq.com/blogs/entry/1186-sowhere-was-i-2016-catch-up-part-1/

    The MSD is just a fancy part-time multi-spark coil, it doesn't control timing, so it should be fine with the 123 dist. The big knock against the MSD is the tach will no longer work, you have to run an adapter. If you have the tach hooked up, try disconnecting it and see if that fixes your coolant gauge problem.

    I'm going the Bussmann RTMR route, relocating it into the cabin - http://www.bodenzord.com/archives/473 I got all the parts, the wiring harness is pulled out, and I've got my new wiring plans scribbled on various pieces of paper, but not quite ready to start wiring it up. Hopefully in the next month or so now that the weather is warming up.

    Looks to me like a Getrag 240 from an M42, mainly because it has the ears above the shift rod. I don't know if the bellhousing bolt pattern is the same or not (I don't think it is)
  23. xr4tic
    If you're just putting around and care more about originality, then go for it. Sounds like you have other cars you drive as well, so it's not really a waste if you can reuse them. As to not liking the way it shifts, that's the first complaint I've ever heard about that with the 245. Is it a mechanical issue? I can't imagine the original 4-speed would shift much better.

    I could never do a Mini-van, told myself I'd never do an SUV, but ended up with a Durango SRT for a family hauler (4 people) 475HP, AWD, Launch Mode...I'm starting to come around. And my wife even likes it.

    I was supposed to test that setup, except the mount they made was for the single mount 240, not the later style dual mount 240 trans. I never heard back from them after I pointed that out.
