After the front fender was done I moved to the rear end to see if I could conjure it up to "mold ready". Massive filler layer hid under the paint. Round corner will be made into the mold, I find it easier than forming the metal mockup.

Postman brought me some goods; Davies Craig electric water pump and controller, now I can get rid of belt driven pump and thermostat housing, keep things simple 
Package also contained very compact cabin heater and a 16in radiator fan:

Projekti luettu läpi, mahtavaa työnjälkeä! Mistäpäin suomea tämä auto löytyy? 
Kiitos kiitos! Auto majailee Tampereen nurkilla, ensi kesänä tarkoitus kierrellä TimeAttack -sarjaa.
Tires arrived yesterday.. 
All I can say that's a lot of rubber! Although they look massive it will fit inside the fender strictly:
To avoid ruining them in the first practices I ordered E46 MK60 ABS/DSC unit, but only ABS will be used. I've seen people using MK60 standalone systems earlier, but the price of the complete harness was far out of my budget. Lately I started to sort out ABS system again and found out it could be done by myself maybe.
If anyone has a complete wiring diagram or MK60 ABS unit pin layout, please send me a message! All the info I've come across is kind of dispersed..

Tusen tack! 
Here's the Mk60 ABS unit. This thing is mini size compared to E30 pump + ecu!
I'm probably going to mount it in passenger's footwell, easy to route piping and electrics. Cabin heater will be bolted somehow over the IC:
ABS unit sits nice behind the aluminium foot rest:

BBS RF centres look much better with decent lips and barrels 11.5x17"

One day I tried how things fit in those RF wheels, 15mm spacer is minimum to clear the caliper but with 7" inner barrel it's pretty close to damper. So maybe a 6.5" barrel would be a better choice.
As someone might ask, here's the complete list of the parts:
-E36 M3 spindles
-E46 M3 OEM rotors with aluminum hub
-Brembo ZL/ZR18 calipers
-MagnusRacingTeam control arms with roll-center/bump steer adapters
-K-sport circuit dampers with custom valving and spring rates for my car

If anyone else is interested in similar front control arm kit, I've got a few extra sets in stock.
U.S. buyers please contact dylan@neuemotorsports.com he's making a pre-order.
Scandinavian buyers please contact info@motornord.se
If located elsewhere, please contact us magnusracingteam@gmail.com
"These control arms are made for E30 chassis to accept and correct the front end geometry using E36 or E36-M spindles.
E36-series spindles are often used to get 5-lug bolt pattern, but they also have better variety of brakes and coilovers than E30-series. Spindle itself has better geometry for racing as it is closer to E30 M3 variants.
The most notable advantages are correct wheel location and roll-center/bump steer correction which are decayed when substantially lowering the car. On the side the adapter plate also makes the steering ratio quicker. Kit only has about half the weight of orginal cast control arms.
The kit offers a chance to adjust the front end the way you want it; width, caster and anti-dive properties are all adjustable.
This is pure motorsports from the E30 DTM era."

Summer vacation is over... back to work and back to build the project.
I supposed to fabricate intake manifold right after the exhaust was done, but I ended up doing something else. Now I felt like doing aluminium parts. Previously I did aluminium charge pipes for my friends E21 turbo and welding felt pretty easy, maybe because of the thicker material or gained experience Anyway...
Got to start from somewhere, cut hole for IC to throttle body -pipe:
Making plenum backplate:
Our hydraulic press channel:
Now with integrated trumpets:
Next on to do -list are the runners, there's no too much space and I think I have to do some minor compromises.

...story of the intake manifold continues:
Tuned length 330mm:

Next thing was to make the airbox/plenum part. Space was limited but the volume will be near 9 liters when finished. I think there's no ultimate formula for calculating ideal volume, but 2-3 times the engine displacement should do when seeking at maximum power.
Started with two long radius elbows and a piece of straight tube:
Tried to fabricate a smooth air inlet transition piece, this should distribute air better than just an elbow welded to the bottom:

Lately I was browsing the interwebs looking for a throttle body to get the intake finished. No reason to go massive size flap so I wanted one to fit my alu elbows. I found a 80mm TB and same shop was selling v-band flanges suitable for the upcoming exhaust system, incidentally I found an oil filter relocation kit with thermostat, I think the blue color won't stay though...

One busy month behind, but not with the car.. Some progress with cylinder head and intake manifold.
Along with some other laser cutting parts I finally ordered an adapter plate for the gearbox. I've machined a centering tool to align everything perfectly before marking the holes.
Earlier when starting to make the intake, I was talking about one minor compromise..
There was no enough room for the supercharger or atleast it would have been very difficult to mount it with all the piping etc, so I decided to get rid of it.
Now it's only this baby taking care of the boost production Custom 1.10A/R exhaust housing is on it's way.
