A Tale of 2 Sedans M42/S52

where did you get those from?

Euro grills? They were on sale at ECS, rare time I order from them over FCP Euro

That should be fine then, not sure why it would be blowing fuses?

I was running my stock aux fan from off to high and blowing fuses, it was drawing well over 30amps from a complete stop. Starting from off to low then to high (3 pole temp sensor) fixed my issue. I just run my puller (Spal 30100400) on a separate relay using the high speed signal.

I have been using a 35amp fuse with no blowing, so i suspect i am just hitting that 30amp mark. My father who does a lot of work with electronics suggested a slow blow fuse, so i have some 30amp slow blow fuses ordered.

in other news, the car has been running great and my oil temp gauge started working




i also picked up some new OEM euro grills and hood insulation which i need to tackle

Interesting, this is the first I have heard of this with Spal fans, I read it had 21 amp draw, I assumed that was peak. Do you suggest going to a 3 pole setup?

I was running my stock aux fan from off to high and blowing fuses, it was drawing well over 30amps from a complete stop. Starting from off to low then to high (3 pole temp sensor) fixed my issue. I just run my puller (Spal 30100400) on a separate relay using the high speed signal.

In regards to your throttle cable issue, you can run an M42 throttle cable. Fits perfectly Nice car, btw. makes me miss my S52 E30

Thanks, I ended up getting the modified E34 working well, wish I had known the M42 cable would have worked from the beginning...

If you're running the stock aux fan from off to high speed without first starting low speed, you will pull more than 30amp (especially on an older fan) and blow fuses.

Things have been slow, did a lot of work on my E91 and been driving the M42 around to iron out. Planning on wrapping that one in dark green, hoping this fall.

I did finish up the fog lights with some LED headlights, figured I would try out the 3000k since blue would look off IMO. Don't mind the ghetto front plate, i had to pass inspection....

looks sweet. those cans are pricey though.

yeah, and just too loud, had a few neighbors complain, I live on a few long steep roads and going 25mph up hill it's LOUD. Unfortunately It sounds like Syncro has since updated them but mine is going to need some custom work.

Been blowing my 30amp fuse for the fan, I pulled back everything I wired and found nothing going on, cannot figure it out as it doesn't seem to be consistent, but I may rewire everything for the fan from scratch since tapping into the high relay for the aux fan isn't working for me...


Otherwise, I have been working on the M42 318i, I pulled the leaky motor and refreshed the one from my M42 swap and put it in, hoping it will be solid. Went ahead and did new seals on the trans, filled with Pentosin ATF, swapped the water pump and bits from the other M42 and did the mess under the intake delete...







also refreshing some ROUGH foglights with new glass. The glass i got had no holes, so i decided to drill them out




Thinking of some LEDs for them, anyone with solid recommendations?

carpet looks nice. what did you use?

thanks, first i used Hi-Tech Vinyl/Carpet spray on the rear deck, but found it was a little crusty. For the carpet i ended up using ColorBond Black Carpet paint, took two cans and it came out great. Not crusty and great adhesion.

Been awhile, I have been busy pecking away at random projects. First off, I swapped my X3 booster thinking it had a vacuum leak and was causing my lean O2 codes. I went ahead and swapped that one out for a new one and did so without removing the intake manifold (but still a PITA). Still dealing with lean codes, thinking of swapping the Bremi MAF with a VDO (wish I had tuned for 3.5” since the Bosch 3.5” MAF is cheaper than a 3” these days…)


I also went to get the S52 inspected and failed for the following:
• Brake lights sometimes staying on
o Had to adjust the new brake booster so the pdeal was further back and more reliably hitting the brake light switch, since I had to take the pedal out I decided to install AKG Delrin brake and oilite brass clutch bushings
o First I tightened the pedal assembly nut too much which caused the brake pedal not bind a bit, did I do something wrong with install? Loosening the nut fixed it, but trying to see if this is indicative of some other issue.



• No windshield wiper fluid
o Didn’t know this was going to be checked, but was a pain. I replaced the lines and check valve, still leaked, so I purchased new elbows and added clamps to the check valve (before it only had clamps on the elbows). But no more leak!

• Side markers
o I had no bulbs, so I went ahead and installed LEDs all around the car

I also found the fan was not kicking on when I thought it would. I pulled the FAE 82C switch and tested it, found it did not kick on until 90C…. Had a hard time finding a replacement, found 82C on ECS for the E30, ordered and received a Febi #01102 which was labelled 90-95, I tested the switch just in case, confirmed it was 95C.. Contacted Customer Service and informed them, also told them the part number I needed was Febi 03280 as I was able to find that on the Febi Bilstein site. To Their credit, they overnighted me a new switch, but sent another 95C marked #01102…. Refunded my money and I went with FCP (would have originally had I known the febi part number from the start).
Will always test switches before install!


While waiting on my switche(s) for the S52, I decided to give the M42 car some TLC, since I still have that and my gf wants to drive it more.





Chased a water leak, confirmed sunroof drains and rocker drains were clear, cleaned out the elephant trunk, and still have the slightest bit of water coming in passenger door along the sill. So I put a hose inside the seal to help thicken it and make a better seal, seems to have stopped all but a slight drop of water…

But this got me motivated, so I pulled the carpet out to assess and clean it up.

Found no rust which was great, I pulled out some of the old sound deadening material, installed new and more sound deadening, and dyed the carpets since the gray was stained and dingy looking…


And I went ahead and did all new fluids in the CRX, shifted great before but I suspected the trans fluid had never been changed and was sitting at 77k, some Honda trans fluid for only $6 a quart and it shifted even better…
