SC is off already and we will insert without anything on the inlet side.
Once in we will start the assembly as pipes and bends will have to be constructed insitu.
A few of the challenges will be getting the pipe from the intercooler back into the inlet manifold and clearing oil pipes and power steering pipes.
We shall also relocate the PS oil reservoir.
It promises to be a time consuming but not insurmountable.
We shall see.

We still need to design the pipes for the intercooler. The intercooler we were going to use turns out to be too small. So, I am looking at a Mishimoto Universal G line intercooler, which is the same one Active Autowerke uses. Problem... none in the country... and I really don't want to import again... FML.
Either that or we find one similar from Mr. Turbo.
If we don't come right soon, its not a train smash, as I need to run the motor in with the new piston rings. So, if we cannot get the intercooler done, we'll run 4psi boost from the charger, straight into the intake,no intercooler, and just take it slow for the first 1000km.
Almost there....

dont you still have an IC from the last supercharger build? I would just run that for now

We didn't use an intercooler on my 323i.
use alu pipe in place of misimoto IC for now :rollsmile: I assume the dimensions are available...
raise:
well least you chose Rwd so its a better base :rollsmile:

My new shiny Blow off Valve arrived today. Was going to use an HKS SQV blow off valve, but learn't that the spring used in the HKS blow off valve is too stiff for supercharger conversions and it doesn't close properly on idle. So... after much research and speaking to many guys over at M3forum who have supercharged M3's running Alpha n, I went ahead and imported a Tial Q 50mm Blow off Valve. It come's with a 2psi spring designed just for supercharging, unlike the HKS which is designed for Turbo applications and thus requires a much harder spring.
That being said, I am waiting for either Savspeed, Tune Tech, or Budler motorsports to open so I can get the required shims. Once I have the shims, the engine gets finished.
Still can't believe BMW don't stock shims for the e46 M3.
Word to the wise, if you want to build an ///M engine, prepare to import everything, cause BMW SA has fokol parts here.

A new pic and video update.
First, some pics of this awesome blow off Valve. It is the Tial Q 50mm, with 2psi supercharger spring. Active Autowerke use two Greddy style blow off valves on their manifold, mainly because a single greddy BOV does not move enough air. This two BOV setup is used on their latest Gen 6 and Gen 7 manifolds. I only have a single blow off valve on my manifold. Thus, for me to move enough air out, I needed a bigger BOV. Tial Q 50mm is the biggest and fastest. It releases air much faster than the stock Greddy Blow off Valves that are used by Active Autowerke. Many Supercharged M3 owners who have an active autowerke kit, have moved over to the Tial Q because of its awesome ability to vent air quickly, and its cool sound.
Many of those users tried the HKS sqv blow off valve that I was going to originally use, but discovered that the spring was too hard and the HKS would not open on idle. The BOV must stay open to insure a good idle and only close when the engine begins to rev. As soon as the engine stops revving, the BOV will open again, venting excess air. The BOV must be able to do this very quickly. VF Engineering, whom I acquired the original supercharger kit from, do not use a Blow off Valve. They recirculate the air back into the Supercharger intake pipes using a bypass valve. No cool dump sound. =( We have decided to go full blow off valve with Alpha N software.
That being said, here are the pics.
Now, onto the video. This is the video of the head assembly that was done on the 20th of December last year. Sounds so far away. ha ha.
It's shot in 1080p full HD. So, if you can, watch it in HD on youtube. Looks awesome me thinks..
and as always, Mods, if you can update title. Video and pic update on page 14. Thanks!!!!

This is what arrives in the box. First look.
Inside we find the Tial Q 50mm blow off Valve in black, with the Greddy style flange mount to fit my greddy mount on the intake manifold. Then we have a o-ring which sits between the blow off valve and the flange, which is kept secure via a hook clamp.
The intake manifold with original Greddy mount.
The Greddy mount flange sits atop the original greddy mount. The BOV is attached this this adapter.
