Can you install a Holset HX40 turbo on a 91.5 Cummins, is so, are there any modifications required? This turbo has a 17cm housing - I have read many threads about 16's and 18's, just never came across anything about a 17cm. I do have a 4" exhaust system installed on my truck. Any sense, from practical experience, anyone can provide on reliability, economy, and performance is appreciated. Thank you!
