OM606 Turbo Selection for Truck application
OM606 Turbo Selection for Truck application
As my truck is a manual, I'm looking for something that is able to start contributing some air as early as possible, 1200rpm would be great. The He221 seems popular, and the compressor map seems like it would work well, however I haven't been able to choose (or understand) which exhaust housing would work best. There doesn't seem to be a lot of information on turbine maps for this. They offer a 5, 5.5, 6, 7 and 8.5cm? to my knowledge, and for ~500$ new it's a very attractive option. 7cm seems popular, however I'm leaning towards the 5 or 5.5 to help with spool down low (I can only ever seem to find the 5.5 so that is likely what i would go with). I almost never exceed 4000rpm, so I'm ok if exhaust back pressure is non ideal at that RPM or higher.
I'm looking for some experience on the he221w exhaust housing size as well as if there might be a different commercially available turbos for this application. I was considering the variable geometry gt23v for awhile, however i heard there were multiple variants with large differences in efficiency. I'm open to compound setups (heard the R2S might work), however I'd prefer it be as bolt on as possible (have a variety of other projects going on, including one on the house that I need this truck to work for, so less downtime is huge).
(I recognize i'm trying to use this engine a little bit different than it was intended, however it's very close to an ideal setup so if I can get a better turbo match for the application I think it will work great)
thanks for the help!

I've been using the stock turbo and Baldur's ECU for the time being but have been looking to upgrade the turbo for a variety of reasons. There is a ton of information regarding turbos for these engines, however they seem focused on people using them in cars and for higher rpm power gains.
