Alright guys, here is the story. I recently purchased an old idi engine from a local scrap yard for my build. I bought what i thought, and was told, was a 6.9 out of a 1986, however when i got her home and tore it down i knew instantly it was indeed a 7.3. Upon further inspection i discovered it is a 1993 turbo engine! Now the plan on this build was to use a pump from a cat 3208 along with twin turbos to reach into the 450-500 rwhp range. Knowing that the compression ratio would be insane for my goals, i had planned to use extra thick copper headgaskets to lower compression to around 17.5 to 1 compression while at the same time maintaining piston integrity. Now until today i had planned to simply use the same setup on this 7.3, but then i got an idea. If the wrist pins on the 7.3 idi turbo and psd are the same, wouldnt powerstroke pistons fit? And if they do fit, would they not lower the comp ratio to the same as the psd? Just trying to think of ways of keeping all that boost in the engine without shaving pistons. Thank you all for any info you can share.
