T-33 Experts! Allison J33 vs P&W J42

Tue Jul 08, 2025 4:15 pm

WIX Braintrust!

I'm looking for any T-33 experts here! Our museum has T-33 / TV-2 (57-6558) https://www.ctairandspace.org/t-33 that we hope to assemble and display within the next year, but have no Allison J33 that is supposed to go in it. We DO however have a Pratt & Whitney J42, which was the license built version of the Rolls-Royce Nene that powered the CT-133 Shooting Star.

So my question is: Could a J42 be installed in a T-33 / TV-2? Or would that require significant modifications? Are there major differences between the T-33 and CT-133? Any help would be appreciated!

Chris
