Twin 26 Turbos On A 30

[brada31ke70]

i have recently run a big end on my 26 and because i am a cheap bastard, i have decided to bin the 26 bottom end and replace it with a 30. i was not planing on changing anything but have noticed that there is only one oil return hole in the sump and the 26 has two, one for each turbo, should i bother drill and tapping another one into the sump, or maybe installing a 't' into the 30 drain hole and run both oil return lines into it, or just buy a single turbo inlet manifold and a turbo and do away with the twins.

if i go single, what turbos have people used, i would rather a bit more mid range, than a big punch at the end.

will the standard n1 twin 26 turbos run out of puff in the high rev range?

any input will be greatly appreciated, thank you.

If running a standard RB30 bottom end, I'd suggest spinning it to only about 7000RPM. 7500RPM max.

The N1 turbos flow enough to make 320 odd AWKW on a 26, drop boost a few PSi, and with lower rev limit you'll make "less" power, but you should pull the same torque. hence, a less stressed engine.
