Here is what they have done with the 262 (new) engines: They have cast replicas of the cases of the Jumos engines, they put the new GE engines inside the castings, with the same inlet and exhaust ports.

Quoted from http://www.Stormbirds.com where they made these replicas:

From the Jumo 004 to G.E.'s J-85

Clearly, an engine change was necessary to make this project viable, as the original Jumo 004B powerplants were decidedly temperamental and prone to frequent failure. After careful consideration of a wide variety of available engines, the General Electric J-85 / CJ-610 was selected as the replacement for the vintage Jumo powerplants.

Thanks to an innovative engine mounting concept, the J-85s are to be buried deep inside carefully-engineered castings of the original engine, so that correct visual appearance will be retained. The Jumo housings are also necessary to maintain the correct nacelle weight since the J-85 is a much lighter engine than its German predecessor

So theoretically, since the basic jet engine design (turbines, etc) is similar the intake and exhaust are exactly the same, the sounds should be pretty accurate.

PLEASE NOTE: I am not a aviation mechanic/engineer etc, I am not opening up a debate here, just trying to use some common sense reasoning.

THAT SAID, HERO, eeeeeeeeeeeeeexxxxxxxxxxxcellenttttttt work! I see you now have your work cut out for you

BTW: Hero If you still need my assistance with some recordings I have, please PM me a place that I can put them.
