So not an update on my vert but who cares

Seeing my car just sitting has been driving me nuts. Especially since I spent so much time with my wheel setup and they were just sitting there. Then I hit me! My wife has her badass M3! So I decided to roll and pull her fenders and put my setup on her car for an upcoming BMWCA show.

(I got ZERO love at the show btw. The old guy judging just couldn't understand why my tires didn't fit "correctly", haha)

Here's some pics

Making a little extra room (I had previously rolled her front fenders)




Fits like a glove! I love my vert, but I think M3 sedans will always be my favorite (at least when they look like this, haha)

Here's a few shots of the bottom of her car. Not a single leak in sight. It's the only way my crazy OCD brain will let me go to sleep at night.

Your wife's sedan looks very clean. Great progress so far, keep us updated on your vert!

[MrViicc]

You say you have OCD with no leaks insight, I just think you like shit done right (which is the way they should be). Great progress loved seeing you're vert transform

I have same thing with Mito center caps, can't find anything. So can you tell part number or something about them? Are they flat?

Back from the dead!!!
Its time to finish this build up

[vwgti16vt]

so where were we......

Ok, so as I mentioned after dealing with both types of the available M/S50 manifold swap kits I was very unimpressed. I knew the M/S50 manifold swap would be essential to making any real power so I decided I would create my own system.

The stock setup has the breather/ oil separation built into the intake manifold. The M/S50 engine didn't use a true oil separator and basically vented straight from the valve cover to the oil dip stick tube so drain any oil vented. Neither option in stock form was good enough!

For my boosted application I did NOT want my oil separator undergoing any positive pressure. On the stock M/S52 intake manifold this would take place. One of my problems with the available swap kits on the market were that they kept the oil separator attached to the intake manifold so that it would be under boost. I used the rally road kit on my wife's M3. Fitment was crap, the oil separator was hung so much lower that the drain hose came in contact with the motor mount bracket, the guy who owns the company was a dick when I called and asked some technical info and for our boosted application it required a bunch of 1 way check valves to keep boost from passing throw the oil separator and pressurizing the block. Although the check valves kept (when working) boost from entering the block it basically left me with zero negative crack case pressure under hard driving. Since crack case vacuum is very important to aid in ring sealing this was not going to be an option.

So basically I had 2 issues to deal with

1. Fitting the M/S50 intake manifold to the car and having it with with the obd2 emission controls and idle stabilizer valve
2. Oil operation

This is how I solved both problems.

Intake Manifold:

So this is what is looks like under your intake manifold, haha.
What you're looking at is a combo of wiring, coolant hoses and ,not pictured because it's attched to the stock intake manifold, the idle stabilization valve and oil separator


I decided that I was going to back date the entire intake manifold system. This meant running the OBD1 style harness bracket and ISV in the OBD1 position as well where it was attached to the wire harness bracket and connected to the intake manifold via a hose.

OBD1 bracket


OBD2 bracket


I figured since there weren't too many changes between M/S50 and M/S52's that it would be a direct bolt in swap...... It wasn't
But nothing a little brain storming and a die grinder couldn't fix.


This is what I ended up with. Perfect fit using all OEM mounting locations. I now had a place for my ISV to live.

I did have to loosen one of my knock sensors because its harness was in harms way. It must be torqued perfectly back to factory spec or it will be useless and be a PITA to track down and trouble shoot later

Here's the OEM hose that connects the ISV to the intake manifold.
All my vacuum lines were safety wired with stainless

I dont have a picture but I was able to verify that the OBD1 and OBD2 intake manifold temp sensors were the same other then the way they attach to the intake manifold. I ordered a new OBD1 version and installed it into the intake manifold before install. The plug ends are the same.

I needed vacuum lines for my fuel pressure regulator as well as the secondary air control solinoid
I pulled off the single vacuum port on the back of the manifold and split. Once again everything is stainless safety wired and new braided vacuum line.

Both cars look GREAT !

Not related to the intake manifold but only easily accessible while it was off the car were the 2 lines that run coolant through the throttle body.

I live in Arizona. Our winter time lows are in the mid 60's. That last thing I wanted was hot coolant running through my throttle body.

One of the lines was attached to the metal lower bypass coolant tube coming of the block. It was just capped with a heavy duty vacuum port plug and a stainless pinch clamp.

The upper hose came directly off the head. Initially I was going to cap it just like the other end until I noticed that it was actually a threaded fitting that went into the block. As luck would have it it was the same thread pitch as an oil drain plug. I grabbed a new plug and seal, hit it with a little anti seize and capped it off.

On the OBD2 intake manifold that bracket that held the oil serperator, ISV and air temp sensor also held the dip stick in place. I removed a small section of the bracket and attached it to the intake manifold using an existing mounting point.

OEM Bracket


I only need a small section. I know I could have easily fabbed something but I like the way this looked factory.



With everything taken care of under the intake manifold and on it it could finally be installed

A new set of gasket before install and that was that

A fresh set of new 42lbs injectors from my friends at RMS installed in the stock OBD2 fuel rail




As I mentioned earlier I kept my secondary air system in place. The factory mount for the control solenoid was no longer going to work. I drilled a few small holes for the 2 vacuum lines and mounted it on top of the intake manifold as low as possible. I was really happy with the clean look. Especially since at this point I wasn't sure if I was going to run the fuel rail cover.

The OEM oil separator drains into the dip stick tube. The dinan stage one kit on our M3 sedan uses the dip stick tube as a drain for the supercharger by adding an additional bung. Since my kit was put together for an ODB1 engine (dip stick tubes are not interchangeable) That's ok, I love making stuff!!!!

All i needed was the bung


My best friend is a certified aircraft welder. I can tig but this guy is the true master. Sometimes you gotta know when to let the specialists do there thing. I marked everything up and let him work his magic!


No surprise this is the perfection he handed back to me. That tube is just over a 1/2" wide. Stack of micro dimes!!!



A fresh coat of paint and a new oil ring and in it went

Small detail but I added a T to the brake master cylinder line to run the bypass valve.


Can you guys tell I love these wurth stainless pinch clamps!?! Cant beat them plus they look very oem
