Calypsorot '90 325i Coupe

pulled these injectors out of the motor. Pulled the fuel rail/injectors off the old motor and plugged it into the harness for testing. Verified 70psi of fuel pressure before the FPR. Cranked the car and fuel sprayed but it wasn't a constant mist, I could just see droplets although they were firing upside down. Again verified that the injector harness has power and pulsing so that means everything ecu wise works?
After doing some reading next logical step would be to check impedance on the injectors? I'd like to hook the original set up to the motor too to see if they spray fuel any better. Any way of testing the FPR too? Also thinking it might be best to drain the fuel tank of year old gas to rule that out too.

Get fresh gas for sure, especially if it has any ethanol. The fpr is just a relief valve, so if you measure the right pressure at the rail it is working. Low pressure means it is leaking by or weak, high pressure could be from some clog on the return side.

Having moved to a new shop in July, This car hasn't had any attention between our schedules but we gave things another go yesterday and the car has started! Comparing notes between e30's it's seems to have been a combination of wiring issues and the fuel pressure regulator being bad. Don't really have a clear answer but the fpr was leaking this time after we re-wired the motor as we had planned to pull it for a m50.
@MattY bought a sedan (build thread will start soon) so just need to tidy up stuff under the car like installing the driveshaft, exhaust, subframe bushings being the major things before this is road worthy.
*knocks on wood* this will be at the picnic, hopefully the sedan too.

Does anyone else miss the suburban?

M50 swap it
the prophecy was set in stone and i am here to fufill it
-
will be great to see it, calypso is an awesome color.

I'm actually trying to find a decent turbo diesel truck myself the difference is I'll have a running BMW to take to events.

Forgot to update.
Sunday we connected the steering column, and while attaching the driveshaft we impromptu decided to do shifter bushings while we were under there.
Still trying to figure out the fuel leak. Chris suspects its the fuel rail, which we have a spare so we'll swap it in next time and see what that does.
Other than that leak, just needs the interior put together before it's in a good state.
Considering I wasn't a licensed driver when this car was obtained, it should be nice being finally able to drive this thing for once while I work on the alpine swap. Funny that it all came together exactly a year after we dropped in the new motor
-
did you do the trans selector when you were in there? tough to do with it still on the car?

we did just bushings and washers (garagistic delrin carrier shifter + rear) and that alone made a huge difference considering how sloppy it was. if we had more time it could've been done possibly but it took quite a bit to get it all in because the bushings were seriously rotted. lots of torching
but the good news is i'll have all new hardware on my alpine since it's a manual swap, and chris sourced me a z3 shifter for that guy. (i REALLY should make a build thread for that soon)

Couldn't remember if I did it or not when we swapped this motor/trans in but it didn't feel sloppy. I've done them in the car before, it isn't too bad.

the calypso has risen. and promptly fallen back down
we did this quick test drive last week after fixing a fuel leak (o ring in the fpr was forked), but i took the rear subframe apart to swap in the poly bushings i picked up last year. currently working on getting those swapped in.
after that it should just be interior. it seems to be running pretty solid.

So for a second there were 2 running/driving M20s in the state. Now its just Mr. Hundley again. Its nice to see progress on the Young BMW fleet nonetheless
AFAIK my sedan is the only one in the Madison area. I believe there are two coupes downtown but they're relatively stock. I'm of the belief that the calypso should be kept as stock as possible visually, it wasn't meant for the works with is lips and skirts
-
Didn't have time to update until now!
The bushing swap finally happened, and we also ran brand new nickel brake lines while the subframe was dropped (we literally tried EVERY method, and ultimately ended up dropping the whole thing.)
Also got the interior back together Friday night for the picnic. Carpet still needs a little cleaning, but I did do some carpet cleaning a while ago and it cleaned up real nice.
The first test drive with everything back together ran great! We made it to Waukesha without a hitch.
Next on the list is fixing the minor lower coolant hose leak, speedo sensor in the diff, odo gears, obc clock swap (current obc screen is smashed), and looking into the bumper. I have a brand new bumper in green/teal, just gotta see how it mounts up and then i'll look into getting it painted.

Look at you driving a running e30 on wibimmers. That's a small club to be in! Congrats!
