differences between 2000 & 2002

[raf2000]

Hello, kinda a newbie again, moved and let my membership drop It's ok now renewed! Love the TDR magazine. Anyway, I have a 2000 AUTO SWB and put 275's in it shortly after buying when I found it difficult to pass Pinto's, etc @ highway speed. Loved it ever since. My father just ordered a 2002 with everything but the snow plow. I know there are turbo housing size differences and probably others to the engine. Can I put the Bosch 275's in a 2002 just as well as my 2000? Also, can I get my stock ones (and his) honed and matched to around 300+ HP? Est cost? ( Diesel Dynamics?) Thanks to any and all that respond.
