Marting,

I have no direct experience to offer you, but I intend to perform the same DIY in the near future, so don't mind me tagging along!

While I don't know where you are located or your proximity to parts and other resources, I thought I'd spew some thoughts and resources that I think you may find useful:

Fellow mud participant Tapage has installed a turbo and intercooler on his 60 series. I believe his threads are very useful for your purposes. Search his name for the appropriate threads detailing his journey through DIY problem/solution landia.

I read a paper somewhere online (not wikipedia) that indicated there is no performance gains from using 3" exhaust tubing. For a 2H motor, 2 1/2" is plenty of diameter to eliminate any restriction. However the area betwen the turbo outlet and the exhaust pipe is critical, requiring an expansion cone. I believe the cone recommended had a 15 degree angle for expansion, of approx 9" to 13" in length. Not sure about that. If you are interested I'll go hunt for that paper.

"I only want better driveability 150 bhp and 400nm would be nice." You will want to determine where on the RPM band you want this type of output, low, mid range or high RPMs. Deciding this will help those more knowledgable about specific turbos make a recommendation.

Obtaining a used turbo and adaptor might depend somewhat on your location. Resources where I live are certainly a constraint, so please continue to post your progress. I may choose to piggy back on your solutions!

One recommendation I recommend will be to get your motor prepared for the install: Injector cleaning/testing, IP diaphram replacement and installation of a pyrometer and oil temp gauge. You may also want to adjust your IP fuel delivery before the turbo install following the above in order to create a stable, measured baseline.

Please post pictures of your intercooler and chosen mounting location and method.

Thanks and best wishes,

Rick
