It’s the turbine housing that hits? Is the downpipe flange also a different size? Thats going to be a big job. Is your hot side plumbing 2 separate ports?
Yes, the turbo housing hits. 4” downpipe on this new one. Gonna be fun! Yes, hot side is “divided” to the flange but was less important on the previous turbo because it was an open T4. The new one is a divided T4 and I’d like to keep it fully divided.
