Rb26/30 Intercooler Piping Size

[eXquiSit]

with a precision 6266

i want quicker throttle response so i was thinking 2.5inch the whole way

not so fussed on getting big power, more response

what is everyone's thoughts?

cheers

Be a little more specific on your power target - one person's "big power" is another person's "nowhere near enough".

it 'should' easily make 300kw atw with that turbo

i want that 300 to be as early as possible

any more is a bonus

=)

what's the diameter of the turbo outlet

[Adriano]

^{2.5 is fine for over 300rwkw}

a little off topic but im very keen to see how this turbo goes on a rb30, how far away from running are you? what other supporting mods? fuel?

i was planning to run either a 6262 on my rb25/30 or a 6266 with 2.5" intercooler piping.

2.5"

What are the cooler inlet sizes? And what plenum inlet size?

Just keep them the same works fine

[eXquiSit]

i think cooler inlet sizes is 3inch

as is the rb26 plenum inlet

i was thinking of keepin it all the same as this is what came from factory on gtr's but i also have a preference of keeping lag to a minimum and thus the 2.5" piping to keep air speeds up!

IMO the air has to go through a 2.5" hole from turbo so why increase it, 2.5" to intercooler, but then from the intercooler to plenum go the size of the plenum as the motor needs air to draw from till the turbo can push air to it, but this is from the voice in my head
