I finished this swap on my drift car in November. I'm not sure why but K&N RU-4960 was way too small to fit around my MAF. Mine came out of a 94 e34 525i (along with my engine) and I wound up using K&N RC-3250. My (janky) mount for the intake was just to put a zip tie around the MAF and through the mount for the M20 airbox. It's held up fine so far. I couldn't find that part number throttle cable and the forums seemed to indicate other ones would work. I got the throttle cable out of the same e34 that my engine came from and it's worked fine. I don't have the part number since it's buried in the engine bay. be careful buying ebay headers, I got a set that looked similar to Turner's old shorty swap headers but they wouldn't fit the engine block even after a ton of hammering. That was just money down the toilet.

Hey! Great video could you provide more information on the bracket to hold the maf/ intake

[@Puffyy100]

You don’t need any throttle cable. The m20 cable works just fine. And you haven’t covered anything with the exhaust system. “Just bring it to the exhaust shop” oh cmon dude. We trying to do all the work at home here.

[@slightlyMADcustoms]

Oh good to know. My understanding for exhaust is the m50/52 manifolds won’t line up with your existing e30 exhaust, but an exhaust shop can slightly alter the alignment for the flanges and get it connected up for you. So you can do 90% of the work.

I'm going through your videos on this subject and didn't see anything related to the Fuel Pressure Regulator. I have a m52b28 swapped e30 that was done by the previous owner. I found out they didn't provision for a FPR. I'm installing one now. Wanted to know if you have one on your swap?

[@slightlyMADcustoms]

We used the OEM setup from the M50 as the fuel pressure regulator mounts on the fuel rail so it is much more simple than the M52. The M52's FPR sits right after the fuel filter underneath the drivers footwell on the E36. So a couple options are to pull the FPR mount from a car with an M52 and adapt it or purchase an adjustable FPR from a company such as Aeromotive which would make it a much easier process. We definitely recommend having one!

[@Haubemotors]

Where did you put the iat since you took out the stock air box?

[@slightlyMADcustoms]

It goes into the bottom of the intake manifold

[@Haubemotors]

slightlyMADcustoms make my own hole for it to go in?

[@slightlyMADcustoms]

There should already be one I believe

[@hectorolmos1524]

questions, i am from california and i dont want to struggle passing emissions, does that mean I should use the exhaust for m5x meaning exhaust manifold and cats and then get a custom cat back exhaust fabricated?

[@slightlyMADcustoms]

Yes as long as you use any sort of cat in your exhaust system the car should pass the smog test.

@@slightlyMADcustoms thank you man really enjoyed the series.

[@slightlyMADcustoms]

No worries! Glad to help

Hello my friend I I’m doing swap with m52 to m52tu and have problems with the wiring connection the engine harness to the body harness can you help me with it ? Thanks best regards

[@slightlyMADcustoms]

NISHKIGOI KEEPErS I might be able to. You can message me here or on our social media platforms

[@thelastsamurai5857]

Ok my friend give me only the PIN number on the m52 x20 connector with color and destination to harness Thanks man

[@slightlyMADcustoms]

NISHKIGOI KEEPErS I found a couple really good diagrams on google. If you search “M52 X20 pinout” and go to images there’s some good ones. Hopefully that helps!

[@patrykkowalski6]

what about the itb`s? dont you wanna be cool?

[@slightlyMADcustoms]

patrykkowalski6 True true! There is a ITB kit sold online for the M5X engines. I considered going for it

[@patrykkowalski6]

@@slightlyMADcustoms ive got newer e46 m52tu engine and im stuck between m50 intake vs itb but the itb are almost 2k usd or more for me becouse of the shipping :(

[@slightlyMADcustoms]

patrykkowalski6 If you’re looking at the RHD ITB kit, send him a message and tell him Lukas from SlightlyMADCustoms sent you. He’s usually good about giving a little deal. The sound and cool factor would definitely be worth the money

[@patrykkowalski6]

@@slightlyMADcustoms i was looking at either rhd itb or at adapter plate for s54 itb but leaning towards the rhd since its cable driven and my m52 is cable driven aswell (i prefer it that way dunno why) i sent him a message on fb about whether should i buy m52 or m54 itb kit since i dont know which one will fit my m52tu engine

[@slightlyMADcustoms]

patrykkowalski6 the m52 kit will fit a M52TU. Do it! Then send us some videos!
