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

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

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

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

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...

little progress with my manifold

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.

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 · Post by **DieselBoost** » Dec 16, 2011 6:03 PM

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

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

DieselBoost · Post by **DieselBoost** » Dec 17, 2011 6:32 PM

More

DieselBoost · Post by **DieselBoost** » Dec 20, 2011 4:49 PM

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

Post by **Brad D.** » Dec 20, 2011 5:13 PM

That turned out great!

DieselBoost · Post by **DieselBoost** » Jan 02, 2012 3:59 PM

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 · Post by **DieselBoost** » Feb 23, 2012 5:16 PM

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...

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

My new 12mm 12.9 studs

I found some ventilation holes in bottom...

The exhaust

actually that silencer is dummy... with 3" straight pipe

Post by **mooseheadm5** » Apr 20, 2012 9:19 PM

What material are the studs made from? Studs like that with cut threads are not as strong as studs with rolled threads.

studs are made from 12.9 bolts... by local bolt shop
i know that cut thread is weaker but that is quite minor problem

This is what im doing now... i was little bit bored...

The wicked twins mitsubishi td04 from 525tds and masterpower 70super

For the intake side

Flap on the place

Downpipe with flap valve

and yes it is variable turbo system!

DieselBoost · Post by **DieselBoost** » Jun 25, 2012 4:19 PM

Moving on!

DieselBoost · Post by **DieselBoost** » Jun 26, 2012 5:05 PM

Again little progress with boostpipes

Almost all boost pipes where made from scrap metal pipes etc...
needs only little bit grinding and paint...

Post by **Brad D.** » Jun 26, 2012 8:07 PM

I await dyno numbers. It looks really sweet. ````
