E46 330d projectcar

Recommended Posts

I got a cheap e46 330d Touring this summer with a 204hp engine. The car turned out to be in good shape, though, with a few areas that have teased me a little.

The idea was really that I would put it up sale when I got it in perfect condition, but just could not really make me sell it ;-) Now I've got some great Stuff for the engine, I'd always liked to have a 330d that I could work on and experiment without it being used as a daily car. It became this car;-)

Today, the last of my Christmas gift came to me and the car. New 535d nozzles, downpipe, new cast iron manifold and on top from Gottuned.com a special built hybrid turbo :-)

Turbo Specifications:

- reinforced journal bearings

- so called '360'

- CNC modification of turbine housing

- CNC modification of compressor housing

- Bigger KTS Turbo Billet X 65mm 6 + 6 blades

- Genuine Garrett larger turbine wheel GT23 from Mercedes AMG

- Genuine Garrett Housings and Exhaust manifold

- Dynamically Balanced

- Precise VNT adjustment

- CHRA is built using brand new parts

It will be an exciting project!

More to come ;-)

Yes it is, i look forward to getting the car ready for some spring tracday ;-)

The manifold is from X8R, the downpipe is from ECOTune, injectors from bmw 535d and the turbo is from Gottuned, the link is this:


Hi.. The injectors fits? The ecu runs them?

Finally I had some time to do a little on my project again.
I have had the manifold made so it can measure EGT and closed the EGR.
Have also made the turbo and downpipe ready for installation.
Hopefully I will soon have time to get started installing it 😉

Got some work done the last few days.

6 new 535d injectors got in the engine. The manifold is in as well as the new turbo with downpipe.

New i only need to do some small thing like mount sensors on the system and some service on the car. Then it can go and get testet before the remap.

Cant wait... :-)

Finally the car was done and it all works! It has now been remaped to work with a manual transmission and not kill it in a short time 😉

But there is much more to get form the engine, nozzles and turbo are at a maximum of 70%. But the engine is getting hot, so I must look at a larger intercooler and an upgrade of the cooling system.

Do any of you have any experience with it?

Nice work and nice results! Are you still driving the car, and how does it work?

I'm just about to purchase an '03 330CD manual and considering some options for it like re-mapping and LSD-ing it.

Yes they fit, but you need to remap the ecu for them to work. 

Has your fuel consumption changed and if so  what has your consumption changed to with the current turbo setup?
