Dieselboost's 524Compound Biturbodiesel

[CoyoteStarfish]

I'm going to need one of these MLS gaskets. And a set of M51 head bolts. Mmmm... Can't wait!

[DieselBoost]

Im starting to make new exhaust manifold for my engine....

i sold my older one to my friend...

this manifold will be copy of Herlevi's Valtra pulling tractor exhaust manifold
Like in this http://irc-galleria.net/user/Laskeuma/picture/102080331

[DieselBoost]

Collector welded for cylinders 1 & 2

New turbine chamber for my turbo, bit larger than old one
Old was a/r 0.63 single inlet, this new is a/r 0.84 dual inlet


Me and my little turbo, now you can realize how large is turbo for 2.4litre diesel engine which have power goal of 350hp
and this turbo actually spools in about 2000rpm

[DieselBoost]

Project continues with new exhaust manifold, finally i got welding machine to adjustments...


It will be something like this...

i will make two collectors more for 1&2+3 and 6&5+4
and i will lift turbo a bit

Looks like an angry octopus with only 6 arms...


Love it.

Handsome devil, if you ask me. (yes homo)

[DieselBoost]

Few quite old pics... but i like these...


you can see how opel ascona c irmscher rear wing fits to e28
little fixing in future and it is perfect

[DieselBoost]

Project goes on....
few part where quite tricky to get on right place...
i did little mishap with measurements... so manifold is little bit too far from the engine... but i tried it to the car... and it fits...

i can still make final collectors turned little bit to the engine...
this way turbo will be in correct place...

[DieselBoost]

little progress with my manifold

[Aamir_bt]

this project is awesome! i was just thinking the other day if anybody was actually doing any kind of E28 diesel build, and that it would be kickass if someone was.

will be checking in for updates.

That is pretty bad.

[DieselBoost]

Ok... moving on with my project...

im working with my exhaust manifold and with little bit better finishing quality...

I tested these 1-2 pipes with paint... it looks quite good

[DieselBoost]

Almost ready... 1-2-3 welded up with collector...

only 1 collector and turbo flange + waste gate lines and it is ready!

More

[DieselBoost]

Its ready!!!
Now machining and heat treatment and i can bolt it on to my car!

[Brad D.]

That turned out great!

[DieselBoost]

Exhaust manifold number 2
2hour job and it is in this condition....
model is "straight & short"
this type manifold will be able to spool up much larger turbo in diesel....

I love turbo diesel cars!

[DieselBoost]

Finally i got inspired with my second exhaust manifold....
I spent about 20hours with this one (Total hours)
Heat treatment, machining and paint.... and it is ready...

[Sam 84, 533i]

Thank you for sharing your 524td. Don't stop posting pics. One of my favorite e28s!

[Nebraska_e28]

I has no parts for my car... so must do something creative...
this was project of the evening...
i spent only 2 hours with this one...

It is 3.5" absorption muffler made from old fire extinguisher!
inner perforated sheet tube is from old hydraulic filter
now little bit black matte paint and it is nice
