Hi guys, Been rebuilding a Z3 with the M54 3.0 swap. Guy who swapped engine before me did a piss job..... Anyways.... Which MAF are you guys using? I have two different brand new MAFs already but not sure if they will also work with the m52tu TB...

Sunk cost fallacy is real. Have spent thousands restoring/rebuilding my 1999 328i through this pandemic and I hope this isn't the end of the line for its M52TU engine. I only use BMW/OE parts. Engine has overheated multiple times now. Issues began with a failed expansion tank 10k miles/3 years...

I'm putting a M52B28 TU in a kit car. It's actually from an E39, but I think the E46 group are a bit more responsive. I'm running GSXR 750 ITBs, and I've not got everything set up yet, and just want to understand why it's running so poor. At Idle it surges in revs, then drops and repeat. Here...

Hello, im thinking about turbocharging my e46 this coming winter and i have some questions. 1. Im not sure if i want to go with a topmount or a downmount turbo, so what are the pros and cons for each? 2. Can i run the stock ECU (MS42)? I will be keeping stock injectors, stock fuel pump, stock...

After repairing the MDK's 10-pin connector for M52TU by soldering, INPA started to show the following error: 208 revolution control not okay, EWS Car starts and drives as usual except the battery is not being charged. I haven't touched the EWS module, the wires look fine. Once, during...

Hello, I have a 99 323i M52TU that misfires consistently at high RPM. The car also seems to have very inconsistent power. Some days I can barely rev out the engine to 6900 (car is tuned for that) and some days I have waaaaay more power. When the car is running good, I can redline as much as I...

For a while now I have had an odd groaning sound when starting the engine. It's only when starting and doesn't happen when driving or at any other time. Happens during cold and warm starts. My vanos is being replaced this week, wonder if that could be related? Here is a link to the recording...

I recently replaced my valve cover gasket. New gasket kit and grommets are genuine BMW parts. The valve cover is not fully seated around the top right of the Vanos unit - see photos here Is this a normal condition or is this an issue with the valve cover - or something else? Engine is an M52TU.

Hello, Will the M54B30 intake camshaft fit on the M52B28TU intake side with the standard timing procedure? Do I have to turn the cam a little different than I would have to do with a standard cam? I know that this swap has been done but I couldn't find answers to my questions Thanks in Advance

My E46 328Ci with the M52TU engine starts to misfire after running for sometime. Changed the coil packs, spark plugs, fuel filter, pump and injectors recently. Scan gives an error code for an oxygen sensor, could this be the issue or does anyone have any idea what it could be? Thanks :bow:

Hey guys I edited my .bin exactly as it was depicted at the MS42 Wiki. The problem is, that there is no "bang" and the revs fall down very slowly. I tried de AD and C6 version. Has anyone had the same issue? What can I possibly do to get the pops and bangs? Cheers.

2000 328i m52tu engine In process of replacing dual vanos pistons seals. Have forgotten which piston went where, exhaust or intake cam side. They are labeled t-15 & t-16. Any ideas? Does it matter ? I've got a 50/50 shot :)

Had to take the car out tonight and it was very obviously misfiring from the get go. this has happened sometimes on cold starts before and has gone away shortly thereafter (think 5-10 seconds) so I started driving. The misfire continued for the whole 5 minute drive. When I dropped off what I...

Alright guys i'm as a loss. last weekend i did a valve cover and vanos seal replacement. After i got it all put back together it immidialaty stated throwing codes. I DID however forget to plug in the intake solenoid electrical connector. i took the car on a quick spin and quickly realized...

Hey all. I have a dd 330i that I'm very pleased with and I'd like to look at getting a second e46 as a project. Here's my idea. I want to turbo a bmw very badly. Maybe an e30. Maybe an e46. I've researched to death about boosting the m20, lots of people do that. Lots of people also...

Hello Guys I've been using this site for years for all my problem solving etc. Its finally come to the point were I'm facing a new problem. I've just done the m54b30 manifold swap into my m52tu, all went well pretty straight forward. On start up for the first time I had a rough idle and vacuum...

So I recently just bought this car from probably the biggest D bag on the planet because he fixed everything with superglue, zip ties, and electrical tape. I've been going through the car and fixing things that go wrong with it. I have run into an issue though. Every morning, like clockwork...

Here's the gist: I was driving down the road with cruise control on and all of a sudden when I went to accelerate past a couple cars, I felt a rough rumble that shook the car and diminished acceleration/horsepower. Since then, It happens every once in a while and I haven't been able to pinpoint...
