Finally had some time to realise side skirt mockup. I hope they don't look that block-like when finished with couple of details and corner radiuses Current wheels look sooo tiny, 650mm dia will look so much better without any tire strech.
Flat floor determined the skirt dimensions, floor will be about 20mm off the beams in front end with rubber mounts. Ride height I'm aiming is about 80mm.

Ser riktigt bra ut.. Kommer kunna skrämma en och anna tant med den när den är klar

Tack Gussam!

Lot's of foam and fiberglass stuff ahead... Made one little foam piece between the door and engine bay/wheel well, nice round edge for a better air flow, not to forget about the looks:

Kommer bli riktigt häftig när den är klar!

I've been searching for a suitable turbocharger lately, it's been too damn cold at the garage to do anything without keeping it warm continuously

At first I was looking for a Precision 6766, but then I noticed BorgWarner has released their new SX-E series, which might be a notable rival being also a little bit cheaper.
The one I'm interested is the S369 measured at 69/91mm comp and 74/80mm turbine.

I was wondering if anyone is running an older S366 in their M30B35 for reference? I'd like to see dynographs and boost/backpressure charts..
In case there's no info available, I'd probably go for a T4 1.00 A/R housing as my engine will be +10:1 CR revved up to 8k and supercharger will be helping at the low end.

Ideas, suggestions, help?

Recently I acquired 3D printer for rapid prototyping, one of the first test pieces was our designed BMW M10/M30 rocker arm. Got a few ideas how to utilize the printer with the E30

Looking good, what printer are you using?

Thanks!
It's chinese "Makerbot" copy, some double-checking of the bits and adjusting and it's was good to go.

Oh, I've been looking on getting myself a new printer and have been looking at one called CTC and is supposed to be a replica of a Ultimaker. Not that one you refer to?

Okay, there's a dozen of different brand replicas on market with different price tags. Flashforge, Qidi Tech, CTC... Take a look at Amazon and read the reviews + couple of days of searching with google and I think you'll find an adequate one for yourself

tumme upp! (Y)

Tack!

I got one control arm kit welded and painted for promotion use, almost looks like factory-made.

Amazing!

Earlier I inquired about S300 series turbochargers, but calculations proved there's no big enough turbine housings available, so... I had to look for something bigger. S467 would meet my requirements, but I wasn't sure if it would fit at all. Luckily I found one for testing, with 5" intake pipe:


This is a cast wheel unit with regular comp cover, I'll probably get the billet wheel unit with race cover:

Yesterday I spent a couple of moments looking and turning the turbo in different positions, tried different steel bends and ended up doing two collectors. The manifold will be equal length 6-2 type, I still need to make a turbo flange and get few more bigger diameter bends. But here's a start:

At some point I thought I will never manage to make an equal length manifold, but after few hours things were on the bright side.
Primaries are 42mm pipe which connect to a 3-1 collector, after that there's a short 51mm pipe/transition piece to the turbo flange, all pipes are equal length.


This is the sight at the end of the day:

Nice work!

looks really good!

Kul att följa, ser bra ut!
