Turbo b25 here, worth the "pain" to swap to 2.7i?

Probably a bit late, but I might as well chime in. I had everything I needed to build a 2.7i, but I decided to just turbo the stock (but, rebuilt) 2.5. I found the slightly larger displacement appealing, but the loss in compression ratio and combustion chamber efficiency (in an already inefficient engine) not worth it.

ALSO, offtopic but is there like a massive shortage on billet camshafts rn? Bimmerheads and IE are out of all billet ones. VAC cams are the only ones I can find right now. Also looked for the ppf z45 turbo cam but that's out also. Gonna need to do more research to find the one I want anyways

Top End Performance does the cams for IE/Bimmerheads, perhaps they’re out of blanks. Give them a call.
