:eek:

I need one for my fairmont! what transmission do you have behind it?
 
Four original 4-speed has broken. Now it has an ambulance 5speed transmission.


Little update is coming in sylinderhead.
Hydr lifters replace mechanical.









About that timing. Pump is 16 degrees before and advancer engrece that so when rpm are around 5500rpm is 46 degrees. If we go over 50 degrees then brechamber start broke.

Now power start drop at 5900rpm so thats why i think that NOS.
 
That's a sweet project. Start the nitrous off pretty small- .017 or .020" jet should be noticeable on that engine.
 
I would LOVE something like this in my fairmont... unfortunately a petrol mill will be the only affordable way to make any real power for me.

I'm guessing this car would weigh right at 2,900lbs with the iron headed Mercedes and 5sp... would be a blast with 400 diesel fueled horsepower :eek:

If you could figure out how to build that mechanical advance device to fit a P-7100 pump as used on the 5.9 Cummins, you could make a few dollars.

The engine looks great! What you gents can do with the Merc diesels is outstanding.
 
Holy sleeper batman!

Thanks for sharing your work with us. I always love seeing what can be done with cool european diesels.

If I ever happen to be in europe, I'll happily buy you a round of :Cheer:

New 170 injection pump, adjustable cam wheel, modified pre chambers and modified advance device has installed. Next sunday we see how much it pulls on dyno.

New cam profile is ready so i wait when i got machined cams on car.

 
I m thinking to go back compound setup. My gurrent turbo has 65mm kompressor and 69mm turbinewheel 85lbs/ 3pressure ratio.

Dont know for sure what size little turbo is good. Thinking 44mm billet kompressor and 49,4mm turbinewheel.

Ps. Dynod 477hp
